Ethanol
It´s presented as a colorless, flammable liquid with a boiling point of 78 °C.
Miscible with water in any proportion, the concentration of 95% by weight forms an azeotropic mixture.
Its chemical formula is CH3-CH2-OH, the main product of alcoholic beverages such as wine (about 13%), beer (5%) or liquor (up to 50%).
Apart from being used for culinary purposes (alcohol), ethanol is widely used in many industrial sectors and the pharmaceutical sector, as a carrier of some drugs and cosmetics (in the case of rubbing alcohol 70 ºGL and the development of air fresheners and perfumes ).
It is a good solvent and can be used as antifreeze. It is also a disinfectant. His greatest bactericidal potential is obtained at a concentration of approximately 70%.
