Potassium Cetyl Phosphate

Potassium Cetyl Phosphate is an anionic emulsifying ingredient used in cosmetic and personal care formulations to help combine oil and water into stable, uniform emulsions.

Particularly useful in creams, lotions, and sunscreen formulations, it helps improve emulsion stability while supporting lightweight, smooth, and elegant product textures. It can be used alongside compatible co-emulsifiers and fatty alcohols to develop a range of formulation consistencies.

Key Benefits

• Effective Emulsification: Helps combine oil and water phases in oil-in-water (O/W) formulations.

• Emulsion Stability: Supports uniformity and helps reduce the risk of phase separation.

• Texture Enhancement: Contributes to smooth, pleasant application characteristics.

• Formulation Versatility: Suitable for lightweight lotions as well as richer creams.

• Sunscreen Compatibility: Commonly used in sunscreen emulsion systems, subject to formulation testing.

Applications

• Facial creams and moisturizers

• Body lotions

• Sunscreen lotions and creams

• Daily skincare emulsions

• After-sun products

• Cosmetic emulsions requiring an anionic emulsifier
