sodium stearate chemical formula

Sodium stearate is the sodium salt of stearic acid and is used in soaps, deodorants, rubbers, latex paints, inks and as a component of some food additives. It is a mild irritant to the skin and eyes, but is not toxic or harmful to the environment.

The chemical formula of stearic acid is composed of 18 carbons in a ring structure with both polar and non-polar parts. The polar end is a carboxylate and is hydrophilic, while the long non-polar hydrocarbon chain is hydrophobic.

It is a natural ingredient and can be derived from vegetable triglycerides obtained from coconut and palm oils or animal triglycerides such as lard and tallow. It can be halal, kosher pareve or gluten free depending on the source.

In addition to its role in soaps, sodium stearate is also a surfactant, an ingredient that helps water and oil mix together better. It is widely used in cosmetics and personal care products as an emulsifier and thickener.

Sodium Stearate is a surfactant with both hydrophobic and hydrophilic parts that help emulsify and disperse oils and fats into a thin layer, and make them easier to mix. This enables it to be used in soaps, deodorants and air fresheners.

It can also be made in the laboratory by neutralizing stearic acid with sodium hydroxide. It is slightly soluble in water and in ethanol (96 per cent).

Sodium stearate is one of the most common and useful carboxylic surfactants and is obtained by saponification of many types of animal fats and oils. It is found in many soaps, solid deodorants and in rubbers and in some types of paints, inks and accelerators.
