 Partition coefficient

Log Pow = -1.59 (for Chlorendic acid)

 Water solubility

0.499 g/l for Chlorendic acid < 2.5 E-03 g/l for Chlorendic anhydride

 Surface tension

72.0 mN/m (90% saturated solution) Due to rapid hydrolysis result for chlorendic acid.

 Flash point

Flash point is a property relevant to liquids and low melting point solids and so is waived in accordance with Section 2 of annex XI of the REACH regulation

 Auto flammability

Explosivity study not undertaken as Chlorendic Anhydride is used as a flame retardant.

 Flammability

Explosivity study not undertaken as Chlorendic Anhydride is used as a flame retardant.

 Explosiveness

Explosivity study not undertaken as Chlorendic Anhydride is used as a flame retardant.

 Oxidising properties

In accordance with column 2 of REACH Annex VII, the study does not need to be conducted because on the basis of its chemical structure, the substance is incapable of reacting exothermically with combustible materials.

 Stability in organic solvents

In accordance with column 1 of REACH Annex IX, the study is only required if stability of the substance is considered to be critical.

 Dissociation constant

Study not undertaken as Chlorendic Anhydride readily hydrolyses.

 Viscosity

In accordance with section 2 of REACH Annex XI, the viscosity does not need to be performed as the substance is a solid.
