Description

"Hair cleanser with plant extracts"

The present invention relates to hair treatment compositions containing plants extra kte.

Human hair is today treated in a variety of ways with hair cosmetic preparations. These include, for example, the cleansing of hair with shampoos, the care and regeneration with rinses and cures, and the bleaching, dyeing and shaping of the hair with colorants, tinting agents, waving agents and styling preparations.

Not least by the heavy use of hair, for example by dyeing or perming as well as by the hair with shampoos and by environmental pollution, the importance of care products with the longest possible effect increases. Such care products affect the natural structure and properties of the hair. Thus, for example, after such treatments, the wet and dry combability of the hair, the hold and the fullness of the hair can be optimized or the hair can be protected from increased splitting.

It has therefore long been customary to subject the hair to a special aftertreatment. In this case, the hair is treated with special active ingredients, for example quaternary ammonium salts or special polymers, usually in the form of a rinse. Depending on the formulation, this treatment improves the combability, the hold and the fullness of the hair and reduces the splitting rate.

Furthermore, so-called combination preparations have recently been developed to reduce the burden of the usual multi-stage process, especially in the direct application by consumers.

The available active ingredients both for separate aftertreatment agents and for combination preparations generally have a preferential effect on the hair surface. Thus, active ingredients are known which give the hair shine, hold, fullness, better wet or dry combabilities or prevent splitting. Just as important as the external appearance of the hair, however, is the internal structural cohesion of the hair fibers, which can be greatly influenced, in particular, by oxidative and reductive processes such as dyeing and perming.

However, the known active ingredients can not cover all needs sufficiently.

Particularly in the case of hair cleansing, an increased awareness of hygiene leads to an ever more frequent cleaning of the hair. In addition to optimal cleaning and care of the hair To be suitable for long-term use, the funds used must be particularly mild to the hair and scalp. Although mild surfactants from a wide variety of groups are known per se, these do not yet sufficiently satisfy all consumer wishes.

For example, it has been shown that frequent hair washing can affect the structure of the keratin fibers, requiring the addition of certain substances that enhance the internal structure of the keratin fibers, thereby improving the strength, feel and tensile strength of keratin fibers.

There is therefore a need for active ingredients or combinations of active ingredients for hair cleansing compositions which not only do not impair the structure of the fibers treated with them but on the contrary improve them.

It is an object of the present invention to provide hair cleansing compositions which impart advantageous properties in terms of strength, feel and tensile strength as well as combability in the dry and wet state to the hair treated with them and are particularly mild.

It is known to use plants extra kte in cosmetic products to give the products a specific property profile. It has now been found that the effect of plant extracts in general and of certain plant extracts in particular can be increased by a special formulation of the products by formulating the products PEG-free.

In a first embodiment, the present application relates to hair cleansing compositions containing, in a cosmetically acceptable carrier, based on its weight,

(a) 0.1 to 35% by weight of at least one surfactant,

(b) from 0.1 to 10% by weight of at least one plant extract, characterized in that it contains no compounds of the formula (I)

H- (O-CH ₂ CH ₂ ) _n -OH (I),

in which n stands for integers between 1 and 100,000.

The hair cleansing compositions according to the invention are free of polyethylene glycols of the general formula (I), ie they contain neither ethylene glycol (n = 1) nor products with a degree of polymerisation P _n = 2-4 (diethylene glycol, triethylene glycol and tetraethylene glycol) Polyethylene glycols with higher degrees of polymerization P _n of about 5 to 100,000, not more mol. -uniform, but polydisperse.

Surprisingly, the omission of compounds of the formula (I) leads to the plant extracts having a significantly better effect on the hair. In particular, the strengthening of the keratinic fibers, which manifests itself in improved combing in the dry and especially in the wet state, and the fullness and smoothness are improved.

Preferably, the agents according to the invention are not only free of polyethylene glycols but also of polypropylene glycols (PPG). Hair cleansing agents preferred according to the invention are characterized in that they do not contain any compounds of the formula (I))

H- (O-CH (CH ₃ ) CH ₂ ) _n -OH (II),

in which n stands for integers between 1 and 100,000.

