Butanedioic acid, 2-sulfo-, 4-hexadecyl ester, sodium salt (1:2)

Description:
Butanedioic acid, 2-sulfo-, 4-hexadecyl ester, sodium salt (1:2), commonly known as sodium hexadecyl sulfosuccinate, is an anionic surfactant characterized by its long hydrophobic hexadecyl chain and a hydrophilic sulfosuccinate group. This compound is typically used in various applications, including cosmetics, pharmaceuticals, and as an emulsifying agent in food products. Its structure allows it to effectively reduce surface tension, making it useful in formulations that require improved wetting and spreading properties. The sodium salt form enhances its solubility in aqueous solutions, facilitating its use in liquid formulations. Additionally, it exhibits good stability and compatibility with other surfactants, which is advantageous in multi-component systems. The presence of the sulfonate group contributes to its excellent foaming properties and mildness, making it suitable for personal care products. Overall, this compound is valued for its functional properties in both industrial and consumer applications.
