Ecotoxicological information

Short-term toxicity to aquatic invertebrates

Currently viewing:

Administrative data

Endpoint:
short-term toxicity to aquatic invertebrates
Type of information:
read-across based on grouping of substances (category approach)
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Data are being assessed for the use in a category approach. Available information are being judged as reliable with restrictions since it was conducted by a modeled and measured data.
Remarks:
Data are being assessed for the use in a category approach. Available information are being judged as reliable with restrictions since it was conducted by a modeled and measured data.
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.

Details on results:
There were no acute effects on aquatic invertebrates or algae with LC50 values exceeding either the water solubility of the substance or were greater than 100 mg/L. Two exceptions included sponsored substance, Fatty acids, C12-18, sodium salts (CAS 91032-12-1) and supporting substance, Hexadecanoic acid (CAS No 124-04-9), with algae EC50 values between 1 and 100 mg/L. No acute aquatic toxicity data were located for magnesium and calcium or ammonium aliphatic acid substances.

Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
The Aliphatic Acids category members possess properties indicating a hazard for the environment (acute toxicity to aquatic organisms between 1-100 mg/L for C6, and C12-18 sodium salts). Aliphatic Acids category members are readily biodegradable and are not expected to bioaccumulate.

The substance deemed to be non-toxic.
Executive summary:

The substance deemed to be non-toxic.
