Dehydroacetic acid is an organic compound. The compound is classified as a pyrone derivative and is used mostly as a fungicide and bactericide. The sodium salt, sodium dehydroacetate, is often used in place of dehydroacetic acid because of its greater solubility in water. It is prepared by the base-catalysed dimerization of diketene.
Industrially, it is also used as a plasticizer in synthetic resins. It is used to reduce pickle bloating as a preservative for squash and strawberries. Also used in antienzyme toothpastes. Clinical tests show little to no evidence regarding the ingredient's toxicity and potential for irritation. When used as a food additive, dehydroacetic acid is referred to using the International Numbering System for Food Additives or E number 265.
