Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2009-10-23
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The pendant drop method used has been compared to the ring method OECD 115 and gave good correlation

Materials and methods

Principles of method if other than guideline:
Pendant drop
A syringe was filled with approximately 10 ml of the solution and was attached to the instrument. The solution formed a drop on the tip of the needle.
This drop was examined optically by the software. The surface tension was calculated by the shape of the drop.
The pendant drop method used has been compared to the ring method OECD 115 and gave good correlation
GLP compliance:
no
Type of method:
other: pendant drop, Perstorp A1577
