Kerazyne™ MB

Polyester-11

Multi-Functional Conditioning Polymer

Kerazyne™ MB is a multi-functional conditioning polymer for cleansers, scalp care, and conditioning formulas with a desirable sustainability profile compared to other conditioners. This Polyesteramine has a unique mechanism to associate with different surfactant systems without impacting cleansing effectiveness or inhibiting foam.

  • Enhances formula mildness and decreases irritation from surfactants
  • Alternative for polyquaternium and amodimethicone chemistries
  • Reduces static charge in hair care
  • Provides micellar thickening
  • Formulator-friendly pourable liquid form for cold processing and clear formulas

Applications:
hair conditioner | hair treatments | hair styling | skincare | body care | cleansing

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.
