Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
melting point/freezing point
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
other:
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
Supporting literature data on an analogue shows that the freezing point is expected to fall much below -20°C.
Therefore NO new experimental study is deemed necessary for the parent substance.
Reason / purpose for cross-reference:
data waiving: supporting information
Endpoint:
melting point/freezing point
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
supporting study
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
secondary literature
Remarks:
Literature data. Original source not checked. No data on substance composition.
Justification for type of information:
Read-across is justified as data relates to mixture of isomers (cis/trans) of the present dossier substance (monoconstituent, cis-isomer).
Qualifier:
according to guideline
Guideline:
other: ASTM D-1015
GLP compliance:
no
Melting / freezing pt.:
< -50 °C
Data is for mixture of cis and trans isomers.
Conclusions:
Freezing point <-20°C.
No further testing necessary.
Executive summary:

Published literature data for submission to the US-EPA provides a limit value of <-50°C for the substance 4-tert-Butylcyclohexyl acetate, with reference to guideline.

Read-across is justified as source data is available for mixture of cis and trans isomers, and target contains mainly (>80%) the cis isomer.

Description of key information

Freezing point <-20°C.

No further testing necessary.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-20 °C

Additional information

No data is available on the substance itself. However, published literature data on an analogue (mixture of isomers) provides a limit value of <-50°C. Despite reliability could not be assigned, this data is considered sufficient for purpose, as no further testing is required below -20°C. As no significant difference is anticipated with the present dossier monoconstituent substance, the read-across is considered justified.

As risk assessment requires a figure in the above "key value" box (no < or > sign accepted), this threshold value will be used as default data for CSA purpose.
