Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- plate method
- Key result
- Surface tension:
- 53 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- A surface tension of 53 mN/m at 20 °C was determined for HPP 12879 -1.
- Executive summary:
The surface tension according to OECD 115 of an aqueous solution (1 g/L) of HPP 12879 -1 at 20 °C was determined using a plate tensiometer. A commercially available tensiometer based on the plate method has been used to measure the force which is required to withdraw a horizontally suspended plate from the surface of the test solution. The surface tension was determined in a mixture of 0.9999 g test item in 1 L demineralized water (= approx. 1 g/L) at 20 °C. Since the test item was not completely soluble at 1 g/L the suspension was stirred for 24 hours and filtered through 0.45 μm Chromafil Xtra PET 45/25 filter. Clear solutions were obtained after filtration. A mixture of 72 mL filtrate and 8 mL deionized water was prepared and used for the measurement.
A surface tension of 53 mN/m was determined for HPP 12879 -1.

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.
