Definitions
- the present invention is in the field of fabric treatment.
- it relates to a method of treating fabrics in a dyer comprising the step of delivering a composition onto the fabrics, the composition comprising a solvent and low stickiness active ingredients.
- tumble dryers have been used exclusively to dry wet items. Tumble dryers can also be used to treat fabrics. Treatments include refreshment, perfuming, softening and conditioning of the fabrics. Treatments of fabrics are usually performed in the presence of compositions especially designed to be used in a dryer.
- compositions for use in a tumble dryer can contribute to the build up of lint.
- This lint build up is especially acute in cases in which the composition is sprayed into the dryer.
- the small droplets of the spray can be carried by the air flow in the dryer, the droplets would eventually collide with parts of the dryer making the surfaces of the dryer sticky. Lint produced during the tumbling of the fabrics would stick to the now sticky surfaces of the dryer. This phenomenon can occur on the walls of the dryer, air duct, filter, filter guards and fan.
- the lint build up would cover the body of the tumble dryer and it could block internal parts, such as air ducts and filters, impairing the efficiency of the tumble dryer.
- An additional problem found with existing compositions is that the compositions stick to parts of the dryer and thereby reduce the amount of treatment composition delivered to the fabrics.
- the present invention is directed to a method of treating fabrics in a dryer.
- the method is suitable for the treatment of wet and dry fabrics.
- the method comprises the steps of placing fabrics into the dryer, applying a liquid composition onto the load and drying the fabrics.
- the composition can be delivered onto the load before, during and/or after the drying of the fabrics.
- the composition comprises a solvent and active ingredients. The composition does not become sticky during use, this avoids lint build up and optimizes the amount of active ingredients that goes onto the fabrics.
- the solvent of the composition of the invention evaporates during the drying step and the active ingredients deposit onto the fabrics.
- the active ingredients of the composition are such that they do not become sticky even when subjected to the high temperatures found in a dryer.
- At least 90%, preferably 95% and especially 98% of the solvent is evaporated when 100 ml of the composition are placed in an open container (circular glass beaker - radius 4cm, depth 8cm) and the container is placed in an oven at 90°C for 24 hours.
- the composition of the method of the invention preferably comprises from about 20 to about 99% by weight of the composition, more preferably from about 30 to about 98% by weight of the composition of solvent.
- Preferred solvent for use herein is water.
- the stickiness of the active ingredients is measured by evaporating the solvent of the composition to leave concentrated samples.
- the concentrated samples are rehydrated and the stickiness of O.lg of the sample is measured in a texture analyser as explained in more details herein below.
- the active ingredients do not go through a sticky phase during or after the solvent has being evaporated in an oven at 90°C for 24 hour.
- the resulting concentrated composition is rehydrated and left for 4 hours, the active ingredients are in the form of an oily liquid.
- the conditions described herein below are typically more stressed that those found in a tumble dryer, thus it can be concluded that the active ingredients do not go though a sticky phase during the drying process in the dryer.
- the actives ingredients i.e., the combination of all the single active ingredients
- each single active ingredient has a maximum stickiness of about 2800 Force (g), more preferably about 2500, even more preferably about 2000 and especially below 1800 Force (g).
- the composition of the method of the invention is delivered in the form of spray. This contributes to uniform distribution of the composition onto the treated fabrics.
- the method of the invention is suitable for treating dry fabrics. For example, fabrics that are not dirty and only need to be refreshed. Other treatments which are suitable applied according to the method of the invention include conditioning and softening of fabrics.
- the method of the invention is also suitable for treating wet fabrics.
- the treatment takes place concurrently to the drying of the fabrics.
- the composition can be delivered before or during the drying.
- perfume compositions comprise more than 10%, preferably more than 20% of weight of the active ingredients of perfume.
- the perfume composition comprises a high level of perfume ingredients of low volatility to avoid perfume evaporation during the drying.
- Suitable active ingredients for use in the composition of the method of the invention include any ingredient capable of conferring a benefit to fabrics, it also includes any ingredient that contribute to the stability of the composition, such as for example preservatives and ingredients that make the composition fabric substantive.
