Unformatted text preview: http://www.madsci.org/posts/archives/jan2001/978900651.Ch.r.html Ethyl acetate, C4H8O2 also known as ethyl ethanoate, is an ester made by reacting a carboxylic acid with an alcohol. Carboxylic acid has a COOH functional group and alcohols have the OH functional group, which both react to form an ester and water. Ethyl acetate, found in nail polish, is organic, insoluble in water and used as a solvent. Ethyl ethanoate dries fairly fast and is also used in nail polish remover. Organic polymer (hardened polish on a nail) can be dissolved by an organic solvent (nail polish remover) http://emedicine.medscape.com/article/1067468-overview Nitrocellulose, the most commonly used primary film-forming agent in nail polish, produces a shiny, tough, nontoxic film that adheres well to the nail plate. The film is somewhat oxygen permeable, allowing gas exchange between the atmosphere and the nail plate to ensure nail plate health. Resins and plasticizers are then added to increase the flexibility of the film, minimizing chipping and peeling. All of these ingredients are added to increase the flexibility of the film, minimizing chipping and peeling....
