MOA-23 (Laureth-23) is a highly polymerized nonionic fatty alcohol polyoxyethylene ether surfactant with an HLB value of about 16 to 17, appearing as a white waxy solid. Its core functions include excellent emulsifying ability, outstanding wetting and dispersing properties, as well as strong resistance to acids, alkalis, and hard water. It has good compatibility with anionic, cationic, and amphoteric surfactants.
This product is used as a leveling agent and dispersant in textile printing and dyeing to prevent dye aggregation, suitable for high-temperature and high-pressure dyeing processes; in industrial cleaning, it serves as a core component of metal degreasers, rapidly stripping heavy oil and carbon deposits; in household detergents, it provides emulsification, decontamination, and anti-redeposition properties; in cosmetics, it functions as an O/W emulsifier and solubilizer; in leather processing, it is used for raw hide degreasing; in the paper industry, it is used for waste paper deinking; in emulsion polymerization, it provides stable emulsification for acrylic ester, styrene-acrylic, and other systems.
| Industry | Specific Process/Use | Functional Role |
|---|---|---|
| Textile Printing and Dyeing | High-temperature and high-pressure dyeing, fabric scouring, wool degreasing | Leveling agent, dispersant, scouring agent |
| Industrial Cleaning | Hard surface cleaning, metal degreasing | Core emulsifying and degreasing component |
| Household Washing | Liquid laundry detergent, laundry powder formulations | Nonionic surfactant, decontamination and anti-redeposition |
| Cosmetics and Personal Care | O/W creams and lotions, fragrance solubilization | Emulsifier, solubilizer |
| Leather Processing | Raw hide degreasing, wet processing penetration | Degreasing agent, wetting and penetrating agent |
| Papermaking Industry | Waste paper recycling and deinking | Active ingredient of deinking agent |
| Emulsion Polymerization | Acrylic ester/styrene-acrylic emulsion systems | Polymerization emulsifier |
MOA-23, due to its high cloud point, is particularly suitable for high-temperature operating environments (e.g., high-temperature and high-pressure dyeing). Its high HLB value (16 to 17) makes it the preferred choice for oil-in-water (O/W) emulsification systems. If stronger penetration is required in the formulation, it can be compounded with lower-polymerization-degree AEO series.
