Composition for treating dandruff in hair and scalp based on an antidandruff agent and an acrylic terpolymer

摘要

Anti-dandruff composition contains an acrylic terpolymer comprising 1-6C alkyl (meth)acrylate monomer, heterocyclic vinyl containing a nitrogen or sulfur atom(s), (meth)acrylamide, mono- or di-1-4C alkylamino-1-4C alkyl (meth)acrylate or mono- or di-1-4C alkylamino-1-4C alkyl (meth)acrylamide and monomer from urethane. Anti-dandruff composition comprises a cosmetic medium, an acrylic terpolymer comprising: (a) 5-80 (15-70, especially 40-70) wt.% 1-6C alkyl (meth)acrylate monomer; (b) 5-80 (10-70, especially 20-60) wt.% heterocyclic vinyl containing a nitrogen or sulfur atom(s), (meth)acrylamide, mono- or di-1-4C alkylamino-1-4C alkyl (meth)acrylate or mono- or di-1-4C alkylamino-1-4C alkyl (meth)acrylamide; and (c) 0.1-30 (0.1-10) wt.% monomer from urethane produced by reacting a monoethylenically unsaturated isocyanate and a nonionic surfactant including a 1,2-butylene oxide/ethylene oxide block copolymer with terminal 1-4C alkoxy, an ethylenically unsaturated surfactant monomer obtained by condensing a nonionic surfactant and an alpha , beta -unsaturated carboxylic acid (anhydride), a (meth)allyl ether of formula (III), and a urethane nonionic monomer produced by reacting a monohydric nonionic surfactant with a monoethylenically unsaturated isocyanate; and anti-dandruff agent(s) from: (1) benzethonium chloride, benzalkonium chloride, chlorhexidine, chloramine T, chloramine B, 1,3-dibromo-5,5-dimethylhydantoin, 1,3-dichloro-5,5-dimethylhydantoin, 3-bromo-1-chloro-5,5-dimethylhydantoin and N-chlorosuccinimide; (2) 1-hydroxy-2-pyridone of formula (I); (3) trihalocarbamides of formula (II); (4) triclosan ; (5) N compounds such as climbazole, ketoconazole, clortrinazole, econazole, isoconazole or miconazole; (6) antifungal polymers such as amphotricine B or nystatine; (7) selenium sulfides; and/or (8) sulfur, cadmium sulfate, allantoin, oil or wood tar, undecylenic acid, fumaric acid or allylamine. CH2CR1CH2OAmBnApR2 (III) R1 = H or CH3; A = propyleneoxy or butylenoxy; B = ethyleneoxy; n = 0-200; m, p = 0 or number smaller than n; R2 = at least 8C hydrophobic group; R3 = 1-17C alkyl, 2-17C alkenyl, 5-8C cycloalkyl, 7-9C bicycloalkyl, cycloalkyl(alkyl), aryl, aryl-1-4C alkyl, aryl-2-4C alkenyl, aryloxy-1-4C alkyl, arylmercapto-1-4C alkyl, furyl-2-4C alkenyl, 1-4C alkoxy, NO2, CN or halogen; R4 = H, 1-4C alkyl, 2-4C alkenyl, halogen, phenyl or benzyl; X = organic base or alkali(ne earth) metal; and Z = halogen or trihalo-1-4C alkyl. An Independent claim is also included for a process for treating wet or dry hair by applying the composition, then after a period of time rinsing with water.
