The main component of Dodecylamine Polyoxyethylene Ether AC-1215 is the addition polymer of dodecylamine (laurylamine) and ethylene oxide (approximately 15 mol), with the chemical name Polyoxyethylene (15) Laurylamine.

Detailed Description

Dodecylamine Polyoxyethylene Ether AC-1215 is a nonionic surfactant produced by the addition polymerization reaction of fatty amine (dodecylamine/laurylamine) and ethylene oxide (EO). Its molecular structure can be represented as: C₁₂H₂₅N(CH₂CH₂O)ₙH, where n represents the average addition moles of ethylene oxide, approximately 15 for this product.

The molecular structure of this product contains both amine functional groups (—NH—) and polyoxyethylene ether chain segments (—CH₂CH₂O—). This unique amphiphilic structure endows the product with the ability to exhibit both nonionic and cationic characteristics, existing as a nonionic form in neutral or alkaline media, while in acidic media the amine groups undergo protonation, causing the product to behave as a cationic surfactant.

The product appears as a colorless to pale yellow transparent liquid (above 25°C), and may be in paste or solid state at low temperatures. The CAS number is 26635-75-6, and it belongs to the typical alkylamine polyoxyethylene ether nonionic surfactant class.
