- Irritant / corrosive response data:
- Application of the test article to healthy intact rabbit skin resulted in a primary irritation score of 1.78. Very slight reddening and very slight swelling were noted in two animals after 24 hours and in all animals from 48 hours to 7 days after application. All findings were reversible after 14 days. Local signs (mean values from 24 to 72 hours) consisted of grade 0.89 erythmea and grade 0.89 edema. No irreversible alterations of the treated skin were observed nor were corrosive effects evident on the skin.
- Other effects:
- No clinical signs of systemic toxicity or mortality occurred.
No staining by the test article of the treated skin observed.
Body weights were within normal range of viability.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based upon the referred classification criteria, Javanol is considered to be 'not irritating' to rabbit skin.
- Executive summary:
A key dermal irritation study was performed according to OECD guideline 404 (adopted 1992), EEC Commission Directive 92/69/EEC (1992) and in compliance with GLP.
The primary skin irritation potential of the test article was investigated by a topical application of 0.5 ml to 6cm2 intact dorsal skin of each of three young adult New Zealand White rabbits. The duration of the treatment was 4 hours.The scoring of skin reactions was performed 1, 24, 48 and 72 hours as well as 7 and 14 days after removal of the dressing. The scores of each animal at the following reading times (24, 48 and 72 hours) were used in calculating the respective mean values for each type of lesion.
The primary irritation score was calculated by totalling the individual cumulative scores at 24, 48 and 72 hours and then dividing by the number of data points. The primary eye irritation score was 1.78 (max 8.0). Local signs (mean values from 24 to 72 hours) consisted of grade 0.89 erythema and grade 0.89 edema.
Very slight reddening and swelling were noted in two animals after 24 hours and in all animals from 48 hours to 7 days after application. All findings were reversible after 14 days.
The test article did not cause staining of the treated skin. No corrosive effects were noted on the treated skin of any animal at any measuring interval.
Under the conditions of the this test, Javanol is not considered to be a skin irritant.
Based upon the test results and in accordance to the Regulation (EC) No 1272/2008 (CLP) and Globally Harmonized System of Classification and Labeling of Chemicals (GHS), Javanol is not classified.
