Steareth 20

Steareth 20 is a synthetic compound derived from natural fatty alcohols and ethylene oxide. It belongs to a group known as polyethylene glycol ethers, which are widely used in personal care, supplement, and pharmaceutical topical products. Its primary function as an emulsifier is to stabilize formulations where oil and water components need to be mixed, preventing separation and keeping the formula uniform. Steareth 20 is not a nutrient, nor does it occur naturally in foods, but is produced industrially from naturally sourced stearic acid (often from plant or animal fats) and chemically modified for use in formulations. In supplements like KeraBiotics, which are applied topically, Steareth 20 contributes to the even distribution of active ingredients across the surface of the nails or skin. When checking labels, Steareth 20 is typically present at low concentrations, reflecting its functional, rather than active, role in the formula. It is valued for being non-irritating and making products feel more pleasant upon application.
