Description of key information

The water solubility of THPS 100% dried form was determined according to standard guidelines under GLP.
A preliminary test was performed at the maximum amount of 37700 g/L equivalent solubility at 21°C. One phase only was visible in all samples after 24 hours and therefore the test substance was considered infinitely soluble and a definitive test was deemed unnecessary.

Key value for chemical safety assessment

Water solubility:
37 700 g/L
at the temperature of:
21 °C

Additional information

The water solubility of THPS dry active substance (100%) was determined under GLP, According to OECD 105 guideline, EEC method A6 and US EPA/FIFRA subdivision D § 63-8.

A preliminary test to measure the solubility of the dry active substance was performed by shaking 8 weighed amounts of test substance and distilled water at 21 °C until complete dissolution. Minimum / Maximum amount tested were 0.1019 / 4.998 g of dry substance and 4.9203 / 0.1323 g of distilled (equivalent solubility of 20.7 / 37700 g/L).

One phase only was visible in all samples after 24 hours. Thus, the test substance was found to be infinitely soluble in water and a definitive test was deemed unnecessary
