Description

Polyglyceryl-2 Sesquistearate is a non-ionic, lipophilic emulsifier derived from vegetable sources, offering excellent stability and skin compatibility. Its primary value lies in its ability to create stable water-in-oil (W/O) emulsions and enhance the texture and sensory properties of finished formulations. This versatile ingredient is essential for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking high-performance, natural-derived emulsifiers.

Application

• Primary emulsifier for stable water-in-oil (W/O) creams and lotions in skincare.
• Key component in makeup products such as foundations, lipsticks, and mascaras for pigment dispersion and smooth application.
• Used in sunscreen formulations to stabilize active ingredients and improve water resistance.
• Functions as a co-emulsifier and consistency regulator in deodorant sticks and antiperspirants.
• Improves the texture and stability of pharmaceutical ointments and topical delivery systems.
• Employed in hair care products like conditioning treatments and styling creams.
