Polyglyceryl-10 Decaoleate

What is Polyglyceryl-10 Decaoleate?

Polyglyceryl-10 Decaoleate is a non-ionic surfactant formed by esterifying polyglycerol-10, a chain of ten glycerol molecules, with ten units of oleic acid, a fatty acid typically sourced from vegetable oils like sunflower or olive. It belongs to the polyglyceryl ester family, prized in clean beauty formulations as a polyethylene glycol-free alternative. Primarily used in lotions, creams, cleansers, and makeup removers, it works by reducing surface tension at the oil-water interface, forming stable emulsions that prevent separation and deliver smooth textures. Its emollient properties arise from the oleic acid chains, which mimic skin's natural lipids to enhance spreadability and provide a lightweight conditioning effect without greasiness.

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.

Skin conditioning agent

Maintains skin softness, smoothness, and flexibility.

Benefits

Provides a soft, smooth feel by mimicking skin lipids.

Stabilizes emulsions for even product texture and application.

Supports gentle cleansing without stripping moisture.

Who It's For

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

Individuals with dry or rough skin seeking conditioning agents.	Those with rare allergies to oleic acid or glycerol derivatives.
Users preferring mild surfactants in daily cleansers.	Individuals sensitive to vegetable oil-derived ingredients.
People formulating or using stable, lightweight emulsions.	People preferring fully anhydrous or surfactant-free products.

Safety Notes

Rated low hazard by safety databases with minimal irritation reports.
Non-comedogenic, unlikely to clog pores based on ratings.
