Stearic acid sodium salt

스테아린산 나트륨 C화학적 특성, 용도, 생산

개요

Sodium stearate is the sodium salt of stearic acid. This white solid is the most common soap. It is found in many types of solid deodorants, rubbers, latex paints, and inks. It is also a component of some food additives and food flavorings.

화학적 성질

white to off-white powder

용도

β-Lactamase inhibitor

용도

Pharmaceutic aid (emulsifying and stiffening agent). In glycerol suppositories; also in toothpaste; as waterproofing agent.

용도

sodium stearate is a fatty acid used as a waterproofing agent. Sodium stearate is one of the least allergy-causing sodium salts of fatty acids. It is non-irritating to the skin.

용도

Sodium Stearate is the sodium salt of stearic acid. it functions as a binder, emulsifier, and anticaking agent. it is used as a plasticizer in chewing gum base.

용도

Characteristic of soaps, sodium stearate has both hydrophilic and hydrophobic parts, the carboxylate and the long hydrocarbon chain, respectively. These two chemically different components induce the formation of micelles, which present the hydrophilic heads outwards and their hydrophobic (hydrocarbon) tails inwards, providing a lipophilic environment for hydrophobic compounds. It is also used in the pharmaceutical industry as a surfactant to aid the solubility of hydrophobic compounds in the production of various mouth foams.

생산 방법

Sodium stearate is produced as a major component of soap upon saponification of oils and fats. The percentage of the sodium stearate depends on the ingredient fats. Tallow is especially high in stearic acid content (as the triglyceride), whereas most fats only contain a few percent. The idealized equation for the formation of sodium stearate from stearin (the triglyceride of stearic acid) follows :
(C18H35O2)3C3H5 → C3H5(OH)3 + 3 C17H35CO2Na
Purified sodium stearate can be made by neutralizing stearic acid with sodium hydroxide.

정의

ChEBI: An organic sodium salt comprising equal numbers of sodium and stearate ions.

Safety Profile

Poison by intravenous route. When heated to decomposition it emits toxic fumes of Na2O.

Purification Methods

It is better to prepare it by adding a slight excess of octadecanoic acid to ethanolic NaOH, evaporating and extracting the residue with dry Et2O. [Beilstein 2 III 1003.]
