| Chemical nature |
The listed HELIOGEN?pigments are phthalocyanines with a central divalent copper atom. Copper phthalocyanine pigments occur in various crystal modifications, of which the alpha form (reddish blue) and beta form (greenish blue) are the most technically significant. The alpha form can be stabilized by partial chlorination (0.5 chlorine atom per molecule). |
| Toxicology |
In experiments on animals, HELIOGEN?pigments did not display acute toxicity. Feeding tests on rats to determine the chronic toxicity revealed no toxicological finding whatever. No acute irritant effect was shown in tests to determine the acute irritation of the skin and mucous membranes. |
| Ecology |
Because they are chemically inert and practically insoluble in water, HELIOGEN?pigments are not environmentally hazardous. They can be removed from waste water by mechanical means. The high stability of the copper complex means that the pigment does not decompose to release ionic copper by hydrolysis, photolysis, or aerobic or anaerobic decomposition. |
| Labelling |
The above listed products are not dangerous substances in the sense of the German Ordinance on Dangerous Substances or of corresponding EU regulations. |
| Classification as dangerous goods |
The products are not classified as hazardous under transport regulations. |
| Heavy metal content |
HELIOGEN?pigments do not contain any lead, cadmium, chromium(VI) and mercury compounds in their formulations. The sum of the total contents of these elements, according to tests on standard samples, is less than 100 mg/kg. It is thus below the limit in the EU packaging directives and the American CONEG model.
Antimony < 20 mg/kg Chromium < 50 mg/kg Arsenic < 20 mg/kg Selenium < 20 mg/kg Lead < 20 mg/kg Mercury < 20 mg/kg Cadmium < 30 mg/kg Zinc < 20 mg/kg
Prim. aromatic amines < 100 mg/kg
The metal levels quoted are based on the detection limit of the analytical determination method used (X-ray fluorescence spectroscopy). The actual levels may lie well below these values. |
| Copper content |
HELIOGEN Blue K 6840 and K 7090 contain appr. 11 % and K 6902 and K 6911 D contain appr. 10,5 % chemically combined copper. |
| Halogen content |
Only the stabilized alpha HELIOGEN?types K 6902 and K 6911 D contain organically combined chlorine (approx. 3 %). All the other types listed do not contain any chemically combined halogen. |
| Food legislation |
According to tests on standard samples (Type 8081) the listed HELIOGEN?pigments conform to the demands on purity in the following food legislation (see also "Heavy metal content"):
Europe: Resolution AP (89) Germany: BgVV Empfehlung IX., 190. Mitteilung vom 1.6.1994 France: Brochure No. 1227 Italy: Decreto Ministeriale dated 21.3.1973 Spain: Resoluci del 4.11.82 de la Subsecretar de Sanidad USA: Listed on the FDA List (21.CFR, ?178.3297). |
| Toys |
According to tests on standard samples (Type 8082), the listed HELIOGEN?pigments conform to the demands on purity in the European standard on toys, i.e. EN 71, Part 3. |
| Registration status |
The components of the products are listed in the chemical inventories of the following countries: EU (EINECS), USA (TSCA), Canada (DSL), Japan (MITI), Australia (AICS), Korea (ECL), Philippines (PICCS, Final Version 1995), and Switzerland (BAGT No. 612200, Class free). |
Other legislation on chemicals |
