Hypoallergenic stabilized aloe vera gel

Abstract

The clear gel of aloe vera leaves is processed to provide a durable preparation preserving the therapeutic qualities of the fresh gel while essentially eliminating the rare but important idiosyncratic sensitivities encountered from stabilized aloe vera gel of the prior art. The process includes mechanically separating the aloe vera gel matrix from the leaf itself and thereafter adding a catalytic amount of a non-toxic oxidant to the fresh gel which is brought to a temperature of from about 35 degrees C. to about 80 degrees C. Ascorbic acid is then employed as a non-toxic antioxidant to arrest catalytic oxidation and a non-toxic buffer is then added in order to maintain the pH of the stabilized gel composition in a range of from about 4 to about 6. The resulting stabilized aloe vera gel composition closely approaches a nonallergenic status which is a substantial improvement over established aloe vera gels available heretofore, making it especially useful for application to facial areas where such sensitivities are more likely to appear in those few patients who are susceptible. Since treatment of such patients with any effective medication is often problematical, avoidance of interfering sensitivities is of special significance and highly desirable.
