What is Sodium Oleate?

Sodium oleate, also known as sodium octadecenoate, is an organic oil. The chemical formula is C17H33CO2Na. Sodium oleate is the primary element of soaps made of olive oil, etc, as well as likewise the primary component of tallow soap. It can also be prepared by the reaction of salt hydroxide as well as oleic acid.

Sodium oleate is a compound made up of 2 components: hydrophobic team as well as hydrophilic group, and also has outstanding emulsifying power, permeating power and detergency. It has good solubility in hot water and is used as anionic surfactant and fabric water repellent.

Its properties are those of ordinary salts, which cannot be volatilized and can be completely dissociated into ions in water. After adding inorganic acid (strong acid), the salt can be transformed into hydroxy acid and freed again.

When the warm soap option is allowed to cool, it does not crystallize, and the sodium oleate and the calcium as well as magnesium salts had in the difficult water kind insoluble calcium and also magnesium soap precipitation.
