Cosmetic preparations with Guerbet alcohols

The present invention relates to cosmetic preparations with Guerbet alcohols and cationic emulsifiers, preferably combinations of Guerbet alcohols and Dimethyldioctadecylammoniumchlorid.

The desire to look beautiful and attractive is inherently rooted in man. Although the ideal of beauty has undergone changes over time, the pursuit of an impeccable appearance has always been the goal of man. An essential part of a beautiful and attractive appearance is the condition and appearance of the skin.

For the skin to fulfill its biological functions to the full extent, it needs regular cleaning and care. Cleansing of the skin serves to remove dirt, sweat and remnants of dead skin particles, which form an ideal breeding ground for pathogens and parasites of all kinds. Skin care products are usually used to moisten and restore the skin. Often, agents that regenerate the skin and, for example, prevent and reduce their premature aging (e.g., wrinkles, wrinkles) are added to them.

Skin care products usually consist of emulsions. Emulsions are generally understood to mean heterogeneous systems which consist of two liquids which are immiscible or only to a limited extent miscible with one another, which are usually referred to as phases and in which one of the two liquids is dispersed in the form of very fine droplets in the other liquid. Viewed externally and with the naked eye, emulsions appear homogeneous.

If the two liquids are water and oil and oil droplets are finely distributed in water, then it is an oil-in-water emulsion (O / W emulsion, eg milk). The basic character of an O / W emulsion is characterized by the water. A water-in-oil emulsion (W / O emulsion, eg butter) is the reverse principle, whereby the basic character is determined by the oil. In order to keep emulsions stable over a longer period of time and to prevent segregation of the phases, so-called emulsifiers are added to the emulsions. Emulsifiers are usually molecules with a polar, hydrophilic structural element and a nonpolar, lipophilic structural element. In the late 1940s, a system was developed to facilitate the selection of emulsifiers. Each emulsifier is assigned a so-called HLB value (a dimensionless number between 0 and 20) which indicates whether there is a preferred water or oil solubility. Numbers below 9 indicate oil-soluble, hydrophobic emulsifiers, numbers above 1 1 water-soluble, hydrophilic.

Emulsifiers can be present in different forms, for example as anionic emulsifiers (for example: potassium cetyl phosphate), as nonionic emulsifiers (for example: polyoxyethylene (4) cetyl ether) or as cationic emulsifiers (for example dimethyldioctadecylammonium chloride).

Cationic emulsifiers, in particular dimethyldioctadecylammonium chloride (INCI: Distearyldimonium Chloride, CAS 0764-2), when used in cosmetic preparations, lead to aqueous formulas which rapidly enter the skin and produce a dull skin sensation. Because of these properties, the preparations are difficult to distribute on the skin.

It was therefore the object of the present invention to develop a cosmetic preparation based on an emulsion formed with the emulsifier dimethyldioctadecylammonium chloride, which produces a less dull skin feel and at the same proportion of oil and water phase to a less aqueous and easily distributed on the skin Preparation leads.

Another object of the present invention was to develop a cosmetic preparation based on an emulsion formed with the emulsifier dimethyldioctadecylammonium chloride, which has a higher viscosity at the same proportion of oil and water phase.

A further object of the present invention was to develop a cosmetic preparation based on an emulsion formed with the emulsifier dimethyldioctadecylammonium chloride, in which anionic cosmetic ingredients or anionic active ingredients, in particular anionic polymeric thickeners, can be stably incorporated without causing, for example, lumps or Precipitation comes. Cosmetic emulsions regularly contain greater amounts of glycerin than skin moisturizers. A disadvantage of such preparations, however, is the fact that the glycerol in the formulas regularly leads to the preparation feeling sticky on the skin.

Another object of the present invention was therefore to develop a cosmetic emulsion with the emulsifier dimethyldioctadecylammonium chloride and glycerol, which is significantly less sticky than comparable preparations of the prior art.

Surprisingly, the objects are achieved by a cosmetic preparation comprising a combination of a) Guerbet alcohols and b) one or more cationic emulsifiers.
