Introduction to Ethyl 2-Sulfolaurate Sodium | CAS 7381-01-3

Ethyl 2-Sulfolaurate Sodium, with the chemical formula C2H5NaOS, is a derivative of lauric acid, which is a saturated fatty acid. It is commonly known by its CAS number, 7381-01-3, and is used in a variety of applications due to its unique chemical properties. This compound is an organic sodium salt, which is synthesized through the reaction of ethyl laurate with sodium hydroxide. Its significance in various industries, such as pharmaceuticals, cosmetics, and agriculture, makes it a subject of considerable interest.

Chemical Properties

Ethyl 2-Sulfolaurate Sodium is a white to off-white crystalline solid that is soluble in water and organic solvents. It has a melting point of approximately 120°C and a boiling point of around 300°C. The compound is characterized by its strong sulfonic acid group, which imparts it with excellent detergency and emulsifying properties. These properties make it a valuable ingredient in the formulation of cleaning agents, shampoos, and detergents.

Synthesis Methods

The synthesis of Ethyl 2-Sulfolaurate Sodium involves the reaction of ethyl laurate with sodium hydroxide. This process is typically carried out in an aqueous solution, where the ethyl laurate is first converted into its sodium salt, sodium laurate. The sodium laurate is then treated with sulfuric acid to introduce the sulfonic acid group, resulting in the formation of ethyl 2-sulfolaurate. The reaction is followed by neutralization with sodium hydroxide to obtain the final product.

Applications

Ethyl 2-Sulfolaurate Sodium finds extensive use in various industries. In the pharmaceutical sector, it is used as a surfactant in the formulation of oral and topical medications. In cosmetics, it serves as an emulsifier and stabilizer in creams, lotions, and shampoos. Additionally, it is employed in the agriculture industry as a herbicide and fungicide due to its ability to disrupt the cell membranes of plant pathogens.

Safety Considerations

While Ethyl 2-Sulfolaurate Sodium is generally considered safe for use in the concentrations typically found in consumer products, it is important to handle it with care. The compound can cause irritation to the skin, eyes, and respiratory system. Therefore, it is recommended to use appropriate personal protective equipment when handling it. Accidental ingestion or inhalation should be avoided, and proper disposal methods should be followed to minimize environmental impact.

Regulatory Status

Ethyl 2-Sulfolaurate Sodium is subject to regulatory oversight in many countries. The European Union has established maximum residue limits for the compound in food products, and it is also listed in the FDA's Inactive Ingredients Database. Compliance with these regulations is essential for manufacturers to ensure the safety and efficacy of their products.
