- Test Substance Preparation and Administration
Healthy albino rats were released from quarantine. Each animal was prepared on the day prior to treatment by clipping the dorsal surface of the trunk free of hair to expose not less than 10% of the total body surface area. Care was taken to avoid abrading the skin. Only those animals with exposure areas free of pre-existing skin irritation or defects were used for this study. All animals were treated with 5050 mg/kg (5.07 mL/kg) of undiluted test substance. An individual dose was calculated for each animal based on its Day 0 body weight just before exposure. The test substance was applied evenly to each exposure area in a thin, uniform layer. The area of application was covered with a 2 x 4 inch surgical gauze patch and secured with a non-irritating adhesive tape. The trunk of each animal was then wrapped with vet wrap that was secured in place with non-irritating adhesive tape to prevent possible ingestion of the test substance. - Duration of exposure:
- Removal of the Test Substance
After 24 hours, the wrappings were removed. The test sites were gently washed with room temperature tap water and a clean cloth to remove as much residual test substance as possible. - Doses:

- 5 males per dose. 5 females per dose.
- Control animals:
- no
- Details on study design:
- In-Life Observations
Observations for mortality and clinical/behavioral signs of toxicity were made at least three times on the day of dosing (Day 0) and at least once daily thereafter for 14 days. Individual body weights were recorded just prior to dosing and on days 7 and 14.
Dermal Irritation Observations
Observations for evidence of dermal irritation were made at approximately 60 minutes after removal of wrappings and on days 7 and 14.
Postmortem Observations
On Day 14 after dosing, each animal was euthanized by CO2. All study animals were subjected to gross necropsy and all abnormalities were recorded.
Results and discussion
- Preliminary study:
- All (male and female) were normal at each observation.
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 5 050 mg/kg bw
- Based on:
- test mat.
- Mortality:
- There was no mortality during the study.
- Clinical signs:
- other: Clinical signs of toxicity are presented in Table 2. All animals appeared normal for the duration of the study. There were no signs of dermal irritation at any observation during the study.

Applicant's summary and conclusion
- Interpretation of results:
- Category 5 based on GHS criteria
- Conclusions:
- The test substance, Carbon Power (i.e., FBS Defense), was evaluated for its acute dermal toxicity potential and relative skin irritancy when administered to albino rats. The acute dermal LD50, as indicated by the data, is greater than 5050 mg/kg in males and females. FBS Defense does not cause dermal toxicity, and these results are transferable to FBS Gold.
