Definitions
- the present invention relates to crosslinked polyurethanes based on polytetrahydrofurans and their use in cosmetic and / or pharmaceutical preparations.
- hair treatment agents which are present, for example, as hair setting agents or hair spray, are used for setting, improving the structure and shaping the hair.
- the hair treatment compositions consist primarily of a solution of film-forming resins or synthetic polymers. So far, the following film formers have mainly been used in hair treatment agents: shellac, homopolymers and copolymers of N-vinylpyrrolidone, copolymers of vinyl ethers / maleic acid half-esters, of (eth) acrylic acid or its esters and amides and crotonic acid with vinyl esters.
- the hair treatment agents are sprayed onto the hair in the form of solutions, preferably as ethanolic solutions. After the solvent has evaporated, the hair is held in the desired shape by the remaining polymer at the points of mutual contact.
- the polymers should be so hydrophilic that they can be washed out of the hair, on the other hand, they should be hydrophobic so that the hair treated with the polymers maintain their shape even at high atmospheric humidity and do not stick together.
- the previously known polymeric film formers such as polyvinylpyrrolidones
- polyvinylpyrrolidones mostly have the disadvantage of excessive water absorption with increased atmospheric humidity. This property leads, among other things, to undesired sticking of the hair and to a loss of strength and therefore a breakdown of the hairstyle.
- the resistance to high air humidity is improved, for example in the case of copolymers of N-vinylpyrrolidone and vinyl acetate, the production effect of the film suffers and can even lead to unpleasant dusting and a flaky coating.
- the washability when cleaning the hair is made more difficult.
- the present invention has for its object to provide auxiliaries for cosmetic and pharmaceutical preparations.
