Branched block copolymer for treatment of keratinous substrates

摘要

A kind of block copolymer for hair styling composition includes the optimized hydrophilic and hydrophobic block for allowing the required characteristic of hair styling composition, such as it flow on hair, the prevention of curl droop, retain in the big pattern of humidity, drawing pin, hardness, resistance to flaking, restylability increases, the washability from hair. Copolymer includes a polyacrylate backbone of hydrophobic block, with hydrophilic acrylate's side chain. Copolymer is applicable to the preparation of a number personal nursing, family, hair nursing, skin nursing and other preparations. Copolymer is suitable for being incorporated to the alcoholic hair styling composition of low VOC water the management to meet reduced VOC.
