Endpoint:
explosiveness, other
Study period:
This study was conducted between 17 June 2017 and 01 August 2017
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties
Justification for type of information:
Performance of the Prediction
The structure of the test item was assessed for chemical groups that imply explosive properties.  Examples of such groups are C-C unsaturated, C-metal, N-metal, contiguous oxygen atoms, contiguous nitrogen atoms, N-halogens, O-halogens, N-O.  Examples of these groups are given below.
Structural Features              Examples
C-C unsaturated                     Acetylenes, acetylides, 1,2 - dienes
C-metal, N-metal                   Grignard reagents, organo-lithium compounds
Contiguous oxygen atoms       Peroxides, ozonides
Contiguous nitrogen atoms      Azides, aliphatic azo compounds, diazonium salts, hydrazines, sulphonyl hydrazides
N-halogens                            Chloramines, fluoroamines
O-halogens                            Chlorates, perchlorates, iodosyl compounds
N-O                                      Hydroxylamines, nitrates, nitro compounds, N oxides, 1,2-oxazoles
Full structural details are given in Bretherick’s Handbook of Reactive Chemical Hazards, 7th Edition, Academic Press, 2007.

Evaluation of Data
If there are no structural alerts within the structure then the explosive properties can be predicted negative.
Materials that have an oxygen balance more negative than -200 are not considered to pose an explosive risk.
If the exothermic decomposition energy is less than 500J/g and the onset of exothermic decomposition is below 500 °C, testing is not required.

Results
There were no structural alerts within the chemical structure of the test item.

Conclusion
Based on the chemical structure of the test item the result for the explosive properties has been predicted negative.



Qualifier:
according to guideline
Guideline:
EU Method A.14 (Explosive properties)
Conclusions:
Based on the chemical structure of the test item, the result for the explosive properties has been predicted negative.
Executive summary:

The hazardous physico-chemical properties of 4,4'-Isopropylidenediphenol, oligomeric reaction products with 1-chloro-2,3-epoxypropane, reaction products with triethylenetetramine have been determined.  

Explosive Properties. Predicted negative based on the chemical structuresof the test item, using a procedure designed to be compatible with Method A.14 Explosive Properties of Commission Regulation (EC) No 440/2008 of 30 May 2008.
