The usage method of Octadecylamine Polyoxyethylene Ether AC-1830 needs to be flexibly adjusted according to the specific application field, with the core focus on mastering the three major steps: dissolution, compounding, and dosage control.

Detailed Description

AC-1830 is a light yellow to yellow paste or solid at room temperature (melting point approx. 20-30°C). It is recommended to preheat and melt it with warm or hot water (40-60°C) before stirring evenly and adding to the batch. This product is easily soluble in water and organic solvents, with an HLB value as high as 16~17 and strong hydrophilicity. It can be directly dissolved in the aqueous phase to prepare a working solution. In formulation systems, it is often used as an auxiliary emulsifier, antistatic agent, or corrosion inhibitor component. It has good compounding compatibility with anionic, cationic, and nonionic surfactants and can be flexibly compounded as needed.

In textile printing and dyeing, when used as a leveling agent, the recommended dosage is 0.5~2 g/L (relative to the working solution), and it can be directly added to the dye bath for circulating operation. When used for antistatic finishing of synthetic fibers, the impregnation or padding process can be adopted, with a recommended working solution concentration of 1~5 g/L. In pesticide formulations, as a nonionic emulsifier, it is compounded with pesticide active ingredients, solvents, and anionic emulsifiers. It generally accounts for 2~8% of the total formulation. When preparing emulsions, it can be directly added to the oil phase, mixed evenly, and then emulsified in water.

In metalworking fluids, as a corrosion inhibitor and lubricant component, the recommended addition amount is 0.5~3% of the formulation, which can be directly added to the mother liquor and stirred to dissolve. In household fabric softeners, the recommended dosage is 1~5%. Better results are achieved when used in combination with cationic surfactants. In industrial cleaning formulations, as a wetting and penetrating agent, the recommended addition amount is 0.5~3%, which is compounded with alkaline auxiliaries and other surfactants, especially suitable for low-foam, easy-rinse cleaning systems.

Application Suggestions

For different application fields, the recommended dosage and incorporation method of AC-1830 are as follows (the data comes from application experience recommended values; the specific dosage needs to be confirmed through actual formulation tests):

Application Field Functional Role Recommended Dosage Method of Addition
Textile Printing and Dyeing (Leveling) Leveling Agent 0.5~2 g/L (Working Solution) Directly add to dye bath
Textile Printing and Dyeing (Antistatic) Antistatic Finishing Agent 1~5 g/L (Working Solution) Impregnation or padding process
Pesticide Formulations Nonionic Emulsifier 2~8% of total formulation First dissolve in oil phase, then emulsify in water
Metalworking Fluids Corrosion Inhibitor/Lubricant 0.5~3% of formulation Directly add to mother liquor and stir to dissolve
Household Fabric Softener Antistatic/Softening Agent 1~5% of formulation Compound with cationic and other components
Industrial Cleaning Agents Wetting and Penetrating Agent 0.5~3% of formulation Compound with alkaline auxiliaries and other surfactants

Precautions

  • Dissolution Operation: The product is hygroscopic. Seal immediately after use. If it is a paste solid, preheat and soften it in a 40-60°C water bath, then stir to dissolve in water. Avoid direct high-temperature heating to prevent localized overheating and decomposition.
  • Compounding Compatibility: It has good compatibility with various surfactants, but it is recommended to control the pH value of the formulation system within 6.0~8.0 for optimal results. Prolonged strong acidic or alkaline environments may affect product stability.
  • Safety Protection: Wear protective gloves and goggles during operation to avoid direct contact with eyes and skin. In case of accidental contact, rinse immediately with plenty of water. The flash point of the product is >200°C, and it is classified as non-hazardous, but it should still be kept away from fire sources and high temperatures.
  • Storage Suggestions: Storage temperature ≤40°C. Avoid freezing and direct sunlight. Keep the container tightly sealed. Seal immediately after use to prevent moisture absorption.
