Application of Bentonite
Bentonite is a general purpose additive that is used as a pigment and colorant and to clarify and stabilize wine.
filler in cosmetics and other products, gel, or solid if dry.As of Fuller's earth; as emulsifier for oils; as a base for plasters. Pharmaceutic aid (suspending agent).Bentonite (bentonite clay) is used to regulate the viscosity and suspension properties of a cosmetic formulation. It also acts as an overall formula stabilizer. Bentonite’s water-absorption capabilities allow it to form a gelatinous mass. Considered a noncomedogenic raw material, bentonite is a colloidal aluminum silicate clay.
