PEG-8 Dilaurate

PEG / Ethoxylated

What is PEG-8 Dilaurate?

PEG-8 Dilaurate is a nonionic surfactant derived from esterifying two molecules of lauric acid, a saturated fatty acid from coconut or palm kernel oil, with polyethylene glycol (PEG-8), a polymer of ethylene oxide. This synthetic compound belongs to the PEG fatty acid ester family, commonly used in rinse-off and leave-on cosmetics like shampoos, body washes, moisturizers, and makeup removers. It functions by lowering surface tension between oil and water phases, enabling effective cleansing through micelle formation that traps dirt and oils. As an emulsifier, it stabilizes formulations by creating a protective film at the oil-water interface, preventing separation and ensuring even distribution of active ingredients. Its mild nature supports foaming in cleansers while contributing to lightweight, non-greasy textures in emulsions. Typical concentrations range in personal care products where it enhances product performance without residue.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

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

Supports thorough cleansing by reducing surface tension to lift away impurities.

Stabilizes oil-in-water emulsions for consistent lotion and cream textures.

Promotes foaming action in shampoos and washes for a satisfying lather.

Who It's For
