6-16. UNDECYLENIC ACID
a. Undecylenic acid (Desenex) is a fungistat, which is used to treat athlete's foot
and ringworm of the body. Since it is only fungistatic and not fungicidal, attention must
be directed to other hygiene, especially where there are raw lesions. Fungicidal foot
powder and undecylenic acid ointment both contain, in addition, the astringent zinc
undecylate to help reduce rawness and irritation. Response of athlete's foot to the drug
is often dramatic, but the infection sometimes persists despite treatment.
