Sodium stearate is the sodium salt of stearic acid. It is a fine, white powder. It is used in soaps, colour cosmetics, deodorants and in hair and skin care products.
Sodium stearate stabilises emulsions, which means it stops them from separating into the oil and water-based components.
It turns products opaque and thickens them.
In shampoos and other foaming products, sodium stearate helps to create luxurious, thick foam.
We use sodium stearate in some of our handmade soaps for its stabilising and thickening properties and its ability to make a product opaque. We also use it to create creamy white foam.
