Salts of HEDP are involatile and
are demonstrated to have high melting temperature of >450°C. The
requirement to test the substance for pyrophoricity and flammability in
contact with water was waived in accordance with Section 1 of REACH
Annex IX, because there is no indication on the basis of structure and
experience in use and handling that the substance is pyrophoric
(flammable in contact with air) or flammable in contact with water.
screening studies were performed with HEDP acid and HEDP-4Na according
to test method A.10 flammability of solids. In both cases the test
material failed to ignite and no further testing was performed. These
results are read-across to potassium salts of HEDP as
the salts are not expected to exhibit higher flammable properties than
their corresponding acids.
salts of HEDP are not classified for flammability based on read-across
from HEDP-acid and HEDP-4Na. Both substances failed to ignite in
preliminary screening studies performed in accordance with EU test
