- Gross pathology:
- The macroscopic examination of the animals at the end of the study did not reveal treatment related changes. Consequently, no microscopic examination of organs was performed.
- Other findings:
- None
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the test conditions, the oral LD50 for test substance is higher than 2000 mg/kg bw and the LD50 cut-off may be considered to be higher than 5000 mg/kg bw in female rats. Therefore, the substance is not classified according to the annex I of the Regulation EC No. 1272/2008 (CLP) and to the GHS.
- Executive summary:
In an acute oral toxicity study (limit test) performed according to OECD Guideline 423 and in compliance with GLP, 6 female Sprague Dawley rats were given a single oral (gavage) dose of test item at 2000 mg/kg bw. Animals were then observed for mortality, clinical signs and bodyweights for 14 days and were all sacrificed for macroscopic examination.
No mortality occurred during the study. No clinical signs related to the administration of the test item were observed during the study. The body weight evolution of the animals remained normal throughout the study, similar between treated and control animals. The macroscopical examination of the animals at the end of the study did not reveal treatment-related changes.
Under the test conditions, the oral LD50 for test substance is higher than 2000 mg/kg bw and the LD50 cut-off may be considered to be higher than 5000 mg/kg bw in female rats. Therefore, the substance is not classified according to the annex I of the Regulation EC No. 1272/2008 (CLP) and to the GHS.
This study is considered as acceptable and satisfies the requirement for acute oral toxicity endpoint.

Additional information
Acute toxicity: oral
A key study was identified (ICARE, 2020, rel.1). In this acute oral toxic class method study performed according to the OECD guideline No. 423 and in compliance with GLP, six female Sprague Dawley rats received a single oral (gavage) dose of the test substance at a dose level of 2000 mg/kg bw. Animals were then observed for mortality, clinical signs and bodyweights for 14 days and were all sacrificed for macroscopic examination.
No mortality occurred during the study. No clinical signs related to the administration of the test item were observed during the study.The body weight evolution of the animals remained normal throughout the study, similar between treated and control animals. The macroscopical examination of the animals at the end of the study did not reveal treatment-related changes.
Oral LD50 > 2000 mg/kg bw
Justification for classification or non-classification
Harmonized classification:
The substance has no harmonized classification according to the Regulation (EC) No. 1272/2008.
Self classification:
Acute toxicity (Oral):
Based on the available information, the substance is:
- not classified according to the CLP as the oral LD50 is higher than 2000 mg/kg bw.
- not classified according to the GHS since there is no reliable evidence that indicates the LD50 to be in the range of Category 5 values (GHS criteria not met).
Acute toxicity (Dermal):
No information was available. Not required for substances at the REACH Annex VII tonnage level.
Acute toxicity (Inhalation):
No information was available. Not required for substances at the REACH Annex VII tonnage level.
Specific target organ toxicity: single exposure (Oral):
The classification criteria according to the Annex I of the Regulation (EC) No. 1272/2008 as specific target organ toxicant (STOT) – single exposure, oral are not met since no reversible or irreversible adverse health effects were observed immediately or delayed after exposure and no effects were observed at the guidance value (oral) for a Category 1 classification (C≤ 300 mg/kg bw) and at the guidance value (oral) for a Category 2 classification (2000 mg/kg bw≥C > 300 mg/kg bw). No classification is required.
The criteria for Transient Organ effects (STOT-SE Category 3) according to Annex I of the Regulation (EC) No. 1272/2008 are not met since narcotic effects were not observed in the acute oral toxicity study.
Specific target organ toxicity: single exposure (Dermal):
No information was available. Not required for substances at the REACH Annex VII tonnage level.
Specific target organ toxicity: single exposure (Inhalation):
No information was available. Not required for substances at the REACH Annex VII tonnage level.
Aspiration hazard:
The registered substance has more than 10% of its constituents classified as Aspiration hazard cat.1 but no data on the kinematic viscosity was available. Therefore, in a worst-case approach, and based on the typical composition, the substance should be classified for aspiration hazard category 1, H304 (May be fatal if swallowed and enters airways according to the regulation (EC) No. 1272/2008) according to CLP Regulation and GHS.
