Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Al(H2PO2)3 should be regarded as a non surface-active material as the measured surface tension at 1 g/L is higher than 50 mN/m.
Key value for chemical safety assessment
- Surface tension:
- 71.1
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
From the experimental data obtained according to the guideline A.5 in Official Journal L 383 Part A, it can be concluded that the surface tension of the aqueous solutions at concentration of 1000, 500 and 100 mg/L at 20 °C are 71.1, 72.6 and 73.1 mN/m respectively. The value mesured at 1 g/L is considered as the reference. According to the interpretation of the results suggested in the A.5 official method, the sample Pholite IP-A should be regarded as a non surface-active material as the measured surface tension at 1 g/L is higher than 50 mN/m.
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.