Such preferred hair cleansing compositions according to the invention are free of polypropylene glycols of general formula (II), ie they contain neither propylene glycol (n = 1) nor products with a degree of polymerisation P _n = 2-4 (dipropylene glycol, tripropylene glycol and tetrapropylene glycol) or polypropylene glycols with higher degrees of polymerization P _n from about 5 to 100,000, which are no longer molar-uniform producible, but polydisperse.

These compounds also hinder the development of the effect of the plant extracts on the hair, so that the improved effects can be observed by dispensing with their use.

It has been found that preferably should be dispensed with the use of ethoxylated compounds. In particular, nonionic surfactants of the alkyl or alkenyl ethoxylate type also reduce the positive effects of the plant extracts and should therefore not be used in the formulations. According to further preferred hair cleansing compositions are therefore characterized in that they are not compounds of formula (INI)

R- (O-CH ₂ CH ₂ ) _n -OH (III),

wherein R represents any alkyl or alkenyl radical and n represents integers between 1 and 10,000.

Ethoxylated anionic surfactants can also - albeit to a lesser extent - reduce the positive effects of plant extracts. Here are in particular alkyl ether sulfates as while alkyl ether carboxylates show less effect-reducing effects than the ether sulfates.

Preferred hair cleaners according to the invention therefore contain no compounds of the formula (IV)

R- (O-CH ₂ CH ₂ ) _n -OSO ₃ H (IV),

where R is any alky or alkenyl radical and n is an integer between 1 and 10,000.

In particularly preferred inventive agents is completely dispensed with the use of compounds having ethoxylated groups. Interestingly, a hydroxyethyl moiety (eg, in certain surfactants) does not affect the action of the plant extracts, while ethylene glycol affects the effect. Preferred hair cleaners according to the invention therefore contain no compound which contains the grouping - (O-CH ₂ CH ₂ ) _n -O- with n = 1-10,000. Particularly preferred hair cleansing compositions according to the invention are characterized in that they contain no compounds which contain the grouping of the formula (V)

- (O-CH ₂ CH ₂ ) _n - (V),

in which n stands for integers between 2 and 100,000.

The compositions according to the invention contain from 0.1 to 35% by weight of at least one surfactant. As already mentioned above, ethoxylated nonionic surfactants are preferably eliminated; anionic surfactants from the groups of the alkyl ether sulfates are also preferably not used. Particularly preferred is the use of amphoteric and / or zwitterionic surfactants.

Zwitterionic surfactants and emulsifiers are those surface-active compounds which carry in the molecule at least one quaternary ammonium group and at least one - COO ⁽⁾ - or -SO ₃ ⁽⁾ group. Particularly suitable zwitterionic surfactants and emulsifiers are the so-called betaines, such as N-alkyl-N, N-dimethylammonium glycinates, for example cocoalkyldimethylammonium glycinate, N-acylaminopropyl-N, N-dimethylammonium glycinates, for example cocoacylaminopropyldimethylammonium glycinate, and 2-alkyl-3 carboxymethyl-3-hydroxyethyl-imidazolines each having 8 to 18 carbon atoms in the alkyl or acyl group, and the cocoacylaminoethylhydroxyethylcarboxymethylglycinate. A preferred zwitterionic surfactant is the fatty acid amide derivative known by the INCI name Cocamidopropyl Betaine. Ampholytic surfactants and emulsifiers are understood as meaning those surface-active compounds which, apart from a C ₈ -C ₂₄ -alkyl or -acyl group, contain at least one free amino group and at least one -COOH or -SO ₃ H group and are capable of forming internal salts , Examples of suitable ampholytic surfactants are N-alkylglycines, N-alkylaminopropionic acids, N-alkylaminobutyric acids, N-alkyliminodipropionic acids, N-hydroxyethyl-N-alkylamidopropylglycines, N-alkyltaurines, N-alkylsarcosines, 2-alkylaminopropionic acids and alkylaminoacetic acids each having about 8 to 24 C atoms in the alkyl group.

