Sodium dehydroacetate

Description:
Sodium dehydroacetate is the sodium salt of dehydroacetic acid, a compound commonly used as a preservative and antimicrobial agent in various food and cosmetic products. It appears as a white to off-white crystalline powder and is soluble in water, making it effective in aqueous formulations. The substance is known for its ability to inhibit the growth of bacteria, yeast, and molds, which contributes to its role in extending the shelf life of products. Sodium dehydroacetate is generally recognized as safe (GRAS) when used within specified limits, and it is often favored for its low toxicity compared to other preservatives. Additionally, it has a mild, slightly sweet taste, which can be advantageous in food applications. Its stability under various pH conditions allows for versatility in formulation, although it is most effective in slightly acidic environments. Overall, sodium dehydroacetate is valued for its preservative properties, safety profile, and compatibility with a range of products.
