Zinc Undecylenate

Zinc undecylenate is an organometallic salt formed from zinc and undecylenic acid, a naturally occurring fatty acid. It functions as an antimicrobial agent in skincare formulations, helping to inhibit the growth of certain fungi and bacteria on the skin.The ingredient is commonly found in products designed to address fungal skin conditions. It also serves secondary functions in formulations, including helping to reduce shine and maintain product texture.

Zinc undecylenate works through its antimicrobial properties, which stem from both the zinc ion and the undecylenic acid component. The zinc ion interacts with microorganisms to inhibit their growth, while undecylenic acid has been used traditionally as an antifungal agent.When applied topically, the ingredient remains on the skin surface where it can help suppress fungal and bacterial activity in affected areas.

Zinc undecylenate is typically found in specialised products designed for fungal skin concerns rather than general skincare. Follow the specific application instructions provided with your product. For fungal conditions, consistent twice-daily application tends to be recommended, though this should align with the product guidance and any advice from a dermatologist if the concern persists.

Zinc undecylenate has been assessed as safe in cosmetic formulations at typical use concentrations and shows minimal irritancy in testing. It is well-tolerated by most skin types when formulated appropriately.
