Applicant's summary and conclusion
- Conclusions:
- The pH of the test item was 6.5.The pH of the 1% (w/v) aqueous mixtures was 4.7.
- Executive summary:
The purpose of the study was to determine the physico-chemical properties for MLA-3202.
The pH of the undiluted test item and of 1% (w/v) aqueous mixtures of the test item was measured using a 906 Titrando, in accordance with the following guidelines:
CIPAC, Analysis of Technical and Formulated Pesticides, MT 75.3: “Determination of pH values”, CIPAC Handbook Volume J, 2000.
Organization for Economic Co-operation and Development (OECD), OECD Guideline for the Testing of Chemicals no. 122: “Determination of pH, Acidity and Alkalinity”, 26 July 2013.
United States Environmental Protection Agency (EPA), Product Properties Test Guidelines no. OPPTS 830.7000: "pH", August 1996.
The pH of two 1% (w/v) mixtures of the test item in double distilled water was measured using a 906 Titrando (Metrohm, Herisau, Switzerland) and a combined glass electrode (glass glass electrode and reference electrode, Metrohm). Also the pH of the undiluted test item will be measured in duplicate.
The pH meter wa calibrated using a 0.05 M potassium hydrogen phthalate buffer solution (pH 4.00) and a 0.05 M di-sodium tetraborate buffer solution (pH 9.22 at 20°C).
At the start and at the end of the measurements, pH of these buffer solutions was measured to ensure proper performance of the pH meter.
For the preparation of the 1% (w/v) mixtures, accurately weighed amounts of 1.0006 g and 1.0009 g of the test item were transferred into a 100 mL measuring cylinder, containing about 50 mL water. The volume was made up to 100 mL with water, the cylinder was stoppered and the dispersion was shaken vigorously by hand until completely mixed or dispersed. After it was left to stand for 1 minute, the combined glass electrode was immersed into the liquid and the pH was measured without stirring. The pH value was recorded after 1 and 2 minutes.
Because the pH value changed more than 0.1 unit during this equilibration time, the pH was also recorded 10 minutes after immersion of the electrode.
The pH of the undiluted test item was determined directly. The electrode was immersed into the test item and the pH value was recorded after 1 and 2 minutes.
The 1% (w/v) mixtures of the test item in double distilled water were opaque white suspensions with approximately 5 mL white foam.
The pH of the undiluted test item and of 1% (w/v) aqueous mixtures of the test item was measured using a 906 Titrando (Metrohm, Herisau, Switzerland).
The pH of the test item was 6.5.
The pH of the 1% (w/v) aqueous mixtures was 4.7.
