PEG-8 GLYCERYL LAURATE.

Questionable CAS 59070-56-3 / SURFACTANT - EMULSIFYING

PEG-8 Glyceryl Laurate is a multifaceted nonionic surfactant and emulsifier, vital for creating stable oil-in-water emulsions in diverse cosmetic applications. It also functions as an emollient, providing moisturizing benefits, and can enhance the penetration of other active ingredients into the skin. Its versatility extends to acting as a lubricant, opacifier, pigment dispersant, spreading aid, and viscosity modifier.

Science

Mechanism of Action

This ingredient operates by reducing the surface tension between immiscible phases, thereby stabilizing emulsions and facilitating the blending of oil and water components. On the skin, its surfactant properties aid in cleansing by helping water mix with oily residues and dirt for effective rinse-off. It can also temporarily disrupt the skin barrier, enhancing the transdermal diffusion of other substances. Furthermore, it imparts emollient properties that contribute to skin hydration and softness.

Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel deemed PEG-8 Glyceryl Laurate safe for use in cosmetics at concentrations up to 25%. However, due to the ethoxylation process, PEG compounds may contain trace impurities like ethylene oxide and 1,4-dioxane. Importantly, this ingredient should not be applied to broken or irritated skin, as studies noted kidney toxicity and sensitization in burn patients treated with PEG-based creams. While no evidence of systemic toxicity or sensitization was found on intact skin, EWG's Cosmetics Database rates PEG-8 Glyceryl Laurate as a moderate to high hazard, citing concerns about organ toxicity, potential contamination, and allergies.

Verdict

Questionable

A versatile surfactant and emulsifier, PEG-8 Glyceryl Laurate offers broad formulation and some skin benefits, but its use is questionable due to potential impurities and specific risks associated with application on compromised skin.
