Endpoint:
acute toxicity: oral
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1980-07-31 to 1980-08-14
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Study result presented as summary but includes all relevant information. Study was performed prior to implementation of GLP but carried out according to the principles of GLP.
Cross-reference
Reason / purpose for cross-reference:
read-across source
Reference
Endpoint:
acute toxicity: oral
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
other information
Justification for type of information:
Justification for the read-across from the introduced read-across supporting substance (CAS 67938 -21 -0) to the registration substance:
The introduced read-across supporting substance (CAS 67938-21-0) is structurally related to the registration substance. Both substances are fatty acid esters of polyglycerols, the only diffence being that the introduced read-across source substance (CAS 67938-21-0) is synthesized by using isostearic acid as fatty acid while the registration substance by using stearic acid.
Both substances are expected to undergo enzymatic hydrolysis resulting into the release of polyglyerols and the corresponding fatty acids (isostearic acid for the read-across supporting substance and the stearic acid for the registration substance. Isostearic acid as well as the stearic acid are well-investigated substances and occurs also endogenously. No difference in the acute oral toxicity can be reliably derived.
Reason / purpose for cross-reference:
assessment report
Interpretation of results:
GHS criteria not met
Executive summary:

No classification is warranted for the registration substance based on the read-across data.

Applicant's summary and conclusion

Interpretation of results:
practically nontoxic
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Based on the study results, the acute oral toxicity (LD50) of the test substance registered is greater than 5000 mg/kg body weight.
Executive summary:

Based on the study results, the acute oral toxicity (LD50) of Hoe S 2721 in the rat is greater than 5000 mg/kg body weight. Accordingly Hoe S 2721 is not subject for labelling requirements with regard to acute oral toxicity.
