- Tissue preparations
Male Sprague Dawley rats (200-300 g) received a single intraperitoneal injection of Aroclor 1254 (500 mg/kg body weight; Aroclor was diluted with sun flower oil 1:5 v/v) 4-5 days before sacrifice. The liver was homogenized in three volumes of sterile, cold KCI (150 mM, buffered with Na phosphate at pH 7.4). The homogenate was centrifuged at 10,000 g for 10 minutes. One volume of the resulting supernatant was nixed with one volume 24 mM MgCl2-10 mM KCI and one volume 12 mM NADP-15 mM glucose-6-phosphate-150 mM Na phosphate pH 7.4.
This preparation is termed 5-9 Mix. For all experiments fresh tissue preparations were used from animals which were sacrificed on the day of the experiment.
Bacteria
Bacteria were grown over night in nutrient broth (8 g Bacto Nutrient Broth (DIFCO) + 5 g NaCl/liter). For inoculation stock cultures which were stored at -70°C were used.
Mutagenicity experiments
The test compound, 500 μl S-9 Mix (or 500 μ1 150 mM KCI), 100 μl of the bacterial culture, and 2000 μl top agar (0.55 % agar, 0.55 % NaCI, 50 μM histidine, 50 μM biotin, 25 mM Na phosphate pH 7.4 45°C) were mixed in a test tube and poured onto a petridish with minimal agar (1.5 % agar, Vogel-Bonner E medium with 2 % glucose). After incubation for 2-3 days in the dark, colonies (his revertants) were counted.
The person who performed the counting did not know the specifications of the plates.
Every single experiment contained several different positive controls for checking the activity of the metabolizing system and the mutability of the bacteria as well as negative controls in the form of sterility controls and solvent blanks. - Rationale for test conditions:
- The mutagenicity experiments were performed as described by Ames with minor modifications.

- Additional information on results:
- In a previous investigation mutagenicity for Levafixblau 30170 was observed. This mutagenicity was found only in the presence of S-9 Mix and only at very high doses which seemed to be above the metabolic capacity of the S-9 Mix. Therefore, it was suggested that an impurity rather than Levafixblau itself was responsible for the mutagenicity.
In this study a highly purified preparation from Levofixblau 30170, HRW 2538-57 was tested with Salmonella typhimurium TA 100, TA 1537 and TA 98 in the presence and in the absence of S-9 Mix. In contrast to the originally tested Levafixblau, which was included in this study as a positive control, HRW 2538-57 showed no mutagenic effects with TA 100 in the presence of S-9 Mix. No mutagenicity was observed under all other experimental conditions. - Conclusions:
- No mutagenicity was observed under all experimental conditions for HRW 2538-57 (purified Reactive Blue 181).
The substance is not classifiable according to CLP criteria. - Executive summary:

- Additional information on results:
- A weak dose dependent mutagenic effect was observed with TA 100 in the presence of S-9 Mix. The compound was not mutagenic in the absence of S-9 Mix. Since in the presence of S-9 Mix the mutagenic effect increased up to the highest dose used (2500 μg), and since this is probably much above the metabolic capacity of the S-9 Mix, it is suggested that an impurity rather than the test substance itself was responsible for the mutagenic effect.
The mutagenic effect was very weak compared to that of the positive controls. No mutagenicity was observed with TA 98, TA 1535 and TA 1537. - Remarks on result:
- other: mutagenic effect increased when 1000 μg instead of 315 μg was used. Since this is probably much above the metabolic capacity of the S-9 Mix, it is suggested that an impurity rather than the test substance itself was responsible for the mutagenic effect
Applicant's summary and conclusion
- Conclusions:
- Reative Blue 181 showed a weak mutagenic effect at high doses in the presence of S-9 Mix with TA 100. Since in the presence of S-9 Mix the mutagenic effect increased up to the highest dose used (2500 μg/plate), and since this is probably much above the metabolic capacity of the S-9 Mix, it is suggested that an impurity rather than he test substance itself was responsible for the mutagenic effect.
Under the other experimental conditions no mutagenic effect was observed with Reactive Blue 181. - Executive summary:
The mutagenicity experiments were performed as described by Ames.
eactive Blue 181 was tested for mutagenicity with Salmonella typhimurium TA 100, TA1535, TA 1537 and TA 98 in the presence and in the absence of an activating system (S-9 Mix from induced rat livers). A dose dependent mutagenic effect was observed with TA 100 in the presence of S-9 Mix. The compound was not mutagenic in the absence of S-9 Mix. Since in the presence of S-9 Mix the mutagenic effect increased up to the highest dose used (2500 μg), and since this is probably much above the metabolic capacity of the S-9 Mix, it is suggested that an impurity rather than the test substance itself was responsible for the mutagenic effect.
The mutagenic effect was very weak compared to that of the positive controls. No mutagenicity was observed with TA 98, TA 1535 and TA 1537.
