The usage method of C13 Alcohol Polyether E-1340 varies by application field. It is usually added directly to the formulation as an emulsifier, wetting/penetrating agent, or dispersant. The recommended dosage is generally 1% to 10% of the total formula weight, and the specific amount should be optimized through experimentation.

Detailed Description

C13 Alcohol Polyether E-1340 (Isomeric tridecanol polyoxyethylene (13) ether) is a nonionic surfactant with an HLB value of 13.5~14.5. It is easily soluble in water and appears as a colorless to slightly yellow transparent liquid at room temperature. Thanks to its excellent wetting, emulsifying, and dispersing properties, it is widely used in various industrial fields. The usage method generally follows the principle of direct addition and thorough mixing, but specific operational details vary depending on the application scenario.

In the textile printing and dyeing field, this product can be used as a scouring agent, penetrant, and leveling agent. It is usually added directly to the pretreatment or dyeing bath, utilizing its low-foaming and strong penetrating properties to help remove impurities from the fabric and promote uniform dye uptake, effectively preventing color spots and white cores. In industrial cleaning (such as hard surface cleaning and metal parts cleaning), this product can be compounded with alkaline additives, chelating agents, etc., leveraging its strong emulsifying and degreasing ability to break down heavy oil and grease. Due to its low-foaming characteristics, it is particularly suitable for high-pressure spraying and easy-rinsing cleaning systems.

In pesticide formulations and leather processing, this product is used as an efficient emulsifier and carrier. When preparing pesticide emulsifiable concentrates or emulsion concentrates, it can be mixed evenly with the oil-soluble active ingredient and then diluted with water to form a stable emulsion. In the leather degreasing process, it is added directly to the water bath to quickly penetrate and emulsify natural oils in the leather. When used as an emulsion stabilizer in emulsion polymerization, it should be dissolved in the water phase before the polymerization reaction to form a stable micelle environment, thereby precisely controlling the polymerization particle size and emulsion stability of monomers such as acrylates and styrene.

Application Recommendations

  • Textile Pretreatment\/Dyeing: Can be added directly to the bath at 0.5~2 g\/L together with alkali or dyes to effectively improve capillary effect and leveling.
  • Industrial Hard Surface Cleaners: It is recommended to compound with sodium alkylbenzene sulfonate, 6501, etc., at an addition level of 1%~5% to fully utilize its ability to emulsify and disperse oil and grease.
  • Pesticide Emulsifiable Concentrates\/Emulsion Concentrates: As the main emulsifier, the typical addition amount is 5%~15%, and compounding with nonionic\/anionic emulsifiers can provide a more stable emulsion system.
  • Leather Degreasing: Adding 0.5%~2% based on the weight of leather into the drum degreasing bath can significantly improve the removal rate of natural oils.
  • Waterborne Coatings\/Inks: Add 0.2%~1% (based on total formula weight) during the pigment dispersion stage to quickly wet the pigment and prevent flocculation.
  • Emulsion Polymerization: As the main emulsifier, the recommended dosage is 1%~5% of the total monomer amount, providing excellent micellar solubilization and particle size control capability.

Precautions

  • Safety Protection: This product causes skin irritation and may cause serious eye damage (H315, H318). Chemical safety goggles and chemical-resistant protective gloves (e.g., nitrile rubber gloves) must be worn during operation.
  • Dissolution Operation: Although this product is easily soluble in water, its viscosity increases at low temperatures. It is recommended to feed materials in an environment above 10°C and mix thoroughly. For high-concentration systems, it is advisable to pre-dilute with water or solvent before adding to the main reactor.
  • Storage Conditions: Store in a cool, dry, well-ventilated area, keep the container tightly closed, and control the storage temperature between 5°C and 40°C. Avoid freezing or prolonged exposure to high temperatures to prevent quality deterioration.
  • Usage Limits: The above dosage ranges are general recommendations. The final addition amount should be determined through gradient experiments based on the specific formulation system to ensure optimal performance and economy.
