Properties

Sodium oleate is a white to pale yellow flaky or powdery solid, classified as an anionic surfactant and fatty acid salt. It is soluble in water and ethanol, forming colloidal solutions, but insoluble in non-polar solvents (e.g., hexane).

Exhibits excellent emulsifying, foaming, and dispersing properties. Stable under normal conditions but incompatible with strong acids (releases oleic acid) and oxidizing agents.

Applications

Mining & Mineral Processing

Widely used as a collector in froth flotation for oxides (e.g., hematite, fluorite) and silicates.

Effective in phosphate and tungsten ore beneficiation (pH 8–11).

Cosmetics & Soaps

Acts as an emulsifier and thickener in shampoos, shaving creams, and liquid soaps.

Metalworking

Serves as a lubricant in wire drawing and metal stamping.

Pharmaceuticals

Used as a tablet lubricant and in topical formulations.

Other Uses

Biodegradable detergent component.

Rubber and polymer additive (mold release agent).

Packaging & Storage

Standard Packaging: 25 kg/bag or customized

Store in a cool, dry, and ventilated area. Keep away from strong acids, oxidizers, and moisture. Tightly seal containers to prevent caking.