- Preferred active ingredients for use in the composition of the method of the invention include perfume, surfactant and preservative.
- composition is free of any ingredient that becomes sticky under the conditions specified herein below.
- composition is free from cyclodextrins (material widely used in fabric treatment perfume compositions).
- the present invention envisages a method of treating wet or dry fabrics in a dryer, the method includes the delivery of a composition onto the fabrics and drying of the fabrics (even if the fabrics are initially dry they will become wet after the application of the composition).
- the composition comprises a solvent and actives ingredients with low stickiness.
- the method of the invention avoids lint build up and allows optimum deposition of the active ingredients on the fabrics.
- the compositions for use in the method of the invention are aqueous compositions.
- Water is the main liquid carrier of the active ingredients due to its low cost, availability, safety, and environmental compatibility.
- water can be distilled, deionized, or tap water.
- Water not only serves as a liquid carrier for the active ingredients, but it can also provide some odor controlling effect of its own. It has been discovered that the intensity of odor generated by some polar, low molecular weight organic amines, acids, and mercaptans is reduced when the odor-contaminated fabrics are treated with an aqueous solution. Water is also very useful for fabric wrinkle removal or reduction. Without wishing to be bound by theory, it is believed that water breaks many intra-fiber and inter-fiber hydrogen bonds that keep the fabric in a wrinkle state. It also swells, lubricates and relaxes the fibers to help the wrinkle removal process.
- the solvent in addition to water, can contain a low molecular weight organic solvent that is highly soluble in water, e.g., ethanol, propanol, isopropanol, and the like, and mixtures thereof.
- Low molecular weight alcohols can help the treated fabric articles to dry faster and also provide some antimicrobial benefit.
- the optional water soluble low molecular weight solvent can be used at a level of up to about 50%, typically from about 0.1% to about 20%, preferably from about 0.2% to about 15%, more preferably from about 0.5% to about 10%, by weight of the total solvent.
- Factors that need to be considered when a high level of solvent is used in the composition are odor, flammability, and environment impact.
- the actives ingredients of the composition have a maximum stickiness (as measured under the conditions described herein) of about 2500 Force (g), preferably about 2000, more preferably about 1600 and especially about 1400 Force (g).
- each single active ingredient has a maximum stickiness of about 2800 Force (g), more preferably about 2500, even more preferably about 2000 and especially below 1800 Force (g). Stickiness measurement of the active ingredients
- Stickiness is measured by using a texture analyser.
- a 100 ml sample of a composition is placed in an open container (circular glass beaker - radius 4cm, depth 8cm) in an oven at 90 C for 24hours. This removes most of the solvent from the composition and leaves a concentrated sample of the active ingredients. This process of evaporation of the solvent from the sample is similar to that which would occur in a tumble drier during drying. The concentrated sample is then removed from the oven and allowed to cool to room temperature. The sample remains as an oily liquid when the solvent is evaporated and after the solvent is evaporated. Samples which go through a sticky phase as they solidify are outside the scope of the invention.
- the sample is re-hydrated with 2 ml of distilled water and stirred with a small spatula until a uniform concentrated solution is formed.
- the sample is left to rest for an hour.
- a 0.1 g of this sample is weighed into a well of a polycarbonate slide.
- the well is circular and has a depth of 4mm.
- the well is 2.5mm wider than probe and in such a position that the probe is centre to the well when the plate is clamped into place allowing equal gap around all sides.
- the stickiness measurement is then conducted on the sample using a Texture Analyser.
- the Texture Analyser for use herein is a TA-X2, with an aluminium probe.
- the probe has a smooth flat circular end with a diameter of 1.25 cm.
- the sample is placed in a polycarbonate slide having a 4mm deep circular well lathed into it. This well is 2.5mm wider than the probe (total diameter of about 1.5cm) and in such a position that the probe is centred to the well when the plate is clamped into place.
- the stickiness of an individual active component is measured by placing the component in neat form in the texture analyser.
- a preferred active ingredient for use herein is a perfume.
- perfume means a mixture of perfume materials.
- the composition for use in the method of the invention may comprise at least about 0.005 wt. %, preferably from about 0.005 wt. % to about 10 wt% more preferably from about 0.1 wt. % to about 2 wt. % of a perfume.
