What Undecylenic Acid is, and why Nail Defender uses it
Undecylenic Acid is an 11-carbon fatty acid produced from castor oil, the oil pressed from castor beans. It has a long history in skin and foot-care products and is valued for its purifying qualities.
Nail Defender lists Undecylenic Acid first, making it the lead ingredient of the formula. It is there to care for the nail surface environment and help keep the area clean and balanced.
Clove Oil works alongside it in the same part of the formula.

Undecylenic Acid and Nail Defender: good to know
Nail Defender is a cosmetic nail-care spray, not a medicine. If a nail is painful, swollen, thick, or spreading to other nails, see a doctor or podiatrist.
