Undecylenic Acid

What is Undecylenic Acid?

Undecylenic Acid is a fatty acid derived from castor oil, commonly used in antifungal treatments and as a preservative in personal care products. It possesses antimicrobial properties, making it effective against various fungi and bacteria. Undecylenic Acid is often found in formulations aimed at treating conditions like athlete's foot and other fungal infections.

Why do I have an intolerance?

While generally safe, some individuals may experience irritation or allergic reactions to Undecylenic Acid, particularly those with sensitive skin. Reactions can manifest as redness, itching, or rashes, especially when used in high concentrations or combined with other irritants.

What can I do about it?

If you are intolerant to Undecylenic Acid, it is best to avoid products containing this ingredient. Instead, consider using alternative antifungal agents like tea tree oil or clotrimazole, which may be less irritating. Always choose formulations designed for sensitive skin that focus on soothing and hydrating ingredients to help maintain skin integrity.
