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 FieldSpecific Application ProcessCore Function
Cosmetics and Personal CarePreparation of creams, lotions, shampoos, and shower gelsSolubilization, auxiliary emulsification, emollient, viscosity adjustment
Industrial Cleaners and Metalworking FluidsHard surface cleaning, cutting fluids, grinding fluidsLow-foam surfactant, lubrication, synergistic anti-rust
Textile and Leather AuxiliariesAntistatic finishing, softening finishing, leveling processEliminate static electricity, improve hand feel, ensure dyeing uniformity
Pesticide FormulationsPreparation of water-based suspension concentrates, oil-in-water emulsionsEmulsify and disperse active ingredients, improve spreading and wetting of the spray solution
Coatings and InksPigment grinding and dispersion, finished paint blendingWet 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.
