PEG-9 BUTYLOCTANOATE.

Insufficient Data / SURFACTANT - EMULSIFYING

PEG-9 Butyloctanoate is a synthetic ester that primarily functions as an emulsifier, expertly blending oil and water phases to create stable skincare formulations. As a polyethylene glycol (PEG) derivative, it also contributes to skin softening and may enhance the delivery of other active ingredients.

Emulsifier Emollient Penetration Enhancer

Science

Mechanism of Action

This ingredient operates as an effective emulsifier, stabilizing oil-in-water or water-in-oil emulsions to prevent ingredient separation and ensure product integrity. Additionally, polyethylene glycols generally possess emollient properties, which can lubricate and soften the skin's surface. Its structure also potentially facilitates improved penetration and absorption of other beneficial compounds into the skin.

The Cosmetic Ingredient Review (CIR) Expert Panel classified PEG-9 Butyloctanoate in 2014 as a 'Potential Add-on' for a re-review of related PEGylated esters. While similar PEGylated ingredients have been deemed generally safe when formulated to be non-irritating, a specific, standalone safety conclusion or maximum concentration for PEG-9 Butyloctanoate itself is currently unavailable. No explicit SCCS opinion or FDA cosmetic regulatory status was identified for this specific compound.
