Science
Mechanism of Action
PEG-20 METHYL GLUCOSE SESQUICAPRYLATE/SESQUICAPRATE operates by effectively reducing the surface tension at the oil-water interface, allowing for superior wetting and solubilization of ingredients and maintaining a uniform dispersion of oil droplets within aqueous systems. Concurrently, it binds water molecules, facilitating moisture retention within the skin and hair. This ingredient also contributes to the desired viscosity of formulations.

Stability
This ingredient exhibits excellent stability across a broad pH range, specifically between pH 3.0 and 10.0, making it suitable for diverse formulation types. It facilitates effective emulsification and stability even at low concentrations, enhances emulsion viscosity, and improves the compatibility of various surfactant systems, thereby preventing phase separation.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined this ingredient, along with related methyl glucose polyethers and esters, to be safe for use in current cosmetic practices. It is safely employed at concentrations up to 6% in rinse-off products and up to 10% in leave-on formulations. Acute oral toxicity data indicates a relatively non-toxic profile. Ocular irritation tests suggest it is mildly irritating to non-irritating, while skin irritation tests found it to be a slight irritant only when undiluted. Repeated insult patch tests confirmed it as a non-irritant and non-sensitizer. It is also included in the FDA's Voluntary Cosmetic Registration Program (VCRP).
