Peg-4 Dilaurate ●
TL;DR. This ingredient is a nonionic emulsifier and solubilizer that helps disperse oils, fragrance materials, and other lipophilic components into water-based formulas. It can also support mild cleansing and texture in surfactant systems.
What does Peg-4 Dilaurate do in a cosmetic formula?
This ingredient is a nonionic emulsifier and solubilizer that helps disperse oils, fragrance materials, and other lipophilic components into water-based formulas. It can also support mild cleansing and texture in surfactant systems.
Is Peg-4 Dilaurate clean?
Clean-beauty frameworks often flag it because it is made through ethoxylation, a process associated with trace impurities such as 1,4-dioxane when purification is not tightly controlled. It is not usually a high-irritation material, but its processing route creates restricted-list friction.
Is Peg-4 Dilaurate sustainable?
This material combines a petrochemical-derived ethoxylated segment with fatty feedstocks that are often sourced from coconut or palm-kernel supply chains. Its fatty portion is more biodegradable, but the ethoxylated chemistry and possible palm linkage make the sustainability profile mixed.
Is Peg-4 Dilaurate COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic because ethoxylated ingredients sit outside the standard’s allowed processing rules. From a Green Chemistry lens, partial fatty-feedstock content is outweighed by petrochemical ethoxylation and the need for impurity controls.
How does Peg-4 Dilaurate work chemically?
The molecule is a nonionic diester with two C12 fatty chains attached to a short ethoxylated hydrophilic spacer, giving it a relatively low-HLB emulsifying profile. It is typically used at low single-digit percentages as a co-emulsifier or solubilizer and is generally stable in normal cosmetic pH ranges, though ester bonds can hydrolyze under strongly acidic or alkaline conditions.
