Effects on fertility

Description of key information

In oral reproductive and developmental toxicity studies of cetyl betaine in rats, the LOAEL for the dams was 50 mg/kg due to decreased body weight gain and a maternal NOAEL could not be calculated. The developmental LOAEL was 250 mg/kg and the developmental NOAEL was 150 mg/kg.

Link to relevant study records
screening for reproductive / developmental toxicity
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because a pre-natal developmental toxicity study is available
Justification for type of information:
In view of the absence of effects to reproductive organs in a 90 day study on this substance and in view of the absence of effects in development studies, further animal work cannot be justifed.
Reason / purpose for cross-reference:
data waiving: supporting information
Effect on fertility: via oral route
Endpoint conclusion:
no adverse effect observed

Justification for classification or non-classification
