Ingredient
PEG-20 Glyceryl Triisostearate
What it is
A polyethylene-glycol ester of glyceryl triisostearate, used as a nonionic emulsifier that helps blend oil and water phases and can solubilize oils in water-based formulas such as micellar waters and toners.
How it works
Its PEG (hydrophilic) chain and triisostearate (lipophilic) tail let it sit at the oil-water interface, reducing interfacial tension to stabilize emulsions or solubilize oils.
