Where is Polyglyceryl-3 diisostearate used?

• Personal care and food-contact: stabilizes water-in-oil and oil-in-water emulsions
• Cosmetics: primary or co-emulsifier in anhydrous and low-water systems such as lip products, color cosmetics, and skin creams
• Sunscreen and color cosmetics: disperses pigments and UV filters uniformly within emollient bases
• Food-adjacent or edible coatings: polyglycerol ester structure supports emulsion stability in fat-based systems
• Coatings and adhesives: rheology modifier and dispersant for viscosity control
• It supports a smooth, even texture without a heavy feel in topical applications.
