Results and discussion
Any other information on results incl. tables
Skin mean thickness of the skin organ cultures : 1.847 +/- 0.23 mm
Percutaneous absorption: after 24 h of exposure the % of absorption remained lower than 0.1% of the applied dose when test item was applied in oil-in-water emulsion or in isopropyl myristate. Percutaneous absorption was influenced only marginally by the vehicle. RA3643 was absorped slightly better when applied in oil-in-water emulsion comparedor to isopropyl myristate. No consistent dose-dependency of the absorption were observed. When was applied as powder no skin absorption was observed.
Percutaneous absorption rate after 24 h: between 0.0 and 4.90 nmole/cm^2/h
Percutaneous absorption rate in the control group: 160.46 nmole/cm^2/h
Percentage of RA3643 in the skin tissue after 24 h: between 0.26 and 1.54 % of the applied dose
Cytotoxicity : no statistically significant differences in LDH leakage was observed between the test group 24 h after application.No damage in exposed skin cultures was noted.
Applicant's summary and conclusion
- Conclusions:
- RA3643 did not induce toxicity in human skin cultures.
RA3643 showed in vitro a very low percutaneous absorption (less than 0.1% of the applied dose) and was found not to be toxic to hyman skin cultures.
