What is PolyAquol™ 2W and How is it Used in Cosmetics?
PolyAquol™ 2W is a patented polyglycerol-based O/W self-emulsifier that allows formulators to create stable, elegant emulsions without the need for co-emulsifiers or additional thickeners. Naturally derived, PEG-free, COSMOS approved, and vegan friendly, it is designed to mimic the skin’s own lamellar structure for superior stability and skin compatibility.
Its liquid-crystal generating ability supports long-lasting moisturisation, reinforces the skin barrier, and improves spreadability in creams and lotions. Perfect for green, clean and high-performance formulations.
