Endpoint summary
Administrative data
Description of key information
The liquid substance is to be classified as flammable liquid category 2.
There are no further classification requirements for the submission substance with regard to physico-chemical properties.
Relevant key information is given in the endpoint summaries on the respective properties.
For a summary and conclusion with regard to overall physical hazards and respective classification and labelling requirements, see below!
Additional information
A full set of physico-chemical information is available with many of the essential parameters determined according to established testing guidelines. Classification issues are discussed in the relevant endpoint summaries in more detail. Here, only a brief summary is given:
Because of a flash point <23 °C (6.5 °C, see section 4.11) and an initial boiling point above 35 °C (104 °C, see section 4.3), according to Regulation (EC) 1272/2008 (CLP Regulation) n-valeraldehyde has to be classified as flammable liquid Cat. 2.
Pyrophoric properties as well as formation of flammable gases in contact with water can be excluded based on experience from the handling and use of the substance.
With regard to self-heating, according to (1) "In general, the phenomenon of self-heating applies only to solids. The surface of liquids is not large enough for reaction with air and the test method is not applicable to liquids. Therefore liquids are not classified as self-heating."
With regard to classification for self-reactiveness, according to CLP, Annex I, 2.8.4.2. "The classification procedures for self-reactive substances and mixtures need not be applied if:
(a) There are no chemical groups present in the molecule associated with explosive or self reactive properties. Examples of such groups are given in Tables A6.1 and A6.2 in Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria;”
This applies for the submission substance.
Overall, the substance has to be classified as flammable liquid Cat. 2. No other classification requirements with regard to physical hazards do exist.
