Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The surface tension of the aqueous solution at 20 °C is 62. mN/m.
Key value for chemical safety assessment
- Surface tension:
- 62
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
The determination of the surface tension was carried out on the test item as supplied by the sponsor, with a Kruess Processor Tensiometer K12 using the OECD harmonised ring method.
The mean value of the last ten measurements was recorded. The data was corrected automatically by the apparatus according to Zuidema and Waters.
The measured value was found to be 62 mN/m.
As the surface tension value was higher than 60 mN/m, Reactive Blue 220 is not classified as surface active.
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.
