Description

Preservation of soaked wipes

The invention relates to a preservation system with which flexible carriers, for example cleaning and care wipes, which are equipped with an aqueous impregnating composition, can be preserved against microbial spoilage over a long period of time.

Flexible carriers, in particular wipes, sponges and pads, which are impregnated or impregnated with liquid cosmetic compositions, are very popular with consumers. They are time-saving, clean and hygienic to use. Suitable carriers are cloths made of fabrics as well as nonwoven nonwovens made of cotton fibers or of synthetic or mixed fibers, for the manufacture of which mostly polypropylene, polyester or viscose is used. Sponges made of polyurethane, rubber and similar materials are also suitable. The carriers equipped with a cosmetic cleaning and possibly care and active ingredient soaking solution are usually packed in a moist state and can be conveniently transported anywhere and used immediately if necessary, even if, for example, no running water is available for cleaning.

Due to the moisture content and the large carrier surface, adequate preservation of such products against microbial spoilage, especially during storage, is an absolute necessity. To this end, the person skilled in the art has numerous known preservatives which are approved for use in cosmetic products.

In contrast to disinfectants and fumigants, which have a quick killing effect on microorganisms (microbicidal) and are mostly toxic, preservatives only inhibit the growth and multiplication of the microorganisms over a longer period of time, i.e. they tend to have a microbiostatic effect in the concentrations usually used. However, if the dosage is sufficient, a preservative can kill the microorganisms present within a few days if the initial germ content of the cosmetic product is low and subsequent contamination with microorganisms is excluded. Germination of bacterial spores and the formation of Mycotoxins from mold can also be suppressed by preservatives. Most preservatives are especially effective against yeast and mold (fungistatic). Only a few can be used effectively against bacteria (bacteriostatic).

Known preservatives that are approved in the Cosmetics Ordinance are in particular phenoxyethanol, imidazolidinyl urea (Germall ^® 115 from ISP), methyldibromo glutaronitrile, polyaminopropyl biguanide, chlorothymol, chloroacetamide, chlorhexidine diacetate, chlorhexidine digluconate, quaternium-15,

Hexadecylpyridinium chloride, iodopropynyl butyl carbamate, 1,3-dimethylol-4,4-dimethylhydantoin, polyhexamethyl-bis-carbamidine, zinc omadine, 4-chloro-3,5-dimethylphenol, 4-isopropyl-3-methylphenol, triclosan, and in particular the methyl, ethyl, propyl and butyl esters of para-hydroxybenzoic acid.

The effect of some of the known preservatives is based on their ability to release formaldehyde, which has a preservative effect. Formaldehyde as well as the esters of para-hydroxybenzoic acid ("parabens") can, however, have a sensitizing effect on particularly sensitive consumers under unfavorable conditions. For the production of cosmetic compositions, especially for sensitive skin, it would therefore be desirable to largely replace such preservatives with more compatible compounds. A reduction in the use of halogen-substituted compounds is also desirable for reasons of skin compatibility and, not least, for ecological reasons.

Furthermore, it would be desirable for the person skilled in the art if the preservative would have an additional cosmetic benefit, not least in order to save material and costs.

Known preservatives which are also approved as a food additive and which do not have the disadvantages described above or have them only to a minor extent are salicylic acid, benzoic acid, propionic acid, dehydroacetic acid (3-acetyl-6-methyl-2H-pyran-2,4 (3H) - dione) and sorbic acid.

Since these preservatives react weakly acidic and only neutral, undissociated molecules can pass through the cell membrane and get into the cell interior of the microbes, these preservatives can only be used in more acidic cosmetic compositions. The lower the pH in such a composition and the smaller the substance-specific dissociation constant of the respective acidic preservative, the greater the undissociated, antimicrobially effective proportion of this preservative.

The sole use of the acids mentioned for the long-term stable preservation of cosmetic impregnation compositions for wipes, pads and sponges has so far not proven feasible. The present invention overcomes this deficiency in the prior art.

An object of the present invention was to provide a cosmetic product in the form of a flexible carrier which has been provided with an aqueous impregnating composition and is preserved in a long-term stable manner.

Another object of the present invention was to provide a cosmetic product in the form of a flexible carrier which is provided with an aqueous impregnating composition and is long-term stable and is compatible with sensitive skin.

Another object of the present invention was to provide a cosmetic product in the form of a flexible one, which was provided with an aqueous impregnating composition

Carrier, which is preserved long-term stable with the gain of a cosmetic additive.

These objects are achieved by a flexible carrier equipped with an aqueous impregnation composition for the non-therapeutic cosmetic or dermatological treatment of the skin, hair, mucous membrane and appendages of the skin, the aqueous impregnation composition comprising at least one organic acid effective as a preservative, selected from salicylic acid, Benzoic acid, propionic acid, dehydroacetic acid (3-acetyl-6-methyl-2H-pyran-2,4 (3H) -dione) and sorbic acid as well as the physiologically compatible water-soluble metal salts of these acids, contains and with 0.1-10% by weight of a corresponding acid-base pair is buffered in such a way that it has a pH of 2.5-6.0 both before the carrier is equipped and after two months of storage on the carrier equipped with it. The present invention furthermore relates to the use of an aqueous impregnating composition which comprises at least one organic acid which acts as a preservative and is selected from salicylic acid, benzoic acid, propionic acid and dehydroacetic acid (3-acetyl-6-methyl-2H-pyran-2,4 (3H) -dione) and sorbic acid as well as the physiologically compatible water-soluble metal salts of these acids, and is buffered with 0.1-10% by weight of a corresponding acid-base pair in such a way that it is used both before the carrier is finished and after two months of storage on the carrier equipped with it has a pH value of 2.5 - 6.0, to equip flexible carriers for non-therapeutic cosmetic or dermatological treatment of the skin, hair, mucous membrane and skin appendages.

