Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of the study, treatment did not achieve a stimulation index of =3; therefore, it was considered that the test item does not have the potential to cause skin sensitisation. This study is considered to be relevant, reliable and adequate for risk assessment and for classification purposes.
- Executive summary:
The objective of this OECD 429 study was to determine the delayed contact hypersensitivity potential of EC-903-162-9.
The study was performed using female CBA/Ca mice. A preliminary test was conducted by administering a 50% concentration of test item to two mice. Each mouse received an open application of 25 µL of test formulation onto the dorsum of each ear.
As a result of the findings from the preliminary test, formulation concentrations were selected for the main study. Control animals from a concurrent study, Charles River Study, No. 521627, also acted as controls for this study. In addition, a group from the concurrent study was treated with hexylcinnamicaldehyde (HCA), a chemical known to induce skin sensitisation, in order to demonstrate that the selected vehicle, corn oil, was suitable for this test method. The study design for the main study was as follows:

The vehicle control group received only corn oil. Each mouse received an open application of 25 µL of the appropriate formulation onto the dorsum of each ear for 3 consecutive days. Three days after the final application each animal received an intravenous injection of [methyl-3H] thymidine into the lateral tail vein. Approximately 5 h later the draining auricular lymph nodes were collected in order that incorporation of tritiated thymidine could be assessed by scintillation counting.
The stimulation indices (SI) for groups of mice that received the test aricle at concentrations of 2.5%, 10% or 50% were 1.76, 1.92 and 2.98, respectively. The group treated with HCA recorded a stimulation index of 8.09. This was considered to demonstrate competent performance of the test procedures.
Under the conditions of the study, since treatment did not achieve a stimulation index of =3, it was considered that the test item does not have the potential to cause skin sensitisation.
