Abstract

A block copolymer for hair styling compositions includes hydrophilic and hydrophobic blocks which allow for optimization of desirable characteristics of the hair styling composition, such as style retention at high humidity, tack, hardness, resistance to flaking, and washability from the hair. The copolymer includes a polyacrylate backbone of hydrophobic blocks, with hydrophilic acrylate side chains. The copolymer is suitable for the formulation of a number personal care, household, hair care, skin care and other formulation. The copolymer is suited to incorporation into low VOC hydra-alcoholic hair styling compositions to meet reduced VOC regulations.

Description

Background of the invention

[0001] The present invention relates to novel polymers containing branched / block copolymer structures for the treatment of keratinous substrates, and in particular to cosmetic compositions incorporating such polymers, such as hairsprays, hair conditioners, hair styling lotions, styling creams and the like. The polymers provide cosmetic compositions with higher hold, less flakiness and better styling than conventional polymers used in hair and similar cosmetic preparations.

[0002] Natural and synthetic polymers, usually incorporated into aqueous or aqueous / alcoholic solutions, are currently used as pomades, hair styling lotions, and the like. The function of this polymer is to give the hair "shape" and hold.

[0003] Currently, the main polymers or polymers used in hairsprays, styling lotions and hair conditioners include polyvinylpyrrolidone (PVP) homopolymers and copolymers, half esters of polyvinyl ether-maleic anhydride, polyvinyl acetate - C...
