Sodium Dehydroacetate
What is Sodium Dehydroacetate?
Sodium dehydroacetate is the sodium salt of dehydroacetic acid, a synthetic compound featuring a pyrone ring structure designed for antimicrobial properties. Originating from chemical synthesis in the early 20th century, it serves as a preservative in the cosmetics industry, particularly in skincare, cleansers, and emulsions. It works by interfering with fungal enzyme activity and cell division, effectively controlling molds and yeasts that threaten product stability. This targeted fungicidal action makes it suitable for aqueous formulations vulnerable to microbial spoilage. As a water-soluble white powder, it integrates seamlessly into creams, lotions, and serums at effective levels. Cosmetic regulators evaluate it based on extensive testing for compatibility in rinse-off and leave-on products, ensuring it maintains formulation integrity without compromising user experience.
