MOA-9 (AEO-9) is a nonionic surfactant with a high HLB value (13.6), easily soluble in water, and has good compatibility with anionic, cationic, and other nonionic surfactants. When using, it is usually directly added to the water phase or oil phase and stirred evenly. If it is in paste form (low temperature environment), it is recommended to heat it to about 25~30°C to restore fluidity before use, for accurate measurement and rapid dispersion.
This product has good chemical stability in dilute acid and alkali solutions and hard water. The usage temperature should not exceed its cloud point range (55~65°C, 1% aqueous solution) to ensure optimal wetting, penetration, and emulsification effects. In compounded systems, MOA-9 can replace part of the anionic surfactants to improve the overall hard water resistance of the formulation.
Since the specific dosage is affected by multiple factors such as other components in the formulation, target process requirements, and cost control, the following recommended dosage is an industry general empirical range. In practical applications, it is recommended to determine the optimal economical dosage through gradient experiments.

Depending on the application field, the recommended dosage of MOA-9 is as follows (based on total formulation weight, industry empirical values):
| Application Field | Recommended Dosage (wt%) | Usage Instructions |
|---|---|---|
| Industrial Hard Surface Cleaning/Degreasing Agent | 3%~10% | Compound with anionic surfactants to improve hard water resistance and degreasing power. |
| Household Liquid Detergent (Dishware/Laundry) | 2%~8% | Low foaming and easy to rinse; can partially replace LAS/AES to reduce gel zone risk. |
| Textile Dyeing and Printing Pretreatment Scouring Agent | 1~5 g/L (Working Solution Concentration) | Acts as a wetting agent and scouring agent component to quickly wet fibers and remove impurities. |
| Textile Leveling Agent | 0.5~2 g/L (Dye Bath Concentration) | Promotes uniform dye uptake and prevents color spots and blotches. |
| Leather Degreasing/Fatting Agent | 5%~15% | Emulsifies natural oils, assists degreasing, and improves leather softness. |
| Pesticide Emulsifiable Concentrate (EC) Emulsifier | 5%~15% (Based on Total EC Weight) | Used in combination with anionic emulsifiers (e.g., calcium salts) to ensure dilution stability. |
| Metalworking Fluid/Emulsifying Oil | 3%~8% | Acts as an emulsifying dispersant to stabilize mineral oil or synthetic ester emulsion systems. |
| Paper Deinking Agent | 0.1%~0.5% (Based on Oven-Dried Pulp) | Effectively strips ink particles and prevents redeposition. |
| Cosmetic Creams/Lotions | 1%~4% | Used as O/W emulsifier or fragrance solubilizer; wide compatibility and low irritation. |
Note: The above dosages are industry general empirical recommendations. The database does not contain precise formulation data for each field. The actual optimal dosage should be determined through formulation compatibility tests and performance tests.
