Description of key information
The water solubility of Dowfax 8390 is estimated to be > 1000 g/L. The test material may be considered as "very highly soluble" in water.
Key value for chemical safety assessment
- Water solubility:
- 1 000 g/L
- at the temperature of:
- 20 °C
Additional information
The water solubility of DOWFAX 8390 Solution Surfactant (Solids) was estimated following the preliminary range-finding test procedures of OECD Guideline No. 105. Approximately 0.1 g of the test material was completely dissolved in 0.1 mL ultrapure water after mixing overnight (approximately 16 h); therefore, according to the OECD Guideline 105, the water solubility of the test material is estimated to be > 1000 g/L. As such, the test material may be considered as "very highly soluble" in water. The test material components are ionizable (anionic), where the acid dissociation constants (pKa) for the ionizable sulfonate groups are estimated to be <0. Therefore, water solubility is not expected to be highly variable over the pH rage relevant to human and environmental exposures.
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).
