Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Bitter orange oil is a mixture of substances 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 mentions in chapter R7.1.2.3, that «Melting points are not normally carried out for mixtures ». 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 oil after 60 hours at various temperatures.

Applicant's summary and conclusion
- Conclusions:
- Bitter orange oil is a clear mobile liquid at 20 degrees Celsius and a clear mobile liquid with wax precipitate at -30 degrees Celsius.
- Executive summary:
Bitter orange oil is a mixture of substances 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 mentions in chapter R7.1.2.3, that «Melting points are not normally carried out for mixtures ». 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 oil after 60 hours at various temperatures.
Bitter orange oil was found to be a clear mobile liquid at 20 degrees Celsius and a clear mobile liquid with wax precipitate at -30 degrees Celsius.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
