Description of key information
Dodecylamine (CAS 124-22-1) is readily biodegradable according to OECD criteria.
Due to structure and low water solubility, biodegradation of Copper phthalocyanine monosulfonic acid (CAS 28901 -96 -4) is not expected.
Key value for chemical safety assessment
Additional information
The Pigment additive FNC (CAS 73455 -75 -1) is composed of Copper phthalocyanine monosulfonic acid (CAS 28901 -96 -4) and dodecylamine (CAS 124-22-1). The assessment of the biodegradation potential is based on a read-across to information on these components as experimental data for the target substance itself are not available.
The ready biodegradability of dodecylamine (CAS 124-22-1) was assessed in two closed bottle tests according to OECD 301D and in one test similar to OECD 301C (MITI-I). All studies used activated sludge from WWTPs treating municipal sewage. In the closed bottle test performed by Hoechst (1994) the degradation reached 63% after 7 d of exposure. Ginkel et al. (1995, cited in BUA, 1997) published a degradability of 65% after 10 d and 77% after 28 d. Due to microbial toxicity Yoshimura performed the ready biodegradability test at two concentrations. At 100 mg/L, no oxygen consumption was observed. Therefore, the test concentration was reduced to 30 mg/L, leading to a degradation of 70% after 12 d. In all three tests the 10-day window was kept. The study by Hoechst (1994) was selected as key study based on the documentation of the study, while the two other results were selected as supporting studies.
It can be concluded that dodecylamine is readily biodegradable according to OECD criteria.
Due to the chemical structure and the extremely low water solubility of Phthalocyanines, biodegradation of Copper phthalocyanine monosulfonic acid (CAS 28901 -96 -4) is not expected. However, there are data on the biodegradability of single Phthalocyanines available. The biodegradability of Copper phthalocyanine (CAS 147-14-8) was tested in a study following OECD guideline 301 F using domestic activated sludge as inoculum [BASF AG 1988]. After 28 days of inoculation a degradation rate of less than 1 % was determined. The test results support the assumption that Phthalocyanines are only poorly biodegradable.
