- Conclusions:
- The substance is not irritating to the skin based on an in vivo study (OECD 404).
According to Regulation (EC) No 1272/2008 and subsequent adaptations, the substance does not require classification as skin irritant. - Executive summary:
The skin irritation potential of the substance was investigated according to the OECD guideline 404. A single dose of 0.5 g of the substance moistened with the vehicle was applied to the skin of four female Mol: Russian rabbits and covered semi-occlusive for an exposure period of 4 hours. In addition the vehicle alone was also applied to the skin of the rabbits. The test sites were examined for skin reactions after test item treatment and scored according to the Draize scale after 30 minutes as well as 24, 48 and 72 hours after application.
The following results were recorded:
Animal #1
Erythema: 0
Oedema: 0
Animal #2
Erythema: 0.33
Oedema: 0
Animal #3
Erythema: 0
Oedema: 0
Animal #4
Erythema: 0.33
Oedema: 0.33
At the 24 hour observation very slight erythema (score 1) was observed at two test sites. No further skin reactions were observed.
According to Regulation (EC) No 1272/2008 and subsequent adaptations, the substance does not require classification as skin irritant.
Reference
TEST CONCENTRATION: 20 %
At the 24 hour observation very slight erythema (score 1) was observed at one test site treated with a 20% test concentration.
TEST CONCENTRATIONS: 10 %, 5 %, and 1 %
No skin reactions were observed after test item applications, except for very slight oedema (barely perceptible) (score 1) at one test site treated with the 1 % test concentration during the 30 minute observation.

- Irritant / corrosive response data:
- Residual test material was noted around the treated eye of all animals one hour after treatment.
A dulling of the normal lustre of the corneal surface was noted in all treated eyes one hour after treatment. Areas of diffuse corneal opacity were noted in all treated eyes at the 24 and 48-hour observations with areas of diffuse to translucent corneal opacity at the 72-hour observation. Areas of diffuse corneal opacity persisted in one treated eye at the 7-day observation. Vascularisation of the cornea was also noted in this treated eye at the 7 and 14-day observations. At the beginning of the observation period the area of opacity was greater than three quarter, up to whole area for all treated eye and than became less severe until the opacity disappeared.
Iridial inflammation was noted in all treated eyes at the one, 24 and 48-hour observations, in three treated eyes at the 72-hour observation and in one treated eye at the 7-day observation. No other adverse iridial effects were noted.
Moderate conjunctival irritation was noted in all treated eyes one and 24 hours after treatment with minimal to moderate conjunctival irritation at the 48 and 72-hour observations. Minimal conjunctival irritation was noted in one treated eye at the 7-day observation. Petechial haemorrhage of the nictitating membrane was noted in one treated eye one hour after treatment.
Furthermore, moderate to severe discharge was observed 1 hour after treatment. Slight to moderate discharge was observed 24 hours after treatment.In two treated eyes the discharge was not observed anymore on day 7. In one treated eye discharge was not observed anymore at 48 hours after treatment. Lastly, in one treated eye the discharge disappeared at the 48 hour observation, but reappeared on day 7 and cleared on day 14. - Interpretation of results:
- Category 2 (irritating to eyes) based on GHS criteria
- Conclusions:
- The substance is irritating to the eyes.
According to the EC Regulation No. 1272/2008 and subsequent adaptations, the substance is classified as an eye irritant (Category 2; H319). - Executive summary:
The eye irritation potential of substance was investigated according to the OECD guideline 405 (1987). A single dose (0.1 mL; approx. 62 mg) of the substance was placed into the conjunctival sac of one eye of four New Zealand White rabbits.The other eye remained untreated and served as control. Ocular damage and irritation were assessed according to the Draize scale approximately 1 hour and 24, 48, and 72 hours as well as 7 and 14 days following treatment with the substance. Any other adverse ocular effects were also noted.
The following results were recorded for the four rabbits:
Animal #1
Cornea score: 1.33
Iris score: 1
Conjunctivae score: 2
Chemosis score: 2
Animal #2
Cornea score: 1
Iris score: 0.67
Conjunctivae score: 1.67
Chemosis score: 1.33
Animal #3
Cornea score: 1
Iris score: 1
Conjunctivae score: 2
Chemosis score: 2
Animal #4
Cornea score: 1
Iris score: 1
Conjunctivae score: 1.67
Chemosis score: 1.33
Residual test material was noted around the treated eye of all animals one hour after treatment. Dulling of the normal lustre of the corneal surface was observed in all rabbits 1 hour after treatment as well as slight iridial effects. At the beginning of the observation period the area of opacity was greater than three quarter, up to whole area for all treated eye and than became less severe until the opacity disappeared. Moderate conjunctival redness and chemosis was observed in all animals 1 hour after treatment. Furthermore, moderate to severe discharge was observed 1 hour after treatment. Slight to moderate discharge was observed 24 hours after treatment.In two treated eyes the discharge was not observed anymore on day 7. In one treated eye discharge was not observed anymore at 48 hours after treatment. Lastly, in one treated eye the discharge disappeared at the 48 hour observation, but reappeared on day 7 and cleared on day 14. Petechial haemorrhage of the nictitating membrane was noted in one treated eye one hour after treatment.
Overall, all effects were fully reversible within 7 days, except for one rabbit. In this rabbit the effects were fully reversible within 14 days, except for vascularisation of the cornea which was still observed on day 14. The vascularisation of the cornea was already observed on day 7.
According to the EC Regulation No. 1272/2008 and subsequent regulations, the test substance is classified as an eye irritant (Category 2; H319).
