Transferable picture tattoo seals and face painting pens and crayons were analyzed by HPLC for the presence of formaldehyde. Incubated in artificial perspiration for 2 hours at 40 deg., all seals showed elution of formaldehyde. Meanwhile, incubated in water instead of artificial perspiration, some seals did not show elution of formaldehyde. Formaldehyde elution increased with time. For face painting tools, fluorescent crayons showed formaldehyde, but other crayons and pens did not show the substance.