- the perfume preferably comprises at least about 30 wt.%, preferably from about 35 wt % to about 100 wt.

- the composition herein contains from about 0.005% to 1%, preferably from about 0.01% to about 0.5% and more preferably from a about 0.03% to about 0.3% by weight of the composition of a surfactant.
- Preferred surfactants for use herein include siloxane surfactants.
- Surfactant provides a low surface tension that permits the composition to spread readily and more uniformly on hydrophobic surfaces, such as polyester and nylon. It has been found that perfume compositions containing surfactant spreads satisfactorily on fabric articles. The spreading of the composition also allows it to dry faster, making the drying process more efficient. Furthermore, a composition containing a surfactant can penetrate hydrophobic, oily soil better for improved malodor control.
- the surfactant is also needed in a composition herein as a dispersing agent, an emulsifying agent and preferably as a solubilizing agent.
- the surfactant for use herein should be compatible with other components in the composition and not alter the character of the perfume.

Description
METHOD FOR TREATING FABRICS
TECHNICAL FIELD
The present invention is in the field of fabric treatment. In particular, it relates to a method of treating fabrics in a dyer comprising the step of delivering a composition onto the fabrics, the composition comprising a solvent and low stickiness active ingredients.
BACKGROUND OF THE INVENTION
Traditionally, tumble dryers have been used exclusively to dry wet items. Tumble dryers can also be used to treat fabrics. Treatments include refreshment, perfuming, softening and conditioning of the fabrics. Treatments of fabrics are usually performed in the presence of compositions especially designed to be used in a dryer.
It has been found that compositions for use in a tumble dryer can contribute to the build up of lint. This lint build up is especially acute in cases in which the composition is sprayed into the dryer. The small droplets of the spray can be carried by the air flow in the dryer, the droplets would eventually collide with parts of the dryer making the surfaces of the dryer sticky. Lint produced during the tumbling of the fabrics would stick to the now sticky surfaces of the dryer. This phenomenon can occur on the walls of the dryer, air duct, filter, filter guards and fan. The lint build up would cover the body of the tumble dryer and it could block internal parts, such as air ducts and filters, impairing the efficiency of the tumble dryer. An additional problem found with existing compositions is that the compositions stick to parts of the dryer and thereby reduce the amount of treatment composition delivered to the fabrics.
In view of the above problems there is need to provide a composition that does not give rise to lint build up in a tumble dryer and which provides for an optimised use of the composition.
SUMMARY OF THE INVENTION
The present invention is directed to a method of treating fabrics in a dryer. The method is suitable for the treatment of wet and dry fabrics. The method comprises the steps of placing fabrics into the dryer, applying a liquid composition onto the load and drying the fabrics. The composition can be delivered onto the load before, during and/or after the drying of the fabrics. The composition comprises a solvent and active ingredients. The composition does not become
sticky during use, this avoids lint build up and optimizes the amount of active ingredients that goes onto the fabrics.
The solvent of the composition of the invention evaporates during the drying step and the active ingredients deposit onto the fabrics. The active ingredients of the composition are such that they do not become sticky even when subjected to the high temperatures found in a dryer.
At least 90%, preferably 95% and especially 98% of the solvent is evaporated when 100 ml of the composition are placed in an open container (circular glass beaker - radius 4cm, depth 8cm) and the container is placed in an oven at 90°C for 24 hours. The composition of the method of the invention preferably comprises from about 20 to about 99% by weight of the composition, more preferably from about 30 to about 98% by weight of the composition of solvent. Preferred solvent for use herein is water.
The stickiness of the active ingredients is measured by evaporating the solvent of the composition to leave concentrated samples. The concentrated samples are rehydrated and the stickiness of O.lg of the sample is measured in a texture analyser as explained in more details herein below.
The active ingredients do not go through a sticky phase during or after the solvent has being evaporated in an oven at 90°C for 24 hour. The resulting concentrated composition is rehydrated and left for 4 hours, the active ingredients are in the form of an oily liquid. The conditions described herein below are typically more stressed that those found in a tumble dryer, thus it can be concluded that the active ingredients do not go though a sticky phase during the drying process in the dryer.
