Link to relevant study records

Reference

Endpoint:

acute toxicity: oral

Type of information:

experimental study

Adequacy of study:

key study

Study period:

1974

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: Basic data given, but considered sufficiently reliable for the purpose of hazard assessment.

Qualifier:

equivalent or similar to guideline

Guideline:

OECD Guideline 401 (Acute Oral Toxicity)

Deviations:

no

Principles of method if other than guideline:

Mice were given a single oral dose of test substance at 5000 mg/kg bw and then observed for 14 days.

GLP compliance:

no

Remarks:

pre-GLP

Test type:

standard acute method

Limit test:

yes

Specific details on test material used for the study:

Vehicle:

not specified

Doses:

5 g/kg bw

No. of animals per sex per dose:

No data

Control animals:

Preliminary study:

Not applicable

Key result

Sex:

not specified

Dose descriptor:

LD50

Effect level:

> 5 000 mg/kg bw

Based on:

test mat.

Mortality:

2/10 animals on Day 1

Clinical signs:

other: Lethargy

Gross pathology:

No data

Other findings:

None

None

Interpretation of results:

GHS criteria not met

Conclusions:

Under the test conditions, oral LD50 of test substance is higher than 5000 mg/kg bw in mice therefore it is not classified according to the Regulation (EC) N° 1272-2008 and GHS.

Executive summary:

In an acute oral toxicity study (limit test), 10 mice were given a single oral dose of carrot seed oil at 5000 mg/kg bw. Animals were then observed for mortality and clinical signs at least daily for 14 days.

Two out of 10 animals died on Day 1. Lethargy was observed. In this study, the oral LD50 of test substance was higher than 5000 mg/kg bw in rats.

 

Under the test conditions, oral LD50 of test substance is higher than 5000 mg/kg bw in mice therefore it is not classified according the Regulation (EC) N° 1272-2008 and GHS.

Endpoint conclusion

Endpoint conclusion:

no study available

Additional information

Acute toxicity: via oral route

In an acute oral toxicity study (limit test), 10 mice were given a single oral dose of carrot seed oil at 5000 mg/kg bw. Animals were then observed for mortality and clinical signs at least daily for 14 days.

Two out of 10 animals died on Day 1. Lethargy was observed. In this study, the oral LD50 of test substance was higher than 5000 mg/kg bw in rats.

 

Under the test conditions, oral LD50 of test substance is higher than 5000 mg/kg bw in mice therefore it is not classified according the Regulation (EC) N° 1272-2008 and GHS.

Justification for classification or non-classification

Harmonized classification:

The registered substance has no harmonized classification according to the Regulation (EC) No. 1272/2008.

Self-classification:

Acute toxicity via Oral route:

Based on the available information, the registered substance is:

- not classified according to the Regulation (EC) No. 1272/2008 and GHS.

Acute toxicity via Dermal route:This information is not available

Acute toxicity via Inhalation:This information is not available.

Specific target organ toxicity: single exposure (Oral):

The classification criteria according to the Annex VI 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.

Specific target organ toxicity: single exposure (Dermal): This information is not available

Specific target organ toxicity: single exposure (Inhalation): This information is not available.

Based on its composition (> 10% of aspiration toxicants or hydrocarbons), the registered substance is classified for aspiration hazard category 1, H304 according to CLP Regulation and GHS.
