FIELD: chemistry.

SUBSTANCE: present invention relates to a comb-shaped copolymer comprising: (A) one or more repeating units obtained from olefinically unsaturated cationic or cation-active comonomers; and (B) one or more repeating units of formula where Y is a moiety which forms part of the copolymer backbone and is obtained from a monomer selected from at least one of the following monomers: olefinically unsaturated cationic or cation-active comonomers, acrylamide monomers, one or more olefinically unsaturated hydrophilic monomers, one or more olefinically unsaturated monomers; Z is a moiety capable of forming an associate with another moiety Z or other moieties in the preparation in which the copolymer will be used, and is a hydrophobic moiety selected from alkyl, aryl, aralkyl, fluoroalkyl groups having 8-50 carbon atoms, an organosilicon group having 35-25 linked SiO moieties, and silane; and b is a bond or a moiety, linking the moiety Z with a moiety Y, and represents covalent bonds formed by at least one ester, carbonyl, amide, amine oxide, hydrocarbon, amino, ether, polyoxyalkylene groups, or a bond resulting from ionic salt bonds. The invention also describes a personal hygiene product and a composition for the personal hygiene product containing said comb-shaped copolymer.

EFFECT: obtaining a comb-shaped cationic copolymer, which provides a balance of the required properties when used in personal hygiene products and other cosmetic preparations in terms of the sensory perception thereof and the degree of deposition or retention of active ingredients.
