Zinc undecylenate is widely used in the treatment of fungal infections, particularly those affecting the skin. It is a key ingredient in antifungal creams, powders, and ointments, effectively combating conditions like athlete's foot, ringworm, and other dermatophyte infections. Its antifungal properties help inhibit the growth of fungi, providing relief from itching, irritation, and discomfort. Additionally, it is used in over-the-counter products for its mild and soothing effect on the skin, making it suitable for sensitive areas. Zinc undecylenate is also incorporated into foot care products to prevent and treat fungal growth in moist environments, such as between toes. Its dual role as an antifungal agent and skin protectant makes it a valuable component in dermatological formulations.
