Emulsifying Solubilizing Skin Conditioning Humectant Surfactant Viscosity Controlling Solvent Pigment Dispersing Stabilizing

Science

Mechanism of Action

This ingredient functions as an effective emulsifier and solubilizer, creating stable formulations by preventing the phase separation of oil and water components. It refines the sensory experience of products by enhancing texture and spreadability. At a dermal level, it actively contributes to skin hydration, bolstering the natural moisture barrier and mitigating dryness, thereby providing a conditioning effect. Furthermore, it facilitates the efficient delivery and absorption of active ingredients into the skin, thereby amplifying their performance. In cleansing formulations, it acts as a mild surfactant, reducing potential irritation from harsher cleansing agents while concurrently improving foam quality and overall product stability. It also serves as a humectant, a solvent, and aids in the uniform dispersion of pigments.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

PEGs and their derivatives, including PEG-90 Glyceryl Isostearate, are deemed safe for cosmetic applications provided they adhere to stringent manufacturing standards and purification protocols. Critical concerns revolve around potential impurities such as ethylene oxide and 1,4-dioxane, which are byproducts of the ethoxylation process; reputable suppliers are mandated to ensure these are minimized below international safety thresholds, such as those set by the EU and FDA. While generally considered non-toxic and mild, some individuals with highly sensitive skin may experience mild irritation or allergic reactions. It has been classified as 'Generally Recognized as Safe (GRAS)' by the US FDA for household cleaners.
