Used as an emulsifier and surfactant, particularly for water-in-oil (W/O) emulsions, in cosmetic and pharmaceutical formulations. Helps stabilize W/O emulsions by reducing surface tension between ingredients. Commonly found in ointments, creams, and some lotions to improve texture and consistency. Enhances the incorporation of aqueous phases in oil-based systems, aiding in uniform application and absorption. Also serves as a solubilizer for fragrances and essential oils in personal care products. Its mild, non-ionic nature makes it suitable for sensitive skin formulations. This is a specialty chemical used as a niche additive in formulations.
