sodium stearate chemical formula is C17H35CO2Na and it is a salt of the fatty acid stearic acid. It is a tertiary carboxylic acid, which is often used as a surfactant in various products, including soaps and detergents.

Stearic acid is a naturally occurring saturated fatty acid that can be sourced from either animal fats and oils (lard, tallow) or vegetable oil sources such as palm, coconut, and rapeseed oil. It is usually present in the form of triglyceride, which has long hydrocarbon chains and glycerine molecules attached to them.

It is a common ingredient in most types of commercial soaps. It also is used in solid deodorants, rubbers, latex paints, and as an accelerator for many types of printing inks.

The molecule of sodium stearate is composed of both hydrophilic and hydrophobic parts which makes it a very stable emulsifier in water, as well as a very useful thickening agent. It is mainly used as a detergent in soaps and other personal care products because of its excellent ability to dissolve oily substances.

Sodium stearate is an effective and inexpensive additive that can be used in numerous applications, as well as in food production. It is an approved food additive by the FDA and European authorities, as well as many other national and international regulatory bodies.

It is a mild, safe, biodegradable ingredient that can be used in most industries and applications. Besides being a detergent, it can be used as a lubricant and as a thickening agent in food. It is also widely used in pharmaceuticals as a stearate, emulsifier, and anticaking agent.
