Kerazyne™ MB by INOLEX is a novel quat-free polymeric conditioning additive for hair care. It is a polyesteramine with the emolliency and gloss characteristic of an ester, and the cationic activity of an amine. It is highly hydrophobic and lubricious. Kerazyne™ MB provides more intensive conditioning than standard conditioning additives such as polyquaternium polymers and amodimethicone. It reduces static charge, improves feel and improves combability.
