PEG200MO (Polyethylene Glycol 200 Monooleate) is a light yellow to yellow transparent liquid with an HLB value of approximately 8. It is a strongly lipophilic nonionic surfactant, especially suitable for preparing O/W (oil-in-water) emulsion systems. The product has an active content ≥99.0%, is easily dispersible in water, and exhibits good formulation compatibility. It can be flexibly compounded with anionic, cationic, and other nonionic surfactants.
In practical use, PEG200MO is typically used as an emulsifier, wetting agent, or dispersant. It can be directly added to the oil phase and dissolved by heating (recommended heating to 40~60°C), then mixed with the water phase for homogenization emulsification. Alternatively, it can be pre-mixed uniformly with the oil phase components and then slowly added to the water phase under stirring to form an emulsion. For systems requiring high-shear dispersion (e.g., pesticide microemulsions, metalworking fluids), high-shear or homogenization equipment is recommended to fully leverage its emulsifying and dispersing performance.
The Guoli Chemical database does not contain precise recommended dosage parameters for each specific application field. The following recommended dosages are based on the product's HLB value (8) and typical industry application experiences. It is recommended that users conduct gradient experiments in actual formulations to determine the optimal dosage.

1. Cosmetics and Personal Care Products (Creams, Lotions, Makeup Removers, Body Washes)
Recommended Dosage: 1%~5% (based on total formulation weight). As an O/W emulsifier, mix PEG200MO uniformly with oil phase components (e.g., oils, silicone oils) at 40~60°C, then homogenize with the water phase. To enhance emulsion stability, it is recommended to combine with a co-emulsifier having a higher HLB value (e.g., PEG-40 Hydrogenated Castor Oil).
2. Metalworking Fluids (Emulsified Cutting Fluids, Rust Inhibitors)
Recommended Dosage: 5%~15% (based on total concentrate weight). PEG200MO provides stable lubricating emulsions, reduces tool wear, and improves rust inhibition. It is typically formulated with base oils, rust inhibitors, and extreme pressure additives. High-shear emulsification equipment is recommended to ensure uniform droplet size.
3. Textile Auxiliaries (Spinning Oils, Leveling Agents)
Recommended Dosage: 1%~3% (based on total working solution weight). Used to improve fiber spinnability and lubricity, and promote uniform dye dispersion and retardation. It can be directly added to the spinning oil or leveling agent formulation and stirred evenly before use.
4. Pesticide Formulations (Emulsion in Water EW, Microemulsion ME)
Recommended Dosage: 3%~8% (based on total formulation weight). As a key emulsifying adjuvant, premix PEG200MO with the pesticide technical and solvent, then add to water with shear emulsification. This effectively improves the dilution stability of the formulation and the wetting and spreading of the spray liquid on plant leaves.
