Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The result obtained, in these experimental conditions, enable to conclude that the test item must not be classified, according to the criteria for classification, packaging and labelling of dangerous substances and preparations in compliance with the E.E.C. Directives 67/548, 2001/59 and 99/45. No symbol or risk phrase is required.
In accordance with the regulation (EC) No. 1272/2008, the test item must not be classified. No signal word or hazard statment is required. - Executive summary:
The test item was applied, as supplied, at the dose of 0.5g, under semi-occlusive dressing during 4 hours on an undamaged skin area of three New Zealand rabbits. The experimental protocol was established from the OECD guideline No. 404 dated April 24th, 2002 and the test method B.4 of the council regulation No. 440/2008 of 30 May 2008;
A very slight erythema was noted on the treated area of on animal, 1 hour after the patch removal and was totally reversible on day 3.
A sight yellow to blue coloration (not preventing erythema assessment ) was registered from the reading time 1 hour and remained on day 3 in all animals.
The results obtained, in these experimental conditions, enable to conclude that the test item not be classified, according to the criteria for classification, packaging and labelling of dangerous substances and preparations in compliance with the E.E.C. Directives 67/548, 2001/59 and 99/45. No symbol or risk phrase is required.
In accordance with the regulation (EC) No. 1272/2008, the test item must not be classified. No signal word or hazard statement is required.
