Polyglyceryl-4 Laurate

What is Polyglyceryl-4 Laurate?

Polyglyceryl-4 laurate is a non-ionic emulsifier and surfactant synthesized from polyglycerol-4 and lauric acid. Polyglycerol-4 comes from polymerizing glycerin sourced from vegetables like soy or palm, while lauric acid derives from coconut or palm kernel oils, making it a nature-inspired compound. In cosmetics, it appears in cleansers, shampoos, lotions, and micellar waters within the surfactant and emulsion-stabilizing categories. It works by positioning itself at oil-water interfaces, creating a protective film that prevents separation and ensures even texture in products. As a surfactant, it reduces surface tension to lift dirt and oils during cleansing while supporting light foam. Its emollient nature adds slip and smoothness, mimicking natural skin lipids to enhance product feel without heaviness. This multifunctional profile supports its use in gentle, everyday formulations seeking stability and mild performance.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.
Surfactant
Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.

Benefits

Softens and smooths skin surface for improved texture.

Supports mild cleansing by effectively removing impurities.

Helps create stable emulsions for consistent lotion and cleanser textures.
