Science

Mechanism of Action

This ingredient functions by visibly tightening the skin through its astringent action, concurrently maintaining skin health as a conditioning agent, and safeguarding it from external factors. While the precise molecular mechanism specific to SODIUM ZINC CETYL PHOSPHATE requires further elucidation, its zinc ion component is recognized for its redox-inert nature. Zinc ions play critical catalytic and structural roles in various proteins, influencing cellular regulation, transport, and signaling pathways. Furthermore, zinc is known to stimulate numerous enzymatic activities and is integral to immune system function.

Stability

Although specific pH stability data for SODIUM ZINC CETYL PHOSPHATE is not explicitly available, related cetyl phosphate ingredients, such as Cetyl Phosphate, typically exhibit stability in the pH 6-7 range (3% aqueous solution), while Potassium Cetyl Phosphate is stable between pH 6.5-8.5. This ingredient functions effectively as an anionic oil-in-water emulsifier and co-emulsifier, thereby enhancing emulsion stability and increasing the viscosity of creams and lotions. It demonstrates broad compatibility with various oils and emollients, frequently incorporated into stable, water-resistant formulations, particularly sunscreens. It is critical to note that zinc speciation is highly pH-dependent, which may influence formulation considerations.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has assessed numerous inorganic and organometallic zinc salts, including Zinc Phosphate, concluding their safety in cosmetics when formulated to be non-irritating. SODIUM ZINC CETYL PHOSPHATE is also approved and subject to specific restrictions under Annex III of the EC Cosmetics Regulation, following evaluation by the Scientific Committee on Consumer Safety (SCCS). These restrictions may encompass purity criteria, maximum concentration limits, or specific product categories. While a precise maximum concentration for SODIUM ZINC CETYL PHOSPHATE is not explicitly stated in general safety assessments, related cetyl phosphate compounds are considered safe for use at low concentrations. Its safe use is contingent upon adherence to these regulatory conditions and proper formulation practices.
