N-Vinyl caprolactam CAS 2235-00-9
N-Vinylcaprolactam; 1-Ethenylazepan-2-one; 1-Vinylhexahydro-2H-azepin-2-one; 1-Ethenylhexahydro-2H-azepin-2-one; NVCL
For hair cosmetics, the use of gel formulations is increasing. The hair styling composition in such gel preparation and the gel preparation should satisfy the following technical conditions, namely, non-toxic, transparent, colorless, non-sticky, good styling effect,not too hygroscopic, and have good consistency .
Cosmetic formulation for hair cosmetic applications, comprising a copolymer of China N-Vinyl Caprolactam and N-vinyl heterocyclic compounds.
The prior art of N-Vinyl Caprolactam factory contains copolymers of N-vinyllactams such as Luviskol K, Luviskol VA Luviquat Hold or Luviskol Plus(BASF) for use in cosmetic formulations, especially for hair cosmetic formulations, It is especially useful as a hair styling composition.
The copolymers used herein also show certain properties that need improvement. Except for certain non-ionic copolymers, such as Luviskol K90, K30, Luviskol VA 64(BASF) or polyvinyl formamide, most gels are cloudy to opaque. The ease of water absorption and stickiness of hair treated with these copolymers is also high. The styling effect also needs improvement.
N-Vinyl Caprolactam CAS 2235-00-9 manufacturers have now found that N-containing monomers that can be cationized, preferably at a content of not more than 5% by weight, preferably 2-4% by weight, can especially produce transparent gels with good setting effects Glue. Surprisingly, it has now been found that small amounts of monomer C can lead to a significant improvement in performance.
DE-C 12 61 822 describes copolymers of N-vinylcaprolactam with,for example, N-vinylimidazole and N-vinylpyrrolidone.The copolymer is used as a reagent for reducing pigment migration during the process of dyeing a fiber material with a pigmentary dyeing solution.
