The full chemical name of isooctanol penetrant OE-35 is isooctanol polyoxyethylene ether, also known as 2-ethylhexanol polyoxyethylene ether and polyoxyethylene isooctyl ether. Its molecular structure is C8H17O(C2H4O)nH, where the ethylene oxide addition number n=35, and the molecular weight is approximately 1670. This product is formed by connecting the hydrophobic isooctanol (2-ethylhexanol) carbon chain with the hydrophilic polyoxyethylene chain segment through an ether bond, belonging to the typical nonionic surfactant structure.
In terms of composition, the effective active ingredient content of Guoli Chemical's OE-35 is ≥99%, free alcohol content ≤1%, water content ≤0.5%, making it a high-purity penetrant product. Its appearance is a colorless to slightly yellow transparent liquid, easily soluble in water, with an HLB value of about 13.5 and a cloud point >100°C, indicating excellent hydrophilicity and high-temperature stability.
