Chemical Information
FooDB NameAcetic acid
DescriptionHas been used as a food preservative since antiquity. It is used in - and contributes to - the flavour of pickles, sauces, mayonnaise and salad dressings. Acts synergistically with lactic and sorbic acid, and is more effective against yeasts and bacteria than against moulds. It is used in food processing as a flavour enhancer, flavouring agent, pH control agent, pickling agent, solvent and formulation aid Acetic acid is an organic compound with the chemical formula CH3COOH. It is a colourless liquid that when undiluted is also called glacial acetic acid. As the main component of vinegar, it has a distinctive sour taste and pungent smell. Acetic acid is found in many foods, some of which are garden rhubarb, wild celery, pear, and ginger.

Acidulant64047 A substance that increases acidity, commonly used as a food additive. Biologically, it helps maintain pH balance. Therapeutically, acidulants have applications in managing digestive issues and nutrient absorption. Key medical uses include treating conditions like gastroesophageal reflux disease (GERD) and enhancing mineral absorption, particularly in patients with malabsorption disorders.DUKE
Anti bacterial33282 An agent that inhibits the growth of or destroys bacteria, playing a crucial role in preventing and treating infections. Therapeutically, it is used to combat bacterial infections, with key medical applications including treating pneumonia, tuberculosis, and skin infections, as well as preventing surgical site infections and sepsis.DUKE
Anti otitic52217 An agent that reduces inflammation and infection in the ear, commonly used to treat otitis media (middle ear infection) and other ear disorders, promoting hearing health and alleviating symptoms such as pain and discomfort.DUKE
Anti-salmonella33282 An agent that targets and eliminates Salmonella bacteria, reducing the risk of food poisoning and gastrointestinal infections. Therapeutically, it is used to treat salmonellosis, a disease caused by Salmonella infection, and to prevent outbreaks in high-risk individuals, such as those with weakened immune systems.DUKE
Anti-vaginitic52217 An agent that prevents or treats vaginal infections, reducing inflammation and promoting healthy vaginal flora. Therapeutically, it is used to manage vaginitis, relieving symptoms such as itching, burning, and discharge, and is commonly applied in gynecology to treat bacterial, fungal, or parasitic infections.DUKE
Expectorant52217 An agent that thins and loosens mucus, making it easier to cough up, reducing congestion. It aids in clearing respiratory tract secretions, commonly used to relieve coughs, colds, and bronchitis, promoting easier breathing and soothing irritated airways.DUKE
Fungicide24127 An agent that kills or inhibits the growth of fungi, playing a biological role in preventing fungal infections. Therapeutically, it is used to treat fungal diseases, with key medical applications including athlete's foot, ringworm, and candidiasis, as well as agricultural uses to protect crops from fungal damage.DUKE
KeratitigenicA factor that promotes corneal wound healing and regeneration, playing a biological role in tissue repair. Therapeutically, it has applications in ophthalmology, particularly in treating corneal injuries and ulcers, and may be used to enhance graft survival in corneal transplants, promoting healthy tissue growth and vision restoration.DUKE
Mucolytic77034 An agent that breaks down mucus, reducing its viscosity and facilitating clearance. It plays a biological role in maintaining respiratory tract health. Therapeutically, mucolytics are used to manage respiratory conditions, such as chronic bronchitis, asthma, and cystic fibrosis, by loosening and clearing excess mucus.DUKE
OsteolyticAn agent that dissolves bone, particularly by removing calcium, playing a role in bone remodeling. Therapeutically, osteolytic agents are used to treat conditions like hypercalcemia and bone metastases. Medically, they are applied in managing diseases such as osteoporosis, Paget's disease, and certain cancers.DUKE
Perfumery48318 The art of creating fragrances, playing a biological role in emotional and sensory stimulation. Therapeutically, perfumery has applications in aromatherapy, reducing stress and anxiety. Key medical uses include mood enhancement, pain management, and promoting relaxation, with certain scents exhibiting anti-anxiety and anti-depressant properties.DUKE
Pesticide25944 An agent that kills or repels pests, playing a biological role in controlling insect, weed, and fungal populations. Therapeutically, pesticides have limited applications, but some are used to treat ectoparasitic infestations, such as lice and scabies. Key medical uses include topical treatments for head lice and scabies, highlighting their role in managing parasitic infections.DUKE
ProtisticideAn agent that kills protozoans, used as a herbicide or in therapeutic applications to treat protozoan infections, with key medical uses including managing parasitic diseases and infections.DUKE
SpermicideA contraceptive substance that destroys sperm, inserted vaginally prior to intercourse to prevent pregnancy, serving as a non-hormonal birth control method.DUKE
UlcerogenicAn agent that causes the production of ulcers, often used to study gastrointestinal disease mechanisms. Its biological role involves disrupting mucosal defense, leading to ulcer formation. Therapeutically, understanding ulcerogenic agents informs the development of anti-ulcer medications. Key medical uses include researching gastric ulcer pathogenesis and testing potential treatments for ulcer prevention and healing.DUKE
VerrucolyticAn agent that treats verruca, a contagious foot wart, by breaking down the lesion, promoting healing, and reducing pain. Therapeutically, it's used to manage plantar warts, with key medical applications in podiatry and dermatology.DUKE
