Based on the low molecular weight, potential surface activity, and irritancy potential, it is likely that [Caprylhydroxamic Acid] will be able to be absorbed into the skin. Hydroxamic acids are known to inhibit certain enzymes such as urease, and therefore have been shown to have protein reactivity-an important factor in skin sensitization potential. The skin sensitization potential of [Caprylhydroxamic Acid] cannot be ruled out.
