Medical alcohol, also known as ethanol alcohol, has the chemical formula C2H6O or C2H5OH. Alcohol 70 degrees is prepared in solution form, bottled with different volumes, suitable for many uses, bottles with content: 30ml, 50ml, 60ml, 100ml, 500ml,.
Medical alcohol can be mixed with different concentrations from 60% to 90% can be used to disinfect. However, according to recommendations, the 70% alcohol form is the best antibacterial ability.
The ratio 7:3 of medical alcohol 70 degrees has been studied to show optimal antiseptic ability, when this content is enough to keep the alcohol on the skin for a long time to disinfect. Alcohol 90 degrees due to the low percentage of water, so it evaporates quickly. Although it has a higher alcohol concentration, 90-degree alcohol is not as good at disinfecting as 70% alcohol and easily causes skin irritation and burning.
The mechanism of action of antibacterial alcohol is to denature proteins of microorganisms and kill bacteria, fungi and viruses, but it has no effect on spores. Although higher concentrations of alcohol also denature bacterial proteins, it accidentally creates an outer coating that protects bacteria from the effects of alcohol. On the other hand, a higher alcohol concentration will be more volatile, so it also reduces the effectiveness of the disinfectant somewhat.
According to doctors, most of the fast hand sanitizers on the market today use alcohol with a concentration of 70% - 75%. For adults, 70 degrees of medical alcohol can be used to quickly disinfect hands when needed. Children under 2 months old should not use alcohol-based hand sanitizers containing Chlorhexidine.
