- Remarks on result:
- other: Essential oil of Citrus sinensis (Rutaceae) peel, terpene-free is a yellow clear liquid at 20 degrees Celsius and a liquid after 24 hours 17 min below -20 degrees Celsius.
- Conclusions:
- The freezing point of the substance is stated as : <-20°C (<253.15K)
- Executive summary:
Essential oil of Citrus sinensis (Rutaceae) peel, terpene-free 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 R.7.1.2.3, 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 at +5°C -if still a liquid the test has to be repeated at -20°C- rather than determining a transition temperature.
No freezing was observed when cooling down to and storing the substance at a temperature at -26.1°C for 24 hours 17 min.
According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, Annex VII, dated 18, December 2006 (and further amendments) by Commission Regulation the determination of the melting-/freezing point does not to be conducted below lower limit of -20°C.
Therefore the freezing point of the substance is stated as <-20°C.

The test item Essential Oil of Citrus (Rutaceae) peel, terpene-free was still unfrozen and liquid at -20°C. At -80 °C the test item was frozen.
At -80°C, the test item was frozen. According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, Annex VII, dated 18, December 2006 (and futher amendments) by Commission Regulation the determination of the melting-/freezing point does not to be conducted below lower limit of -20°C.
The freezing point of the substance is stated as <-20°C.
Description of key information
The freezing point of test item was stated as <-20°C. Test item is liquid at ambient temperature.
Key value for chemical safety assessment
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. It is considered as a key study.
After storage for one day at – 20 °C, the test item was still liquid. According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL (REACH), Annex VII, column 2 of section 7.2, the determination of the melting- / freezing point does not need to be conducted below a lower limit of - 20 °C. Therefore, the result is expressed as a limit value and cannot be retained as key data for purpose of CSA.
