Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
- Endpoint:
- short-term toxicity to aquatic invertebrates
- Type of information:
- other: Weight-of-evidence
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Justification for type of information:
- As no specific data on the acute toxicity for “Docosanoic acid, monoester with glycerol” (CAS 30233-64-8) is available, a weight of evidence analysis based on existing data on the group of mono-, di- and triglycerides, fatty acids, all components with similar properties has been performed. Several test data on acute toxicity was identified on the group of mono-, di- and triglycerides - all concluding no acute toxicity up to the water solubility. Detailed information is given in the attached report.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- No acute, invertebrate toxicity data is available for the substance. The substance is a mono-glyceride, and the acute toxicity to invertebrased in based on a WoE approach (see attached WoE document for details).
- Key result
- Duration:
- 48 h
- Dose descriptor:
- EC50
- Effect conc.:
- > 0.001 mg/L
- Validity criteria fulfilled:
- not specified
- Conclusions:
- The substance is a mono-glyceride, and based on a WoE approach, it is concluded that the substance is not acutely toxic to aquatic invertebrates in concentrations up the water water solubility limit of the substance
- Executive summary:
The substance is a mono-glyceride, and based on a WoE approach, it is concluded that the substance is not acutely toxic to aquatic invertebrates in concentrations up the water water solubility limit of the substance
Reference
Description of key information
Glycerol monobehenate is a mono constituent substance with a purity of 80-90%. Test data on short-term toxicity to aquatic invertebrate are not available for Glycerol monobehenate. The environmental toxicity of this substance was therefore assessed based on a weight of evidence analysis.
A large set of test data on environmental toxicity have been found for the group of mono-, di- and triglycerides and on the environmental toxicity of the hydrolysis products of the substance to constitute a basis for conclusion on short-term toxicity of the substance.
Several test data on the acute toxicity is found on the group of mono-, di- and triglycerides and fatty acids - all concluding that no acute toxicity is shown at concentrations up to the water solubility. Hereby, a huge data set is available for the deriving a conclusion on the acute toxicity of the substance.
Based on the studies available in the present analysis, it is concluded that the compound “Docosanoic acid, monoester with glycerol” is not acutely toxic at concentrations up the water solubility of the substance:EC50(Invertebrates, 48 hr): > water solubility
The available information comprises adequate, reliable studies from reference substances with similar structure and intrinsic properties. The weight-of-Evidence approach is justified based on common functional group and common precursors/breakdown products. The information from these independent sources is consistent and provides sufficient weight of evidence leading to an endpoint conclusion in accordance with Annex XI, 1.2, of Regulation (EC) No 1907/2006.
