dehydroacetic

Dehydroacetic, also known as DHA, is a chemical compound with the formula C8H8O4. It is a white, crystalline solid that is odorless and has a slightly acidic taste. Dehydroacetic is soluble in water and many organic solvents. It is a derivative of pyrone, a six-membered heterocyclic organic compound containing one oxygen atom.

Dehydroacetic is primarily used as a preservative in cosmetics and personal care products. Its antimicrobial properties help to prevent the growth of bacteria, yeast, and mold, thereby extending the shelf life of these products. It is effective against a broad spectrum of microorganisms and is often used in combination with other preservatives to enhance its efficacy. In cosmetics, it can be found in products such as lotions, creams, shampoos, and makeup.

Beyond its use in cosmetics, dehydroacetic also finds applications as a plasticizer and in some food packaging materials. Its ability to inhibit microbial growth makes it useful in preventing spoilage. It is generally considered safe for use in approved concentrations in cosmetic products by regulatory bodies such as the U.S. Food and Drug Administration (FDA) and the European Commission. However, as with any chemical, potential for skin irritation or allergic reactions exists in sensitive individuals.
