Emulsifier MOA-3B (fatty alcohol polyoxyethylene (3) ether), with its excellent emulsifying, wetting, dispersing, and solubilizing properties, is mainly used in six major industry sectors: pesticide formulations, chemical fiber industry, textile printing and dyeing, industrial mold release, emulsion polymerization, and oil-soluble systems.

Detailed Description

Emulsifier MOA-3B is a high-performance nonionic surfactant produced by Haian Guoli Chemical Co., Ltd., with the chemical name fatty alcohol polyoxyethylene (3) ether (C12~14). It has a moderate hydrophilic-lipophilic balance (HLB) value, making it particularly suitable for preparing water-in-oil emulsions. This product maintains good chemical stability in both acidic and alkaline environments, exhibits excellent tolerance to hard water, and has high active matter content, ensuring stable and reliable performance.

Thanks to its outstanding emulsifying ability, excellent wetting and dispersing properties, and efficient solubilizing capacity, emulsifier MOA-3B plays a key role in multiple industrial fields. It can effectively reduce interfacial tension, promote liquid spreading on solid surfaces, and provide significant dispersion and stabilization effects for solid particles. It can also significantly enhance the solubility of poorly soluble substances in the system, offering broad scope for formulation design.

Additionally, the product has a near-neutral pH, making it gentle on substrates and operators. Its flash point is above 150°C, classifying it as a non-flammable liquid, which ensures high safety in routine industrial applications. Note that the product is classified as skin irritation category 2 and serious eye damage/eye irritation category 2, so appropriate protective equipment should be worn during handling.

Application Fields and Process Details

Application Industry Specific Process/Use Function Description
Pesticide Formulations Pesticide emulsifiable concentrate emulsifier As the core emulsifying component in pesticide emulsifiable concentrate formulations, it enables the pesticide active ingredient to spontaneously emulsify rapidly upon dilution, forming a stable oil-in-water emulsion, ensuring uniform spray and improving field efficacy.
Chemical Fiber Industry Chemical fiber oil component Functions as an emulsifier, smoothing agent, and binder in synthetic fiber spinning oils, reducing friction between fibers and metal parts, lowering static buildup, and improving the cohesion and spinnability of the tow.
Textile Printing and Dyeing Leveling agent, antistatic agent Used in fabric pretreatment and dyeing processes to promote uniform dye uptake and prevent uneven dyeing and spots; also imparts antistatic properties to fiber surfaces, enhancing fabric hand feel and processing smoothness.
Industrial Mold Release Mold release lubricant Applied to the mold surface during polymer material forming to form a release film, effectively reducing adhesion between the product and the mold, achieving clean release, and also providing lubrication to protect the mold.
Emulsion Polymerization Latex polymerization stabilizer Provides micelle nucleation sites and stabilizes latex particles during emulsion polymerization, preventing gelation or demulsification, controlling particle size distribution, and ensuring storage stability of the latex product.
Oil-Soluble Systems Dispersant Promotes uniform dispersion of solid particles, pigments, or active ingredients in oil-based or solvent-based formulations, preventing agglomeration and sedimentation, maintaining system homogeneity, and improving product performance and shelf life.

Application Recommendations

The most prominent feature of emulsifier MOA-3B is its moderate HLB value, making it particularly outstanding in water-in-oil (W/O) emulsion systems. For users who need to prepare pesticide emulsifiable concentrates, oil-based dispersion systems, or mold release agents, this product is an ideal choice. Formulators are advised to determine the optimal dosage through experiments based on the specific oil phase and emulsification requirements to achieve a balance between emulsion stability and economic efficiency.

In chemical fiber oil and textile auxiliary applications, MOA-3B can be used in combination with other surfactants to synergistically enhance multiple functions such as lubrication, antistatic properties, and bundling. In emulsion polymerization processes, it is recommended to optimize the dosage and addition method of the emulsifier based on the monomer system and target particle size distribution.

Precautions

  • The product is classified as skin irritation category 2 and serious eye damage/eye irritation category 2. During operation, wear chemical safety goggles, chemical-resistant gloves, and appropriate protective clothing.
  • Recommended storage temperature should be maintained between 5°C and 40°C, avoiding freezing or overheating, and keep containers tightly sealed.
  • Flash point (closed cup) is above 150°C. Although not classified as a flammable liquid, it should still be stored away from heat sources, sparks, and open flames.
  • Prevent large-scale leakage into sewers, surface water, or groundwater, as it may be harmful to aquatic organisms.
  • If skin contact occurs, wash immediately with plenty of soap and water; if it enters the eyes, rinse carefully with water for at least 15 minutes and seek medical attention promptly.
  • For detailed safety information, refer to the product Safety Data Sheet (SDS).
