PEG-2 DIISONONANOATE.

Valuable / SURFACTANT - EMULSIFYING

PEG-2 Diisononanoate is a polyethylene glycol (PEG) derivative primarily functioning as a versatile emulsifier, adept at blending immiscible oil and water phases for stable cosmetic formulations. Beyond this key role, it also offers benefits as a surfactant, a mild cleansing agent, and contributes to skin conditioning and hydration.

Science

Mechanism of Action

This ingredient operates by reducing the surface tension between disparate liquid phases, facilitating the formation and stabilization of oil-in-water or water-in-oil emulsions. Its surfactant properties aid in dispersing and suspending impurities, contributing to effective cleansing. Additionally, it draws moisture to the skin as a humectant and provides a smoother skin feel through its conditioning action.

Safety

Safety Profile

CIR Status
Safe as used by CIR Expert Panel
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PEG-2 diisononanoate is safe for use in cosmetics at current concentrations and practices. As part of a broader group of PEG diesters, it has been found safe when formulated to be non-irritating. PEGs and their derivatives generally exhibit low ocular and dermal irritation, very low acute and chronic toxicities, and do not readily penetrate intact skin. An earlier caution regarding use on damaged skin has been removed by later assessments for related PEG derivatives. Manufacturers must ensure the removal of impurities such as ethylene oxide and 1,4-dioxane. It is generally prohibited in organic cosmetics due to its petrochemical origin.
