Treatment composition antidandruff the hair and scalp, a base of a salt of pyridinethione, of one conditioning agent which is insoluble and an acrylic terpolymer
An antidandruff composition (A), comprises pyridine thione salt and an insoluble conditioner, an acrylic terpolymer (I) derived from: (a) 1-6C alkyl (meth)acrylate; (b) a vinyl heterocyclic compound, (meth)acrylamide or mono- or dialkylaminoalkyl (meth)acrylate or (meth)acrylamide; and (c) one of a wide range of further monomers, such as surface-active esters, ureas or urethanes. An antidandruff composition (A), comprises cosmetic medium containing at least one pyridine thione salt (PTS) and at least one insoluble conditioning agent (CA). Additionally comprises at least one acrylic terpolymer (I) comprising: (a) 5-80 (preferably 15-70, especially 40-70) wt. % units derived from a 1-6C alkyl (meth)acrylate; (b) 5-80 (preferably 10-70, especially 40-70) wt. % units derived from a vinyl heterocyclic compound (containing at least one O or S), a (meth)acrylamide, a mono- or di-(1-4C alkyl)-amino-(1-4C) alkyl (meth)acrylate or a mono- or di-(1-4C alkyl)-amino-(1-4C) alkyl (meth)acrylamide; and (c) 0.1-30 (preferably 0.1-10) wt. % units derived from: (i) a urethane obtained by reacting a mono-ethylenically unsaturated isocyanate with a 1-4C alkoxy-terminated nonionic surfactant, (ii) a 1,2-butylene oxide/ethylene oxide block copolymer, (iii) a surface-active ethylenically unsaturated comonomer obtained by condensing a nonionic surfactant with an alpha , beta -ethylenically unsaturated carboxylic acid or its anhydride, (iv) a urea-type surface active monomer obtained by reacting a mono-ethylenically unsaturated monoisocyanate with a nonionic surfactant having an amine function, or (v) a (meth)allyl ether of formula CH=C(R1)CH2-O-AmBnApR2 (II) or (vi) a urethane-type nonionic monomer obtained by reacting a monohydric nonionic surfactant with a monoethylenically unsaturated isocyanate. R1 = H or Me; A = propyleneoxy or butyleneoxy group; B = ethyleneoxy; n = 0-200; m, p = 0 or integer less than n; R2 = hydrophobic group of at least 8C.
