[0086] To show how the flowability of the composition according to the present invention was improved, the flowability was measured as described in the following.

Flowability Measurement

[0087] The FT4 Powder Rheometer® (Freeman Instruments, UK) is an instrument able to characterize the rheology, or flow properties, of powders. One of the test that the above-mentioned instrument can perform is the so called “Aeration Test”, where the cohesive forces of the analyzed powder are quantified. Cohesive forces are a combination of Van der Waal's and electrostatics, and tend to “bond” particles together. Therefore, the higher the measured cohesive forces are, the less flowable the analyzed powder is.

[0088] The measured resistance to flow, the Aerated Energy (AE), quantifies the strength of the cohesive forces.

[0089] For powders with weak cohesive forces, the Aerated Energy tends towards zero as the powder becomes fully aerated. Powders with moderate to high cohesion will exhibit a reduction in flow energy when aerated, but to a much lesser extent. In these cohesive powders, the tensile forces are too strong for the air to overcome and the particles do not separate.

[0090] The composition of Example 1 did show a total Aerated Energy value of 750 mJ when the air velocity was set at 6 mm/s while the composition of the comparison Example (Example 2) did show a value of 1300 at the same air velocity conditions.

[0091] The results are to be seen also in the graph.

Method:

[0092] A standard powder volume is poured into a specially designed sample holder (Freeman Technology, UK). The sample holder features a porous bottom, which allows air to pass through and aerate the powder contained in the cylindrical sample holder, in a controlled way.

[0093] After sample preparation, the air flow is initiated and a rotating propeller is lowered into the aerated powder.

[0094] A specific hardware unit is then providing increasing air speed.
