Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:
relative density
Type of information:
(Q)SAR
Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a (Q)SAR model, with limited documentation / justification, but validity of model and reliability of prediction considered adequate based on a generally acknowledged source
Justification for type of information:
QSAR prediction

Key result
Type:
relative density
Remarks:
QSAR prediction
Density:
ca. 1.06 g/cm³
Remarks on result:
other: QSAR prediction
Remarks:
QSAR prediction
Conclusions:
Predicted density is 1,06 g/cm³.
Executive summary:

Density is 1,06 g/cm³.

Endpoint:
relative density
Type of information:
read-across based on grouping of substances (category approach)
Adequacy of study:
weight of evidence
Justification for type of information:
Important considerations for the read-across were:

Sodium Olivoyl Glutamate (the target chemical) has similar physico-chemical properties as the others members:
- "Aliphatic acid category" (the source chemicals);
- "Amino acid alkyl amides category" (the source chemicals);
- Sodium oleoyl glutamate (the source chemicals);

Key points are that the members share:
- the same structural features
- similar metabolic pathways
- common levels and mode of human health related effects
- function.
Key result
Type:
relative density
Remarks on result:
not measured/tested
Conclusions:
Overall, considering available data on the category members, density is 1,06 g/cm³.
Executive summary:

Density is 1,06 g/cm³.
