FAQ

What are the main differences between the 99.5% and 99.9% purity grades of Isopropyl Alcohol?

The 99.5% grade is suitable for most pharmaceutical, cosmetic, and industrial applications including general cleaning, solvent use, and disinfectant formulations, offering cost-effectiveness. The 99.9% ultra-high purity grade provides higher purity specifically engineered for sensitive applications such as electronics cleaning (circuit boards, optical components), HPLC and analytical laboratory use, and precision manufacturing where absolute minimal residue and strict impurity control are critical .

What is the recommended concentration for hand sanitizer and disinfectant applications?

For optimal germicidal efficacy, Isopropyl Alcohol should be diluted with distilled water to approximately 70% concentration. This concentration provides optimal cell wall penetration and protein denaturation for effective disinfection. The World Health Organization (WHO) recommends formulations containing 70-75% IPA for hand sanitizers and surface disinfection .

Why is Isopropyl Alcohol preferred for electronics cleaning?

IPA is preferred for electronics cleaning due to its rapid evaporation rate, complete residue-free drying, excellent solvency for fluxes, oils, and contaminants, and non-corrosive nature toward electronic components. It effectively cleans circuit boards, PCB, magnetic tape heads, CD/DVD laser lenses, sensors, cameras, keyboards, and other precision components without leaving residues that could affect performance .
