Applicant's summary and conclusion

Conclusions:
The bulk density of the test substance was determined where the pour density and the tap density were both 0.78 g/mL.
Executive summary:

The density of the test substance was determined by methodology appropriate for its physical state according to CIPAC MT-159, OECD TG 109, OPPTS 830.7300 and ASTM D727. An appropriate amount of the test substance was weighed in order to fill 90% of a 50 mL glass cylinder. The test substance was poured into the cylinder, levelled off and the initial volume measured to the nearest 1 mL. The bottom of the cylinder was then raised 25 mm and allowed to drop until a total of 100 taps were made and a second volume measured and recorded. The pour density of lactitol was its weight divided by the initial volume and expressed in g/mL. The tap density of lactitol was obtained by dividing the weight of the test substance by the second volume (g/mL). Both the pour density and the tap density of lactitol was 0.78 g/mL.
