AMMONIUM SULFITE.

Optional CAS 10196-04-0 / HAIR WAVING OR STRAIGHTENING, PRESERVATIVE, REDUCING

A dual-function ingredient that serves as both a preservative and antioxidant in cosmetic formulations. Primarily utilized in hair care products for its reducing properties, it also protects skincare formulations from microbial contamination and oxidative degradation. Its highly charged molecular structure limits skin penetration, making it suitable for topical applications.

Summary

preservative antioxidant reducing agent

Science

Mechanism of Action

Functions as a reducing agent by donating hydrogen atoms to neutralize oxidative processes and inhibit microbial growth. Any absorbed sulfite is rapidly metabolized to harmless sulfate through the body's natural sulfite oxidase enzyme pathway, ensuring efficient clearance from skin tissues.
