Applicant's summary and conclusion
- Conclusions:
- The melting point of the test substance was 150.6°C.
- Executive summary:
The melting point of the test substance was measured by the capillary technique using the Stuart SMP 2Q Melting Point Apparatus based on the procedures described in OPPTS 830.7200, OECD TG 102, and EEC method A1 methods. The temperature (°C) at which the test substance was observed to melt was recorded as the melting point. This procedure was repeated with the test substance to obtain two measurements. The melting point of lactitol was 150.6°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
