Description

The present invention relates to hair treatment compositions, in particular shampoos. Shampoos are used to cleanse and care for the hair. The care is achieved through the use of so-called care substances. These are cationically charged hydrophilic polymers that attach to the negatively charged keratin fibers by ionic interaction and improve their combability. In addition, hydrophobic substances such as silicones can be used. These also serve to care for the hair. The care performance and the sensors on the hair during and after the application are highly dependent on the structure of the care substances, as well as the blend. Although this results in excellent care performance, it is often associated with a negative effect on the sensory profile due to the high polymer use concentration, especially during the rinsing process. The hair feels weighed after applying the shampoo.

The font WO 2008049701 A1 discloses hair treatment compositions containing a particular copolymer, at least one silicone, at least one conditioner, which apparently can be chosen at random from a very, very variable group of substances and groups of substances. The font WO 2008092933 A1 discloses a composition comprising a polymer a) having cationic and / or cationogenic groups and a molecular weight Mw in the range of 10,000 to 5 million and a further more specific polymer WO 2004043414 A1 discloses a hair washing composition having from 1 to 50% of cleaning surfactants, 0.01 to 0.5% of cationic surfactant of a certain charge density, 0.01 to 0.4% of further cationic surfactant of certain charge density and water, and oil drops.

The font EP 1366742 A1 discloses a guar hydroxypropyltrimethylammonium chloride cosmetic formulation of the class of galactomannan 2-hydroxypropyltrimethylammonium chloride ethers having an average molecular weight of 600,000 to 2,000,000 and a charge density of 0.4 to 1.0 meq / g, another polymer of quaternized ammonium salt of hydroxypropylcellulose substituted with trimethylammonium Epoxy is modified and surfactants and optionally other cosmetic active ingredients, excipients and additives. The font EP 1366738 A1 discloses a preparation with a copolymer of vinylpyrrolidone and vinylimidazole having a cationic charge density of less than or equal to 2 meq / g, guar hydroxypropyltrimethylammonium chloride and surfactants besides optionally other cosmetic active substances, auxiliaries and additives.

It has surprisingly been found that a hair shampoo containing an ampholytic polymer (A) having the general structural formula {- [CH ₂ -CHR ⁸ ] _p - [CH ₂ -CR ⁹ R ⁷ ] _o } _k - where R ^{9 is} the group R ¹ R ² R ³ N ⁺ - [CH ₂ ] _m -CHR ⁴ - [CH ₂ ] _n -R ⁵ R ⁶ N ⁺ -CH ₂ -NH- (C = O) - and
R ¹ , R ² , R ³ , R ⁵ , R ⁶ and R ^{7 are} independently H, CH ₃ and / or C ₂ H ₅ , R ^{4 is} H, CH ₃ , C ₂ H ₅ or OH, R ^{8 is} COOH , COO-CH ₃ or NH ₂ and m, n, o, p are integers and satisfy the following conditions: 1 ≤ m ≤ 2; 1 ≤ n ≤ 4; 1 ≤ o ≤ 2; 1 ≤ p ≤ 4, a cationic hydrophilic copolymer (B) of vinylpyrrolidone, vinylimidazil and diallyldimethylammonium chloride, an anionic surfactant (C), particularly preferably in its active content concentrations of 5 to 15 wt.%, Preferably 6 to 10 wt.% remedies the disadvantages of the prior art. This preparation has a superior care performance without negative influence of sensory properties compared to standard formulations.

A preparation according to the invention shows a superior care performance without negative influence on the sensor system: INCI 1 2 Aqua 83.4 83.8 Sodium Laureth Sulfate 10 10 Cocamidopropyl betaines 3 3 Polyquaternium-74 0.3 Polyquaternium-87 0.5 Polyquaternium-10 0.3 Guar hydroxypropyltrimonium chlorides 0.1 Sodium benzoate 0.4 0.4 Sodium Salicylate 0.4 0.4 PEG-3 distearate 1.5 1.5 Perfume 0.5 0.5 Table 1

Formula 1: preparation according to the invention; Formula 2: Reference

The use of a preparation according to the invention leads to a superior care performance in comparison to the reference product. The product according to the invention was evaluated as non-oily during rinsing against a medium oil appearance during rinsing in the case of the reference product. The product according to the invention was rated as much better than the reference product in terms of the entangleability and combability of wet hair. This was rated by trained panelists, also called experts. 10 g 2 hrs of bleached hair tresses were used. The hair strand was soaked for at least 15 minutes and then combed with the coarse comb segment and then with the fine comb segment, wet under running water and once streaked with light pressure. A syringe was drawn up with 2 ml of product and the contents of the syringe applied to the strand of hair. The product was foamed from top to bottom for 60 seconds and then rinsed out. During the rinsing process, the parameters "oily" and after rinsing with the large segment of a comb the "disentanglement" and then with the fine segment of the comb the "combability" are evaluated.

It is preferred if the ampholytic copolymer (B) is present in concentrations of 0.1 to 1% by weight, preferably 0.3 to 0.5% by weight. It is further preferred if polyquaternium-74 is used as the ampholytic polymer (A). It is particularly preferred if polyquaternium-87 is used as the cationic hydrophilic copolymer (B). It is particularly preferred if a cationic hydrophilic care polymer is present in concentrations of 0.1 to 1% by weight, preferably 0.3 to 0.5% by weight. In this case, it is particularly preferred if the mass-related concentration ratio of ampholytic copolymer to cationic hydrophilic care polymer is from 1: 2 to 2: 1, more preferably from 4: 5 to 5: 4. It is particularly preferred if hydroxypropyltrimonium chlorides, polyquaternium-10 or polyquaternium-7 are present or absent in a concentration of at most 0.5% by weight. It is most preferred if in addition a zwitterionic surfactant in concentrations of 0.3 to 5 wt.%, Preferably 0.5 to 1.5 wt.%, Based on its active content, is included. It is very particularly preferred if the content of PQ-10 is 0 to 0.3% by weight. It is very particularly preferred if the content of PQ-7 is 0 to 0.3% by weight.
