BRB 1018 is a 60% anionic emulsion of a high molecular weight polydimethylsiloxane. A very good additive for 2-in-1 products. In 2-in-1 shampoos, it improves the wet combing and imparts a soft feel to the hair as well as improving shine. Suggested for rinse-off products. Great for those products looking for straightening claims.
