| Description |
As the sodium salt of stearic acid, sodium stearate is a highly functional material that can be applied in various fields, especially in cosmetic formulations, where it is effective to stabilize emulsions like lotions, make products thicker, more viscous. It is also widely used in the deodorant produce, in which it can serve as a major constituent of soap produced by saponification of oils and fats.
