Description of key information
The dispersion stability of Pigment Orange 71 was strongly depended on water hardness. Dissolution was excluded as the main cause of the apparent stability. The stability in 0 mM Ca(NO3)2 was intermediate. The stability in 1 and 10 mM Ca(NO3)2 was low.

Key value for chemical safety assessment
Additional information
The OECD TG 318 on Dispersion Stability of Nanomaterials in Simulated Environmental Media is the first nano-specific test guideline, published 2017. Here we applied it to an organic pigment in order to map the ranges of stability in different media of surface water.
