SODIUM SILICOALUMINATE.

Insufficient Data CAS 1344-00-9 / ABRASIVE, BULKING, VISCOSITY CONTROLLING

Sodium Silicoaluminate serves as a multi-functional ingredient, primarily acting as a physical abrasive for surface cleansing and an effective agent for modifying product texture. It functions as a bulking and viscosity controlling agent, optimizing cosmetic formulations, and may offer a mattifying effect on the skin.

Summary

Abrasive Bulking Viscosity Controlling Mattifying Oil Absorbing

Science

Mechanism of Action

Operating as an abrasive, Sodium Silicoaluminate physically removes surface impurities through a gentle grinding or polishing action. In formulations, it acts as a bulking agent, decreasing product density through swelling, and as a viscosity controlling agent, allowing for precise adjustment of product consistency. Its intrinsic hygroscopic properties suggest a potential for absorbing excess oil and contributing to a mattified skin appearance.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically evaluated Sodium Silicoaluminate, although related silicates have been reviewed. The U.S. FDA recognizes it as generally safe (GRAS) for anticaking in food at concentrations up to 2%. However, assessments regarding skin irritation present conflicting data; some sources indicate no irritation, while others report it as a potential irritant to skin, eyes, and mucous membranes.

Verdict

Insufficient Data

While functionally useful in formulations and potentially beneficial for oily skin, its lack of dedicated clinical efficacy and safety data for skin, coupled with conflicting irritation reports, warrants further investigation for precision skincare applications.
