TS No. 154: Measurement on Biodegradation of Poorly Water-soluble Materials

Biodegradability is one of the most important parameters for the environmental fate of a substance. There are three types of biodegradation process: Primary biodegradation is the measurement of conversion of an organic substance into different products by biological system. This is the first step in biodegradation. Readily biodegradation occurs when biodegradation performance is greater than … Read more

TS No. 153: Determination of Isopropyl P-Toluenesulphonic Acid Ester in Cosmetic Products

Isopropyl p-toluenesulphonic acid esters (IPTS) is a by-product that may be formed during synthesis of isopropyl palmitate (IPP) and isopropyl myristate (IPM). The synthesis route is via esterification of palmbased palmitic and palm kernel-based myristic acids, by reaction with isopropanol. Under certain reaction conditions (anhydrous, no base and high temperature) isopropyl alcohol may react with … Read more
