Use Of Polymers Of N-vinyl Caprolactam

- Nov 16, 2019-

For hair cosmetics, the use of gel formulations is increasing. The hair styling composition in the gel preparation and the gel preparation should satisfy the following technical conditions, namely, non-toxic, transparent, colorless, non-sticky, good styling effect, low hygroscopicity, and good consistency. .


The copolymers used herein also exhibit certain properties that require improvement. Most gels are turbid to opaque except for certain nonionic copolymers such as Luviskol K90, K30, Luviskol VA 64 (BASF) or polyvinylformamide. The hair treated with these copolymers is also highly absorbent and highly viscous. The stereotype effect also needs to be improved.


The hair cosmetic preparations include, in particular, a setting agent and/or a conditioning agent in a hair cosmetic preparation, such as a hair treatment agent, a hair mousse, a (hair) gel or a hair spray, a hair lotion, a conditioner, and a wash. Hair, hair lotion, hair fluid, long-acting hair coloring agent, hair coloring agent and bleaching agent, "hot oil" preparation, conditioning agent, hair fixative or hair spray. Depending on the field of application, hair cosmetic preparations can be applied in the form of (aerosol) sprays, (aerosol) foams, gels, gel sprays, ointments, lotions or waxes.


Suitable hair cosmetic polymers are also neutral polymers such as polyvinylpyrrolidone, copolymers of N-vinylpyrrolidone and vinyl acetate and/or vinyl propionate, polysiloxanes, polyvinyl caprolactam. And copolymers containing N-vinylpyrrolidone, polyethyleneimine and salts thereof, polyvinylamine and salts thereof, cellulose derivatives, polyaspartates and derivatives.


To produce certain properties, the formulation may additionally comprise a conditioning material based on a silicone compound. Suitable silicone compounds are, for example, polyalkylsiloxanes, polyarylsiloxanes, polyarylalkylsiloxanes, polyethersiloxanes, silicone resins or polydimethylsiloxane copolymers. Alcohol (CTFA) and amino-functional polysiloxane compounds such as amino-terminated polydimethylsiloxane (CTFA).


The polymers of N-vinylcaprolactam we offer are particularly suitable for use in hair styling formulations, especially hair sprays (aerosol sprays and pump sprays without propellant gas) and hair mousses (aerogels and Used as a setting agent in pumping mousse without propellant gas.
