Dehydroacetic Acid
What is Dehydroacetic Acid?
Dehydroacetic acid is a synthetic organic compound, chemically classified as a heterocyclic beta-keto acid with antifungal and antibacterial properties. Derived through chemical synthesis, it appears as a white to pale yellow crystalline powder. In cosmetics, it serves primarily as a preservative in water-containing products like creams, lotions, shampoos, and makeup. It functions by penetrating microbial cell walls, disrupting metabolic processes, and preventing the proliferation of bacteria, yeasts, and molds. This helps maintain product integrity without significantly altering texture or scent. Typically used at low concentrations, it complements other preservatives for broad-spectrum protection. Regulatory bodies recognize its efficacy and safety profile in rinse-off and leave-on formulations, supporting its widespread inclusion in personal care items.
