Pearlescent Agent: Under specific conditions, it can contribute to pearlescent effects.

Base for Cleansing Balms/Solid Cleansers: Acts as a solid oil phase, giving the product its melting property.

Product Applications: Face creams, lotions, hand creams, body butters, foundations, lipsticks, soaps, shampoos, conditioners, etc.