In addition to the surfactant (s), the agents according to the invention contain at least one plant extract. An extract in the sense of the present application is a substance or substance mixture which has been obtained by extraction and partial or complete evaporation of the extraction solution. A distinction is made according to the nature dry extracts. Extracts evaporated to dryness, fluid extracts i. extracts prepared with solvents such that at most 2 parts of fluid extract are recovered from one part of the drug, viscous extracts or thick extracts, i. Extracts in which part of the solvent is evaporated.

The plant extracts used according to the invention are obtained from plants or plant parts by extraction, preferably with organic solvents, water or mixtures thereof. Preferred organic solvents are ketones (eg acetone), ethers, esters, alcohols or halogenated hydrocarbons. Particularly preferred extractants are water and / or alcohols. Among the alcohols, (C ₁ to C ₆ ) alcohols, such as ethanol and isopropanol, both as the sole extractant and in admixture with water, are preferred.

The extraction is preferably carried out at a temperature of 25 ° C to 90 ⁰ C.

Usually these extracts are produced by extraction of the whole plant. However, in individual cases it may also be preferred to prepare the extracts exclusively from flowers and / or leaves of the plant. With regard to the plant extracts which can be used according to the invention, particular reference is made to the extracts listed in the table beginning on page 44 of the 3rd edition of the guideline for the ingredient declaration of cosmetic products, published by the Industrieverband Körperpflege- und Waschmittel eV (IKW), Frankfurt.

Pomegranate extracts are particularly preferred according to the invention, since they significantly improve the combability, in particular the wet combability, of keratinic fibers and give the fibers more fullness and volume. The pomegranate or the grenadine (Punica granatum) is a plant that is now attributed to the family of the Weiderichgewächse (Lythraceae). The genus consists of two species only the subfamily Punicoideae (Horan.) SAGRAHAM, Thorne & Reveal. The home of the pomegranate is located in Western to Central Asia; today it is cultivated among other things in the Mediterranean area.

Extracts of pomegranate are mainly from the fruits, partly from whole fruits, partly from pure pulp, partly from pre-washed seeds, partly from the shell, won. All of these extracts are suitable according to the invention; for reasons of cost, extracts from the whole fruit are preferred since upstream separation and preparation steps are eliminated. Even pomegranate-pressed pomegranate oil is inventively used as pomegranate extract. The extracts are rich in pomegranate polyphenols such. As of punicalagin, ellagitannine or ellagic acid.

Another extract which can be used according to the invention with particular preference is Roibos extract, also called Rotbusch extract. Rooibos (Aspalathus linearis) is a plant of South Africa belonging to the legume family (Fabaceae).

Extracts of Roibos are made from the branches of the plant. The harvest of the redbush branches takes place in the growth phase of growth of the bush from summer to early autumn. As in the case of tea bushes, the extracts of roibos from unfermented branches (avoiding fermentation by gentle handling of the harvested branches of redbush, the branches are simply dried, cleaned by sieving and pasteurized with steam) or fermented branches (here the branches and branches) Branch particles are cut, squeezed and moistened with water, favored by the warm climate in the producer country, which is then left to an 8-24-hour fermentation) to be produced. Roibos extracts preferred according to the invention are produced from unfermented Roibos.

Another extract which can be used according to the invention with particular preference is almond extract. The almond tree (Prunus dulcis, Syn: Prunus amygdalus), belongs to the family Rosaceae.

Another extract that can be used with particular preference according to the invention is elderflower extract. The elderberries (Sambucus) form a genus in the family of the musk plants (Adoxaceae). The genus contains about 20 to 30 species worldwide, three of which are native to Central Europe. The best known of these three species is the Black Elder, which is shortened in today's usage usually referred to as "Elderberry" becomes. In addition, there is also shrubby red elder and the perennial or dwarf Zwunder Holunder. The species grow in temperate to subtropical climates and in higher elevations of tropical mountains.

The berry-like drupes contain one to five seeds and can be black, blue or red.

Elderberry extracts can be made from the flowers, fruits or seeds of the fruits.

Of course, mixtures of o.g. Silicones may be included in the compositions of the invention.

