Butane-1,3-diol
EC Number:
203-529-7
EC Name:
Butane-1,3-diol
Cas Number:
107-88-0
Molecular formula:
C4H10O2
IUPAC Name:
butane-1,3-diol
Test material form:
liquid
Details on test material:
Name of test material (as cited in study report): butylene glycol,
purity not stated, but "specifications of test material ... corresponding to those regularly employed in industry"

Test animals / tissue source

Species:
rabbit
Strain:
not specified
Details on test animals or tissues and environmental conditions:
male albino rabbits with healthy eyes (without defects)
animal weight: 2 kg

Test system

Vehicle:
unchanged (no vehicle)
Controls:
not specified
Amount / concentration applied:
0.1 ml
Duration of treatment / exposure:
18 h
Observation period (in vivo):
Evaluation of effects was performed after 1 h, 24 h, 2, 4 and 7 days.
Number of animals or in vitro replicates:
6 males
Details on study design:
The test substance was instilled under the lower lid of one eye and the lids were held closed for several seconds to prevent loss of the test substance.
The animals were kept immobilised for 18 h, and then transferred to their cages.
For the improved detection of opacity, the eyes were stained with 2% aqueous fluorescein solution. Examination was performed by an opthalmoscope and a retinographe.
The untreated eye served as control.
