Science

Mechanism of Action

Functioning as an emulsifier, surfactant, and solubilizer, PEG-20 ISOSTEARATE reduces surface tension between oil and water phases, allowing them to mix and form stable emulsions. This action is crucial for improving the spreadability and consistency of cosmetic products. It additionally offers mild cleansing capabilities and emollient properties, contributing to skin softness and product integrity.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has assessed the safety of structurally similar ingredients, such as PEG Stearates and Polysorbates (including PEG-20 Sorbitan Isostearate), concluding they are safe for cosmetic use when formulated to be non-irritating. PEG-20 Glyceryl Triisostearate has also undergone extensive toxicology review and is considered non-irritating and safe in both rinse-off and leave-on products. While a specific maximum concentration for the exact INCI name 'PEG-20 ISOSTEARATE' is not explicitly available, the broad safety profile of its related derivatives indicates a low risk.
