Science
Mechanism of Action
This ingredient increases the apparent volume of cosmetic products by swelling, consequently reducing their density. It plays a crucial role in enhancing the tactile texture and smooth application of creams, lotions, and powders. Additionally, it forms a thin, protective film on the skin, which allows for vapor exchange.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deems this ingredient generally safe for topical application in cosmetic products. Their assessments of related silicate compounds (e.g., aluminum silicate) and inorganic hydroxides (e.g., magnesium hydroxide) also confirm safety when formulated to prevent irritation. While typically well-tolerated, a small subset of individuals may experience transient skin irritation, redness, or itching, suggesting the utility of preliminary patch testing. Independent evaluations from EWG assign a 'low' rating for cancer, allergies, and immunotoxicity concerns, with a 'low_moderate' rating for developmental and reproductive toxicity. INCI Beauty corroborates its favorable safety profile with a 'No penalty' rating.
