Endpoint summary
Administrative data
Description of key information
3-hydroxy-2-(3-hydroxy-2-quinolyl)-1H-inden-1-one is regarded as non-toxic after oral and dermal applications.
Key value for chemical safety assessment
Acute toxicity: via oral route
Link to relevant study records
- Endpoint:
- acute toxicity: oral
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: the study is performed in 1980 similar to the guideline of nowadays, GLP not menioned
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Single dose administered; observation period 14 days; 5 male and 5 female rats tested.
- GLP compliance:
- no
- Test type:
- standard acute method
- Limit test:
- yes
- Species:
- rat
- Strain:
- Wistar
- Sex:
- male/female
- Route of administration:
- oral: gavage
- Vehicle:
- water
- Doses:
- 5000 mg/kg
- No. of animals per sex per dose:
- 5 males and 5 females
- Control animals:
- no
- Sex:
- male/female
- Dose descriptor:
- discriminating dose
- Effect level:
- 5 000 mg/kg bw
- Based on:
- test mat.
- Executive summary:
After single dosing of 5 male and 5 female rats with 5000 mg/kg no deaths, no clinical signs and no gross pathological findings were reported.
Reference
No deaths, no clinical signs, no gross pathological findings at the end of the 14 days observation period.
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed
Acute toxicity: via inhalation route
Endpoint conclusion
- Endpoint conclusion:
- no study available
- Quality of whole database:
- An acute Inhalation Toxicity study was initiated. The study was aborded before any animal was exposed to the compound based on the low maximal technical producible concentration that could be achieved.
Acute toxicity: via dermal route
Link to relevant study records
- Endpoint:
- acute toxicity: dermal
- Type of information:

- yes (incl. QA statement)
- Test type:
- standard acute method
- Limit test:
- yes
- Species:
- rat
- Strain:
- Wistar
- Sex:
- male/female
- Type of coverage:
- semiocclusive
- Vehicle:
- unchanged (no vehicle)
- Duration of exposure:
- 24 h
- Doses:
- 2000 mg/kg
- No. of animals per sex per dose:
- 5 males and 5 females
- Control animals:
- not required
- Sex:
- male/female
- Dose descriptor:
- discriminating dose
- Effect level:
- 2 000 mg/kg bw
- Based on:
- test mat.
- Executive summary:
Groups of 5 male and 5 female Wistar rats received a single dermal dose of 2000 mg/kg body weight of the test item applied semiocclusively for 24 hours.
A dose of 2000 mg/kg body weight was tolerated by male and female rats without toxicologically relevant clinical signs, mortalities, toxicological effects on body weight development and gross pathological findings.

Additional information
In an acute oral toxicity study conducted in 1990 no deaths, no clinical signs and no gross pathological findings were reported after dosing of 5 male and 5 female rats with 5000 mg/kg.
In an acute dermal study 5 male and 5 female rats received a single dose of 2000 mg/kg of the test item applied semiocclusively for 24 hours. Rats tolerated the dose without toxicologically relevant clinical signs, mortalities, toxicological effects on body weight development and gross pathological findings.
An acute inhalation toxicity study was initiated in 2014. The study was aborded before any animal was exposed to the compound based on the low maximal technical producible concentration that could be achieved.
