PEG-4 PROLINE LINOLEATE.

Questionable / SKIN CONDITIONING - EMOLLIENT

PEG-4 PROLINE LINOLEATE is a multi-functional derivative of polyethylene glycol, the amino acid proline, and the essential fatty acid linoleic acid. It primarily serves as a skin conditioning agent, imparting emollient and humectant properties to hydrate and smooth the skin's surface. This ingredient also contributes to reinforcing the skin barrier and offers antioxidant support.

Summary

Emollient Humectant Skin conditioning Solubilizer Skin barrier support Antioxidant Anti-inflammatory Penetration enhancer

Science

Mechanism of Action

This compound acts through its three primary components. The polyethylene glycol (PEG) segment functions as a humectant, effectively drawing and retaining moisture within the skin, and can facilitate the penetration of other active ingredients. Linoleic acid, an essential fatty acid, is crucial for maintaining the skin's barrier integrity, supporting wound healing, and exhibiting anti-inflammatory effects. Proline, an amino acid, bolsters the skin's metabolic stability and enhances its natural antioxidant defenses.

While the CIR Expert Panel has deemed PEG-4 safe for cosmetic use, the specific ingredient PEG-4 PROLINE LINOLEATE faces significant scrutiny. EWG Skin Deep flags high concerns regarding potential contamination by toxic impurities like ethylene oxide and 1,4-dioxane, particularly in inhalable applications. Furthermore, its record on precisionFDA is marked as 'FAILED,' indicating an incomplete polymer record and listing ethylene oxide as a monomer. Use in EWG VERIFIED products is permitted only when strict use restrictions are met.
