Lauryl Alcohol Ethoxylate LAE-9 (PEG-9 Laurate, CAS No. 9004-81-3) is a nonionic surfactant widely used in various industrial and civil fields due to its efficient emulsifying and solubilizing capabilities, broad compatibility, and excellent wetting and penetrating properties. This product maintains chemical stability in acidic, alkaline, and high-hardness water environments and can be well compounded with anionic, cationic, and other nonionic surfactants.
In the field of daily chemicals and personal care products, LAE-9 serves as an O/W emulsifier for formulations such as creams and lotions to build stable oil-in-water systems, while also acting as a solubilizer to dissolve fragrances and oily active ingredients in transparent products like toners and shampoos. In household and industrial liquid detergents, this product significantly enhances detergency, effectively removing stubborn stains such as grease and sebum, and is suitable for high-temperature or high-alkaline environments.
In the textile industry, LAE-9 acts as a leveling agent to promote uniform dye penetration, and as a softener and antistatic agent to improve fabric hand feel and eliminate static electricity. In the agrochemical field, it is a key emulsifier for formulating environmentally friendly and efficient pesticide emulsifiable concentrates and emulsions. In metalworking fluids, it provides lubrication, cooling, and corrosion inhibition. In the leather industry, it serves as an emulsifying and dispersing carrier for fatliquoring agents, helping oils penetrate evenly to enhance the softness and elasticity of leather.

The HLB value of LAE-9 is suitable for O/W emulsion systems; it is recommended to adjust the dosage in formulations based on the type of oil. In detergent formulations, it can be compounded with other nonionic or anionic surfactants for synergistic effects. In pesticide EC formulations, it is recommended to use in combination with anionic emulsifiers (such as calcium salts) to enhance emulsion stability. When used in metalworking fluids, note that water hardness has minimal impact on product performance, which is a significant advantage over anionic types.
