High Monoester Cetyl Phosphate | Mass Balance RSPO

Cola®Fax CPE MB is an oil-soluble long chain organic phosphate ester supplied as a free acid in powdered form. It is generally used as a co-emulsifier with low HLB nonionics, and is non-irritating to skin. Cola®Fax CPE MB is easily dissolved into either phase during emulsion processing and can be neutralized in-situ with various cations. Cola®Fax CPE MB, at low use concentrations, will enhance the stability of emulsions and thicken cremes and lotions. It can replace TEA-stearate in most preparations. Cola®Fax CPE MB is ideally suited for use in many dermatological and personal care products.

  • Emulsion stabilizer – overcomes imbalances in HLB emulsifier values for various oil systems.
  • Easy to formulate. Acid form is oil soluble; neutralized salts are water-soluble. Can be substituted for polyacrylic acid type polymers, which are frequently utilized as emulsion stabilizers without increasing viscosity to an unacceptable limit.
  • Physically easier to use than polyacrylic acid. No dispersion, wetting problems or fish eyes in solution.
  • Good rub out and afterfeel. Does not inhibit quick break emulsion properties.
  • Primary emulsifier, providing excellent performance at normal skin pH.
  • Easy-to-handle, without noxious dust particles.
  • Readily biodegradable per OECD 301 methods


  • Sunscreens
  • Low viscosity emulsions
  • Lotions
  • Cleansing milks