Preferred according to the invention can be used silicones have viscosities at 20 ⁰ C for from 0.2 to 2 mmV ^1, wherein silicones having viscosities of 0.5 to 1 mmV ¹ are particularly preferred.

The silicones are preferably water-soluble. Agents preferred according to the invention are characterized in that they contain at least one water-soluble silicone.

For aesthetic reasons, "clear" products are often preferred by consumers, hair treatment agents which are preferred according to the invention are therefore characterized in that they are transparent or translucent.

In the context of the present invention, transparent or translucent is understood as meaning a composition which has an NTU value of less than 100. The NTU value (Nephelometrie Turbidity Unit, NTU) is a unit used in water treatment for turbidity measurements in liquids. It is the unit of turbidity measured with a calibrated nephelometer.

Furthermore, in a preferred embodiment of the invention, an agent according to the invention may also contain UV filters (I). The UV filters to be used according to the invention are not subject to any general restrictions with regard to their structure and their physical properties. Rather, all UV filters which can be used in the cosmetics sector and whose absorption maximum is in the UVA (315-400 nm), in the UVB (280-315 nm) or in the UVC (<280 nm), are suitable. Area is located. UV filters with an absorption maximum in the UVB range, in particular in the range from about 280 to about 300 nm, are particularly preferred.

The UV filters used according to the invention can be selected, for example, from substituted benzophenones, p-aminobenzoic acid esters, diphenylacrylic acid esters, cinnamic acid esters, salicylic acid esters, benzimidazoles and o-aminobenzoic acid esters.

Examples of UV filters which can be used according to the invention can be found in the priority application for this application - DE 10 2008 016 218.3 - on pages 37/38.

Preference is given to those UV filters whose molar extinction coefficient at the absorption maximum is above 15,000, in particular above 20,000.

Furthermore, it has been found that in structurally similar UV filters in many cases, the water-insoluble compound in the teaching of the invention has the higher effect compared to such water-soluble compounds that differ from it by one or more additional ionic groups. For the purposes of the invention, water-insoluble UV filters are those which dissolve in water at not more than 1% by weight, in particular not more than 0.1% by weight, at 20 ^° C. Furthermore, these compounds should be soluble in the usual cosmetic oil components at room temperature to at least 0.1, in particular at least 1 wt .-%). The use of water-insoluble UV filters may therefore be preferred according to the invention.

According to a further embodiment of the invention, preference is given to those UV filters which have a cationic group, in particular a quaternary ammonium group.

These UV filters have the general structure U - Q.

The structural part U stands for a UV-absorbing group. This group can in principle be derived from the known UV filters which can be used in the cosmetics sector, in which a group, generally a hydrogen atom, of the UV filter is replaced by a cationic group Q, in particular having a quaternary amino function , Compounds from which the structural part U can be derived are, for example, substituted benzophenones, p-aminobenzoic acid esters,

diphenylacrylic,

cinnamic,

salicylic acid,

Benzimidazoles and o-aminobenzoic acid esters. Structural parts U which are derived from cinnamic acid amide or from N, N-dimethylaminobenzoic acid amide are preferred according to the invention.

The structural parts U can in principle be chosen such that the absorption maximum of the UV filters can be in both the UVA (315-400 nm) and in the UVB (280-315 nm) or in the UVC (<280 nm) range. UV filters with an absorption maximum in the UVB range, in particular in the range from about 280 to about 300 nm, are particularly preferred.

Furthermore, the structural part U, also as a function of structural part Q, is preferably chosen such that the molar extinction coefficient of the UV filter at the absorption maximum is above 15,000, in particular above 20,000.

The structural part Q preferably contains, as a cationic group, a quaternary ammonium group. This quaternary ammonium group can in principle be connected directly to the structural part U, so that the structural part U represents one of the four substituents of the positively charged nitrogen atom. Preferably, however, one of the four substituents on the positively charged nitrogen atom is a group, especially an alkylene group of 2 to 6 carbon atoms, which functions as a compound between the structural portion U and the positively charged nitrogen atom.

