Cold processable wo emulsifier for water in oil emulsions

INCI name

Polyglyceryl-6 Pentaoleate, Sesamum Indicum (Sesame) Seed Oil, Malic Acid



SESAMULS® WO is a water in oil emulsifier obtained from renewable sources through the esterifcation of polyglycerin-6 to olive oil fatty acids whereas the natural Malic Acid acts as a catalyst.

It allows rich emulsions with a nourishing feel. Easy to use, also in cold processing, and well-tolerated by the skin, it is remarkably versatile in terms of formulation and compatibility with all active ingredients

SESAMULS® WO is ideal in sun care products for mineral filters dispersion and improves makeup products shine.


OLEAMULS® WO is a nonionic Water in Oil emulsifying system obtained from renewable sources: Italian olive oil and Polyglycerol from vegetable glycerin.

Easy to use, also in cold processing, it is remarkably versatile in terms of formulation and compatibility with all active ingredients and well-tolerated by the skin.

Water in oil emulsions allow deeply moisturizing, rich and nourishing formulations containing as low as 30- 35% of natural oils as the sole source of lipids achieving a unique sensoriality uncommon in water in oil systems.

Bar charts comparing static SPF values and water resistance between Sesamuls WO, Oleamuls WO, and a benchmark.
  • 100% plant-derived raw materials.
  • Ideal for nourishing emulsions for sensitive and dry skins manufactured via cold processing technique in alternative to the Water in Oil (WO) PEG emulsifier.
  • It stabilizes emulsion viscosity even in presence of lipid phases with different polarities. Does not require co-emulsifiers.
  • Compatible under extreme anionic and cationic conditions across a wide range of pH values (pH 3-9).
  • It facilitates the dispersion of any sort of powder, from titanium dioxide to iron oxides, and it functions as a shine enhancer that improves the shine of make-up products.
  • Emulsions are easily absorbed and, despite being rich in natural lipids, neither greasy nor sticky.
  • Soluble in ethanol, mineral and vegetal oils, fatty acids, fatty alcohols and their derivatives.
