PEG-18 Glyceryl Oleate/Cocoate

PEG / Ethoxylated

What is PEG-18 Glyceryl Oleate/Cocoate?

PEG-18 Glyceryl Oleate/Cocoate is a polyethylene glycol ether of a mixed glyceride ester, formed by reacting PEG-18 with glyceryl oleate from oleic acid and glyceryl cocoate from coconut-derived fatty acids. This ethoxylated ingredient belongs to the class of nonionic surfactants commonly found in rinse-off cleansers, shampoos, body washes, and leave-on emulsions like lotions. It works by reducing surface tension between oil and water phases, stabilizing mixtures to prevent separation and ensure even texture. As an emollient, it lubricates the skin surface, mimicking natural lipids to enhance spreadability and provide a silky feel. In surfactant roles, it aids gentle cleansing by loosening dirt and oils without harsh stripping, while its emulsifying properties support the creation of creamy, homogeneous formulations.

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

Enhances product texture by stabilizing oil-water blends for smooth application.

Softens skin surface, improving slip and reducing dryness feel.

Supports mild cleansing in washes, helping remove impurities effectively.
