How to use PEG400MO, Polyethylene Glycol 400 Monooleate? What is the recommended dosage?

The recommended dosage of PEG400MO is usually 1%~10% of the total formulation, which needs to be determined through experiments based on the application system and formulation requirements.

Detailed Description

PEG400MO (Polyethylene Glycol 400 Monooleate) is a non-ionic surfactant with an HLB value of approximately 11.5. At room temperature, it appears as a light yellow to amber transparent liquid, readily soluble in water and polar solvents such as ethanol and acetone. During use, it can be added directly to the water phase or oil phase, or pre-mixed with the oil phase before emulsification. If the formulation contains multiple surfactants, it is recommended to compound it with other non-ionic or anionic components, adjusting the overall HLB value to achieve optimal emulsification performance. If the product becomes viscous or solidifies due to low temperature, it can be preheated under mild conditions of 25~40°C and stirred evenly before use, without affecting product performance.

In the emulsification process, it is recommended to first dissolve this product in the oil phase and then slowly add it to the water phase (or use the phase inversion method), combined with appropriate high-speed stirring or homogenization equipment, to obtain an emulsion with finer particle size and better stability. When used as a solubilizer, mix this product evenly with the substance to be solubilized, then slowly add water for dilution, which helps form a transparent or translucent microemulsion system.

Due to its low foaming, hard water resistance, and mildness to the skin, this product has strong applicability in cosmetics, textile auxiliaries, metalworking fluids, and other fields. It is recommended to conduct small-scale trials before formal production to optimize the optimal addition ratio and process conditions for specific systems.

Application Recommendations

Based on the product database and application experience of Guoli Chemical, the recommended dosage ranges for various fields are as follows (as a percentage of total formulation mass, subject to adjustment based on specific systems):

• Cosmetic Creams/Emulsions: 2%~5%, used as O/W emulsifier and emollient, imparting a silky skin feel to the product.
• Cleansing Oils/Facial Cleansers: 3%~8%, used as solubilizer and emollient cleansing component, promoting dissolution and rinsing of oil and makeup.
• Spinning Oils/Textile Softeners: 5%~10%, providing lubrication, antistatic, and softening effects.
• Metalworking Fluids (Emulsifiable Type): 3%~8%, as emulsification and lubrication component, promoting stable dispersion of oil phase in water.
• Pesticide Emulsifiable Concentrates/Microemulsions: 5%~10%, used to emulsify active ingredients, improving spreading and penetration of the pesticide solution.
• Coatings and Inks: 0.5%~2% (based on pigment weight), as wetting and dispersing agent to promote uniform pigment dispersion.
• Industrial Metal Cleaners: 2%~6%, enhancing emulsification and stripping ability for mineral oils, animal and vegetable fats.
• Leather Fatliquoring Agents: 3%~8%, imparting a soft and full hand feel to the finished leather.

Precautions

• The actual dosage should be determined through experiments to meet the stability, emulsifying power, and performance requirements of the specific formulation.
• Low-temperature environments may cause the product to solidify. Before use, gently heat to 25~40°C and stir evenly; quality is not affected.
• Avoid contact or storage with strong oxidizing agents (such as peroxides, concentrated nitric acid, etc.) to prevent adverse reactions.
• The product has certain hygroscopicity. After opening, reseal tightly and store in a cool, dry place (5~40°C), away from heat sources and open flames.
• It is recommended to wear safety goggles and impermeable gloves during operation to prevent accidental splashes into the eyes. In case of eye contact, rinse thoroughly with clean water for at least 15 minutes.
