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 WO suncare systems SPF 30 (theoretical) were formulated with mineral UV filters and the respective emulsifier at the suggested concentrations. The spectrophotometric determination of static SPF (Fig. 1) reveals that OLEAMULS® WO provides SPF boosting properties ensuring the adequate protection.
A sunscreen product is labelled “water resistant” (WR) if the effectiveness of its SPF, following 2 immersions in water, each 20 minutes in length, is greater than 50% of its initial SPF. SESAMULS® WO outperforms the benchmark in maintaing water resistance getting very close to the maximum level (Fig. 2).