Advantageously, the group Q has the general structure - (CH ₂ ) _X -N ⁺ R ¹ R ² R ³ X ^' , in which x is an integer from 1 to 4, R ¹ and R ² independently of one another

R ³ is a C 1-4 alkyl group or a benzyl group and X ^"is a physiologically acceptable anion In the context of this general structure, x preferably represents the number 3, R ¹ and R ² each represent a methyl group and R ³ either represents a methyl group or a saturated or unsaturated, linear or branched hydrocarbon chain having 8 to 22, in particular 10 to 18, carbon atoms.

Physiologically acceptable anions are, for example, inorganic anions such as halides, in particular chloride, bromide and fluoride, sulfate ions and phosphate ions and organic anions such as lactate, citrate, acetate, tartrate, methosulfate and tosylate.

Two preferred UV filters with cationic groups are the commercially available compounds cinnamic acid-trimethylammonium chloride (lncroquat ^® UV-283) and dodecyl tosylate (Escalol ^® HP 610).

Of course, the teaching of the invention also includes the use of a combination of several UV filters. In the context of this embodiment, the combination of at least one water-insoluble UV filter with at least one UV filter with a cationic group is preferred. The UV filters (I) are usually contained in the agents according to the invention in amounts of 0.1-5% by weight, based on the total agent. Levels of 0.4-2.5 wt .-% are preferred.

The compositions of the invention may further contain a 2-pyrrolidinone-5-carboxylic acid and its derivatives (J). Preference is given to the sodium, potassium, calcium, magnesium or ammonium salts in which the ammonium ion carries, in addition to hydrogen, one to three C ₁ - to C ₄ -alkyl groups. The sodium salt is most preferred. The amounts used in the compositions according to the invention are preferably from 0.05 to 10% by weight, based on the total composition, particularly preferably from 0.1 to 5, and in particular from 0.1 to 3,% by weight.

In addition, it may prove advantageous if the compositions according to the invention contain penetration aids and / or swelling agents (M). These include, for example, urea and urea derivatives, guanidine and its derivatives, arginine and its derivatives, water glass, imidazole and its derivatives, histidine and its derivatives, benzyl alcohol, glycerol, glycol and glycol ethers, propylene glycol and propylene glycol ethers, for example propylene glycol monoethyl ether, carbonates, bicarbonates, Diols and triols, and in particular 1, 2-diols and 1, 3-diols such as 1, 2-propanediol, 1, 2-pentanediol, 1, 2-hexanediol, 1, 2-dodecanediol, 1, 3-propanediol, 1 , 6-hexanediol, 1, 5-pentanediol, 1, 4-butanediol.

Advantageously in the context of the invention, short-chain carboxylic acids (N) may additionally support the active ingredient complex (A). Short-chain carboxylic acids and their derivatives in the context of the invention are understood to mean carboxylic acids which may be saturated or unsaturated and / or straight-chain or branched or cyclic and / or aromatic and / or heterocyclic and have a molecular weight of less than 750. For the purposes of the invention, preference may be given to saturated or unsaturated straight-chain or branched carboxylic acids having a chain length of from 1 to 16 C atoms in the chain, very particular preference being given to those having a chain length of from 1 to 12 C atoms in the chain.

In a further preferred embodiment, the agents according to the invention may contain emulsifiers (F). Emulsifiers effect at the phase interface the formation of water- or oil-stable adsorption layers, which protect the dispersed droplets against coalescence and thus stabilize the emulsion. Emulsifiers are therefore constructed like surfactants from a hydrophobic and a hydrophilic part of the molecule. Hydrophilic emulsifiers preferably form O / W emulsions and hydrophobic emulsifiers preferably form W / O emulsions. An emulsion is to be understood as meaning a droplet-like distribution (dispersion) of a liquid in another liquid under the expense of energy in order to create stabilizing phase interfaces by means of surfactants. The selection of these emulsifying surfactants or emulsifiers depends on the substances to be dispersed and the respective outer phase and the fineness of the emulsion. Emulsifiers which can be used according to the invention are, for example

Examples of zoosterols are cholesterol and lanosterol. Examples of suitable phytosterols are ergosterol, stigmasterol and sitosterol. Mushrooms and yeasts are also used to isolate sterols, the so-called mycosterols.
