Description of key information
Liquid: The substance is a 25% solution in water, therefore performing a study is scientifically unjustified.
Solid: The test item disodium tetrasulfide (EC no. 215-686-9) is miscible in a 1 : 1 ratio mixture (w/w) with water (at 20 °C).
Key value for chemical safety assessment
- Water solubility:
- 1 000 mg/L
- at the temperature of:
- 20 °C
Additional information
Solid: The water solubility of the test item disodium tetrasulfide (EC no. 215-686-9) was determined according to OECD guideline no. 105 [adopted on 27 July 1995] and EU test method A.6 [Directive 92/69/EEC, Official Journal L 383 A 1992] with the modified flask method. Principle of the flask method: The substance is dissolved in water at a temperature somewhat above the test temperature, such that a portion of the substance remains undissolved. When saturation is achieved, the mixture is cooled and kept at the test temperature until equilibrium is reached. Subsequently, the mass concentration of the substance in the aqueous solution, which must not contain any undissolved particles, is determined by a suitable analytical method.
The test item disodium tetrasulfide (EC no. 215-686-9) is miscible in a 1 : 1 ratio mixture (w/w) with water (at 20 °C).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.
