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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2014
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: GLP, guideline study.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Surface tension:
- 59.7 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension at a nominal concentration of 1 g/L was 59.7 mN/m at 20 deg. C.
- Executive summary:
The test substance is subject to rapid hydrolysis, therefore the results may be representative of both tris dipropylene glycol phosphite and the main hydrolysis product - dipropylene glycol. The results of both test runs were very close and all samples were in the range of 59.5-60.0 mN/m at 20 deg. C. It is worth noting that the dipropylene glycol dossier reports a surface tension value of 71.4 mN/m at 22 deg. C; very close to the results of this test which might be illustrative of the test material hydrolysing to large extent during this study.

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.
