In the cosmetics industry, sodium stearate is indispensable and is commonly found in a wide range of products such as soaps, shampoos, deodorants and make-up. Its excellent thickening properties and fullerene capabilities make it a key ingredient in the manufacture of eye and eyebrow pencils. Sodium stearate also has uses in the food industry. It is a component of some baked goods, confectionery or chocolate. It is also produced as part of some additives for industrial use, for example as an additive for plastics and rubber, because it improves their mechanical properties. In terms of safety, it is a non-toxic substance that is recognised as safe in cosmetic products.
