APN002564 Determination of zinc oxide in sunscreen Be the first to rate this application

Description

The United States Pharmacopeia (USP) has updated General Chapter <591> «Zinc Determination» to include ion chromatography (IC) as a method to quantitatively determine zinc, including zinc oxide, in drug substance and drug product monographs. Zinc oxide is one of the active ingredients approved by the U.S. FDA for sunscreens. Zinc oxide determinations in sunscreens were previously demonstrated in Thermo Scientific Application Note 72680. This method here demonstrates the application using a Thermo Scientific™ Dionex™ Inuvion™ Core IC system, a new integrated, single channel, compact IC.
