Should I buy 70% or 99% isopropyl alcohol IPA solution?
Your choice between 70% and 91% isopropyl alcohol depends on your intended use:
Choose 70% IPA isopropyl alcohol if: - Your main need is disinfection (e.g. cleaning skin before injections, sanitising household surfaces or disinfecting medical tools). It is more effective at killing bacteria and viruses due to its slower evaporation rate and better penetration of microbes. It is also more cost-effective for regular, large-scale use.
Choose 91% IPA isopropyl alcohol if: You need a balance between disinfection and light cleaning (e.g. sanitising electronic accessories such as phone cases, removing sticker residue or cleaning make-up tools). It evaporates faster than 70% IPA, leaving less residue while still providing strong disinfectant performance for non-critical surfaces.
Key Properties of Isopropyl Alcohol:
1. Volatility: IPA isopropyl alcohol evaporates readily at ambient temperatures. This rapid evaporation is advantageous in applications like electronics cleaning but can be a limiting factor for disinfection if contact times are not met.
2. Flammability: Isopropyl Alcohol is highly flammable. Solutions, especially those with higher alcohol concentrations, pose a fire risk and must be handled with appropriate precautions, away from ignition sources.
3. Solvent Power: It's an effective solvent for many oils, resins, and alkaloids, contributing to its use in cleaning solutions and certain extraction processes.
4. Antimicrobial Action: Its primary mechanism for disinfection is the denaturation of proteins and disruption of cell membranes of microorganisms, a process heavily influenced by water content.
