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.
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).
