Undecylenic Acid, Explained

KlaroNail Editorial Team

Undecylenic Acid has a less familiar name than tea tree oil or aloe vera, but it's one of the specifically targeted ingredients in KlaroNail's formula. Here's what it actually is.

A fatty-acid derivative

Undecylenic Acid is derived from castor oil and has a long history of use in topical formulas aimed at supporting nail and skin cleanliness.

Derived from castor oil Used in topical formulas since the 1950s
Illustrative overview only — not a measurement of potency or effect.

Why it's included specifically

Unlike many of the botanical oils in a typical topical formula, Undecylenic Acid is included for a specific, targeted purpose — helping address buildup at the source rather than a general skin-conditioning role.

In KlaroNail

Undecylenic Acid is one of the hero ingredients in KlaroNail's formula, paired with Tea Tree Oil and Clove Bud Oil for targeted support.

Worth knowing

For external use only. If you have broken or irritated skin, consult a healthcare provider before applying any new topical product.
