Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Results and discussion

Melting / freezing point
Key result
Melting / freezing pt.:
>= 116 - <= 116.9 °C

Any other information on results incl. tables

Beginning / final stage of melting:

Exp. 1, 2 and 3: 116.0 / 116.9°C

Exp. 4: 116.1 / 116.9°C

As the difference between the beginning and the final stage of melting is not within the limits of accuracy of the method, a melting range was reported for the substance.

Applicant's summary and conclusion

Conclusions:
Using the capillary/metal block method according to OECD TG 102, a melting range of 116.0 - 116.9°C was determined for Cholesteryl acetate.
Executive summary:

Using the capillary/metal block method according to OECD TG 102, a melting range of 116.0 - 116.9°C was determined for Cholesteryl acetate. The result is the mean of 4 experiments.
