Compared with the same series products of Guoli Chemical (AC-1810, AC-1812, AC-1815, AC-1820, AC-1860), the core differentiation advantage of Octadecylamine Polyoxyethylene Ether AC-1830 lies in the unique performance balance brought by the 30 ethylene oxide (EO) adduct number. Compared with low EO number products (e.g., AC-1810 with 10EO, AC-1812 with 12EO), AC-1830 has an HLB value as high as 16~17, with significantly enhanced hydrophilicity, making it more soluble and dispersible in water, thus becoming an efficient O/W emulsifier; while compared with high EO number AC-1860 (60EO), AC-1830 retains better interfacial adsorption capacity and lower foaming property, performing better in scenarios requiring low foam characteristics such as industrial cleaning. It can be said that 30EO is the "golden ratio" of hydrophilicity and interfacial activity in the octadecylamine polyoxyethylene ether series.
From the perspective of technical parameters, AC-1830 has many advantages that are difficult to achieve simultaneously in similar products: cloud point exceeding 100°C (1% aqueous solution), meaning no phase separation occurs under high-temperature process conditions, especially suitable for high-temperature leveling in textiles and metal processing and other high-temperature conditions; surface tension about 32 mN/m, with critical micelle concentration (CMC) only 0.02-0.05 g/L, indicating that it can exert excellent wetting and emulsifying effects even at very low dosages; tertiary amine content ≥95% ensures consistency and stability of product performance; and low foam characteristic makes it easier to rinse in industrial cleaning formulations, reducing water usage and residue risk.
In terms of compounding compatibility, AC-1830, with its predominantly nonionic and weakly cationic dual ionic characteristics, can be widely compounded with anionic, cationic, and nonionic surfactants, which is difficult for pure nonionic or pure cationic surfactants to achieve. Compared with commonly available fatty alcohol polyoxyethylene ethers (AEO series), the nitrogen-containing structure of AC-1830 imparts unique antistatic properties and fiber affinity, making it significantly more effective in textile softening and antistatic applications than ordinary nonionic surfactants.
