Use of Tattoo Colorants as Food Colours - Heavy Metals

Several investigations of Tattoo- and Permanent Make-Up products for heavy metals by authorities are leading to a ban of these products. There is, however, a EU directive for the maximum contents of heavy metals in food colourants. The permitted values are much higher than for Tattoo Products. If, therefore, products are withdrawn for use as a tattoo colourant it seems to be an alternative to use the products in food.

Here are the values in comparison:

COMMISSION DIRECTIVE 2008/128/EC

of 22 December 2008

laying down specific purity criteria concerning colours for use in foodstuffs

 

Purity

Water soluble matter Not more than 1,0 %

By total dissolution

Arsenic - Not more than 5 mg/kg

Barium - Not more than 50 mg/kg

Cadmium - Not more than 5 mg/kg

Chromium - Not more than 100 mg/kg

Copper - Not more than 50 mg/kg

Lead - Not more than 20 mg/kg

Mercury - Not more than 1 mg/kg

Nickel - Not more than 200 mg/kg

Zinc - Not more than 100 mg/kg

 

 mg/kg approx ppm 

ResAP(2008)1

Table 3 Maximum allowed concentrations of impurities in products for tattoos and PMU

Element or compound in ppm

Arsenic (As) 2

Barium (Ba) 50

Cadmium (Cd) 0.2

Cobalt (Co) 25

Chromium (Cr) (VI) 0.2

Copper (Cu) soluble 25

Mercury (Hg) 0.2

Nickel (Ni) As low as technically achievable

Lead (Pb) 2

Selenium (Se) 2

Antimony (Sb) 2

Tin (Sn) 50

Zinc (Zn) 50

We leave it up to the suppliers to decide wether they would like to use their tattoo or permanent make-up products as food colourants if they are withdrawn for use in tattooing.
