Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Additional information

The test item is a solid, amorphous, inorganic, transparent, translucent or opaque substance. The determined melting point of the test substance ranges between 308°C and 501 °C, depending on the individual starting material content. The density of the test item at 20 °C ranges from 3.46 to 6.65 g/cm3.

Transformation/dissolution:

Test material with a PbO content of 38.4%:

After 7 days, the dissolution of Pb ranged from 17.0 ± 1.99 µg/L (pH 8) to 18.7 ± 2.08 µg/L (pH 6).

After 28 days, the dissolution of Pb ranged from 37.8 ± 3.64 µg/L (pH 8) to 60.1 ± 17.2 µg/L (pH 6).

Based on the nominal test item amount, the maximum dissolution of Pb at pH 6 from the test item corresponded to 6.01% (w/w); based on contained lead 5.95% (w/w).

Test material with a PbO content of 78.0%:

After 7 days, the dissolution of Pb ranged from 53.8 ± 8.53 µg/L (pH 8) to 562 ± 86.1 µg/L (pH 6).

After 28 days, the dissolution of Pb ranged from 110 ± 8.28 µg/L (pH 8) to 684 ± 22.8 µg/L (pH 6).

At pH 6, the maximum dissolution of Pb from the test item was 68.4% (w/w) based on nominal test item loading. Based on contained Pb, the dissolution corresponded to 94.3 % (w/w).
