Acetic acid, also known as ethanoic acid, is a liquid chemical compound that is colorless in nature. After formic acid, it is the second simplest carboxylic acid. Acetic acid is an important industrial chemical and chemical reagent, used in the production of chemical products, such as Vinyl acetate monomer (VAM), Purified Terephthalic Acid (PTA), synthetic fibre and fabrics, polyvinyl acetate for wood glue, cellulose acetate for photographic film, and more. It is widely used in various end-use industries, such as paints and coatings, construction, plastics, rubber, and pharmaceutical, among others.
Most acetic acid is made by methanol carbonylation, where carbon monoxide and methanol react to produce acetic acid. The compound is miscible with benzene, acetone, ethyl ether, and ethanol, and is soluble in carbon disulfide and carbon tetrachloride. This compound has been used for several years in the cosmetics industry as an oxidizing agent, removing impurities in colorants and binders. The compound has also been used to convert other organic materials into other compound materials such as acrylics, rubbers, polymers, and dyes. The compound has also found its use as an antiseptic and deodorizer.
Acetic acid, vinegar, and brown rice vinegar are used to control the pH of cosmetics and personal care products. Acetic acid is used as a stabilizer and solvent in cosmetic products. Other examples are lip balm, lip gloss, lipsticks, foundations, blush, skin lotions, eye shadows, eyeliners, mascara, shiners, and nail varnish. Acetic acid is known to lighten, whiten, soften, and brighten the complexion of human beings. In fact, cosmetic manufacturers have introduced several types of Acetic acid based beauty products, which include vinyl acetate monomer, acetylated lanolin alcohol, and pure vinyl.
Moreover, acetic acid is a two-carbon organic acid produced in wine during or after the fermentation period. It is used in the production of some citrus wines. It is added at the end of the fermentation process to give a sharp, bitter taste, reminiscent of black cherry or lemon. Acetic acid is also used as a preservative in many kinds of food, particularly in sea foods, but the practice has become more widespread in non-fermented foods. Furthermore, it is generally recognized as safe for use in foods if it is of "food-grade" and is used in accord with good manufacturing processes. However, excessive levels of the substance can be toxic. Vinegars with acetic acid as their primary ingredients are not toxic when taken properly.
Acetic acid, as scientifically identified, is a colorless, odorless liquid organic substance with the basic chemical formula CH₃COOH. The main substance in vinegar is acetic acid that help kill harmful bacteria or prevent them from multiplying. Moreover, acetic acid has antibacterial and antifungal properties. Industrially, acetic acid is used in the preparation of volatile organic esters, used as solvents for lacquers, paints, and resins; cellulose acetate, used to make photographic films and textiles; vinyl acetate, used in the production of plastics; and metal acetates, used in some printing processes. Biologically, it is an important metabolic intermediate and it occurs naturally in plant juices and in body fluids.
