No corrosive effects were noted.The test material did not meet the criteria for classification as irritant or corrosive according to EU labelling regulations. No symbol and risk phrase are required.
- Executive summary:
A study was performed to assess the irritancy potential of the test material to the skin of the New Zealand White rabbit. The method used followed the recommendations of the OECD Guidelines for Testing of Chemicals No. 404 "Acute dermal irritation/corrosion" (adopted 17 July 1992) and Method B4 of Commission directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).
The test material did not meet the criteria for classification as irritant or corrosive according to EU labelling regulations. No symbol and risk phrase are required.
Reference
The individual score for erythema/eschar and oedema are given in Table 1. Mean values required for EU labelling regulations are given in Table 2. (Please see Attachment 1).
Very slight erythema was noted at 2 treated skin sites one hour after patch removal.
All treated skin sites appeared normal at the 24 hour observation period.

- Irritant / corrosive response data:
- A single application of the test material to the non-irrigated eye of three rabbits produced moderate conjunctival irritation. dulling of the normal lustre of the cornea was also noted in one treated eye. All treated eyes appeared normal at the 48-hour observation.
- Other effects:
- None noted.
- Interpretation of results:
- not irritating
- Remarks:
- Migrated informationCriteria used for interpretation of results: EU
- Conclusions:
- The test material did not meet the criteria for classification as irritant according to EU labelling regulations. No symbols and risk phrases are required.
- Executive summary:
The method used followed that described in the OECD Guidelines for Testing of Chemicals No. 405 and Method B5 of Commission Directive 92/69/EEC (which constitutes Annex V of Council directive 67/548/EEC).
The test material did not meet the criteria for classification as irritant according to EU labelling regulations. No symbols and risk phrases are required.

- no adverse effect observed (not irritating)
Respiratory irritation
Endpoint conclusion
- Endpoint conclusion:
- no study available
Additional information
A human patch volunteer study was conducted for the purposes of worker safety assessment under the supervison of a medical practitioner and according to a Japanese dermatological standard. In addition, a study was performed for the purposes of EU NONS notification to assess the irritancy potential of the test material to the skin of the New Zealand White rabbit. The method used was OECD Guideline No. 404. A single 4 -hour, semi-occluded application of the test material to the intact skin of three rabbits produced very slight erythema. All treated skin sites appeared normal at the 24 -hour observation.
A study was performed to assess the irritancy potential of the test material to the eye of the New Zealand White rabbit. following OECD Guideline No. 405. A single application of the test material to the non-irrigated eye of three rabbits produced moderate conjunctival irritation. Dulling of the normal lustre if the cornea was also noted in one treated eye. All treated eyes appeared normal at the 48 -hour observation.
Reliability.
The above studies have all been ranked reliability 1 according to the Klimish et al system. This ranking was deemed appropriate because the studies were conducted to GLP and in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not effect the quality of the relevant results.
Justification for classification or non-classification
The test material did not meet the criteria for classification as irritant or corrosive according the EU labelling regulations during the dermal irritation study.
The test material did not meet the criteria for classification as an irritant (to the eye) according to EU labelling regulations. No symbol and risk phrases are required.
