Description of key information
Flammability (solids)
Under the conditions of an EU Method A.10 guideline study, Dioctyltin mercaptopropionate is considered ‘not highly flammable’.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Flammability (solids)
The flammability of the test material was determined in accordance with the standardised guideline EU Method. A.10. The study was awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch et al. (1997).
The flame of a gas burner was applied to one end of the test material train for 2 min. If the substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within four minutes test period, then the substance should not be considered as highly flammable and no further testing is required.
The test material melted on contact with the flame and blackened. The molten substance burned in contact with the flame but without it stopped combustion immediately. No further testing was required.
Under the conditions of this study, the test material is considered ‘not highly flammable’.
Pyrophoricity and contact with water
In accordance with Section 1 of Annex XI of Regulation (EC) No. 1907/2006 (REACH), it is considered justified to omit the Flammability (Contact with Water) and Pyrophoric Properties of Solids and Liquids studies, also required under section 7.10 of Annex VII, on the basis that the testing does not appear to be scientifically necessary. The chemical structure of the test material contains no groups which would indicate potential reactivity with water or pyrophoric properties. In addition, experience of handling the material and the known chemical and physical properties of the substance suggest that it is not pyrophoric and is not flammable in contact with water.
Justification for classification or non-classification
Dioctyltin mercaptopropionate is not "highly flammable" according to the criteria of the EEC-Directive 92/69 EEC, A.10 "Flammability (solids)", has no pyrophoric properties and does not contain groups that might lead to a reaction with water or damp air, leading to the development of dangerous amounts of gas or gases which may be highly flammable.
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does not require classification with respect to flammability.
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).
