Used primarily as an antifungal agent in anti-dandruff shampoos and scalp treatments. It helps control flaking, itching, and scaling of the scalp by inhibiting the growth of Malassezia yeast, a common contributor to dandruff. Its effectiveness, low irritation potential, and stability in formulations make it a popular choice in over-the-counter dermatological products. Also found in some cosmetic products designed to prevent microbial contamination.