According to the invention, physiologically compatible metal salts include the sodium,

Potassium, magnesium and optionally calcium salts of salicylic acid, benzoic acid,

To understand propionic acid, dehydroacetic acid and sorbic acid, provided that they are sufficiently water-soluble.

According to the invention, “water-soluble” means a solubility of at least 1 g of salt per

100 g aqueous solution at 20 ° C.

The sodium and potassium salts are particularly preferred according to the invention.

According to the invention, the salicylic acid, benzoic acid, propionic acid, dehydroacetic acid and sorbic acid and their salts mentioned are used in amounts of 0.02-1% by weight, preferably 0.1-0.8% by weight and particularly preferably 0.1-0. 5% by weight, based in each case on the weight of the impregnation composition.

In a preferred embodiment of the invention, the organic acid effective as a preservative is selected from salicylic acid and its physiologically tolerable water-soluble salts, in particular sodium salicylate. In addition to its preservative effect, salicylic acid also has cosmetic active properties. The cosmetics specialist uses the keratolytic effect of salicylic acid, for example, to treat blemished skin and acne.

Corresponding acid-base pairs suitable according to the invention are aqueous buffer solutions which the aqueous impregnating compositions according to the invention both in the pH range from 2.5 to 6.0, preferably in the pH, before the carrier has been finished and after two months of storage on the carrier equipped with them Stabilize range of 3.5 - 5.5, and particularly preferably in the pH range of 4.0 to 5.0. Aqueous solutions of citric acid and its sodium salts, in particular trisodium citrate, tartaric acid and its potassium salts, in particular potassium hydrogen tartrate, and phthalic acid and its potassium salts, in particular potassium hydrogen phthalate, are preferred. A particularly preferred buffer system is formed from citric acid and the sodium toprate. Other buffer systems, for example acetic acid / sodium acetate, are in principle also suitable according to the invention. However, due to the smell of vinegar, such a buffer is not acceptable for the production of a cosmetic market product.

The long-term stability of the preservation system according to the invention depends crucially on the capacity of the buffer system used. The capacity of the buffer system used is sufficient according to the invention if the aqueous impregnation compositions according to the invention have a pH in the abovementioned ranges both before the carrier has been finished and after two months of storage on the carrier equipped with them. For this purpose, the aqueous impregnation composition according to the invention is first adjusted to the desired pH. The flexible carrier according to the invention is then equipped with the impregnating composition by impregnation or impregnation. Excess impregnation is removed, for example, by squeezing to the desired moisture content. The equipped carrier is then packed airtight and stored at 20 ° C for two months. After the storage period has ended, the impregnation solution is pressed out of the carrier and its pH is determined. This pH must be in the range from 2.5 to 6.0, preferably in the pH range from 3.5 to 5.5, and particularly preferably in the pH range from 4.0 to 5.0.

The amount of the suitable buffer system depends on the one hand on the individual constituents of the cosmetic impregnation composition and on the other hand on the acidic or basic character of the carrier material which may be present. It has been shown that the substances acting as buffers within the range of 0.1-10% by weight, preferably 1.0-5.0% by weight and particularly preferably 1.0-4.0% by weight. %, based in each case on the amount of active substance weighed in by the corresponding acid-base pair, per weight of the impregnation composition. The material for the flexible carrier according to the invention, which is in cloth or pad form, is selected from woven and non-woven nonwovens made of cotton fibers, plastic and mixed fibers. The nonwoven nonwovens are preferred. Suitable fiber materials are, for example, polypropylene, polyester and viscose. The wipes can be single, two or three layers. Wipes with more than three layers are also suitable according to the invention. The nonwoven can be hydroentangled. Furthermore, the nonwoven fabric can have a structure and / or a pattern and / or holes.

The synthetic rubbers are selected, for example, from styrene-butadiene rubber, isoprene rubber, polybutadiene, butyl rubber, ethylene-propylene rubber, silicone rubber, polyurethane rubber, ethylene-vinyl acetate rubber, polynorbornene rubber and acrylic rubber. Particularly preferred synthetic rubbers are styrene-butadiene rubber, isoprene rubber and polybutadiene.

In a further preferred embodiment, the sponges according to the invention consist of polyurethane foam rubber. They can be produced by the direct reaction of diisocyanates and polyols in a reaction-casting fuel process and subsequent impregnation or impregnation with the cosmetic composition. The foam rubber sponges can be cut or punched in any shape that is optimally adapted to the respective application.

The flexible carrier according to the invention can be equipped with the aqueous impregnating composition by spraying or by impregnation. After equipping, the excess liquid can be removed by squeezing.

The flexible carriers according to the invention can be in moist form and can be delivered to the end user. Moistening before use is therefore not necessary. Such flexible carriers are convenient and time-saving to use and particularly suitable for on the go. A product is usually supplied as a moist carrier which, in the case of a sponge, contains about 0.1-0.4 g of soaking solution per cm ^{3 of} the dry sponge. In the case of cloths and fleeces, this is Weight ratio of the non-finished cloth to the impregnation composition 1: 1 to 1: 5.

It is also possible to dry the flexible carriers equipped with the aqueous impregnation composition to a water content of at most 15% by weight, preferably at most 10% by weight and particularly preferably at most 7% by weight. These dried carriers can be moistened with water before use and then used to treat the skin, hair or nails.
