Additional information

The pigment cobalt magnesium tin spinel is environmentally and biologically inert due to the characteristics of the synthetic process (calcination at high temperatures, approximately 1000°C), rendering the substance to be of a unique, stable crystalline structure in which all atoms are tightly bound and not prone to dissolution in environmental and physiological media. Based on the resulting physico-chemical properties, especially the high insolubility of the pigment under environmental conditions, demonstrated by (Klawonn, 2017) via transformation/dissolution testing (7 and 28 days), the substance can be expected to not have a potential to cross or adsorb to biological membranes. Therefore, no reversible or irreversible adverse toxicological effects on aquatic or terrestrial life-forms are expected, and a PNEC derivation is scientifically not justifiable.

Conclusion on classification

Based on the high insolubility of the pigment under environmental conditions, demonstrated by (Klawonn, 2017) via transformation/dissolution testing (7 and 28 days), no reversible or irreversible adverse toxicological effects on aquatic or terrestrial organisms are expected.

Cobalt and tin concentrations at 1 mg/l loading rate in a 7-days full T/D test are below acute ecotoxicity reference values of the dissolved form of the contained metals, and classification criteria of Acute (Short-term) Aquatic Hazard are not met.

Further, Cobalt and tin concentrations at 1 mg/l loading rate in a 28-days full T/D test are below chronic ecotoxicity reference values of the dissolved form of the contained metals, and classification criteria of Chronic (Long-term) Aquatic Hazard are not met. Based on the high insolubility of the pigment under environmental conditions, reversible or irreversible adverse toxicological effects on aquatic or terrestrial organisms are not expected. Hence, classification as Aquatic Hazard is not required.
