Materials and methods

Test guideline
Qualifier:
according to
Guideline:
other: internal method : see protocol below
Principles of method if other than guideline:
The test item is a mixture of constituents and transition from liquid to solid will not be sharp. The „Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance” from ECHA (2008), mentioned that "Melting points are not normally carried out for mixtures“. In addition, according to column 2, point 7.2 of Annex VII of Regulation (EC) 1907/2006 (REACH), "The study does not need to be conducted below a lower limit of -20°C“.
Therefore it is recommended in the EFFA/EFEO guideline „The Registration for REACH of Natural Complex Substances used as Fragrance Ingredients” to describe the state of the essential after equilibrium at +20°C, +5°C and -20°C.
GLP compliance:
no
Type of method:
other: visual observation after equilibrium at 3 temperatures
