:

Sodium octyl sulfate

Description:
Sodium octyl sulfate, with the CAS number 142-31-4, is an anionic surfactant commonly used in various applications, including detergents, emulsifiers, and wetting agents. It is characterized by its long hydrophobic octyl chain, which imparts surface-active properties, allowing it to reduce surface tension in aqueous solutions. This compound is typically soluble in water, forming micelles that can encapsulate oils and other hydrophobic substances, making it effective in cleaning and emulsifying formulations. Sodium octyl sulfate is known for its ability to enhance the solubility of poorly soluble compounds and is often utilized in laboratory settings for protein solubilization and extraction processes. Additionally, it exhibits good stability under a range of pH conditions, although its performance may vary with temperature and ionic strength. Safety data indicates that, while it can be irritating to skin and eyes, it is generally considered safe for use in regulated concentrations. As with all chemical substances, proper handling and adherence to safety guidelines are essential to mitigate any potential risks.
