Potassium Cetyl Phosphate

What is Potassium Cetyl Phosphate?

Potassium Cetyl Phosphate is a mild anionic emulsifier derived from fatty alcohols and phosphate esters. It’s valued for its stability, skin compatibility, and ability to support elegant O/W emulsions, even with challenging actives like UV filters or exfoliants. It’s commonly used in modern, PEG-free emulsifier systems.

Why Use Potassium Cetyl Phosphate?

• Mild & Non-Irritating: Suitable for daily-use and sensitive formulas
• SPF-Friendly: Helps emulsify and stabilize sunscreens with UV filters
• Excellent Stability: High electrolyte and pH tolerance
• PEG-Free: Ideal for natural and clean-label formulations
• Supports Active Delivery: Works well in AHA/BHA and vitamin-based systems

Performance Highlights

• Compatible with a broad range of esters, oils, and silicones
• Produces light, silky, and fast-absorbing emulsions
• Enhances emulsion stability even at low concentrations

Additional Application Examples:

• SPF 30–50 sunscreen formulations
• Anti-aging and antioxidant face creams
• Daily-use moisturizers for oily/combination skin
• Vitamin C or retinol cream emulsions

Formulation Tip:

Heat in the oil phase (70–75°C). Can be used alone or with co-emulsifiers like glyceryl stearate or cetearyl alcohol for enhanced stability and richness.
