70% isopropol alcohol is a better disinfectant. The presence of water is a crucial factor in destroying or inhibiting the growth of pathogenic microorganisms with isopropyl alcohol. Water acts as a catalyst and plays a key role in denaturing the proteins of cell membranes.
70% solutions penetrate the cell wall more completely, coagulate all proteins, and the microorganism dies. Extra water content slows evaporation, increasing surface contact time and enhancing effectiveness. Isopropyl alcohol over 91% coagulates proteins instantly, and causes a protective layer to be created which protects other proteins from further coagulation
