Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Remarks

When samples were setting on the filter paper, samples gave white smoke and caused char on the part of filter paper with all three testing.

With Dropping testing, samples gave off white smokes in all case and at the first and third testing, sparks were observed during dropping.

 

Interpretation of results:
GHS criteria not met
Conclusions:
On exposure this substance to air, this substance decomposes to liberate hydrogen chloride.
When this substance was poured from circa 1 m height onto a non-conbustible surface, spark was observed only during dropping, but on the non-combustible surface only white smoke (hydrogen chloride) was observed. Burning on the surface was not observed within 5 miniutes.
Executive summary:

This substance gave spark only during dropping from 1 m height onto a non-combustible surface. On the surface, only liberation of white gas (hydrogen chloride) was observed. No burning was observed anymore.

We come to conclusion that this substance is not classified as pyrophoric substance.

Description of key information

This substance gave spark only during dropping from 1 m height onto a non-combustible surface. On the surface, only liberation of white gas (hydrogen chloride) was observed. No burning was observed anymore.

We come to conclusion that this substance is not classified as pyrophoric substance.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

This substance reacts with oxygen and water/moisture in the air to decompose to hydrogen chloride, titanium oxide and aluminum oxide.

The liberated hydrogen chloride immediately extinguishes fire evenif this substance ignites spontaneously.

Justification for classification or non-classification

This substance inites only during dropping from 1 m height onto a non-combustible board.

But settling on the board, because of hydrogen chloride generation by decomposition, burning didn't last anymore.
