AMMONIUM PALM KERNEL SULFATE.

Optional CAS 223705-48-4 / CLEANSING, FOAMING, SURFACTANT - CLEANSING

Ammonium Palm Kernel Sulfate is an anionic surfactant derived from palm kernel oil, primarily used as a cleansing and foaming agent. It helps reduce surface tension for effective product distribution and debris removal in rinse-off applications.

Summary

surfactant cleansing foaming

Science

Mechanism of Action

It reduces water's surface tension, aiding in the emulsification of oils and debris for removal. The sulfate group can ionically interact with positively charged keratin on skin and hair, enhancing cleansing efficacy.
