Kemsurf ESD is the excellent detergent, characterized by its remarkable performance, demonstrates enduring detergency in both brine and hard water, ensuring consistent efficacy across diverse water conditions. Its impressive solubility makes it particularly advantageous for alkaline liquid formulations, contributing to ease of use. As an excellent foaming agent, it enhances the cleaning process while showcasing pronounced thickening in the presence of sodium chloride, adding versatility to its applications. Notably stable to aqueous ions, this detergent maintains its effectiveness in hard water, with superior lime soap dispersing properties due to the solubility of the calcium salt. However, it is essential to note that its chemical and temperature stability is subject to hydrolysis in acidic pH and high temperatures, making it unsuitable for use above 50°C. In summary, this detergent stands out for its versatile cleaning capabilities, solubility, foaming performance, and compatibility with water conditions, albeit with specific limitations in terms of pH and temperature.
