- Flußmittel Degussa h-Paste
- Test material form:
- semi-solid (amorphous): gel
- Remarks:
- migrated information: paste

Constituent 1
- Specific details on test material used for the study:
- The substance was initially pre-registered as EC 286-925-2 and this was the information reported in the analytical reports. Only after REACH SID refinements, the substance was correctly identified as an UVCB and required a refined EC entry. For this reason, the existing EC 286-925-2&name identifiers are reported in the testing material & in the testing robust study summaries

- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 0.1 g of the test product was applied Into the conjunctival sac of one eye of the correspondingly fixed rabbit, after previously carefully pulling the lower lid away from the eyeball. Thereafter the lids were gently held together for about 1 second in order to prevent loss of Instilled test substance. The other eye of each animal remained untreated and acted as control. - Duration of treatment / exposure:
- not applicable
- Observation period (in vivo):
- 1, 24, 48, and 72 hours after the instillation of the test substance (maximum 21 days)
- Number of animals or in vitro replicates:
- 3 female rabbits
- Details on study design:
- Only test animals without any signs of eye diseases were used in the study.
REMOVAL OF TEST SUBSTANCE
- Washing: the treated eyes were not rinsed with aqua font, after application of the test substance.
SCORING SYSTEM: according to the Draize scale
Apart from the assessment of the primary irritation of the test product, additional findings, which did not affect the eye, were recorded (systemic toxic effects).
TOOL USED TO ASSESS SCORE: the eyes were examined with a hand-slit-lamp (model Ophthalmoskop, supplied by Heine, type med. 261).

- Irritant / corrosive response data:
- The single instillation of 0.1 g Flußmittel Degussa h-Paste into the conjunctival sac of the rabbit eye caused slight changes in cornea and conjunctiva.
In the cornea signs of irritation with the grading 1 (scattered or diffuse opacity) occurred in 1 of 3 test animals already 1 hour after exposure of the test product. Firstly less than half of the corneal area and subsequently approximately one quarter of the corneal area were involved. This finding persisted up to day 14 of the observation period.
In the Iris no changes occurred due to the contact with the test product.
The conjunctiva reacted with redness, swelling, and discharge. These findings occurred in all 3 animals already after 1 hour of exposure of the test product. Redness was diffuse with the grading 2. Obvious swelling with partial eversion of lids (grade 2) occurred. The observed discharge led to moistening of adjacent lids and hairs. The changes were detectable up to 48 hours at the longest after exposure of the test product into the conjunctival sac. - Other effects:
- Systemic toxic effects did not occur after conjunctival application of the test substance. The general condition of the test animals was undisturbed.
