Executive summary:

Test Guidance

The acute toxicity of the test substance when administered by a single oral gavage to rats was investigated according to OECD test guideline No. 420 and Commission Regulation (EC) No. 440/2008, B.1.

Method

To determine the dose level for the main study, one sighting study was conducted with one female RccHan:WIST (SPF) rat. The animal was treated with the test item at a dose level of 2000 mg/kg body weight by single oral gavage administration. The test item was formulated in Polyethylene glycol 300 (PEG 300) at a concentration of 0.2 g/mLand administered at a dosing volume of 10 mL/kg body weight. Since no mortality occurred in the animal dosed at 2000 mg/kg, four additional females were treated at this dose level in the main study. The animals were examined daily during the acclimatization period and mortality, viability and clinical signs were recorded. All animals were examined for clinical signs before treatment, within the first 30 minutes and approximately 1, 2, 3 and 5 hours after treatment on test day 1 and once daily during test days 2 - 15. Mortality/viability was recorded before treatment, within the first 30 minutes and approximately 1, 2, 3 and 5 hours after administration on test day 1 (with the clinical signs) and twice daily during testdays 2 - 15. Body weights were recorded at acclimatization start, on test day 1 (prior to administration), on test days 8 and 15. All animals were necropsied and macroscopically examined.

Results

No intercurrent deaths occurred during the course of the study. After treatment on test day 1, 2 of 5 animals showed ruffled fur at all observation time points. From test day 2 onwards, no clinical signs were observed in any animal. The body weight of the animals was within the range commonly recorded for this strain and age. No abnormal macroscopic findings were recorded at necropsy.

Conclusion

The median lethal dose of the test substance after single oral administration to female rats, observed over a period of 14 days, is: LD50(female rat): greater than 2000 mg/kg body weight.

Rationale for reliability incl. deficiencies:

other: Study conducted to GLP in accordance with recognised guideline

Justification for type of information:

With regard to why some higher tier testing was conducted and included in this dossier without prior to submission of a testing proposal to EU:  global chemical companies who manufacture and/or place substances on the global market are obligated to meet the relevant chemical control laws in each jurisdiction that they do business. For this EC number 941-129-0, additional testing was required in order to meet global registration requirements outside of the EU.  The requirements of Article 22 of REACH place a responsibility on the registrant to update their registration with relevant new information.  These additional studies required for non-EU global registration purposes were deemed as relevant information and hence they were included in the EU REACH dossier.

Method and materials

Five male and five female RccHan:WIST (SPF) rats were treated with the test substance at the limit dose of 2000 mg/kg by dermal application. The test item was formulated in PEG 300 at a concentration of 0.5 g/mL and administered at a dose volume of 4 mL/kg. The application period was 24 hours. The animals were examined daily during the acclimatization period and mortality, viability, clinical signs and local dermal signs were recorded. All animals were examined for clinical signs before treatment, within the first 30 minutesand approximately 1, 2, 3 and 5 hours after treatment on test day 1 and once daily during test days 2 - 15. Local dermal signs were noted once daily from test day 2 to 15. Mortality/viability was recorded before treatment, within the first 30 minutes and approximately 1, 2, 3 and 5 hours after administration on test day 1 (with the clinical signs) and twice daily during test days 2 - 15. Body weights were recorded on test day 1 (prior to administration) and on test days 8 and 15. All animals were necropsied and macroscopically examined.

Results

No intercurrent deaths occurred during the course of the study. Scratching was observed on the back of one female during the first two days after removal of dressing. No local dermal signs were observed throughout the entire observation period. The body weight of the animals was within the range commonly recorded for this strain and age. No macroscopic findings were recorded at necropsy.

Additional information

Oral

The acute toxicity of the test item when administered by a single oral gavage to rats was investigated according to OECD test guideline No. 420 and Commission Regulation (EC) No. 440/2008, B.1.

The median lethal dose of the test item after single oral administration to female rats, observed over a period of 14 days, is: LD50(female rat): greater than 2000 mg/kg body weight.

Dermal

In accordance with OECD Guideline 404 and EC Method B3, five male and five female RccHan:WIST (SPF) rats were treated with test item at the limit dose of 2000 mg/kg by dermal application. The test item was formulated in PEG 300 at a concentration of 0.5 g/mL and administered at a dose volume of 4 mL/kg. The application period was 24 hours. The animals were examined daily during the acclimatization period and mortality, viability, clinical signs and local dermal signs were recorded. All animals were examined for clinical signs before treatment, within the first 30 minutesand approximately 1, 2, 3 and 5 hours after treatment on test day 1 and once daily during test days 2 - 15. Local dermal signs were noted once daily from test day 2 to 15. Mortality/viability was recorded before treatment, within the first 30 minutes and approximately 1, 2, 3 and 5 hours after administration on test day 1 (with the clinical signs) and twice daily during test days 2 - 15. Body weights were recorded on test day 1 (prior to administration) and on test days 8 and 15. All animals were necropsied and macroscopically examined.

No local dermal signs were observed throughout the entire observation period. The body weight of the animals was within the range commonly recorded for this strain and age. No macroscopic findings were recorded at necropsy.

The median lethal dose of the test item after single dermal application to rats of both sexes, observed over a period of 14 days, is: LD50 (rat): greater than 2000 mg/kg body weight.

Inhalation

The substance is a liquid with a vapour pressure of 0.000028 Pa at 25°C and is used primarily as a component of lubricants and greases by workers and consumers. It is expected that inhalation exposure from these uses will be low and that the most likely route of exposure for workers and consumers is the dermal route.
