Title:
弾性カチオン性ポリウレタン
Document Type and Number:
Japanese Patent JP4275941
Kind Code:
B2
Abstract:
The invention concerns novel cationic polyurethanes with elastic character, that is having immediate recovery ranging between 5% and 95%, consisting essentially (a1) of cationic units derived from at least a tertiary amine having at least two functions reactive to labile hydrogen, said tertiary amine being at least partly neutralised, (a2) non-ionic units derived from non-ionic polymer s bearing at their ends functions reactive to labile hydrogen and having a glass transition temperature (Tg), measured by differential heat content analysis, less than 10° C., optionally (a3) non-ionic units derived from non-ionic monomer compounds containing at least two functions reactive to labile hydrogen, and (b) units derived from at least a diisocyanate, and cosmetic compositions containing said polymers.
