Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:
developmental toxicity
Type of information:
migrated information: read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Standard method, GLP-compliant, adequate experimental details for assessment

Qualifier:
equivalent or similar to guideline
Guideline:
EU Method B.31 (Prenatal Developmental Toxicity Study)
GLP compliance:
not specified

Test material

Reference
Name:
Unnamed
Type:
Constituent
Details on test material:
light brown liquid

Test animals

Species:
rat
Strain:
other: COBS CD (SD) BR

Administration / exposure

Route of administration:
inhalation: vapour
Type of inhalation exposure (if applicable):
whole body
Vehicle:
unchanged (no vehicle)
Analytical verification of doses or concentrations:
yes
Details on mating procedure:
Females were paired with male (sexually mature) of same strain after 13 days acclimation period. Females examined for copulatory plug daily. Presence of a plug indicated evidence of mating (gestation Day 0)
Duration of treatment / exposure:
Gestation Day 6 to 15
6 hours per day
Frequency of treatment:
once per day (6h)
Duration of test:
20 days (10days of exposure)
No. of animals per sex per dose:
20 female: 0 ppm
20 female: 100 ppm (nominal)
20 female: 400 ppm (nominal)
Control animals:
yes

Examinations

Maternal examinations:
Body weight, food consumption
general appearance, behaviour and condition
Pathology: thoraric and visceral organs were examined
Ovaries and uterine content:
Uteruses were removed from each rat and opened. The live and dead foetuses, implantation site and placement in the uterine horns and resorption sites were recorded
Fetal examinations:
Examined externally and weighed
Two-thirds of foetuses of each litter were examined for skeletal abnormalities
Remaining foetuses of each litter were prepared by fixing in Bouin's fuild for later examination looking for changes in the soft tissues of visceral and thoracic organs and the head
