No heavy metals (chromium, lead, mercury, arsenic, cobalt, nickel) have been included as an ingredient in MULAC products, in accordance with the provisions of Annex II of EC Regulation no. 1223/2009. The potential presence of technically unavoidable traces, as these substances are found everywhere, does not compromise the general safety of the product. All products are formulated to minimise their presence, which is regularly verified with specific tests. As for nickel, our checks have always showed impurity levels below 10 ppm (less than 0.001%)