The actives ingredients (i.e., the combination of all the single active ingredients) have a maximum stickiness of about 2500 Force (g), preferably about 2000, more preferably about 1600 and especially about 1400 Force (g). Preferably each single active ingredient has a maximum stickiness of about 2800 Force (g), more preferably about 2500, even more preferably about 2000 and especially below 1800 Force (g).
In a preferred embodiment, the composition of the method of the invention is delivered in the form of spray. This contributes to uniform distribution of the composition onto the treated fabrics.
The method of the invention is suitable for treating dry fabrics. For example, fabrics that are not dirty and only need to be refreshed. Other treatments which are suitable applied according to the method of the invention include conditioning and softening of fabrics.
The method of the invention is also suitable for treating wet fabrics. The treatment takes place concurrently to the drying of the fabrics. The composition can be delivered before or during the drying.
Any type of treatment composition, provided that fulfil the claimed requirements, can be used herein. Especially preferred for use herein are perfume compositions. Perfume compositions comprise more than 10%, preferably more than 20% of weight of the active ingredients of perfume. Preferably, the perfume composition comprises a high level of perfume ingredients of low volatility to avoid perfume evaporation during the drying.
Suitable active ingredients for use in the composition of the method of the invention include any ingredient capable of conferring a benefit to fabrics, it also includes any ingredient that contribute to the stability of the composition, such as for example preservatives and ingredients that make the composition fabric substantive. Preferred active ingredients for use in the composition of the method of the invention include perfume, surfactant and preservative.
The composition is free of any ingredient that becomes sticky under the conditions specified herein below. For example the composition is free from cyclodextrins (material widely used in fabric treatment perfume compositions).
DETAILED DESCRIPTION OF THE INVENTION
The present invention envisages a method of treating wet or dry fabrics in a dryer, the method includes the delivery of a composition onto the fabrics and drying of the fabrics (even if the fabrics are initially dry they will become wet after the application of the composition). The composition comprises a solvent and actives ingredients with low stickiness. The method of the
invention avoids lint build up and allows optimum deposition of the active ingredients on the fabrics.
As used herein, the articles "a" and "an", when used in a claim, are understood to mean one or more of the material that is claimed or described.
Solvent
Preferably the compositions for use in the method of the invention are aqueous compositions. Water is the main liquid carrier of the active ingredients due to its low cost, availability, safety, and environmental compatibility. As used herein, water can be distilled, deionized, or tap water. Water not only serves as a liquid carrier for the active ingredients, but it can also provide some odor controlling effect of its own. It has been discovered that the intensity of odor generated by some polar, low molecular weight organic amines, acids, and mercaptans is reduced when the odor-contaminated fabrics are treated with an aqueous solution. Water is also very useful for fabric wrinkle removal or reduction. Without wishing to be bound by theory, it is believed that water breaks many intra-fiber and inter-fiber hydrogen bonds that keep the fabric in a wrinkle state. It also swells, lubricates and relaxes the fibers to help the wrinkle removal process.
Optionally, in addition to water, the solvent can contain a low molecular weight organic solvent that is highly soluble in water, e.g., ethanol, propanol, isopropanol, and the like, and mixtures thereof. Low molecular weight alcohols can help the treated fabric articles to dry faster and also provide some antimicrobial benefit. The optional water soluble low molecular weight solvent can be used at a level of up to about 50%, typically from about 0.1% to about 20%, preferably from about 0.2% to about 15%, more preferably from about 0.5% to about 10%, by weight of the total solvent. Factors that need to be considered when a high level of solvent is used in the composition are odor, flammability, and environment impact.
Active ingredients
The actives ingredients of the composition have a maximum stickiness (as measured under the conditions described herein) of about 2500 Force (g), preferably about 2000, more preferably about 1600 and especially about 1400 Force (g). Preferably each single active ingredient has a maximum stickiness of about 2800 Force (g), more preferably about 2500, even more preferably about 2000 and especially below 1800 Force (g).
Stickiness measurement of the active ingredients
Stickiness is measured by using a texture analyser.
