RESIN SOLUTION CONTAINING AMINE OXIDE GROUP AND RESIN COMPOSITION FOR HAIR COSMETIC MATERIAL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a resin solution containing an amine oxide group that is free from a problem of coloring or discoloring with the lapse of time and a resin composition for a hair cosmetic material using it. SOLUTION: The resin solution containing an amine oxide group contains a resin containing the amine oxide group. The resin composition for a hair cosmetic material is prepared using the resin solution containing an amine oxide group. A sample solution prepared from the resin solution containing an amine oxide group consists of 18% by weight of the resin containing an amine oxide group, 10% by weight of water and 72% by weight of ethanol. The sample solution has the difference value (da) between an (a) value (a0) in the Lab color system and the maximum (a) value (amax) among (a) values after the sample solution is irradiated with UV-rays of 5 or less and the difference value (db) between a (b) value (b0) of the sample solution and the (b) value (bm) when the sample solution has the amaxof 9 or less.
