Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
March 2001
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Study was carried out according to generally valid and internationally accepted testing guidelines and under GLP. The identity is not fully known. This is acceptable because the endpoint can be waived because of decomposition.
Qualifier:
according to guideline
Guideline:
EU Method A.2 (Boiling Temperature)
Qualifier:
according to guideline
Guideline:
OECD Guideline 103 (Boiling point/boiling range)
GLP compliance:
yes
Type of method:
differential scanning calorimetry
Specific details on test material used for the study:
Test item: Aquapel 364 Sizing Agent
Physical form: Amber waxy solid
Reference: Y09622/002/001
Start bottle no. 198576
The identity and purity of the test substance were not examined in this study but are assumed to be the
responsibility of the Sponsor.
Decomposition:
yes
Decomp. temp.:
> 200 - < 310 °C

The scans show a broad exothermic peak between 200°C and 300°C. This exothermic behaviour is characteristic of decomposition and this was confirmed by the presence of dark brown residue (approximately 94% of the original sample mass) at the end of each scan. The third scan showed exothermic activity at ca. 210°C - 310°C. No boiling was observed in any of the scans.

Conclusions:
84989-41-3, AKD,
The test substance decomposes without boiling with decomposition occurring above 200°C

Description of key information

The test substance decomposes without boiling with decomposition occurring above 200°C

Key value for chemical safety assessment

Additional information

The study was carried out on CAS 84989-41-3 according to generally valid and internationally accepted testing guidelines and under GLP. The endpoint can be waived because of decomposition.
