Guanidine Carbonate Based Hair Relaxer (Formulation #C5002) 


Croda 禾大

Guanidine Carbonate Based Hair Relaxer (Formulation #C5002) is a formulation that features products supplied by Croda. As a nonionic emulsifying wax Polawax™ NF is an ideal inert base for the delivery actives and is chemically stable at extremes of pH. In this formulation Polawax™ makes an elegant stable cream base which, on mixing with the activator (in a ratio of 4:1), causes the release of free guanidine to relax the hair.

Secondary emulsifiers Volpo N10 and Crodacol™ C90 aid emulsion stability. The aggressiveness of the hair relaxer is controlled by including varying levels of mineral oil and white petroleum jelly.
