Kerazyne™ MB is a novel polymeric conditioning additive for hair care. It reduces static charge, improves feel, and improves combability. It is a polyesteramine and has emolliency and gloss characteristics of an ester, and the cationic activity of an amine. It has novel esthetics that are unlike the feel of any polymeric conditioning agent. It is highly hydrophobic and lubricious and provides much more intensive conditioning than standard conditioning additives such as polyquaternium polymers and amodimethicone. Kerazyne MB product forms include cream conditioners and cream styling products(emulsions), as well as anhydrous products.
