Description

The invention relates to hair treatment compositions which contain cationic care substance (s) and certain viscosity regulants as well as the use of these agents for the cleaning and / or care of hair.

The cosmetic treatment of skin and hair is an important part of human body care. For example, 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 dyes, tinting agents, waving agents and styling preparations. In this case, means for changing or nuancing the color of the head hair play a prominent role.

Consumers expect a cosmetic product to deliver consistent product performance under all conditions of use. In surfactant cleaning formulations such as shampoos, shower gels, bath foams, etc., however, the viscosity is highly dependent on temperature, with the viscosity usually decreases with increasing temperature. As a result, a corresponding product is perceived by the consumer in the summer as "too thin" in winter as too viscous. In addition, the consumer expects identical product characteristics regardless of their location and the prevailing climatic conditions there.

The in temperature ranges, the normal application temperatures of o. G. Means correspond, stable viscosity adjustment succeeds with certain polymers. However, the use of these polymers limits the freedom from formulation, since most viscosity regulators are sensitive to the electrolyte concentration of the agents and to their pH. Stable thickened formulations can therefore only be produced in the neutral pH range.

These agents in turn have the disadvantage that they can be protected for preservation against attack by microorganisms only with those preservatives that are considered critical by some consumers and are undesirable, for example because they split off formaldehyde.

Another problem is the incorporation of cationic care substances with it. These are highly desirable due to their exceptional care effects, but can not be combined with many conventional thickeners.

Hair treatment agents can also be provided in the form of hair lotions or leave-on products and often contain lower alcohols - these in turn are incompatible with most thickeners.

It was therefore an object to provide hair treatment compositions which are viscosity-stable even when cationic care agents and alcohols in wide temperature ranges.

It has now been found that the combination of cationic care substances and alcohols with certain polymers overcomes the disadvantages mentioned.

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 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. In the context of the invention, water-insoluble are to be understood as meaning those UV filters which dissolve in water at 20 ° C. to not more than 1% by weight, in particular not more than 0.1% by weight. 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.

• – substituierte Benzophenone,
• – p-Aminobenzoesäureester,
• – Diphenylacrylsäureester,
• – Zimtsäureester,
• – Salicylsäureester,
• – Benzimidazole und
• – o-Aminobenzoesäureester.

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 derive are, for example

• Substituted benzophenones,
• P-aminobenzoic acid ester,
• - diphenylacrylic acid ester,
• - cinnamic acid ester,
• Salicylic acid ester,
• Benzimidazoles and
• O-aminobenzoic acid ester.

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 selected 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 selected so 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 are C _{1 -4} alkyl groups, R ³ is a C _1-22 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 represents} either 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 trimethyl ammonium chloride (Incroquat ^® UV-283) and Dodecyldimethylaminobenzamidopropyl-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 especially 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 substance 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.

The short-chain carboxylic acids according to the invention may have one, two, three or more carboxy groups. Preferred within the meaning of the invention are carboxylic acids having a plurality of carboxy groups, in particular di- and tricarboxylic acids. The carboxy groups can be used, in whole or in part, as ester, acid anhydride, lactone, amide, imidic acid, lactam, lactim, dicarboximide, carbohydrazide, hydrazone, hydroxam, hydroxime, Amidine, amidoxime, nitrile, phosphonic or phosphate esters are present.

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

• Addition products of from 4 to 30 mol of ethylene oxide and / or from 0 to 5 mol of propylene oxide onto linear fatty alcohols having from 8 to 22 carbon atoms, to fatty acids containing from 12 to 22 carbon atoms and to alkylphenols having from 8 to 15 carbon atoms in the alkyl group,

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.

The compositions according to the invention may preferably contain at least one nonionic emulsifier having an HLB value of 8 to 18. Nonionic emulsifiers with an HLB value of 10-15 may be particularly preferred according to the invention.

As further advantageous, it has been shown that, in addition to any polymer (s) from the group of cationic polymers optionally contained as a care substance, further polymers (G) are contained in the agents according to the invention. In a preferred embodiment, therefore, further polymers are added to the compositions according to the invention, both anionic and nonionic polymers having proven effective.

The anionic polymers (G2) are anionic polymers which have carboxylate and / or sulfonate groups. Examples of anionic monomers from which such polymers may consist are acrylic acid, methacrylic acid, crotonic acid, maleic anhydride and 2-acrylamido-2-methylpropanesulfonic acid. The acidic groups may be wholly or partly present as sodium, potassium, ammonium, mono- or triethanolammonium salt. Preferred monomers are 2-acrylamido-2-methylpropanesulfonic acid and acrylic acid.

Anionic polymers which contain 2-acrylamido-2-methylpropanesulfonic acid as the sole or co-monomer can be found to be particularly effective, it being possible for all or some of the sulfonic acid group to be present as sodium, potassium, ammonium, mono- or triethanolammonium salt ,

More preferably, the homopolymer of 2-acrylamido-2-methyl propane sulfonic acid, which is available for example under the name Rheothik ^® 11-80 is commercially.
