CIR ingredient: Sodium Stearate

Used in cosmetics, pharmaceuticals, food additives, waterproofing agents, plastic stabilizers, emulsifiers, and rubber lubricants and dusting agents; Stearic acid occurs naturally in human and animal fats and oils and in some vegetable oils, including cocoa oil. Stearic acid can be prepared from animal fat (triglyceride) by treating with water at high temperature, leading to hydrolysis of triglycerides, or by hydrogenation of unsaturated vegetable oils such as cottonseed oil. [ACGIH]

Used in pharmaceuticals (emulsifying and stiffening agent); in glycerol suppositories; in toothpastes; as waterproofing agent; as gelling agent; in cosmetics; as stabilizer in plastics; and as topical medication; [HSDB] Used in various cleaning products (most common ingredient in soap); as food additive (binder, emulsifier, and anti-caking agent); [CHEMINFO]

説明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.

使用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.

調製方法 · 2 件

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.

純化方法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.]
