The Science Behind
Kerazyne™ MB a polyesteramine.
This chemistry provides hair conditioning through multiple mechanisms:
- Non-quat cationic sites are attracted to anionically charged hair fibers
- Ester linkages provide secondary attractive forces to hair fibers
- Alkyl group provides a protective, conditioning layer once bound to hair
The combined effects result in emolliency and gloss characteristic of an ester and adhesion properties comparable to traditional amines.
In cleansing applications, polyesteramines interact with surfactant molecules and reduce the interaction of individual surfactant molecules with the skin's lipid bilayers. The result is a reduction in skin irritation during cleansing.
