Application

Poly(Ethylene Glycol) (N) Distearate is a versatile compound primarily utilized as an emulsifier in various applications, including personal care products, water treatment, and the textile industry. As a soft, off-white solid with a pH of 7.26 in a 10% dispersion, the substance is soluble in chlorinated solvents, light esters, and acetone, while its solubility in alcohols is limited and it is insoluble in glycols, hydrocarbons, and vegetable oils. Notably, it acts as a processing aid due to its distinctive chemical properties, such as variability in its saponification number and its response to the number of ethylene oxide units, which affect its hydrophilicity and lipophilicity. This ester of polyglycol finds essential use in oil-in-water type creams and lotions, offering adaptable emulsifying benefits when combined with other surfactants, which can help achieve desired hydrophilic-lipophilic balances in formulations. Its role extends importantly to systems involving astringent salts or strong electrolytes, and it has practical applications in intravenous infusions, demonstrating its broad functionality and significance in diverse industries.
