Octadecanoic acid, sodium salt; Stearic acid, sodium salt; Natriumstearat (German); Estearato de sodio (Spanish); Stéarate de sodium (French) CAS NO: 822-16-2; sodium octadecanoate; 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. 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. The tail part dissolves the grease (or) dirt and forms the micelle. 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. 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 + 3 NaOH → C3H5(OH)3 + 3 C18H35O2Na
Purified sodium stearate can be made by neutralizing stearic acid with sodium hydroxide. octadécanoate de sodium, stéarate de soude,sodium octadecanoate, No CAS: 822-16-2, Le stéarate de sodium ou octadécanoate de sodium est le sel de sodium de l'acide stéarique. Il est obtenu par hydrolyse en milieu basique ou saponification de la stéarine. À température ambiante, c'est une poudre blanche qui est un des composés des savons durs. C'est une substance utilisée pour ses propriétés tensioactives. Outre les savons, elle est présente dans des préparations à destination de l'industrie chimique, pharmaceutique ou agroalimentaire. On la trouve dans de nombreux produits finis comme des bâtons de colle, sticks déodorants, crèmes à raser, préparations pour gâteaux ou crèmes glacées. SODIUM STEARATE
