The destruction of cyclopropene fatty acids of cottonseed oil on exposure to light from a 500 W tungsten bulb was studied under various conditions in the laboratory. The Halphen test was used to determine the destruction. Visible light exerted a strong catalytic effect and oxygen, at least in traces, was necessary. In 4–12 hr the Halphen response was negative for refined cottonseed oil (0.2–10 ml) sealed in a 50 ml flask at 1 mm Hg without apparent peroxide development. No significant difference was noticed in the peroxide development pattern of the exposed and unexposed samples in the airoven stability test.
