Product Technical Details

Product Overview

Polyglyceryl-4 Caprate is a premium, non-ionic surfactant derived from renewable resources, widely recognized for its excellent emulsifying, solubilizing, and skin-friendly properties. With a purity of at least 98%, this ingredient is specifically engineered for use in sensitive cosmetic applications where mildness and biocompatibility are paramount. Its unique molecular structure—comprising a polyglycerol backbone esterified with capric acid—enables stable oil-in-water emulsions without the need for ethoxylated compounds, making it a preferred choice for clean-label and natural cosmetic formulations.
