摘要：An allergen absorbent and blocking gel for topical application to the skincomprises an organophilic clay of the smectite type and a quaternary ammoniumcompound, having aryl or alkyl groups in the range of from 10 to 22 carbon atoms and avehicle comprising long-chain hydrocarbon or volatile silicone. The material can be madein the form of a stick, a salve or an aerosol spray. It is essential that the organophilic claygel be highly activated. This is accomplished by high-shear mixing and/or by the use of alow molecular weight polar organic dispersant, such as propylene carbonate. This canalso be accomplished using self-activating and self-dispersing clays which do not requirehigh shear or polar activators. Application of the resulting highly-activated gel to the skinresults in a blocking effect by means of the clay platelets and an absorption andretention of the urushiol oil allergen in the active tallow tails of the alkyl groups of thequaternary ammonium compound which has been ion exchanged with the clay.
