Steareth-20
What is Steareth-20?
Steareth-20 is a synthetic emulsifier made by reacting stearyl alcohol, derived from vegetable fats and oils, with 20 units of ethylene oxide. This process modifies the alcohol to improve its solubility and stability in formulations.
In products, Steareth-20 helps to mix oil-based and water-based ingredients, creating smooth and homogenous textures. It is commonly used in cosmetics and personal-care items like creams and lotions. The health evidence on Steareth-20 is limited, but it is considered safe for topical applications at low concentrations by regulatory authorities.
When you see Steareth-20 on a label, it generally indicates the product will have a consistent texture and improved application feel, without significant evidence of adverse health effects.
