Science & Benefits

This advanced, branched silicone polymer is a high-efficiency emulsifier specifically designed for 'water-in-silicone' (W/Si) formulations. It is prized for its ability to stabilize large amounts of water within a very light silicone matrix, resulting in products that feel watery and cooling upon contact. Because of its unique branched structure, it creates a flexible, breathable moisture net on the skin surface. It is entirely non-comedogenic and serves as a sophisticated humectant vehicle, ensuring that water is delivered deep into the stratum corneum without any of the greasiness or follicular obstruction associated with traditional oil-in-water creams.
