This acid is an important chemical reagent and industrial chemical useful for the production of various synthetic fibers and other polymeric materials. These polymers include polyethylene terephthalate, used mainly in soft drink bottles; cellulose acetate, used mainly for photographic film; and polyvinyl acetate, for wood glue.
In households, diluted acetic acid is often used in descaling agents. Skin sensitization to acetic acid is rare, but has occurred. It has been reported that in 12 workers exposed for two or more years to an average acetic acid airborne concentration of 51 ppm, there were symptoms of conjunctival irritation, upper respiratory tract irritation, and hyperkeratotic dermatitis.
Exposure to 50 ppm or more is intolerable to most persons and results in intensive tearing and irritation of the eyes, nose, and throat, with pharyngeal edema and chronic bronchitis.
Unacclimatized humans experience extreme eye and nasal irritation at concentrations in excess of 25 ppm, and conjunctivitis from concentrations below 10 ppm has been reported. In a study of 5 workers exposed for 7 to 12 years to concentrations of 80 to ppm at peaks, the principal findings were blackening and hyperkeratosis of the skin of the hands, conjunctivitis but no corneal damage , bronchitis and pharyngitis, and erosion of the exposed teeth incisors and canines.
It is unknown whether acetic acid could cause cancer in humans, but studies in animals and cell lines show no link to cancer or birth defects. The United Sates Food and Drug Administration FDA has affirmed that acetic acid is generally recognized as safe as a multipurpose food additive, as a substance migrating to food from cotton and cotton fabrics used in dry-food packaging, as a substance migrating to food from paper and paperboard products, and as a general purpose food additive for animal feed.

It commonly serves as a chemical reagent in laboratories, but also on a larger industrial scale. In chemical companies, acetic acid is used to make other chemicals. Acetic acid is used in the manufacture of plastic items such as bottles other synthetic materials. Ethanoic or acetic acid is used in making dyes, pigments, and paint and coating additives.
It is used in printing on fabric. It is a component of wood glue and other sealants. Acetic acid is also used as a cleaning and degreasing solvent. It can be used to etch inorganic films. Acetic acid is commonly used in photographic materials such as film and chemical solutions.
It is also used in the petroleum industry and is used to plate and treat surfaces, such as on cars. Acetic acid is also used in the production of pharmaceuticals.
In the food industry, acetic acid in lower concentrations is used as a food additive, flavoring and preservative. Acetic acid regulates food acidity. In the household, food acetic acid uses include pickling and the acid's presence in vinegar. Pickling vegetables and fruits with vinegar preserves them because acetic acid prevents bacterial growth. Diluted acetic acid is prevalent in some window cleaning sprays and other household cleaners.
Laundry and dishwashing detergents also often carry acetic acid. Acetic acid is a component of anti-freeze and de-icing agents, and it is used in pest-control agents like herbicides and insecticides.
It is a component of some car polishes. Even makeup and vitamins are often made with acetic acid! In medicine, there are interesting acetic acid uses, some of which have endured for centuries. Acetic acid is an ingredient of wart remover solutions. It can also be found in some eardrops. Acetic acid possesses both antifungal and antibacterial benefits. In lower concentrations, acetic acid has been used as a topical agent to treat wounds, especially burn wounds. Acetic acid helped prevent the spread of the bubonic plague.
It was even crucial in helping the injured during the Civil War. Dilute acetic acid is effective at fighting some resistant strains of bacteria. It has also been proven to be an effective treatment against pernicious fungal infections. In particular, sufferers of the disease mucormycosis, an often-fatal disease caused by fungi in the Mucorales order, may benefit from low-dose applications of acetic acid.
Expensive and invasive treatments have historically been used to fight this kind of infection. This fungal infection does not respond to other kinds of acid such as lactic and hydrochloric acid. But at a 0.
