The test substance was administered by oral gavage to two subsequent groups of three female Wistar rats at 2000 mg/kg body weight. Animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed after terminal sacrifice (Day 15).
No mortality occurred.
Hunched posture and/or piloerection were noted animals on Day 1.
Blue discolouration of the skin/fur, faeces and urine were noted for all animals on Day 1 and/or 2. This was considered to be due to the test substance.
The mean body weight gain shown by the animals over the study period was considered to be similar to that expected for normal untreated animals of the same age and strain.
No abnormalities were found at macroscopic post mortem examination of the animals. The oral LD50 value of K1600 black dye in Wistar rats was established to exceed 2000 mg/kg body weight.
According to the OECD 423 test guideline, the LD50 cut-off value was considered to exceed 5000 mg/kg body weight.
Based on these results, K1600 black dye does not have to be classified and has no obligatory labelling requirement for acute oral toxicity according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2011) (including all amendments) and Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (including all amendments).

and Labelling of Chemicals (GHS) of the United Nations (2011) (including all amendments) and
Regulation (EC) No 1272/2008 on classification, labelling and packaging of items and mixtures
(including all amendments). - Executive summary:
The study was carried out based on the guidelines described in: - OECD Guidelines, Section 4, Health Effects. No.403, "Acute Inhalation Toxicity", Sep 2009. - Commission Regulation (EC) No 440/2008, B.2. Acute Toxicity (inhalation), L142, May 2008. - EPA OPPTS 870.1300, Acute inhalation Toxicity. EPA 712-C-98-193, August 1998. - JMAFF Guidelines (2000), including the most recent revisions. K1600 black dye was administered as an aerosol by nose-only inhalation for 4 hours to one group of five male and five female Wistar rats. Generation as a dust was technically not possible and therefore the test item was mixed with water and generated as a liquid aerosol. Mortality and clinical signs were observed daily during the observation period and body weights were determined on Days 1, 2, 4, 8 and 15. Macroscopic examination was performed after terminal sacrifice (Day 15). The time-weighted mean actual concentration was 5.1 ± 0.15 mg/L. The nominal concentration (amount of test item used divided by the volume of pressurized air used) was 22 mg/L. The generation efficiency (ratio of actual and nominal concentration) was 23%. The concentration was measured at time points (n=18) that were equally distributed over the exposure period, the results of which demonstrated that the item was sufficiently stable. The generation was interrupted on three occasions in order to remove test item deposits from the system. To compensate for these interruptions, the generation time was elongated by 4 minutes in order to achieve an actual exposure time of 240 minutes. The Mass Median Aerodynamic Diameter (MMAD) and geometric standard deviation (gsd) were determined twice during the exposure period. The MMAD was 1.8 µm (gsd 2.1) and 1.4 µm (gsd 1.9). No mortality occurred. No clinical signs indicating test item related toxicity were seen during and after exposure. Black and blue staining by the test item of several body parts was seen throughout the observation period. Overall body weight gain in males and females was within the range as expected for rats of this strain and age used in this type of study. No abnormalities were found at macroscopic post mortem examination of the animals. The inhalatory LC 50, 4h value of K1600 black dye in Wistar rats was established to exceed 5 mg/L. Based on these results K1600 black dye does not have to be classified and has no obligatory labelling requirement for acute inhalation toxicity according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2011) (including all amendments) and Regulation (EC) No 1272/2008 on classification, labelling and packaging of items and mixtures (including all amendments).
