About Isopropyl Alcohol 70% USP Grade

Isopropyl Alcohol (IPA) at the 70% concentration is the most common concentration sold in stores as rubbing alcohol. This product contains 70% isopropyl alcohol 30% distilled water. The combination of alcohol and water makes this an ideal solution for cleaning against microbial bacteria, fungi, and viruses. The water acts as a catalyst for denaturing proteins and penetrating cell membranes, because of the higher water content it doesn’t vaporize as readily as higher concentrations giving it more time to make contact with the surface.

Examples of when Isopropyl Alcohol 70% is the preferred concentration.

  • IPA 70is the most effective concentration for cleaning against bacteria, fungi and viruses and it is more effective than 99.8% or 91% IPA.
  • IPA 70% is used widely for medicinal purposes as a disinfectant of surfaces and skin.
  • IPA 70% is used in the food industry to sanitize reactors, vats, and other equipment.
