Definition of "isopropyl alcohol" by Spec Services:
« Back to Glossary Index Isopropyl alcohol (IPA), also known as isopropanol or 2-propanol, is a clear, colorless, flammable liquid with a strong odor. It is a type of alcohol commonly used as a solvent, disinfectant, and cleaning agent due to its ability to dissolve oils, grease, and other contaminants. Its chemical formula is C₃H₈O or C3H7OH.
Key Characteristics:
- Evaporation: It evaporates quickly, leaving minimal residue, which makes it ideal for cleaning delicate surfaces like electronics.
- Antimicrobial Properties: It is effective at killing bacteria, viruses, and fungi, making it a common ingredient in hand sanitizers and disinfectants.
- Concentration: Typically available in concentrations ranging from 70% to 99% in water. A 70% solution is often preferred for disinfection because the water content slows evaporation, allowing the alcohol to penetrate cell walls more effectively.
Common Uses:
- Cleaning Electronics: Safely removes dust, oils, and residues from circuit boards, screens, and other sensitive components.
- Disinfection: Used in healthcare settings to sterilize surfaces, medical instruments, and skin before injections.
- Household Cleaning: Removes sticky residues, ink stains, and smudges from glass, mirrors, and other surfaces.
- Industrial Applications: Acts as a solvent in manufacturing processes, including paints, coatings, and adhesives.
Safety Note: Isopropyl alcohol is highly flammable and should be used in well-ventilated areas away from open flames or heat sources. Prolonged skin exposure or inhalation of fumes can cause irritation or health issues, so proper precautions, such as wearing gloves and working in a ventilated space, are recommended.