A 100 ml sample of a composition is placed in an open container (circular glass beaker - radius 4cm, depth 8cm) in an oven at 90 C for 24hours. This removes most of the solvent from the composition and leaves a concentrated sample of the active ingredients. This process of evaporation of the solvent from the sample is similar to that which would occur in a tumble drier during drying. The concentrated sample is then removed from the oven and allowed to cool to room temperature. The sample remains as an oily liquid when the solvent is evaporated and after the solvent is evaporated. Samples which go through a sticky phase as they solidify are outside the scope of the invention.
The sample is re-hydrated with 2 ml of distilled water and stirred with a small spatula until a uniform concentrated solution is formed. The sample is left to rest for an hour. A 0.1 g of this sample is weighed into a well of a polycarbonate slide. The well is circular and has a depth of 4mm. The well is 2.5mm wider than probe and in such a position that the probe is centre to the well when the plate is clamped into place allowing equal gap around all sides. The stickiness measurement is then conducted on the sample using a Texture Analyser.
The Texture Analyser for use herein is a TA-X2, with an aluminium probe. The probe has a smooth flat circular end with a diameter of 1.25 cm. The sample is placed in a polycarbonate slide having a 4mm deep circular well lathed into it. This well is 2.5mm wider than the probe (total diameter of about 1.5cm) and in such a position that the probe is centred to the well when the plate is clamped into place.
The following parameters are used:
Initial probe height - 10 mm
Speed at which the probe is lowered - lmm/s
Apply force - lOOOg
Hold - 60sec
Speed at which the probe is raised- 0.5mm/s to a high of 10mm.
The polycarbonate slide is placed into the holder and clamped into place so that the probe is centred to the well containing the sample. The Texture Analyser program is then run on the sample and the force (in grams) required to separate the two surfaces is recorded. This force (in grams) is the stickiness of the active ingredients.
The stickiness of an individual active component is measured by placing the component in neat form in the texture analyser.

Surfactant
In a preferred embodiment, the composition herein contains from about 0.005% to 1%, preferably from about 0.01% to about 0.5% and more preferably from a about 0.03% to about 0.3% by weight of the composition of a surfactant. Preferred surfactants for use herein include siloxane surfactants. Surfactant provides a low surface tension that permits the composition to spread readily and more uniformly on hydrophobic surfaces, such as polyester and nylon. It has been found that perfume compositions containing surfactant spreads satisfactorily on fabric articles. The spreading of the composition also allows it to dry faster, making the drying process more efficient. Furthermore, a composition containing a surfactant can penetrate hydrophobic, oily soil better for improved malodor control. The surfactant is also needed in a composition herein as a dispersing agent, an emulsifying agent and preferably as a solubilizing agent. The surfactant for use herein should be compatible with other components in the composition and not alter the character of the perfume.
Suitable siloxane surfactants for use herein are the polyalkyleneoxide polysiloxanes having a dimethyl polysiloxane hydrophobic moiety and one or more hydrophilic polyalkylene side chains and have the general formula:
R1— (CH3)2SiO— [(CH3)2SiO]a— [(CH3)(R1)SiO]b— Si(CH3)2— R1
wherein a + b are from about 1 to about 50, alternatively from about 3 to about 30, alternatively from about 10 to about 25, and each R1 is the same or different and is selected from the group consisting of methyl and a poly(ethyleneoxide/propyleneoxide) copolymer group having the general formula:
-(CH2)n 0(C2 H4 0)c (C3 H6 0)D R2 with at least one R1 being a poly(ethyleneoxide/propyleneoxide) copolymer group, and wherein n is 3 or 4, alternatively 3; total c (for all polyalkyleneoxy side groups) has a value of from about 1 to about 100, alternatively from about 6 to about 100; total d is from 0 to about 14, alternatively from 0 to about 3 ; and alternatively d is 0; total c+d has a value of from about 5 to about 150, alternatively from about 9 to about 100 and each is the same or different and is selected from the group consisting of hydrogen, an alkyl having 1 to 4 carbon atoms, and an acetyl group, alternatively hydrogen and methyl group.
