Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- February 20, 1989 to April 14, 1989
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Guideline study performed in compliance with GLP, available as unpublished report, no restrictions, fully adequate for assessment.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Version / remarks:
- Directive 84/449/EEC, Annex V, A.6
- GLP compliance:
- yes
- Type of method:
- column elution method
- Specific details on test material used for the study:
- - Name of test material (as cited in study report): Tetrabenzylthiuram disulfide
- Substance type: Monoconstituent substance
- Physical state: Solid
- Storage condition of test material: At room temperature in the dark
- Lot/batch No.: RB82 + RB87 + RB88 + RB92 + RB69 - Key result
- Water solubility:
- <= 0.01 mg/L
- Temp.:
- 21 °C
- pH:
- >= 6.7 - <= 6.8
- Remarks on result:
- other: Water solubility range: 1E-6 and 1E-5 g/l at 20.5 ± 0.50 °C
- Details on results:
- - Mean recovery of the substance: 86%.
- The test substance concentration after 5 times preconcentration is between 15*10-6 and 35*10 6 g/l, which is near the detection limit and leads to a relatively large variability in the results.
- because the peaks of the pretreatment and decomposition of the test substance in water are large, (relating to the test substance peak) further preconcentration is not advisable.
- the preconcentration procedure introduces an additional variability
- the test substance decomposes in water (data submitted by the sponsor). Additional peaks were interpreted as decomposition product of the substance.

- 21 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
