EMPICOL OP 301 is an aqueous solution of styrene/acrylate copolymer. This product can be used to impart a milky or translucent appearance to liquid detergents and cosmetics at typical addition levels of 0.1 - 1.0%. The very low level of residual monomer ensures that this product does not interfere with any of the perfumes used. To ensure maximum compatibility it should be pre-diluted with water, at least 1:4, and added slowly with stirring as the last addition. EMPICOL OP 301 contains nonionic (alcohol ethoxylate) and anionic (sodium alkyl sulfate) surfactants that comply with the biodegradability criteria of the EC directive on Detergents 648 / 2004 / EC.
