Description of key information

3.4 mg/L at 20°C (ASTM E 1148, turbidity measurement; mean of 3 measurements; RL1; GLP)

Key value for chemical safety assessment

Water solubility:
3.4 mg/L
at the temperature of:
20 °C

Additional information

The water solubility of MDIPA-Esterquat C16-18 and C18 unsatd. was determined according to ASTM International E 1148 – 02, using turbidity measurement.

Three samples were measured resulting in 1.01 mg/L at 20°C, 1.9 mg/L at 20±0.3°C and 7.4 mg/L at 20±0.3°C. The arithmetic mean of 3.4 mg/L will be used for chemical safety assessment.

Remark of registrant to summary:

The main study for the determination of the water solubility was performed using turbidity measurements, instead of analytical determination of concentration, since no suitable method was available to remove undissolved test substance during the preliminary test.
