Triethylene glycol dodecyl ether sulfate sodium salt

Description:
Triethylene glycol dodecyl ether sulfate sodium salt, with the CAS number 13150-00-0, is an anionic surfactant commonly used in various applications, including personal care products and industrial formulations. This compound features a hydrophilic triethylene glycol moiety and a hydrophobic dodecyl ether chain, which contribute to its surfactant properties. It is typically characterized by its ability to lower surface tension, enhance wetting, and improve emulsification, making it effective in cleansing and foaming formulations. The sodium salt form enhances its solubility in water, allowing for easy incorporation into aqueous systems. Additionally, it exhibits good stability across a range of pH levels and temperatures, although its performance can be influenced by the presence of electrolytes. Triethylene glycol dodecyl ether sulfate sodium salt is generally considered to be mild and non-irritating, making it suitable for use in cosmetic and personal care products, such as shampoos and body washes. However, as with all surfactants, its environmental impact and biodegradability should be considered in formulation and disposal practices.
