Science
Mechanism of Action
This ingredient functions primarily by reducing the interfacial tension between oil and water, enabling the formation of stable, homogeneous emulsions essential for product consistency. As a polyethylene glycol derivative, it deeply conditions the skin, enhancing its softness and elasticity, which is especially beneficial for dry or mature skin types. Additionally, it helps to strengthen the skin's protective barrier by aiding in moisture retention and serves as a texture enhancer, preventing product separation.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed PEGylated alkyl glycerides, including PEG-5 Glyceryl Sesquioleate, safe for cosmetic use when formulated to be non-irritating on intact skin. Manufacturers are strongly encouraged to ensure the removal of impurities such as ethylene oxide and 1,4-dioxane. Caution is advised against using this ingredient or other PEGs on damaged or injured skin due to a potential for sensitization observed under such conditions.
