Specific details on test material used for the study:
- Name of test material (as cited in study report): Cidex activated dialdehyde solution & Sporicidin cold sterilizing solution.
- Composition of test material, percentage of components: unknown. active ingredient ca 2%


Type of population:
A panel of 12 subjects, 9 females and 3 males, started and completed the study
Ethical approval:
confirmed and informed consent free of coercion received
Route of exposure:
Reason of exposure:
Exposure assessment:
not specified
Details on exposure:
The test panel was placed in a closed room and were exposed to an individual test substance each day. A different test solution was used on each of the five exposure days. Containers with the test material were placed in the room at 2 or more locations and were agitated and in total 8 hours of exposure took place.
To asses if any effects occured in between test days (minimum of 48 hrs) a questionaire including eye and respiratory irritaion questions was executed prior to each test day. The questionaire was followed by an occular examination. When irritation developed during exposure the subject was removed and interviewed. All subjects were screened and examined prior and at the end of the 8 hour exposure period.

Results and discussion

Results of examinations:
Cidex: The panel was exposed to Cidex on the first two exposure days. On the first exposure day 1/12 reported dryness of nose, 1/12 dryness of throat, 2/12 burning of eyes, 2/12 itching of eyes, 1/12 watery eyes and 10/12 detected odor. On the second exposure day 1/12 reported irritation of the nose, 1/12 burning of eyes, 1/12 stinging of eyes, 1/12 itching of eyes, 1/12 watery eyes and 11/12 detected odor.

Sporicidin: The panel was exposed to Sporicidin on the last exposure day (fifth). 1/12 reported watery eyes and 11/12 detected odor. No other effects were reported.

For both test materials, lachrymation, palpebral conjuctiva redness, and bulbar conjunctiva redness were not observed.
