Water is more than 70 percent of the body's tissues.
70% alcohol signifies the amount the alcohol present in 100 ml of the solution. Considering the solvent to be water, 70% alcohol contains 70ml alcohol and 30ml water. Thus, the total comes out to 70 + 30 = 100ml. That's what the "%" signifies - (out of 100!)
Feces is typically composed of about 75% water. The remaining 25% consists of solid material, such as undigested food, bacteria, and waste products.
70 percent ethanol is more effective at killing microbes than 100 percent ethanol. This is because the addition of water helps to denature proteins and disrupt cell membranes in the microbes, leading to better penetration and more efficient sterilization. Additionally, 70 percent ethanol is less volatile and evaporates more slowly, allowing for longer contact time with the microbes.
First of all, because technological limits mean that we can only get alcohol at a purity of about 90%. 90% alcohol is also far more expensive than 70%, so it is more cost effective to use 70%. Ignoring all of that, the main reason is that 70% alcohol works just fine and sterilizes object very well.70%alcohol is the efficient concentration to denature the protein.
