Description

Zinc Undecylenate is the zinc salt of undecylenic acid, a well-established compound with significant antifungal and bacteriostatic properties. Its primary commercial value lies in its efficacy as a safe and active ingredient in topical formulations for skin and foot care. This makes it a critical raw material for manufacturers in the pharmaceutical and personal care industries, particularly for products like antifungal powders, creams, and medicated soaps. Its stability and compatibility with various excipients ensure reliable performance in finished consumer goods.

Application

• Antifungal Pharmaceuticals: A key active ingredient in over-the-counter (OTC) and prescription topical medications for treating athlete's foot (tinea pedis), ringworm, and other cutaneous fungal infections.
• Personal Care Products: Used in medicated foot powders, antifungal creams, ointments, and deodorant soaps for its drying and antimicrobial action.
• Cosmetic Preservation: Acts as a mild preservative in cosmetic formulations to inhibit microbial growth, extending product shelf life.
• Textile & Polymer Additive: Incorporated into fibers, plastics, and coatings to impart antifungal properties, preventing mold and mildew growth.
• Veterinary Applications: Formulated into topical treatments for fungal skin conditions in animals.
• Industrial Biocide: Used in certain industrial fluids and materials where fungal inhibition is required.

Quality Control

Our Zinc Undecylenate is manufactured under strict quality management systems. It can be produced to meet various pharmacopoeial standards, including USP-NF and Ph. Eur. monographs, ensuring suitability for pharmaceutical applications. Each batch undergoes rigorous analytical testing for identity, purity, and heavy metal content. A comprehensive Certificate of Analysis (COA) is provided with every shipment to guarantee batch-to-batch consistency and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect quality and flow properties.
