The American Indian population, made up of well over 300 tribes, now numbers more than 1.5 million or over 0.6 percent of the U.S. population.

Trichlorocarbanilide has widely been used in cosmetics and household products, but the extremely low solubility of trichlorocarbanilide in water constrains the development of water-based products. In order to enhance the bioavailability, trichlorocarbanilide were micronized using supercritical fluid. Supercritical carbon dioxide was selected due to relatively low critical temperature and the ra...
