Science
Mechanism of Action
This compound primarily functions as an emollient, delivering significant softening and smoothing effects to the skin. Additionally, it acts as an emulsifier, stabilizing oil-in-water or water-in-oil emulsions by reducing the interfacial tension between otherwise incompatible substances.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed PEGs Laurate, including PEG-9 Laurate, safe for cosmetic use at concentrations up to 25%. A crucial restriction is the potential for trace amounts of carcinogenic impurities like 1,4-dioxane and unreacted ethylene oxide, necessitating stringent purification protocols during manufacturing. While studies on intact skin showed no evidence of systemic toxicity or sensitization, it is noted that PEGs were readily absorbed through damaged skin, leading to observed sensitization and nephrotoxicity in burn patients treated with PEG-based creams. The ingredient also holds general or specific limited use approval in food by the U.S. FDA.
