Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- GLP compliance:
- no
- Type of method:
- flask method
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Name of test material (as cited in study report): 2,2',2''-nitrilotriethanol citrate
- Physical state: Liquid
- Batch nr: SEALS 2014-63-2-001
- Water content of the test item: 24.10% - Key result
- Water solubility:
- > 590.03 g/L
- Conc. based on:
- act. ingr.
- Temp.:
- 20 °C
- pH:
- 6.3
- Remarks on result:
- other: pH of a 10% solution
- Details on results:
- The following amounts of test item were added to 2 g of water
- 0.1 g: liquid, clear
- 1.0 g: liquid, cloudy, yellow
- 2.0 g: liquid, cloudy, yellow
- 3.0 g: liquid, cloudy, yellow
- 4.0 g: liquid, cloudy, yellow
- 5.0 g: liquid, cloudy, yellow
- 6.0 g: liquid, cloudy, yellow
- 7.0 g: liquid, cloudy, yellow
With 7 g of the test item being mixed into 2 g of water, a liquid with a total weight of 9 g has been formed. This is equivalent to 77.7% (w/w) of the test item in the liquid. Therefore, the water solubility of the test item was determined to be > 777 g/L.
Reference
DATA ADAPTATION
Because the test substance is sampled with an appreciable amount of water (24.10 %), a data correction based on the purity of the test item was applied to express the water solubility in g water-free matter/L.
The calculation for this is done as follows:
WS(dry matter) = WS(measured) * (1 - 0.241) = 777 g/L * 0.759 = > 590.03 g/L
WS = water solubility
Description of key information
In a water solubility test performed according to OECD guideline 105 the water solubility of the test item was determined to be >777g/L at 20 °C. The water solubility of the dry matter substance was calculated to be >590.03 g/L.
Key value for chemical safety assessment
- Water solubility:
- 590.03 g/L
- at the temperature of:
- 20 °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).
