What are the main components of octadecylamine polyoxyethylene ether AC-1810?

The main component of octadecylamine polyoxyethylene ether AC-1810 is octadecylamine polyoxyethylene (10) ether, i.e., the addition polymer of octadecyl primary amine (stearylamine) with approximately 10 moles of ethylene oxide (EO).

Detailed Description

The core component of AC-1810 is octadecylamine polyoxyethylene (10) ether (CAS No.: 26635-75-6), whose structure consists of two parts: the hydrophobic end is an octadecyl straight-chain alkyl group (derived from octadecylamine/stearylamine), and the hydrophilic end is a polyoxyethylene (PEO) chain segment with an average polymerization degree of about 10. This molecular structure of "long-chain alkyl + medium-length EO chain" imparts unique amphiphilic properties to the product.

From a chemical perspective, this product belongs to nonionic surfactants, but the tertiary amine nitrogen atom in the molecule gives it weak cationic characteristics in aqueous solution or under acidic conditions. The effective active content is usually above 98% (based on solid content), and the appearance ranges from light yellow liquid to paste, with different physical forms depending on temperature changes.

Under similar nomenclature, this product is also known as PEG-10 stearylamine, stearylamine polyoxyethylene (10) ether, polyoxyethylene (10) stearylamine, etc. It belongs to the fatty amine polyoxyethylene ether (FAE) class of surfactants and exhibits good stability against acid, alkali, and hard water.

Technical Parameters

Application Suggestions

Based on its molecular structure of octadecylamine + 10EO, AC-1810 is suitable for the following application scenarios:

• Textile Dyeing and Printing: Used as a high-efficiency leveling agent and antistatic finishing agent, utilizing its weak cationic properties to enhance adsorption onto fibers.
• Pesticide Formulations: Used as an emulsifier to effectively disperse oil phase components in emulsifiable concentrates and oil-in-water emulsions, improving the spreading and penetration of the liquid preparation.
• Metalworking Fluids: Exhibits corrosion inhibition function, forming a protective film on metal surfaces.
• Daily Chemicals: Serves as an emulsifying and solubilizing component in creams, lotions, and other products.
• Petroleum Industry: Used as a component of demulsifiers to promote oil-water separation.
• Plastic Industry: Applied as an internal antistatic agent to reduce surface resistance of products.

Precautions

• This product is classified as skin irritant (H315) and serious eye irritant (H319). Protective gloves, safety goggles, and protective clothing must be worn during handling.
• Storage temperature is recommended to be controlled between 5 and 35°C. Avoid freezing or overheating, and keep containers tightly sealed.
• Keep away from strong oxidizing agents and strong acids; avoid mixed storage.
• In case of skin or eye contact, immediately flush with plenty of water for at least 15 minutes and seek medical attention promptly.
