Polyglyceryl-4 Caprylate

What is Polyglyceryl-4 Caprylate?

Polyglyceryl-4 Caprylate is an ester derived from polyglycerol, produced by polymerizing vegetable glycerin, and caprylic acid sourced from coconut or palm kernel oils. This creates a multifunctional ingredient commonly used in rinse-off and leave-on cosmetics such as cleansers, lotions, and serums. It acts as a surfactant by lowering surface tension to improve cleansing and as an emulsifier to blend immiscible oil and water phases, resulting in stable, smooth-textured products. Its mild nature supports gentle formulation design, particularly in products for daily use, without compromising performance.
