Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: Epiderm Skin Model, cytotoxicity, MTT method
- Version / remarks:
- The experimental design is based on the original validation study performed by ZEBET (2000).
- Principles of method if other than guideline:
- Alternative testing to avoid the use of animals.
The experimental design is based on the original validation study performed by ZEBET (2000). A number of doses of the test article will be determined and idluted in the appropriate vehicle. The appropriate number of EpiDerm tissues will be treated with the test article or control dilutions for approximately 24 hours to allow penetration into the living tissue. Then, half of the cultures in each tratment group will ne subjected to 6 J/cm² of UVA light. The remaining half of each treatment group will be held at roon temperature in the dark. All the tissues will be returned to the incubator for a post exposure period of 21 +/- hours. The phototoxicity and toxicity of each test article are evaluated on the basis of cytotoxicity (i.e., the relative conversion of MTT by the EpiDerm tissues). Cytotoxicity data are presented in the form of relative survival (relative MTT conversion). - GLP compliance:

Results and discussion
Effect levels
- Key result
- Remarks on result:
- no indication of skin irritation up to the relevant limit dose level
- Remarks:
- did not show phototoxic effects at any of the tested concentrations.
Applicant's summary and conclusion
- Conclusions:
- The test article, Jojoba Esters, did not show phototoxic effects at any of the tested concentrations. Since the positive control, 0.02% chlorpromazine in HBSS, induced at least a 30% decrease in tissue viability in the presence of UVA exposure, compared to the viability in the absence of UVA exposure, the assay was considered valid.
