PEG200MO (Polyethylene Glycol 200 Monooleate) is mainly applied in four major industries: personal care and cosmetics, textile industry, metalworking fluids, and pesticide formulations. In various formulations, it plays key roles as an emulsifier, dispersant, wetting agent, and solubilizer.

Detailed Description

PEG200MO is a nonionic surfactant produced by esterification of polyethylene glycol with natural oleic acid. It appears as a light yellow to yellow viscous liquid. Due to its excellent emulsifying ability, superior wetting and dispersing properties, outstanding chemical stability, and wide formulation compatibility, this product is widely used in multiple industrial fields.

In the personal care and cosmetics industry, PEG200MO is primarily used as an emulsifier in formulations such as creams, lotions, cleansing oils, and body washes. It effectively reduces the interfacial tension between oil and water, forming a stable and fine O/W emulsion system, giving the product a delicate texture and comfortable skin feel, while also helping to evenly distribute active ingredients. Due to its natural fatty acid origin, it has low irritation to skin and mucous membranes, making it very suitable for personal care and cosmetic formulation design.

In the industrial sector, PEG200MO also plays an irreplaceable role. In the textile industry, it is used as an important component in spinning oils and leveling agents; in metalworking fluids, it is a key component in emulsified cutting fluids and rust inhibitors; in pesticide formulations, it helps to uniformly disperse and solubilize active ingredients in emulsion concentrates (EW) and microemulsions (ME). Its nonionic nature allows it to be well combined with anionic, cationic, and other nonionic surfactants, flexibly meeting the needs of multi-component systems.

Detailed Industry Applications and Processes

Application Industry Specific Process/Product Function/Role Process Effect
Personal Care & Cosmetics Creams, lotions, cleansing oils, body washes O/W Emulsifier, Emollient Forms fine and stable emulsions, enhances moisturizing performance and skin feel
Textile Industry Spinning oils, leveling agents Lubricant, Dispersant, Retarding agent Reduces fiber friction coefficient, promotes uniform dye dispersion, improves textile processing efficiency and fabric quality
Metalworking Fluids Emulsified cutting fluids, rust inhibitors Emulsion stabilizer, Anti-rust component Provides stable lubricating emulsion, enhances anti-rust protection, reduces tool wear, improves machining precision and surface finish
Pesticide Formulations Emulsion concentrates (EW), Microemulsions (ME) Emulsifier, Dispersant, Solubilizer Promotes uniform dispersion of pesticide active ingredients, improves dilution stability, enhances wetting and spreading on plant leaves, increases efficacy utilization

Application Recommendations

In actual formulation design, it is recommended to reasonably adjust the dosage of PEG200MO based on the HLB value requirements of the target system. Due to its nonionic nature, PEG200MO can be flexibly combined with anionic, cationic, and other nonionic surfactants to achieve synergistic effects. For O/W emulsion systems, it can be used as a primary or auxiliary emulsifier to obtain good results.

When used in textile oils, it is recommended to combine with other lubricating components; for pesticide EW and ME formulations, compatibility screening should be carried out based on the characteristics of the active ingredients to ensure thermal and cold storage stability of the formulation.

Precautions

  • This product has an open cup flash point above 200°C and is not classified as a flammable liquid, but it is still recommended to store away from open flames and heat sources.
  • It has some hygroscopicity, so prolonged exposure to high humidity environments should be avoided, and the container should be kept tightly sealed during storage.
  • Recommended storage temperature is 5°C to 35°C; avoid prolonged exposure to extreme heat or freezing conditions to prevent phase separation or performance changes.
  • It is resistant to acids, alkalis, and hard water, maintaining stable performance over a wide pH range, making it suitable for various complex formulations.
  • It is recommended to wear chemical protective gloves and safety goggles during operation to avoid prolonged skin contact or eye splashes.
  • Recommended shelf life is at least 12 months from the date of production (under recommended storage conditions, following the first-in-first-out principle).
