Sodium undecyl sulfate

Description:
Sodium undecyl sulfate, with the CAS number 1072-24-8, is an anionic surfactant commonly used in various applications, including personal care products, detergents, and industrial formulations. It is characterized by its long hydrophobic undecyl chain, which enhances its ability to reduce surface tension and improve wetting properties. This compound is typically a white to off-white powder or solid, soluble in water, and exhibits good foaming properties. Sodium undecyl sulfate is known for its emulsifying and dispersing capabilities, making it effective in stabilizing emulsions and suspensions. Additionally, it possesses mild cleansing properties, which makes it suitable for use in formulations intended for sensitive skin. Its anionic nature allows it to interact with cationic and nonionic surfactants, providing versatility in formulation chemistry. However, like many surfactants, it should be handled with care, as it may cause irritation to the skin and eyes upon contact. Overall, sodium undecyl sulfate is valued for its functional properties in both consumer and industrial applications.
