PEG400DO, Polyethylene Glycol 400 Dioleate is mainly used in which industries and processes?

PEG400DO (Polyethylene Glycol 400 Dioleate) is widely used in industries such as textiles, industrial lubrication, metalworking, personal care, and agricultural chemicals, where it plays a core role as a non-ionic surfactant in key processes like emulsification, dispersion, wetting, and solubilization.

Detailed Description

PEG400DO (Polyethylene Glycol 400 Dioleate, CAS No. 9004-96-0) is a high-performance non-ionic surfactant that appears as a pale yellow to amber liquid. With its balanced hydrophilic-lipophilic properties, this product exhibits good tolerance to acidic and alkaline environments as well as hard water conditions. It also offers flexible compatibility with anionic, cationic, and other non-ionic systems, making it outstanding in a variety of industrial and consumer product formulations.

Its core functions cover multiple dimensions including emulsification, dispersion, wetting, and solubilization, making it an indispensable key component in many formulations. Its low toxicity and easy biodegradability also meet the modern industry's requirements for environmental protection and sustainable development.

Main Application Industries and Processes

1. Textile Industry — Spin Finish and Finishing
Used as a key component in spin finish for synthetic fibers, providing lubricity and antistatic ability to prevent fiber damage during drawing and winding, ensuring smooth processing and improving the finished hand feel. It also provides smoothness and emulsion stability in finishing processes, reducing friction damage to fibers.

2. Industrial Lubrication — Water-soluble Cutting Fluids and Hydraulic Fluids
Used in formulating water-soluble cutting fluids, hydraulic fluids, and extreme pressure lubricants as an efficient emulsifier and rust inhibitor. It helps stably disperse the oil phase in the aqueous phase, extending fluid service life, enhancing cooling and boundary lubrication performance, and improving boundary lubrication under extreme pressure conditions.

3. Metalworking Fluids — Turning, Milling, Grinding, and Stamping
Functions as an emulsifier and wetting agent in various metalworking processes, promoting the formation of stable oil-in-water emulsions, reducing tool wear, improving machining accuracy and workpiece surface finish, while enhancing emulsion system stability and synergistic rust prevention.

4. Personal Care Products — Facial Cleansers, Shower Gels, Makeup Removers, Shampoos
As a mild emulsifying and emollient ingredient, it effectively removes dirt while keeping skin moisturized, avoiding excessive degreasing, and imparting a silky after-wash feel. Suitable for product formulations such as facial cleansers, shower gels, makeup removers, and shampoos.

5. Agrochemical Formulations — Emulsifiable Concentrates (EC), Oil-in-Water Emulsions (EW), Microemulsions (ME)
Used in pesticide formulation to enhance the dispersion stability of active ingredients and their wetting and spreading ability on target surfaces, increasing penetration, thereby improving efficacy and utilization, and enhancing the uniform dispersion of active ingredients in EC and EW formulations.

6. Other Applications
It can also be used as a pigment dispersant, ink additive, and industrial cleaning agent component, demonstrating its multifunctional surfactant advantages.

Application Recommendations

In various application fields, the recommended usage of PEG400DO varies depending on the process:

• Textile Spin Finish: Used as a key formulation component in combination with other lubricants and antistatic agents; the optimal addition ratio should be determined through experiments.
• Metalworking Fluids: Used as a primary or secondary emulsifier, compatible with rust inhibitors and extreme pressure additives.
• Personal Care Products: Used as a mild emulsifying and emollient ingredient in rinse-off products such as facial cleansers and shower gels; skin feel tests are recommended during formulation development.
• Agrochemical Formulations: When used in emulsifiable concentrate and oil-in-water emulsion formulations, the dosage should be adjusted based on the properties of the active ingredient to achieve optimal dispersion stability.

Precautions

• Avoid contact with skin and eyes during operation; avoid inhaling its vapors or mists.
• Thoroughly wash after handling; it is recommended to wear protective gloves, protective clothing, and eye/face protection.
• If it enters the eyes, rinse carefully with water for several minutes; if wearing contact lenses, remove them before rinsing; if eye irritation persists, seek medical attention.
• May cause harmful effects to aquatic organisms; avoid direct discharge into water bodies. However, the product is readily biodegradable and has a relatively low overall environmental impact.
