PEG600MO (Polyethylene Glycol 600 Monooleate) is usually a light yellow to yellow liquid or paste at room temperature, with good fluidity and operability. As a nonionic O/W emulsifier, its HLB value is in the medium to high range (about 13-14), which means it is particularly suitable for emulsifying and dispersing oily components in the aqueous phase system. When using, the following three mainstream addition methods can be selected according to specific process conditions:
Direct Addition Method: For aqueous systems (such as industrial cleaners, pesticide emulsions), PEG600MO can be directly added to the aqueous phase under stirring conditions and stirred evenly. Due to its good water dispersibility, it generally dissolves without heating. Premixing Method: For formulations containing oil phase components (such as creams, lotions, metalworking fluid concentrates), it is recommended to first mix PEG600MO evenly with oily components (such as mineral oil, vegetable oil, active oils, etc.), then slowly add to the water phase under stirring for emulsification, which can obtain a finer and more stable emulsion. Heating and Melting Method: In low-temperature environments, the product may be paste-like. It is recommended to preheat the packaging drum in a 30–40°C water bath, or use a heating jacket. After the product regains fluidity, take it out for use. Do not heat directly with open flame.

Personal Care and Cosmetics: Used as an emulsifier for O/W creams, lotions, cleansing oils, and facial cleansers. The recommended dosage is 1%–5% of the total formula weight. Mix PEG600MO with the oil phase (such as vegetable oils, ester oils, silicone oils, etc.) and heat to 60–75°C, while heating the water phase to a similar temperature. Then, under high-shear stirring, slowly add the water phase to the oil phase (or vice versa), homogenize for 3–5 minutes, and cool to obtain a stable emulsion. It can also be used as a solubilizer for flavors and essential oils, with a recommended dosage of 2–5 times the amount of the solubilizate.
Metalworking Fluids: Used as an emulsifier and lubricating component in cutting fluids and grinding fluids. The recommended addition amount in the concentrate formula is 5%–15%. Mix PEG600MO evenly with base oil, rust inhibitors, extreme pressure additives, and other oily components. Dilute with water to a working fluid concentration of 5%–10% before use to obtain a stable emulsified processing fluid.
Textile Industry: Used as an antistatic agent and soft finishing agent. The recommended working fluid concentration is 0.5%–3% (based on fabric weight). Use the padding or impregnation method for finishing treatment. Treat at room temperature or 40–50°C for 15–30 minutes, then dry to impart a soft and smooth feel to the fabric and effectively reduce static accumulation.
Pesticide Formulations: Used in pesticide emulsifiable concentrates or emulsion in water formulations. The recommended dosage is 3%–10% of the total formulation weight. After mixing evenly with the pesticide technical material and solvent, slowly add water under stirring for phase inversion emulsification to obtain a stable emulsion formulation, significantly improving the wetting and spreading ability of the liquid on the target surface.
Industrial Cleaners: As a nonionic surfactant component, the recommended addition amount is 2%–8% of the total formula weight. It can be used in combination with other nonionic or anionic surfactants, and has significant emulsifying and anti-redeposition effects on mineral oil, animal and vegetable oil stains.
Pharmaceutical Field: Used as a drug solubilizer to improve the dispersion state of poorly soluble drugs. The recommended dosage should be determined by experiments based on the drug properties and preparation type, usually 1–10 times the amount of the drug. It can be added directly under stirring or dispersed after co-melting with the drug.
