Polyoxyethylene laurate LAE-4 is a multifunctional nonionic surfactant, with core features including excellent emulsifying ability, superior chemical stability, and broad compatibility. It is widely used in various industries such as personal care, textiles, metal processing, and pesticide formulations.
Detailed Description
Polyoxyethylene laurate LAE-4 (CAS No.: 9004-81-3), chemically known as PEG-4 Laurate, is one of the flagship nonionic surfactant products manufactured by Haian Guoli Chemical Co., Ltd. This product is synthesized via the addition polymerization of lauric acid with 4 moles of ethylene oxide, appearing as a colorless to light yellow transparent liquid with good fluidity and ease of handling.
The core advantages of LAE-4 lie in its outstanding emulsifying ability, effectively constructing stable and fine oil\/water emulsion systems, while excelling in solubilization, wetting, and spreading. It possesses excellent chemical stability against acids, alkalis, and hard water, enabling adaptation to a wide range of production conditions and water quality. Additionally, LAE-4 exhibits good compatibility with anionic, cationic, and other nonionic surfactants, providing great flexibility for formulators.
In terms of safety, LAE-4 is classified as a low-toxicity chemical, with no significant health hazards under normal use conditions. It is non-flammable, non-explosive, and biodegradable, meeting the requirements of modern industry for green and environmentally friendly auxiliaries.

Application Suggestions
LAE-4 finds applications across multiple industries. Below are the main application scenarios and recommendations:
- Personal Care Products: Used as an emulsifier and solubilizer in creams, lotions, shampoos, and body washes, imparting good stability and smooth skin feel, with emollient properties.
- Textile Industry: Applied as an antistatic agent and softener to improve fiber processing performance, giving fabrics excellent hand feel and drape.
- Metalworking Fluids: Functions as an emulsifier and lubricant in cutting fluids and grinding fluids, enhancing metal processing precision and efficiency.
- Pesticide Formulations: Acts as an emulsifier in emulsifiable concentrates and oil-in-water emulsions, enhancing the spreading and penetration of the spray solution on plants and target surfaces.
- Industrial Hard Surface Cleaning: Used in cleaning formulations to significantly enhance the emulsification and removal of greasy dirt.
- Leather Processing: As a component of fatliquoring agents, making leather softer and fuller.
- Coatings and Inks: Serves as a wetting and dispersing agent to promote uniform distribution of pigments and fillers, improving system dispersion stability and leveling.
Precautions
- Recommended storage temperature is 5°C to 35°C; avoid prolonged exposure to extreme temperatures to prevent product separation or deterioration.
- Keep containers tightly sealed to prevent moisture absorption and foreign matter ingress; keep away from fire and heat sources.
- Operators are advised to wear chemical safety protection gloves, goggles, and work clothes, and maintain good ventilation in the work area.
- Avoid mixing storage with incompatible substances such as strong oxidizers, strong acids, and strong alkalis.
- Under proper storage conditions, the product shelf life is two years; if exceeding the shelf life, it must be tested and approved before continued use.
- In case of large spills, prevent entry into drains, surface water, or groundwater; dispose of harmlessly in accordance with local regulations.
