In chemistry, an alcohol is any organic compound in which a hydroxyl group (-OH) is bound to a carbon atom of an alkyl or substituted alkyl group.
Of those, ethanol (C2H5OH) is the type of alcohol found in alcoholic beverages, and in common speech the word alcohol means, specifically, ethanol. The most common method to produce alcohol is by fermentation of sugars (eg the sugar of the grapes is transformed by fermentation into ethanol to make wine).
Ethanol is geneally avoided in cosmetic formulations. It is not a harmful ingredient but if it is used in high percentage can dry the skin as it forms azeotropes with water.
In our formulations is used in After Shave Balm for sanitation of the skin. It can also be found in traces in a few other formulations. In this case it is carried through other ingredients of the cosmetic formulation.
