Results of animal screening tests of emulsified cottonseed oils of the glanded and glandless varieties justify attributing some of the undesirable effects to pigments and minor polar component. A bleaching earth‐alumina fractionation method for removal of pigments and polar components of cottonseed oil was developed whereby the triglyceride portion was obtained as an essentially pure, water‐white fraction. Bleaching earth and chromatographic alumina when used in sequence were very satisfactory adsorbents, at concentrations of 20 wt % of earth and a 1‐to‐1 wt ratio of alumina‐to‐oil. Thin‐layer chromatography indicated the presence of sterol esters in the fractionated oil, but no polar components were detected.
