About
A highly ethoxylated PEG stearate with 36 moles of EO, functioning as a solubilizer and emulsifier with excellent skin tolerance.
PEG-36 Stearate is the polyethylene glycol (36 mol EO average) ester of stearic acid. The high ethoxylation degree gives it strong water solubility and a high HLB value (~17), making it suitable as a solubilizer for oils and fragrances in cosmetic formulations. The EU Cosmetics Regulation permits its use without restriction. High-EO PEG esters have minimal skin penetration and very low irritation potential; the large molecular size limits systemic absorption. SCCS guidance on residual solvents applies.
Skin benefits
- Solubilizes oils and fragrances
