STEARETH-8

Safety grade: A

Steareth-8 is a gentle cleaning and mixing agent made by combining a natural fatty acid (stearic acid) with a plant-derived sugar-like substance. It helps blend oil and water-based ingredients together in cosmetic products.

This ingredient acts as an emulsifier and surfactant to combine incompatible ingredients (like oil and water) into a smooth, stable product while providing mild cleansing properties.
