Steareth-100
What Steareth-100 is & what it does
A highly ethoxylated emulsifier and solubilizer that disperses oils into water and stabilizes emulsions. It supports smooth, uniform textures.
What does Steareth-100 do in skincare?
Steareth-100 is an ethoxylated fatty alcohol used mainly as a surfactant and emulsifier in cosmetics. It helps oil and water phases blend into a stable cream or lotion and can also contribute to a product's texture.
Is Steareth-100 safe in skincare?
Steareth-100 is a commonly used emulsifier that is generally considered safe at the concentrations found in cosmetic products. As with any ingredient, people with sensitive skin can patch test, and the finished formula's overall balance matters more than any single component.
Is Steareth-100 natural or synthetic?
Steareth-100 is synthetic, made by reacting stearyl alcohol with ethylene oxide in a process called ethoxylation. The starting fatty alcohol can be plant or petroleum derived, but the final ingredient is a processed, synthetic emulsifier.
