PPG-3-MYRETH-3.

Valuable CAS 37311-04-9 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PPG-3-Myreth-3 is a synthetic polymer functioning as a versatile emollient and skin conditioning agent, particularly beneficial for dry skin types due to its barrier-enhancing and hydrating properties. It also exhibits efficacy as a surfactant and emulsifier, stabilizing cosmetic formulations.

Summary

emollient skin conditioning cleansing agent emulsifier

Science

Mechanism of Action

This ingredient operates by enhancing the skin barrier through the filling of intercellular gaps within corneocyte clusters, which effectively improves skin hydration and significantly reduces transepidermal water loss. In formulations, it acts as a surfactant and emulsifying agent, lowering interfacial tension to promote emulsion stability and homogeneity.

Safety Profile

CIR Status
Safe as used
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PPG-3-Myreth-3, along with other propylene glycols containing 3 or more propylene oxide units, is safe for use in cosmetic formulations provided it is formulated to be nonirritating. It is important to note that the ethoxylation reaction involved in its production may result in trace residues of ethylene oxide and 1,4-dioxane, both identified as carcinogenic. While product labels typically do not disclose these residues, a related compound, PPG-3 Benzyl Ether Myristate, has a low hazard rating (EWG score of 1). However, another related compound, PPG-3 Myristyl Ether, has been reported to cause serious eye irritation in 21.7% of instances.
