Physicochemical Properties for HBPA (100-1000T phase-in)

IUCLID section	Study name	Test guideline	Endpoint	Result / Comments
4.1	Rikabinol HB Physicochemical Properties	n/a	Appearance	White powder
4.2	Rikabinol HB Physicochemical Properties	EC Method A.1 OECD Method 102	Melting point	Rikabinol HB was determined to melt over the range of approximately 50 to 160°C.
4.3	Rikabinol HB Physicochemical Properties	EC Method A.2 OECD Method 103	Boiling point	The boiling temperature of Rikabinol HB was not determinable, as the test substance decomposed at temperatures above approximately 280°C without boiling.
4.4	Rikabinol HB Physicochemical Properties	EC Method A.3 OECD Method 109	Relative density	The relative density of Rikabinol HB was found to be 1.04.
4.5	Certificate of granulometry	No guidelines, volumetric distribution undertaken by NJC.	Particle size	ca. 10 mm3  3%     ca. 30 mm3  11.8%  ca. 50 mm3  19%     ca. 70 mm3  11.4%   ca. 90 mm3   5.2%
4.6	Rikabinol HB Physicochemical Properties	EC Method A.4 OECD Method 104	Vapour pressure	Rikabinol HB was found to have a vapour pressure of 9 x 10-4 Pa at 25°C.
4.7	Rikabinol HB Physicochemical Properties	EC Method A.8 OECD Method 117	Partition coefficient	Log10 Pow = 2.3
4.8	Rikabinol HB Physicochemical Properties	EC Method A.6 OECD Method 105	Water solubility	Rikabinol HB was found to have a water solubility of 192 mg/l at 20°C.
4.10	Rikabinol HB Physicochemical Properties	EC Method A.5 OECD Method 115	Surface tension	The surface tension of a 90% saturated aqueous solution of Rikabinol HB was found to be 51.5 mN/m. As the result was less than 60 mN/m, the test substance was considered to be surface active.
4.11	n/a	n/a	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.
4.12	Rikabinol HB Physicochemical Properties	EC Method A.15	Auto-flammability	Rikabinol HB was determined not to auto-ignite below 400°C.
4.13	Rikabinol HB Physicochemical Properties	EC Method A.10	Flammability	The test substance, Rikabinol HB, was found not to be highly flammable.
4.14	n/a	n/a	Explosiveness	Waived. In accordance with column 2 of REACH annex VII the explosivity test does not have to be conducted as HBPA contains no chemical groups associated with explosivity
4.15	n/a	n/a	Oxidising properties	Waived. 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.
4.17	n/a	n/a	Stability in organic solvents	Waived. In accordance with Column 2 adaptation statement of REACH Annex IX, information requirement section 7.15, this study does not need to be conducted since the stability in organic solvents is not considered critical
4.21	n/a	n/a	Dissociation constant	Waived. In accordance with section 1 of REACH Annex XI, the dissociation constant study does not need to be performed because the substance does not contain any ionic structure.
4.22	n/a	n/a	Viscosity	Waived. In accordance with section 2 of REACH Annex XI, the viscosity does not need to be performed as the substance is a solid.
