Test animals
- Species:
- guinea pig
- Strain:
- not specified
Test system
- Type of coverage:
- occlusive
- Preparation of test site:
- shaved
- Vehicle:
- other: 10% w/v in Mineral Spirits
- Controls:
- no
- Amount / concentration applied:
- The test substance was in a suspension (10 % w/v) in Mineral Spirits.
- Duration of treatment / exposure:
- 24 hr application to skin, followed by 24 hr rest. Repeated for 10 applications.
- Observation period:
- 24 and 48 hrs after challenge, which followed 2 week rest period after cycle of 10 applications (20 days)

Applicant's summary and conclusion
- Interpretation of results:
- Category 3 (mild irritant) based on GHS criteria
- Conclusions:
- The results of this study show only slight irritation (mean PDII of 1 at 24 hrs and a mean PDII of 0.4 at 48 hrs) after 10 repeated 24 hr applications to the skin and a subsequent challenge after a 2 week rest period.
- Executive summary:
The results indicate that TPP is slightly irritating to the skin and not a skin sensitizer.
