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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Endpoint:
- surface tension
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because water solubility is below 1 mg/L at 20°C
- Justification for type of information:
- The water solubility is below 1 mg/L (see section 4.8). Testing is therefore not required according to Annex VII (section 7.6) of Regulation (EC) No 1907/2006.
Cross-reference
- Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2011
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Remarks:
- Test procedure according to method of Analytical Expert Group ETAD (Ecological and Toxicological Association of Dyes and Organic Pigment Manufacturers).
- Principles of method if other than guideline:
- Determination of water solubility.
The analytical method for the determination is in agreement with the method that was agreed upon at the Analytical Experts Meeting of ETAD (Basel) on January 12, 2005. - Type of method:
- flask method
- Key result
- Water solubility:
- 10 µg/L
- Temp.:
- 21 °C
- pH:
- ca. 6
- Remarks on result:
- other: The determination of water solubility was conducted at ambient temperature (21-22 °C)
- Details on results:
- The value above represents the mean from 2 determinations (sigma=1). See below for indidividual results.
- Conclusions:
- Interpretation of results (migrated information): insoluble (< 0.1 mg/L)
The test substance has a water solubility of 10 µg/L. - Executive summary:
The water solubility was determined by UV-Vis analysis of the dissolved test substance amount in 30 mL water according to the method that was agreed upon at the Analytical Experts Meeting of ETAD (Basel) on January 12, 2005.
The test substance has a water solubility of 10 µg/L (21 -22 °C).
Individual results:
| Absorption (d = 10 cm) | µg/L | pH |
a1 | 0.0079 | 11 | 6.1 |
a2 | 0.0064 | 9 | 5.9 |

Applicant's summary and conclusion
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.
