Skin Cap (Cheminova Laboratories International SA, Madrid, Spain) was sold in the United States in the mid-1990s. Its active ingredients were reportedly pyrithione zinc and sodium lauryl sulfate. However, analysis of 2 lots of Skin Cap demonstrated adulteration with clobetasol propionate.1 In August 1997, the US Food and Drug Administration halted its importation.2
