PEG200MO (polyethylene glycol 200 monooleate), as a non-ionic surfactant, has flexible and diverse usage methods. In practice, the direct addition method is most common: add the product directly into the oil phase or water phase, stir evenly, then mix with the other phase for emulsification. If the formulation contains multiple surfactants, it is recommended to preheat PEG200MO with the oil-soluble components in the formulation to 40~60°C and mix evenly, then slowly add the water phase under stirring to obtain a fine and stable emulsion system.
For scenarios requiring solubilization or dispersion (such as pesticide microemulsions, metalworking fluids), the premixing method can be used: first thoroughly mix PEG200MO with the oily active substance to be dispersed, if necessary, with brief high-shear stirring to allow the surfactant to fully coat the oil droplets, then dilute to the desired concentration. For powder dispersion applications, it is recommended to first dissolve the product in the liquid medium, then add the powder for grinding or high-speed dispersion to fully utilize its wetting and anti-settling ability.
PEG200MO is non-ionic and has good compatibility with anionic, cationic and other non-ionic surfactants. In actual formulations, it is often used synergistically with Span series, Tween series or other non-ionic additives, adjusting the HLB value to suit different oil phase systems. When compounding, it is recommended to conduct small-scale tests first to determine the optimal ratio before scale-up production.
| Application Field | Recommended Addition Method | Reference Dosage (of total formulation) | Key Operation Points |
|---|---|---|---|
| Creams/Emulsions (Cosmetics) | Preheat and premix with oil phase components | 1%~5% | Heat oil phase to 50~65°C, slowly add to water phase under stirring, homogenize and emulsify for 3-5 minutes |
| Cleansing Oils/Body Washes | Directly add to oil phase or finished product | 2%~8% | Mix thoroughly; can be combined with other non-ionic surfactants to adjust skin feel |
| Metalworking Fluids (Emulsified Cutting Fluids) | Premix with base oil | 3%~10% | Blend with base oil, rust inhibitor, etc., then dilute with water to working fluid |
| Pesticide Emulsion in Water (EW)/Microemulsion (ME) | Premix with pesticide technical and solvent | 4%~10% | High-shear emulsification to ensure uniform dispersion of active ingredients; dilution stability must be verified experimentally |
| Textile Spinning Oils/Leveling Agents | Directly add to the formulation system | 1%~5% | Used in combination with other lubricants and antistatic agents to adjust oil pickup rate |
Note: The above dosages are general industry recommended ranges. The specific optimal dosage should be determined through small-scale tests based on the actual formulation system and process conditions. This product database does not provide precise formulation recommendation ratios; the above data are given based on application experience.
