- Executive summary:
Tests with Ethanol, 2,2'-oxybis-, reaction products with 3-(triethoxysilyl)-1-propanamine in water with the intent to determine readily biodegradability can not be performed due to technical reasons based on the chemical properties of the substance. Stability tests in water with test item has shown that it immediately polymerises to amorphous silicic acid ("silica gel"), while releasing ethanol (cf. Report 11 -18360/1 -14 / 12 -00834/1 -14; 13 -04771).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
