Key Properties
Triethanolamine lauryl sulfate is an anionic surfactant that serves as a mild cleansing agent, primarily utilized in personal care formulations. This compound is notable for its ability to create stable foams and emulsions, making it a popular choice in the cosmetic and personal care industries. Its mildness makes it suitable for sensitive skin applications, and it is often found in shampoos, body washes, and facial cleansers. The compound is derived from lauryl alcohol and triethanolamine, combining the properties of both to enhance cleansing efficacy while minimizing irritation.
Also known as Lauryl triethanolamine sulfate.
