Sodium Laureth Phosphate (AEP)

CAS 42612-52-2

Sodium Laureth Phosphate (CAS 42612-52-2) is an anionic surfactant belonging to the phosphate ester salt class. It is the sodium salt of phosphate esters of ethoxylated lauryl alcohol, with the general molecular formula C12H25O(C2H4O)nPO4Na2, where "n" represents the average degree of ethoxylation. The product is generally supplied as a clear to slightly yellow viscous liquid or paste, with a mild, characteristic odor. It is readily soluble in water and exhibits good stability across a wide pH range, being tolerant of hard water and high alkali concentrations, though hydrolysis may occur under strongly acidic conditions. Quality control parameters such as free amine and amine salt content, inorganic phosphate, and residual 1,4-dioxane (typically controlled below 30 ppm) are closely monitored to ensure product purity and safety for end-use applications.

>> Main Uses

Sodium Laureth Phosphate (AEP, CAS 42612-52-2) is a versatile anionic surfactant widely employed across personal care, household cleaning, and industrial applications. In personal care and cosmetics, it functions as a primary surfactant, cleansing agent, and emulsifier in shampoos, body washes, facial cleansers, bubble baths, and hair care products, delivering rich foaming, effective dirt and sebum removal, mild skin feel with low irritation, and antistatic conditioning benefits for hair. In household and industrial cleaning, it acts as a detergent, wetting agent, dispersing agent, and emulsifier in laundry detergents, dishwashing liquids, all-purpose cleaners, and heavy-duty degreasers, offering excellent soil suspension, grease removal, hard water tolerance, and alkali stability. Beyond these, it serves as a lubricant, antistatic agent, corrosion inhibitor, and emulsifier in textile processing, metalworking fluids, emulsion polymerization, pigment dispersion, and mining flotation processes, while its compatibility with other surfactants and thickening capabilities further enhance its formulation versatility across diverse industrial sectors.
