My original question was that I wished to dissolve 100mg of caffeine powder in oil but could not do it as caffeine was not soluble in oil. The answer was to dissolve soap in the oil first, then the caffeine. I've done some research and I propose to dissolve sodium lauryl sulphate in the oil first, then the caffeine. I therefore need to know; 1. If this will work, and 2. How much sodium lauryl sulphate I need to dissolve in the oil so that precisely 100mg of caffeine can then be completely dissolved in the oil solution?
