Environmentally friendly penetrant JFC (CAS No.: 68439-50-9) has the full chemical name fatty alcohol polyoxyethylene ether, with the molecular formula C12-14H25-29O(C2H4O)nH (n≈9), and a molecular weight of approximately 580. This product appears as a colorless to slightly yellow transparent liquid. It is a nonionic surfactant, free of free phosphoric acid and tertiary amine components, with an active content ≥99% and free alcohol content controlled within 1.0%.
In terms of surface activity parameters, the HLB value of 11~13 endows it with excellent wetting and emulsifying balance; cloud point 40~50°C, surface tension of 0.1% aqueous solution at room temperature 25~30 mN\/m, critical micelle concentration (CMC) between 0.01% and 0.1%, enabling the product to significantly reduce system surface tension even at low concentrations and exert superior penetration—standard canvas sedimentation method penetration ≤5 seconds. Meanwhile, the pH values of 1% and 5% aqueous solutions are both stable in the neutral range of 5.0~7.0, ensuring good compatibility with various formulation systems.
The product exhibits excellent chemical stability, resistant to acids and alkalis, especially maintaining performance stability in 1%~5% NaOH solution; freezing point below -10°C and flash point above 150°C, making it a non-flammable liquid. It also features low viscosity (kinematic viscosity 50~150 mm²\/s) and low foam characteristics, facilitating pump delivery and industrial application. It is widely used in textile pretreatment, industrial cleaning, paper deinking, pesticide emulsification, and wetting and dispersion in water-based coatings.
