- Test substance stable to sunlight:
- not determined
- Test substance stable to metals / metal ions:
- not determined
- Conclusions:
- In the observed temperature range 0-520 °C the test item showed no thermal instability, only an endotherm transition occured attributed to the loss of water beginning at 260°C. As no exothermic events occured, the test item is not self-reactive.
- Executive summary:
During the DSC run only an endothermic thermal transition was observed, which could be caused by loss of water beginning at approx. 260 °C. After the test the test item remained visually unchanged.
As no exothermic events could be observed the test item is no subject to the classification procedures for self-reactive substances and the acceptance procedures for Class 1 explosives need not to be applied.

Description of key information
Silicic acid, aluminum sodium salt (CAS 1344-00-9, NAS) is an inert inorganic solid with a melting point greater than 300 °C.
Also, in the observed temperature range, 0-520 °C the read-across substance Silicic acid, aluminum magnesium sodium salt (CAS 12040-43-6, SMAS) showed no thermal instability, only an endotherm transition occurred attributed to the loss of water beginning at 260°C. As no exothermic events occurred, the read-across substance is not self-reactive.
Silicic acid, aluminum sodium salt (CAS 1344-00-9, NAS) does not contain any chromophore groups. Thus, no photochemical reactivity induced by sunlight is to be expected.
