Science
Mechanism of Action
This ingredient functions as an emollient, delivering deep hydration and contributing to skin softness. As a surfactant, it effectively mixes with and lifts oil and dirt from the skin, facilitating their gentle removal. Furthermore, it acts as an emulsifier, enabling the stable and homogeneous blending of oil and water phases in products, which improves texture, spreadability, and supports the skin's moisture retention and barrier integrity.

The Formula
Formulation
Stability
PEG-20 Glyceryl Triisostearate exhibits stability under normal environmental conditions, with its functional groups demonstrating very slow hydrolysis within a pH range of 4.0 to 9.0. It integrates effectively into formulations due to its low melting point, below -10°C, and minimal acidity. An HLB value of approximately 7-8 underscores its efficacy in stabilizing emulsions.
Safety
Safety Profile
Deemed safe for cosmetic use by regulatory bodies including the CIR, FDA, and EWG, PEG-20 Glyceryl Triisostearate has undergone extensive toxicological assessment. It is considered non-irritating, non-comedogenic, and generally does not induce allergic reactions, though individuals with extremely sensitive skin may consider a patch test. Its high molecular weight, exceeding 1,000 g/mol, prevents significant skin penetration and bioaccumulation. While general product formulations can contain up to 20%, its concentration should not surpass 5% in leave-on applications. The EWG notes a potential for trace impurities, advocating for products that meet stringent contamination controls.
