- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- GLP guideline study reliable without restrictions
- Justification for type of information:
- Disodium titanate substance (EC 234-802-9) has the molecular formula Na2TiO3 and its composition is expressed as (Na2O)x(TiO2), where x is ranging from 0.1 to 6 according to the SIP. This substance, Reaction mass of Disodium Hexatitanate and Sodium Metatitanate, has a value of x = 0.21, calculated from XRF results, has been identified as a mixture of two specific types of disodium titanate and is therefore within the scope of the disodium titanate SIP. It is assessed therefore that disodium titanate is an acceptable read-across substance for Reaction mass of Disodium Hexatitanate and Sodium Metatitanate

Description of key information
The relative density of disodium titanate is 2.8. The ambient temperature was determined to be 22.4 °C to 23.4 °C. According to the European Commission Regulation (EC) No. 440/2008, A.3., solids can be measured at ambient temperature (20 – 25 °C).
Key value for chemical safety assessment
- Relative density at 20C:
- 2.8
