- Study period:
- 2000.04.04-2000.09.21
- Reliability:
- 1 (reliable without restriction)

- Deviations:
- not specified
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Deviations:

- GLP compliance:
- yes
- Type of method:
- flask method
- Water solubility:
- > 4 000 g/L
- Temp.:
- 20 °C
- pH:
- 9.1
- Details on results:
- NA
- Conclusions:
- The solubility of L-TEE in water was determined in accordance to EC Method A6 and OECD Guideline 105.
The solubility of L-TEE in double-distilled water was determined to be greater than 4000 g/L with a nominal pH of 9.1. - Executive summary:
The solubility of L-TEE in water was determined in accordance to EC Method A6 and OECD Guideline 105.
To 5 mL double-distilled water, an amount of 10 g of L-TEE was added twice. As it fully dissolved the test was stopped. Cooling the solution to 20°, no deposit was observed.
The solubility in double-distilled water was determined by a simplified (non-analytical) shake flask procedure to be > 4000 g/L with a resultant pH of nominally 9.1.

Description of key information
The water solubility of L-TEE was determined to be >4000 g/L at 20°C.
Key value for chemical safety assessment
- Water solubility:
- 4 000 g/L
- at the temperature of:
- 20 °C
Additional information
The solubility of L-TEE in water was determined in accordance with EC Method A6 and OECD Guideline 105.
To 5 mL double-distilled water, an amount of 10 g of L-TEE was added twice. As it fully dissolved, the test was stopped. Cooling the solution to 20°, no deposit was observed. Therefore the solubility of the test substance at this latter temperature is considered to be in excess of 4000 g/L.
The solubility in double-distilled water was determined by a simplified (non-analytical) shake flask procedure to be > 4000 g/L with a resultant pH of nominally 9.1.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
