Abstract: The present invention provides for optimal extraction conditions for extracting yellow mustard gum from yellow mustard bran to provide for high yield. The four variables examined were extraction temperature, pH, water:solid ratio and extraction time. Of these variables, temperature and pH had a much greater influence on the yield and rheological properties of the extracted gum compared to water/solid ratio and extraction time. Optimum extraction conditions were temperatures between 50-70° C., pH 7-10, water/solid ratio of 40:1-60:1 and extraction time of 2-2.5 hr. The yield of gum obtained under the optimum extraction conditions was 30% of bran weight. The extracted gum exhibited maximum shear thinning flow behaviours. It can be incorporated into cosmetic products and skin lotions.

Abstract: The present invention is a replacement for petroleum jelly as a base for products suitable for application to the skin. It is comprised of vegetable oil and silica. The vegetable oil is preferably a canola oil and more preferably a high oleic acid/low linolenic acid canola oil. The silica is preferably untreated fumed silica powder. The vegetable oil is preferably present in the range of 50-90% and most preferably 80%. The silica is present in the range of 5-15% and most preferably 10%. Other ingredients which may be added include vitamin E, margarine or butter, starch, and sunscreen. The base of the present invention has a significantly higher melting temperature than petroleum jelly.
