What is Sodium Oleate Powder?

Sodium oleate powder is the sodium salt of oleic acid, a long-chain fatty acid derived from various natural sources, primarily vegetable oils. This compound is widely recognized for its role as a surfactant and emulsifying agent, making it essential in numerous industrial applications. Produced through the saponification of oleic acid with sodium hydroxide, sodium oleate exhibits unique properties that contribute to its efficacy in various formulations.

Chemical Properties of Sodium Oleate

The chemical formula for sodium oleate is C₁₈H₃₃NaO₂. This compound is a white to off-white powder that is soluble in water and alcohol. Sodium oleate possesses a high melting point of around 253 °C (487 °F) and a density of approximately 0.87 g/cm³. Its amphipathic nature allows it to interact with both hydrophilic and hydrophobic substances, making it a versatile agent in numerous applications.

Physical and Chemical Characteristics

Sodium oleate is characterized by its:

• Surfactant Properties: Acts as an effective emulsifier and stabilizer in various formulations.


• Biodegradability: Environmentally friendly, breaking down naturally in various conditions.


• Viscosity: Exhibits low viscosity in solutions, facilitating easier handling and application.

Manufacturing Process of Sodium Oleate Powder

The production of sodium oleate powder typically involves the following steps:

Saponification Reaction

The manufacturing begins with the saponification of oleic acid. By reacting oleic acid with sodium hydroxide (lye), we produce sodium oleate and water. The reaction can be represented as follows:

C18H34O2 + NaOH → C18H33NaO2 + H2O

Neutralization and Drying

After the saponification, the mixture is neutralized, and the resulting sodium oleate is filtered and purified. The moisture content is then reduced through a drying process, yielding a fine powder.
