Used primarily as an antifungal and antibacterial agent in personal care products, especially in anti-dandruff shampoos. It helps control the growth of Malassezia yeast on the scalp, which is linked to dandruff and seborrheic dermatitis. Also found in body washes and facial cleansers for its ability to reduce odor-causing bacteria and maintain skin clarity. Its mild action and low irritation potential make it suitable for long-term use in cosmetic formulations.
