What is Dehydroacetic acid
Dehydroacetic acid is a preservative that is used in a variety of personal care and cosmetic products, including shampoos, conditioners, lotions, creams, and other skin and hair care products.
It is used to help prevent the growth of bacteria, fungi, and other microorganisms that can cause spoilage or deterioration of the product. Dehydroacetic acid is a synthetic compound that is generally considered to be safe and effective when used in small amounts as directed.
It is also approved for use as a food preservative in some countries but NOT Singapore. However, as with any chemical, it is important to use it responsibly and to follow the instructions for use provided by the manufacturer.
