- Justification for type of information:
- 1. HYPOTHESIS FOR THE ANALOGUE APPROACH
Due to sharing similar structural, physical and chemical properties to CMS, synthetic amorphous silica and calcium silicate are considered appropriate for read-across purposes. - Reason / purpose for cross-reference:

- Odour:
- odourless
- Substance type:
- inorganic
- Conclusions:
- Synthetic amorphous silicas including precipitated silicas are white, fluffy and/or powdery amorphous forms of silicon dioxide. Due to sharing similar structural, physical and chemical properties to CMS, synthetic amorphous silica and calcium silicate are considered appropriate for read-across purposes. As for synthetic amorphous silicas, CMS is an inorganic odourless white powder following the drying process. Before the drying step, synthetic amorphous silicas including CMS exist as a white odourless paste.
