film forming block copolymer, hair styling and shampoo compositions, and processes for preparing a hair styling composition, for enhancing the streaking of a hair styling composition, for increasing the volume of hair, to increase the diameter of the hair and to improve the ability to style the hair again.

摘要

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.
