Answer
Discussion:
Two products are at the root of the problems namely salicylic acid that is not fully soluble in this concentration and castor oil that is insoluble in the water-alcohol mixture. In order to make both soluble, the salicylic acid will have to be used with an increased alcohol level while the castor oil will be applied for solubilisation.
