acute toxicity: oral
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Justification for type of information:
β-Alanine, N-(2-carboxyethyl)-, N-coco alkyl derivs., disodium salts has been used in this end point as a read-across substance for Sodium N-(2-carboxyethyl)-N-dodecyl-β-alaninate . A comparison of the two substances and a read-across justification can be found in section 13 of this dataset

Executive summary:

Substance supplied by Rhodia as Miranol JC-HA acute oral toxicity study with no adverse effect at a dose of 2000 mg/kg in female rats (based on 83% purity in water). The data was derived by a good quality GLP limit test in 2004

 

The lower molecular weight would suggest that has the potential to be more biologically active than the coco-amine derivative and together with the weight of evidence from similar substances, is considered to be a valid substance for read-across for acute toxicity
