There have been concerns regarding the presence of heavy metals such as mercury (Hg) in cosmetics. Hg could be absorbed through the skin or ingested and accumulate in the body over time, causing adverse long-term health consequences. Hence, it is important to regulate and screen for the presence of Hg in cosmetics. According to USFDA 21 CFR 700.13, Hg is not allowed in any cosmetics except in trace amount of less than 1 ppm. The ASEAN Harmonized Cosmetic Regulatory Scheme (AHCRS) has also set 1 ppm as the maximum limit for Hg and provides method for the determination of Hg in cosmetic using cold vapour atomic absorption spectrophotometer (CVAAS).
This application news demonstrates the analysis of Hg in cosmetics using Shimadzu AA-7000 atomic absorption spectrophotometer (AAS) with MVU-1A Hg Vaporizer Unit.
