Description

[0001] The application describes hair treatment products based on a combination of specific linear alkanes as well as cationic and cationizable conditioning agents, a method for hair treatment with these products, and the use of these products for the care of keratin fibers.

[0002] Human hair is exposed to a number of stresses, particularly cosmetic ones, in addition to natural environmental influences. These stresses include, for example, hair coloring and hair shaping, such as through a perm. Cosmetic hair care products are used to reduce the adverse effects of these (environmental) influences on hair structure, as well as to maintain and improve the natural hair structure. A key active ingredient in many of these cosmetic products are organosilicon compounds, especially silicones such as trisiloxanes, which are characterized by their conditioning properties. The disadvantages of these silicones are that, due to their coating of the hair surface, the penetration of active ingredients and excipients into the hair is reduced, and the coating also makes styling more difficult.Furthermore, for sustainability reasons, efforts are being made to use the highest possible proportion of biodegradable active ingredients in cosmetic products. Providing low-silicone or silicone-free care products is therefore a relevant task in the field of hair cosmetics.

[0003] Linear paraffins have been discussed in the prior art as one of numerous classes of active ingredients suitable for substituting silicones. For example, patent application WO 2010 / 115973A1 (Biosynthis) describes cosmetic compositions containing mixtures of linear C8-C 12 -Alkanes and C 14 -C 24These products contain alkanes in addition to other ingredients. However, these compositions still have a number of disadvantages, and despite the progress made so far, there remains a need for low-silicone or silicone-free hair care products based on volatile so-called "light emollients." Documents DE 102013226539A1 and DE 102011087974A1 disclose hair care compositions that contain silicone block polymers or isopraffins as conditioning agents in their respective conditioning mixtures.

[0004] It has now been established that by combining specific linear alkanes with specific cationic and cationizable conditioning agents, hair care products with excellent conditioning effects can be obtained.

[0005] These viscosity- and storage-stable products give the treated hair good shine, improved grip, and excellent detangling and combability.

[0006] The first subject matter of this application is a hair treatment product containing - based on its weight - a) 0.1 to 20 wt.% of at least one linear alkane selected from C9-, C 10 -, C 11 - and C 12 -Alkanes and mixtures of these alkanes comprising at least 50% dodecane, b) 0.1 to 20 wt.% of at least one linear alkane selected from C 15 -, C 16 -, C 17 -, C 18 -, C 19 -, C 20 -, C 21 -, C 22 - and C 23 -Alkanes and mixtures of these alkanes, comprising at least 50% docosane, c) 0.1 to 20 wt% of at least one amidoamine and / or one cationized amidoamine, and d) 0.1 to 20 wt% of at least one cationic surfactant selected from (i) Esterquats and / or (ii) quaternary ammonium compounds, wherein the linear alkanes a) and b) are present in the hair treatment product in a weight ratio a) : b) in the range of 40 : 60 to 60 : 40.
