Dehydroacetic Acid (DHA) is a low-toxic, high-efficiency, broad-spectrum antimicrobial agent, mainly used for mildew and corrosion prevention of food, coatings, oils, leather products, feed, packaging materials and cosmetics. Its molecular formula is C8H8O4, molecular weight is 168.15, and its properties are colorless to white needle-shaped or plate-shaped crystals or white crystalline powder, odorless, slightly soluble in ethanol and cold water, and its aqueous solution is weakly acidic, with a melting point of 108-111°C and a boiling point of 269.9°C.

Chemical properties
Dehydroacetic acid has a certain antibacterial effect under acidic and alkaline conditions, especially the strongest inhibitory effect on mold. It is easily soluble in aqueous solution of fixed alkali, difficult to dissolve in water, soluble in benzene, ether, acetone and hot ethanol.

Application fields
Dehydroacetic acid and its sodium salt (sodium dehydroacetate) are widely used in food, beverages, pharmaceutical preparations and cosmetics.
