Polyglyceryl-6 Polyricinoleate
What is Polyglyceryl-6 Polyricinoleate?
Polyglyceryl-6 Polyricinoleate is a non-ionic emulsifier produced by esterifying polyglycerol-6, a polymer of glycerol, with polyricinoleic acid derived from castor oil's ricinoleic fatty acid. This creates a lipophilic molecule suited for water-in-oil emulsions and anhydrous formulations like lipsticks, foundations, and mascaras. In products, it functions by lowering interfacial tension between oil and water phases, forming a stable interfacial film that prevents separation and ensures even texture. Its surfactant properties aid in dispersing pigments and improving spreadability, while emollient effects help mimic skin's natural lipids for a smooth application. Commonly found in color cosmetics and oil-based cleansers, it supports long-wear stability without compromising sensory feel.
