- No. of animals per dose:
- 10 animals
- Details on study design:
- RANGE FINDING TESTS: A pilot study, using extra animals from a previous study, indicated the 100% solution to be nonirritating under the conditions of this test. Since no vehicle was needed to dilute the diethyleneglycol dinitrate.
MAIN STUDY
A. INDUCTION EXPOSURE
- No. of exposures: 3
- Exposure period: 6 hours
- Test groups: DEGDN
- Control group: Since no vehicle was needed to dilute the diethyleneglycol dinitrate a vehicle control group was not used.
- Site:L flank
- Frequency of applications: once a week for three weeks
- Duration: 3 weeks
- Concentrations: undiluted
B. CHALLENGE EXPOSURE
- No. of exposures: 1
- Day(s) of challenge: two weeks following the third induction dose
- Exposure period: 6 hour
- Test groups: DEGDN
- Control group: The negative control group received diethyleneglycol dinitrate only on the day of challenge dosing. To distinguish between reactions from primary irritation and sensitization a negative control group was added that received undiluted diethyleneglycol dinitrate only on the day of challenge dosing. Ten males was used.
- Site: both flanks
- Concentrations: undiluted
- Evaluation (hr after challenge): 24, 48 and 72 hours
OTHER: - Positive control substance(s):
- yes
- Remarks:
- 1-chloro-2,4-dinitrobenzene (DNCB)
Results and discussion
- Positive control results:
- Dinitrochlorobenzene (DNCB) produced a marked response at all time points after the second and third induction doses, as well as after the challenge dose. Between 90% and 100% of the DNCB-treated animals exhibited a response 24 h following these induction and challenge doses. These reactions persisted, yielding scorable effects in 50-70% of the animals at 72 h after dosing.
Beginning with the second induction, severity scores for these responses to DNCB ranged from 0.6 to 1.4 at the 24 h scoring period. The highest score, 1.4, was observed on the left (induction) flank in response to the challenge dose. By 48 h the reactions had subsided somewhat and the severity scores ranging from 0.6 to 1.1 reflected this decrease. A further reduction was evident by 72 h, with the severity index ranging between 0.5 and 0.8.

Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Diethyleneglycol dinitrate exhibited no potential for inducing dermal sensitization under conditions of this study.
- Executive summary:
Diethylerieglycol dinitrate (DEGDN) was tested for its potential to produce sensitization via contact with the skin. Testing was performed on male guinea pigs using the Buehler Dermal Sensitization method. No evidence of dermal sensitization to DEGDN was obtained in this study.
