Environmentally friendly penetrant JFC-M alcohol (chemical name: ethylene glycol monoethyl ether, alias 2-ethoxyethanol\/ethyl cellosolve, CAS No.: 5689-56-3), with molecular formula C₄H₁₀O₂, molecular weight 90.12, belongs to nonionic surfactants. The product appears as a colorless to light yellow transparent liquid, readily soluble in water, and remains stable in acids, alkalis, hard water, and electrolyte solutions.
The product has an HLB value ranging from 11.5 to 12.5, a cloud point of 85~95℃, and combines excellent penetrating, wetting, and washing functions. Its penetrating power is outstanding—at a concentration of 1g\/L in aqueous solution at 25℃, the standard canvas sinking method yields a penetration time of no more than 5 seconds, significantly improving process efficiency in textiles, leather, papermaking, etc. Its low foaming tendency facilitates easy rinsing, reducing water consumption and energy usage.
From a safety and environmental perspective, the product has an acute oral toxicity LD50>2000 mg\/kg (low toxicity), is non-irritating to skin and eyes, readily biodegradable (28-day degradation rate >60%), APEO-free, and complies with international environmental regulations.
