Undecylenic acid is unsaturated fatty acid, which naturally occurs in sweat, and is commercially produced by the vacuum distillation of castor bean oil. It is recognized as GRASE by FDA, and is marketed over the counter to treat skin infections and to relieve itching. Undecylenic acid acts by inhibition of morphogenesis from yeast to hyphae forms.

Route of Administration: Topical

In Vitro Use Guide

To investigate effect of undecylenic acid on Candida albicans morphogenesis, cells were grown overnight at 30°C on YPD agar and harvested by scraping the cells from the plate and suspending in YPD broth. Two milliliters of cells at 106 cells/ml was distributed into tubes containing liner, approximately 0.5 g of liner per tube. The cultures were incubated at 39°C with agitation for 2 h; planktonic cells were analyzed microscopically to determine the percentage of cells with germ tubes. The presence of Undecylenic acid inhibited the appearance of germ tubes, with 10 μM UDA causing a sevenfold reduction.
