COSMETIC COMPOSITION COMPRISING FUNCTIONALISED POLY(ALPHA OLEFIN-COPOLYMER- MALEIC ANHYDRIDE) |
摘要 |
<p>A cosmetic composition is described comprising functionalised polyanhydrides, specifically functionalised poly(alphaolefin-copolymer-maleic anhydride) copolymers, thereafter also indicated as functionalised polyanhydrides. It is further described a process to prepare such a cosmetic composition by the functionalisation of the polyanhydrides by opening reactions of the anhydride ring with molecules containing at least one OH or NH2 group.</p> |
