Safety Information
Overview
Ingredient Profile
Role of Perlite
Active Cosmetic Mechanisms
ABSORBENT
Moisture & Oil AbsorberSoaks up excess moisture, oil, or other liquids from skin surfaces
SCIENTIFIC ANALYSIS
// Evidence: Absorbent materials possess high porosity and surface area that enable them to take up and retain liquids, sebum, perspiration through capillary action and adsorption. Common absorbents include kaolin clay, talc, silica, cornstarch. These ingredients can absorb multiple times their weight in moisture. The absorption mechanism can be physical (porous structure) or chemical (hygroscopic properties).
BULKING
Volume BuilderAdds volume and body without adding weight
SCIENTIFIC ANALYSIS
// Evidence: Bulking agents increase product volume while maintaining low density. These include low-density powders (hollow microspheres, perlite, expanded polymers), aerogels, and materials with high specific volume. Mechanism involves entrapping air within particle structures or creating open, porous networks. In hair products, bulking agents coat individual strands, increasing diameter and creating space between hairs.
