What solution must be readily available during a manicure?

The requirement for having a readily available solution during a manicure emphasizes the importance of maintaining clean and sanitary conditions. A 70% alcohol solution is widely recognized as an effective disinfectant. At this concentration, alcohol is able to penetrate cell walls and effectively kill bacteria and viruses. The presence of water in the solution helps to slow down the evaporation of alcohol, allowing it to stay on the surface longer, thereby enhancing its disinfecting capability.

In a manicure setting, using 70% alcohol ensures that tools and surfaces are adequately disinfected between clients, helping to prevent the spread of infections and ensuring client safety. This is particularly vital in environments where personal grooming is performed, as the risk of skin contact with potentially contaminated surfaces is higher.

Higher concentrations of alcohol, like 90%, can evaporate too quickly to be fully effective as a disinfectant, while lower concentrations, such as 50%, may not be sufficient for effective germicidal action. Isopropyl alcohol, while also a disinfectant, does not specify the concentration and thus makes it less ideal in this context. Therefore, 70% alcohol stands out as the optimal choice for disinfection during manicures.
