Polyglyceryl-5 Trioleate

What is Polyglyceryl-5 Trioleate?

Polyglyceryl-5 Trioleate is a non-ionic compound produced by esterifying polyglycerol-5, made from plant-based glycerol, with oleic acid sourced from vegetable oils such as olive or sunflower. This results in a multifunctional ingredient prevalent in lotions, creams, shampoos, and makeup removers. It functions primarily by lowering interfacial tension between oil and water, creating stable emulsions that prevent phase separation and deliver uniform textures. As an emollient, it deposits a lightweight lipid layer on the skin to enhance slip and suppleness. Its surfactant nature enables mild foaming and dispersion of oils in cleansing products. Biodegradable and compatible with natural formulations, it supports clean-beauty preferences while maintaining efficacy across rinse-off and leave-on applications.

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
