Overview of Sodium Oleate

Sodium oleate is also known as sodium octadecenoate, sodium oleate is organic oil, chemical formula C17H33Co2Na, white to yellow powder or light yellow brown coarse powder or block.

Sodium Oleate Properties


In the air, it can slowly oxidize and color, darken the color, and produce rancid odor. This is due to the cleavage of the double bond of oleic acid due to oxidation to produce rancid substances such as nonanal. Incorporation of highly unsaturated acids promotes spoilage.


Dissolve in 10 times the amount of water, foam and form a viscous liquid. The aqueous solution is alkaline, and the liquid becomes milky due to partial hydrolysis into insoluble acidic soap and sodium hydroxide. It is not hydrolyzed in ethanol and is neutral. Dissolved in about 20 times the amount of ethanol. Almost insoluble in ether, petroleum ether and other organic solvents.

Hydrolysis reaction: 2RCOONa+H2O=RCOONa·RCOOH+NaOH.

chemical reaction

Reacts with metal ions other than alkali metals to form metal salt precipitation.

other properties

In general, the nature of salt is that it cannot be volatilized, and can be completely dissociated into ions in water. After adding inorganic acid (strong acid), the salt can be changed into hydroxy acid and freed again. When the hot soap solution is allowed to cool, it does not crystallize, and forms insoluble calcium and magnesium soap precipitates with calcium and magnesium salts contained in hard water. Appearance and Properties: White powder; Density: 0.9 g/cm3; Melting point: 232-235°C(lit.); Boiling point: 359.999ºC at 760 mmHg; Flash point: 270.099ºC; Stability: Stable. Incompatible with strong oxidizing agents . Storage conditions: -20ºC.


Application of sodium oleate

Sodium oleate is one of the main ingredients of soap and can be used as an emulsifier. Sodium oleate is used in medicine. It is used to treat cholelithiasis. In various oil-based cosmetics, sodium oleate is used as detergent, emulsifier, surfactant, thickener or gelling agent, and viscosity control agent. Examples of sodium oleate are as follows:

Sodium oleate is the main ingredient in soaps and tallow soaps made from olive oil and other substances.

Sodium oleate is used as a food coating agent. Such as plant surface coating, can be used in conjunction with ethylene oxide and high boron fatty alcohol.

Sodium oleate can be used as a corrosion inhibitor for aluminum and its alloys, iron, copper and other metals in neutral or acidic solutions.

Sodium oleate is used as an anionic surfactant and fabric water repellent.

Sodium oleate is used in medicine. It is used to treat cholelithiasis.
