Introduction

Heavy metals such as arsenic (As) and lead (Pb) are naturally occurring elements in the environment, including raw materials used in the manufacturing of cosmetics. This has raised concerns among consumers as heavy metals are detrimental to human health. To address such issues, regulatory bodies from different countries have established guidelines to limit heavy metals impurities in cosmetics. According to the ASEAN Harmonized Cosmetic Regulatory Scheme (AHCRS), the maximum limit of As and Pb in cosmetics should be less than 5 ppm and 20 ppm respectively. To determine the amount of heavy metals in ASEAN Cosmetic Methods, graphite furnace atomic absorption spectrometer (GFAAS) is used. Here, we introduce the analysis of As and Pb in cosmetics using Shimadzu AA-7000 atomic absorption spectrophotometer (AAS) with GFA-7000 graphite furnace atomizer.
