Product description

AakoEmu PCP MB is better known as Potassium Cetyl Phosphate. It is the most effective oil-in-water anionic (EO-free) O/W emulsifier for UV-filters and emollients. Has a good stability with a broad variety of oil blends and UV-filters. It even helps to boost the Sun Protection Factor (SPF) of UV filters. Potassium Cetyl Phosphate is especially suitable for the manufacturing of stable water-resistant sunscreen formulations with a good spread-ability and pleasant skin feel.

Potassium Cetyl Phosphate is easy to handle as it is soluble in hot water. Easier to use than Polyacrylic Acid in emulsion manufacturing, without dispersion, wetting problems or fish eyes in solution. Comes in a neutralized form what means it is ready to use and it gives fast, predictable viscosity. This product is pre-neutralised to the potassium salt, what is important in order to rapidly and reproducibly obtain the desired viscosity of your emulsion.


  • Free of halogenated compounds.
  • Great spread-ability and pleasant skin feeling.
