Applicant's summary and conclusion
- Executive summary:
The water solubility and the pH of substance "reaction mass of calcium hydrogen phosphonate and dialuminium tricalcium hexaoxide" (a.i. 90 %) was measured in a study performed as flask method according to EU Method A.6 (Water Solubility), 1984 and OECD Guideline 105 (Water Solubility), 1981.
An amount of approximately 0.46-0-55 g of the test substance was weighed into each of three Erlenmeyer flasks. To each flask, 50 mL double distilled water was added. The flasks were securely closed and placed on a magnetic stirring device in a thermostatically controlled water bath at 30°C. The content of each flask was stirred for 24, 48 or 72 hours. After the stirring periods, the flasks were removed from the water bath and re-equilibrated for 24 hours at 20.5 +/- 0.4°C, with occasional agitation. After the re-equilibration period, the samples were analysed on aluminium and calcium using an atomic absorption spectrometric method.
The pH value of each clear water sample from the main study was determined.
The water solubility of substance " reaction mass of calcium hydrogen phosphonate and dialuminium tricalcium hexaoxide" at 20.5 +/- 0.4°C was determined to be 0.68 +/- 0.04 g/L.
The pH of the solution was 11.4.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
