MOA-23 appears as a white to slightly yellow waxy solid at room temperature (melting point approximately 40~45°C) and is easily soluble in water. It is recommended to preheat it to 45~50°C to melt it into a flowable liquid, then slowly add it to hot water at 50~80°C while stirring until completely dissolved to form a clear or slightly turbid solution. It can also be directly added to the hot water phase of the formulation and heated together for dissolution. This product has certain hygroscopicity. After opening, it should be sealed promptly to avoid moisture absorption and caking.
Textile Dyeing Leveling Agent: When used as a high-temperature and high-pressure dyeing leveling agent, the recommended dosage is 1~3 times the weight of the dye (adjusted according to the dye type and depth of dyeing). First dissolve it in hot water at 60~80°C in a dissolving tank, then add it to the dye bath. The cloud point of MOA-23 is above 100°C (1% aqueous solution), enabling it to withstand high-temperature dyeing processes. Coupled with its excellent dispersibility, it effectively prevents dye aggregation that causes color spots and uneven coloring.
Industrial Cleaning and Metal Degreasing: In heavy-duty industrial cleaning formulations, the recommended dosage is 2%~8% of the total formulation. Combine MOA-23 with alkaline additives (such as sodium hydroxide, sodium carbonate) and chelating agents. Utilizing its strong alkali resistance and emulsifying degreasing ability, it can quickly remove heavy oil stains and carbon deposits from metal surfaces. Suitable for immersion, spraying, or ultrasonic cleaning processes.
Cosmetic O/W Emulsifier: MOA-23 has an HLB value of approximately 16.5, making it a typical oil-in-water emulsifier. The recommended dosage is 2%~5% of the oil phase weight. Procedure: Add MOA-23 to the water phase and heat to 70~75°C to dissolve. Heat the oil phase separately to the same temperature. Then slowly add the oil phase to the water phase under homogenization stirring, homogenize for 3~5 minutes, and then cool. The resulting emulsion is fine and stable with a mild skin feel. It can also be used as a solubilizer for fragrances and essential oils.
Household Detergents: In laundry liquid formulations, the recommended dosage is 1%~5%. It can be well compounded with nonionic, anionic, and amphoteric surfactants, providing low-foaming washing performance and anti-redeposition effects, especially suitable for machine washing formulations.
Emulsifier for Emulsion Polymerization: The recommended dosage is 1%~3% of the total monomer weight. Dissolve MOA-23 in deionized water to form the water phase, then add the monomer under stirring for pre-emulsification. This yields a polymer emulsion with uniform particle size and good storage stability, suitable for systems such as acrylate and styrene-acrylic.
Leather Degreasing and Paper Deinking: For leather degreasing, the recommended dosage is 0.5%~2% (based on raw hide weight). For paper deinking, the recommended dosage is 0.1%~0.5% (based on oven-dry pulp weight). The specific dosage should be adjusted according to the fat content of the raw material or the amount of ink.