Examples of this type of surfactant are the Silwet® Hydrostable 68, 611, and 212 available Momentive Performance Materials. Other representative Silwet surfactants are as follows.
Name Average MW Average a+b Avera i;ge total c
L-7608 600 1 9
L-7607 1,000 2 17
L-77 600 1 9
L-7605 6,000 20 99
L-7604 4,000 21 53

The molecular weight of the polyalkyleneoxy group (R1) is less than or equal to about 10,000. Alternatively, the molecular weight of the polyalkyleneoxy group is less than or equal to about 8,000, and alternatively ranges from about 300 to about 5,000. Thus, the values of c and d can be those numbers which provide molecular weights within these ranges. However, the number of ethyleneoxy units (-C2H4O) in the polyether chain (R1) must be sufficient to render the polyalkyleneoxide polysiloxane water dispersible or water soluble. If propyleneoxy groups are present in the polyalkylenoxy chain, they can be distributed randomly in the chain or exist as blocks. Besides surface activity, polyalkyleneoxide polysiloxane surfactants can also provide other benefits, such as antistatic benefits, lubricity and softness to fabrics.
The preparation of polyalkyleneoxide polysiloxanes is well known in the art. Polyalkyleneoxide polysiloxanes suitable for the composition of the present invention can be prepared according to the procedure set forth in U.S. Pat. No. 3,299,112, incorporated herein by reference.
Preservative
The composition can comprise from about 0.0001 % to about 2% of antimicrobial preservative. Preferably from about 0.0002% to about 1%, more preferably from about 0.0003% to about 0.5%, most preferably from about 0.0004% to about 0.1%, by weight of the composition.
The preservative keeps the composition free from microorganisms and subsequent microbial growth that can result in unsightly and/or malodorous issues. The preservative is effective for inhibiting and/or regulating microbial growth in order to increase storage stability of the perfume composition. Preferably the preservative is water-soluble and is solubilised in the composition of the method of the invention.
It is preferable to use a broad spectrum preservative, e.g., one that is effective on both bacteria (both gram positive and gram negative) and fungi. A limited spectrum preservative, e.g., one that is only effective on a single group of microorganisms, e.g., fungi, can be used in combination with a broad spectrum preservative or other limited spectrum preservatives with complimentary and/or supplementary activity. A mixture of broad spectrum preservatives can also be used. In some cases where a specific group of microbial contaminants is problematic (such as Gram negatives), aminocarboxylate chelators (also referred herein as chelants) may be used alone or as potentiators in conjunction with other preservatives. These chelators which include, e.g., ethylenediaminetetraacetic acid (EDTA), hydroxyethylenediaminetriacetic acid, diethylenetriaminepentaacetic acid, and other aminocarboxylate chelators, and mixtures thereof, and their salts, and mixtures thereof, can increase preservative effectiveness against Gram-negative bacteria, especially Pseudomonas species.
Antimicrobial preservatives useful in the present invention include biocidal compounds, i.e., substances that kill microorganisms, or biostatic compounds, i.e., substances that inhibit and/or regulate the growth of microorganisms.
Preferred antimicrobial preservatives are those that are water-soluble and are effective at low levels. Water-soluble preservatives useful in the present invention are those that have a solubility in water of at least about 0.3 g per 100 ml of water, i.e., greater than about 0.3% at room temperature, preferably greater than about 0.5% at room temperature.
The preservative can be any organic preservative material which will not cause damage to fabric appearance, e.g., discoloration, coloration, bleaching. The water-soluble preservatives of the composition of the invention are selected from organic sulfur compounds, halogenated compounds, cyclic organic nitrogen compounds, low molecular weight aldehydes, quaternary ammonium compounds, dehydroacetic acid, phenyl and phenolic compounds, parabens and mixtures thereof. Preferably the composition of the invention is free from quaternary ammonium compounds. Due to the nature of these species aggregates may form which can cause blockages in the delivery system or potential build up within the appliance itself.
The following are preservatives for use in the composition of the present invention.
(1). Organic Sulfur Compounds
Preferred water-soluble preservatives for use in the present invention are organic sulfur compounds. Some non-limiting examples of organic sulfur compounds suitable for use in the present invention are:
