Abstract
Abstract DSC is a rapid and sensitive tool for the determination of the melting point, moisture content, purity, and heat of fusion of certifiable colors. The relative stability and the identification of the colorants may also be deduced from the thermograms. The procedures outlined require only a few milligrams of sample and provide a permanent record. Attempts to obtain similar information for natural color additives were unsuccessful due to the inability to obtain reproducible thermograms.
