Description of key information

According to REACH, Annex VII, column 2, the study needs only to be conducted if: — based on structure, surface activity is expected or can be predicted, or — surface activity is a desired property of the material. If the water solubility is below 1 mg/l at 20 °C the test does not need to be conducted. 
The test substance does not contain both polar (hydrophilic) and non-polar (lipophilic) moieties, indicating a possible surfactant property. Surface activity is not a desired property of the substance. The water solubility is below 1 mg/L at 20 °C. Therefore the study needs not to be conducted and a surface activity of lithium titanium oxide is unlikely.
