Key value for chemical safety assessment

Additional information

[3 -(triethoxysilyl)propyl]urea hydrolyses in contact with water to the corresponding [3-(trihydroxysilyl)propyl]urea and 3-Ureidopropylsilanetriol, which have low log Kow values (<3) and thus have low potential for sorption. Therefore, in accordance with Column 2 of REACH Annex IX, the adsorption/desorption screening test does not need to be conducted for the silanol hydrolysis products.
