Sodium Oleate, identified by CAS number 143-19-1, is a fascinating chemical compound whose scientific properties underpin its extensive utility across a spectrum of industries. As an anionic surfactant and the sodium salt of oleic acid, its molecular structure dictates its behavior and performance, making it a go-to ingredient for formulators worldwide.

Chemically, Sodium Oleate (C18H33NaO2) is characterized by its amphipathic nature. It possesses a long, nonpolar hydrocarbon chain derived from oleic acid, which provides lipophilic (oil-attracting) properties. Simultaneously, it features a polar, ionic carboxylate group that is hydrophilic (water-attracting). This dual characteristic is the hallmark of surfactants, enabling them to interact with both oil and water phases, thus reducing interfacial tension. This fundamental property makes Sodium Oleate an exceptionally effective emulsifier, facilitating the creation of stable mixtures from otherwise immiscible liquids.

When dissolved in water, Sodium Oleate solutions tend to be alkaline. Its solubility in water is moderate, and it readily forms micelles in dilute aqueous solutions due to the self-assembly of its hydrophobic tails away from water and towards each other, while the hydrophilic heads face outwards towards the water. This micelle formation is crucial for its cleansing action, as it encapsulates oils and dirt, allowing them to be washed away with water.

The production of Sodium Oleate typically involves the saponification of oleic acid with sodium hydroxide. This reaction yields Sodium Oleate and water. The purity of the final product is critical for many applications, especially in pharmaceuticals and high-end cosmetics. Manufacturers often offer different grades, with purity levels varying, impacting performance and price. For those looking to buy Sodium Oleate, understanding the grade and its specifications is vital.

Its functional roles are diverse: in cosmetics, it acts as a cleansing agent, foaming agent, and emulsifier, contributing to the texture and efficacy of personal care products. In the pharmaceutical industry, it serves as an excipient, aiding in the solubilization and delivery of drugs. Industrially, it functions as a waterproofing agent in textiles, a flotation agent in mining, and a dispersant in paints and coatings. The consistent demand across these sectors highlights its importance as a versatile industrial chemical.
