Polyglyceryl-2 Stearate

What is Polyglyceryl-2 Stearate?

Polyglyceryl-2 Stearate is a non-ionic surfactant formed by linking polyglycerol-2, a short-chain polymer made from glycerol sourced from vegetable oils, with stearic acid, a common saturated fatty acid derived from plant or animal lipids. In cosmetics, it typically appears in plant-based versions for clean beauty appeal. This ingredient falls into the category of mild polyglyceryl esters, prized for their gentle profile in rinse-off and leave-on products like moisturizers, lotions, and facial cleansers. It functions by reducing interfacial tension between oil and water phases, creating stable emulsions with smooth consistency. Additionally, its fatty acid chain delivers emollient action, helping to soften the skin's surface and enhance product spreadability without heavy residue.

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

Provides emollient effects to soften and smooth skin texture.

Acts as an emulsifying agent for stable lotion and cream formulations.

Supports surfactant properties for effective yet mild cleansing.

Who It's For
