OLEAMULS® WO
Cold-processable W/O emulsifier for rich yet elegant textures
INCI
Polyglyceryl-6 Pentaoleate
COLD PROCESSABLE
ELEGANT TEXTURE
SPF ENHANCER
OLEAMULS® WO is a non-ionic W/O emulsifying system obtained from upcycled olive oil by-products 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.
Allows the creation of rich yet elegant emulsions with a less greasy skin feel compared to traditional W/O systems.
EFFICACY TESTS
OLEAMULS® WO IN SUNCARE APPLICATION
Three water-in-oil (WO) suncare systems with theoretical SPF 30 were formulated using mineral UV filters and the respective emulsifier at recommended concentrations. Spectrophotometric analysis of static SPF (Fig. 1) shows that OLEAMULS® WO enhances SPF, ensuring adequate protection.
A sunscreen is labeled “water resistant” (WR) if its SPF effectiveness remains above 50% of the initial SPF after two 20-minute water immersions. SESAMULS® WO outperforms the benchmark in maintaining water resistance, approaching the maximum level (Fig. 2).
