Sodium Stearate
What is Sodium Stearate?
Sodium Stearate is a salt derived from stearic acid, which is a naturally occurring fatty acid. It is typically created by saponification, a process that involves treating stearic acid with sodium hydroxide.
This ingredient is commonly used as a surfactant and emulsifier in personal care products like deodorants and soaps. It helps to stabilize formulations and improve the texture. Scientifically, sodium stearate is generally considered safe for topical use, though its effectiveness or safety in other applications is less documented.
When you see Sodium Stearate on a label, it is often there to help blend ingredients together and to create a creamy, smooth consistency in products, particularly in cosmetics and personal hygiene products.
Commonly found in: Deodorants, Soaps, Shaving Creams, Cosmetics, Lotions
Sodium stearate is generally recognized as safe (GRAS) by the FDA for use in cosmetics.
Research indicates sodium stearate is effective as an emulsifier and surfactant in topical applications without significant health risks.
Sodium stearate can be derived from animal fats, but it is also commonly sourced from plant oils, so its vegan status depends on the source.
