Description of key information
DEIPA is not highly flammable when in contact with air at room temperature or when in contact with water
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
According to an expert regulatory report, DEIPA is stable in air in the absence of moisture and is "Not expected to be flammable due to [its] low vapour pressure” (NICNAS, 2009). Furthermore, industry experience (manufacture and use) and the available studies conducted to date, including auto-flammability and toxicity testing in laboratory animals (by oral, dermal and inhalation routes) demonstrates that DEIPA does not spontaneously ignite after coming into contact with air at room temperature.
DEIPA is hygroscopic and fully soluble in water (NICNAS, 2009). Industry experience (manufacture and use) and the available studies conducted to date, including water solubility, acute aquatic toxicity testing and toxicity testing in laboratory animals (by oral, dermal and inhalation routes) demonstrates that DEIPA does not spontaneously ignite after coming into contact with water.
On evaluation of its structural features, DEIPA does not contain any chemical groups that might lead to spontaneous ignition shortly after coming into contact with air (pyrophoric) or water (flammability), or to evolve flammable gases. No metals, transition metals, boron or silicon are present in DEIPA. Moreover, the flash point of DEIPA was measured at 192 °C (Atwal, 2012b) and the EU CLP regulations state that a “flammable liquid means a liquid having a flash point of not more than 60 °C”.

Justification for classification or non-classification
Based on the information provided above (notably a flash point >60oC), classification and labelling according to the EU CLP regulations is not warranted.
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).
