What are the benefits of a water-in-oil emulsion system?

Silicone-based water-in-silicone and water-in-oil (W/O) emulsifiers have existed since the mid-1980s, and a broad range of these materials is now available. W/O systems provide benefits such as wash-off resistance, substantivity, improved barrier properties, emolliency, moisturization and, in some cases, can influence the penetration of actives.
Silicone-based emulsifiers can impart the same benefits without most of the drawbacks associated with water-in-oil systems, such as greasy feel, difficult and costly manufacturing and less formulation flexibility when compared to oil-in-water systems . Silicone emulsifiers also provide broader options for oil phase, expanded texture and sensory possibilities.
DOWSIL™ ES-5600 Silicone Glycerol Emulsifier: a versatile PEG-free emulsifier for fluid inverse emulsion
Dow Corning® ES-5600 Silicone
Glycerol Emulsifier uses its remarkable capabilities to bring an enhanced sensory experience to your customers. With the growth of higher performance cosmetics, customers now expect longer-lasting use and greater color intensity. DOWSIL™ ES-5600 Silicone Glycerol Emulsifier can make your products more attractive, intensely colorful, smoother in texture, more comfortable and easier to wear.
Because of their longer-last effects against sebum and water, water-in-oil (W/O) formulations are preferred for liquid foundations and color cosmetics. The oil-phase flexibility of Dow DOWSIL™ ES-5600 Silicone Glycerol Emulsifier helps to create a stable formulation. Its powder dispersing capabilities allow better formulation with pigments and powders.
