About
A specialty emollient combining PEG, the amino acid proline, and omega-3 linolenic acid — designed to deliver moisturising and skin-conditioning benefits.
PEG-4 Proline Linolenate is a polyethylene glycol ester incorporating L-proline and alpha-linolenic acid (an omega-3 fatty acid) with 4 moles of ethylene oxide. It functions as an emollient and skin-conditioning agent. The proline component supports collagen synthesis (proline is a key collagen amino acid), while linolenic acid provides anti-inflammatory and barrier-repair benefits. As a low-EO PEG derivative, 1,4-dioxane contamination risk is minimal but should be monitored. No GHS hazards or EU restrictions apply. Limited independent safety data exists for this specific compound.
