Description
A colorless, corrosive liquid with a strong Vinegar smell. It is widely used in industry as a solvent and reagent. Pure acetic acid, (>99.7%) is called glacial acetic acid. Acetic acid is the active ingredient in vinegar in concentrations of about 5%, giving it an acidic flavor and a pungent odor. Acetic acid is found naturally in many fruits, plants, and wood. It is deleterious to metals and may be harmful to oil paintings, watercolors, drawings and sketches. Acetic acid is used in the manufacture of acetates and plastics, printing Calico and dyeing Silk, in pesticides, photographic chemicals, pharmaceuticals, as an etching agent, bleach, and stain remover, and as a preservative in food processing. Acetic acid can evolve from wood and wood products, degraded cellulose acetate, polyvinyl acetate adhesives, acetoxy-curing silicone sealants, vinegar-based cleaning solutions and many types of fresh coating, such as oil-based paints (Tétreault 2017).
