This aim of this standard is to provide a process for the determination of mercury in cosmetics by means of cold vapour atomic adsorption (AAS) after pressure digestion. The procedure was validated in 2015 by means of a multi laboratory study in combination with cold vapour AAS determination process for mercury with eight laboratories participating. Overall, seven samples representing different matrices (lipstick, tattoo colourant, body lotion, toothpaste, eyeshadow and water make-up) with varying mercury contents between 0,110 mg/kg and 5,84 mg/kg were analysed.
