PEG-8 GLYCERYL TRILAURATE.

Optional / VISCOSITY CONTROLLING

PEG-8 Glyceryl Trilaurate is a polyethylene glycol (PEG) derivative primarily functioning as a surfactant and emulsifier, enabling the stable blending of immiscible oil and water phases. It also acts as a solubilizer, improving the uniform dispersion of challenging ingredients, and may contribute humectant properties to enhance skin hydration.

Science

Mechanism of Action

This ingredient functions on the skin through its surfactant and emulsifying capabilities, promoting the creation of homogenous, stable emulsions within formulations. Its solubilizing action aids in the uniform distribution of oil-soluble components within water-based systems. Additionally, as a PEG derivative, it may draw moisture into the skin, supporting hydration and potentially improving the dermal absorption of co-formulated active ingredients.

25%
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel assessed related PEGylated laurate compounds (e.g., PEG-8 Laurate, PEG Dilaurates) as safe for cosmetic use at concentrations up to 25%. However, specific safety data for PEG-8 Glyceryl Trilaurate is limited. Manufacturers must ensure purification to remove potential impurities such as ethylene oxide and 1,4-dioxane. It is not recommended for use on sensitive or damaged skin due to potential irritation or toxicity concerns. The U.S. FDA has approved related PEG Dilaurate ingredients for specific indirect food contact applications.

Our Assessment

Verdict

Optional

While offering valuable formulation benefits as an emulsifier and solubilizer, its use is optional and requires careful consideration for sensitive or damaged skin, along with strict control over potential impurities, due to limited ingredient-specific safety data.
