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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Attempts to dry were made which resulted in decomposition on heating under vacuum.
Drying under nitrogen removed most of the water, but the boiling point test showed evidence of some residual water.
Study valid, but academic as substance is always supplied in water. - Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Principles of method if other than guideline:
- sample of cocamidopropyl PG-dimonium chloride phosphate was analysed by Thermogravimetric Analysis (TGA) in order to determine the boiling point of the dried material.
- GLP compliance:
- no
- Type of method:
- other: Thermogravimetric analysis
- Specific details on test material used for the study:
- Chemical Name Cocamidopropyl PG-Dimonium Choride Phosphate
CAS# 83682-78-4
EC# 280-518-3
Physical State liquid (on receipt - dried under nitrogen)
Sample ID 53461J16 - Key result
- Boiling pt.:
- > 246 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- ambiguous
- Conclusions:
- Attempts to dry were made which resulted in decomposition on heating under vacuum.
Drying under nitrogen removed most of the water, but the boiling point test showed evidence of some residual water.
Study valid, but academic as substance is always supplied in water.
Reference
The first boiling point of the sample is 72°C (average) and is mostly likely a small amount of remaining water in the sample after drying.
The largest boiling component had an average boiling point of 248°C and is not completely resolved from a higher boiling component. This is
reported as the boiling point. Variability of the replicates may be caused by inhomogeneity in the dried sample.
Maximum temperature reached was 500 C; no major exotherm seen.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
