Additional information

The biodegradability of 'zinc phthalocyanine sulfonate' was tested in a GLP guideline study conducted in compliance with OECD 301 B (Ready Biodgradability: CO2 Evolution Test). Based on the CO2 evolution < 10% biodegradation of the substance was observed after 28 days by domestic activated sludge from a municipal sewage treatment plant [BASF SE, 2012].
