Benefits
Softening

What is Polyglyceryl-10 Pentastearate?

Polyglyceryl-10 pentastearate is a multi-functional ingredient created by linking polyglycerol-10, a chain of ten glycerol molecules typically sourced from vegetable glycerin, with five stearic acid chains from plant or animal fats. This results in a non-ionic surfactant and emulsifier commonly used in skincare formulations like lotions, creams, and cleansers. It works by reducing surface tension between oil and water phases, forming stable emulsions that prevent separation and ensure smooth textures. As an emollient, it mimics skin's natural lipids to soften the surface, while its surfactant properties enable light foaming and effective removal of impurities without stripping moisture. Often featured in gentle, everyday products for its compatibility with sensitive formulas.

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 softening effect by smoothing skin's surface and enhancing product spreadability.

Acts as an emulsifier to create stable, creamy textures in lotions and moisturizers.

Functions as a mild surfactant for effective yet non-drying cleansing in washes.

Who It's For

A quick guide for who this ingredient may suit (and who should be cautious).

Who May Benefit Who Should Avoid
Individuals with dry skin seeking added softness from emollient ingredients.
Anyone with known allergies to stearic acid or polyglycerol derivatives.
People preferring stable, non-separating emulsion-based moisturizers.
People sensitive to fatty acid esters in cosmetics.
Those using gentle cleansers who want low-irritation surfactants.
Individuals preferring completely anhydrous or surfactant-free products.

Safety Notes

  • Rated low hazard by EWG, indicating minimal health concerns in typical use.
  • Non-comedogenic, unlikely to clog pores or contribute to breakouts.
