Applicant's summary and conclusion

- Remarks:
- Migrated information
- Conclusions:
- In conclusion, according to the Globally Harmonized Classification System, CD 6003 XX administered orally at a dose level of 2000 mg/kg body
weight in male and female rats under the conditions of this study is considered to be a Category 5 test article ( i.e., the oral LD50 of CD 6003 XX in
rats is greater than 2000 mg/kg). - Executive summary:
The toxicity of the test article, CD 6003 XX, was evaluated following a single dose to rats based on the OECD Guidelines No. 423.
A limit test was conducted using a step-wise procedure.Three female rats received the test article suspended in 1 % carboxymethylcellulose/0.2 % Tween 80 at 2000 mg/kg body weight. Doses were administered at a dose volume of 10 mL/kg based on the most recent body weight.
All rats survived to study termination ( Day 16 ).
Clinical observations noted on Day 1, during the 1-hour continuous observations, were limited to males and included : slight hypoactivity, hunched posture, squinted eyes and hypoactivity. In addition, one male had labored, audible respiration. In addition, one male had labored, audible respiration. At the 4-hour postdose observation, one male had slight hypoactivity. No clinical observations were noted at 6 hours postdose. On day 8, one female had red genital discharge. On day 15, two females had alopecia ( right inguinal or left marginal sacral areas ). All animals had normal weight gain from initiation of dosing to study termination. One female had distended intestines and purple spots on the mandibular lymph nodes, no other abnormal findings were noted in any animals at necropsy.
In conclusion, according to the Globally Harmonized Classification System, CD 6003 XX administered orally at a dose level of 2000 mg/kg body weight in male and female rats under the conditions of this study is considered to be a category 5 test article ( i.e., the oral LD50 of CD 6003 XX in rats is greater than 2000 mg/kg).
