PEG400DL (Polyethylene Glycol 400 Dilaurate), as an efficient nonionic surfactant, is widely used in five major industries: personal care, industrial cleaning, textiles, pesticides, and coatings, primarily functioning as an emulsifier, solubilizer, dispersant, and low-foam lubricant.
Core Application Industries and Processes
According to the product technical data from Guoli Chemical, PEG400DL, with its hydrophilic-lipophilic balance (HLB value approximately 20) and excellent interfacial activity, has precise process applications in the following areas:
Detailed Application Industries and Processes
| Industry Field | Specific Application Process | Core Function |
| Cosmetics and Personal Care | Preparation of creams, lotions, shampoos, and shower gels | Solubilization, auxiliary emulsification, emollient, viscosity adjustment |
| Industrial Cleaners and Metalworking Fluids | Hard surface cleaning, cutting fluids, grinding fluids | Low-foam surfactant, lubrication, synergistic anti-rust |
| Textile and Leather Auxiliaries | Antistatic finishing, softening finishing, leveling process | Eliminate static electricity, improve hand feel, ensure dyeing uniformity |
| Pesticide Formulations | Preparation of water-based suspension concentrates, oil-in-water emulsions | Emulsify and disperse active ingredients, improve spreading and wetting of the spray solution |
| Coatings and Inks | Pigment grinding and dispersion, finished paint blending | Wet and disperse pigments, promote leveling, prevent flocculation |
Application Recommendations
- Recommended Dosage: When used as an emulsifier or solubilizer, the recommended addition amount is 1% - 5% of the total system weight (data based on Guoli Chemical product testing).
- Compatibility: This product is nonionic and has good compounding compatibility with anionic, cationic, and other nonionic surfactants, making it suitable for multi-formulation systems.
- Process Operation Key Points: Add during the mixing stage of oil and water phases. Utilizing the product's low-foam characteristic can avoid production issues caused by foam in subsequent processes, especially suitable for systems requiring vacuum degassing.
Precautions
- The product is not resistant to strong alkalis; it performs best under neutral to weak acid or weak alkali conditions.
- Cloudiness or solidification may occur at low temperatures, which is a normal physical phenomenon. After returning to room temperature, stir evenly before use; product performance will not be affected.
- The product is hygroscopic. After opening, it should be sealed and stored immediately to avoid prolonged contact with aqueous media.
