Hydroxyamide-functionalized polysiloxane emulsion preparation, for use in cosmetics such as shampoos, by reacting organopolysiloxane and lactone in presence of emulsifier and aqueous phase

摘要

Preparation of emulsions of hydroxyamide-functionalized polysiloxanes (I) containing N-hydroxyacylaminated unit(s) involves reacting an organopolysiloxane (II) containing aminated unit(s) with a lactone (III) in presence of an emulsifier and an aqueous phase. Preparation of emulsions of hydroxyamide-functionalized polysiloxanes (I) containing unit(s) of formula TaRbSiO(4-a-b)/2 (a) involves reacting an organopolysiloxane (II) containing unit(s) of formula QaRbSiO(4-a-b)/2 (b) with a lactone of formula (III) in presence of an emulsifier and an aqueous phase. T = -R1-(NR2(CH2)c)d-NR3CO-(CR42)e-(CR5OH)f-CR62-OH; Q = -R1-(NR2(CH2)c)d-NR3-H; R = 1-18C hydrocarbyl (optionally substituted by F, Cl and/or Br), H, 1-12C alkoxy, OH or alkyl glycol residue; R1 = 1-18C hydrocarbylene; R2, R3 = H or 1-18C hydrocarbyl (optionally substituted by F, Cl and/or Br); R4 - R6 = H or 1-18C hydrocarbyl (optionally substituted by OH, F, Cl and/or Br); a = 1-3; b = 0-2; c = 0-6; d, e = 0-4; f = 1-6.
