What is PEG-32?

PEG-32, or polyethylene glycol with an average of 32 ethylene oxide units, is a synthetic, hydrophilic polymer derived from petroleum-based ethylene oxide through ethoxylation. It appears as a clear, viscous liquid commonly incorporated into moisturizers, cleansers, shampoos, and lotions. In formulations, it functions by attracting and retaining moisture to the skin's surface, dissolving both water- and oil-soluble actives for even distribution, and binding powders or solids to enhance product cohesion and stability. Its low molecular weight allows it to form flexible films that support hydration without greasiness. Regulatory bodies like the Cosmetic Ingredient Review assess it as safe for typical rinse-off and leave-on uses when manufactured to minimize impurities such as ethylene oxide residues. It contributes to smoother application and longer-lasting hydration in diverse personal care items.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Binder

Helps hold solid ingredients together to form cohesive tablets, compacts, or sticks, improving pressability, integrity, and wear of the finished product.

Humectant

Attracts and holds water in the stratum corneum, boosting hydration and plumpness; commonly used in moisturizers, cleansers, and hair conditioners.

Solvent

Dissolves and carries other ingredients, helping control viscosity, evaporation rate, and delivery of actives in both water- and oil-based systems.

Benefits

Supports cleansing by aiding removal of impurities.

Enhances moisturizing through water retention on skin.

Promotes softening for improved texture and feel.
