Emulsifier A-105 is widely used in six major industries: pesticide formulations, textile dyeing and finishing, industrial cleaning, leather processing, metalworking fluids, and emulsion polymerization.

Detailed Description

Emulsifier A-105 (nonylphenol polyoxyethylene (10) ether, CAS: 9004-96-0) is an excellent nonionic surfactant. The synergistic effect of ether bonds and hydroxyl groups in its molecular structure endows the product with high-efficiency emulsifying, wetting, dispersing, and detergency capabilities. It exhibits good tolerance to acidic/alkaline media and hard water environments and can be used in combination with anionic, cationic, and other nonionic surfactants.

Industry and Process Applications

IndustryProcess/ApplicationFunction Description
Pesticide formulationsPreparation of emulsifiable concentrates, oil-in-water emulsions, microemulsionsPromote the formation of stable emulsions of oily active ingredients with water, enhance spreading and penetration of the spray solution, ensure storage stability
Textile dyeing and finishingLeveling agent, scouring agentRetard dye uptake for uniform color; remove oils and stains from fiber surfaces
Industrial cleaningFormulation of hard surface cleanersStrongly emulsify and disperse mineral oils, animal and vegetable oils, prevent redeposition
Leather processingDegreasing of raw hidesDeeply penetrate leather fibers to efficiently emulsify natural fats, gentle action without damaging the hide
Metalworking fluidsPreparation of cutting fluids, grinding fluidsCombine base oil with water to form stable working fluids, providing lubrication, cooling, and anti-rust properties
Emulsion polymerizationPolymerization of monomers such as acrylates, styreneForm and stabilize latex particles, control particle size distribution, improve mechanical stability and storage stability of emulsion

Application Recommendations

When used as the main emulsifier in pesticide formulations, adjust the dosage according to the oil phase type; generally add 5% to 15% of the total formulation. In metalworking fluids, it can be compounded with other additives, with a recommended dosage of 3% to 10%. The optimal ratio should be verified through small-scale tests in actual use. This product is resistant to acid, alkali, and hard water, and can maintain stable performance under a wide pH range and high hardness water conditions.

Precautions

  • Toxic to aquatic organisms (fish LC₅₀ 96h: 1-10 mg/L, daphnia EC₅₀ 48h: 1-10 mg/L). Do not discharge into water bodies.
  • Slow biodegradation rate. Waste must be disposed of properly in accordance with local environmental regulations.
  • Risk of severe eye irritation or damage. Chemical safety goggles must be worn during operation.
  • Skin contact may cause mild irritation. Protective gloves are recommended.
  • Recommended storage temperature not exceeding 40°C. Keep away from heat sources and open flames.
