2-imino-1-methylimidazolidin-4-one

Flammability

Link to relevant study record(s)

Reference

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

November 1999

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

test procedure in accordance with generally accepted scientific standards and described in sufficient detail

Qualifier:

equivalent or similar to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Principles of method if other than guideline:

The test methods are described in another document. This does not impair the conclusion of the test results.
The principles of the test methods including their deviations to the guideline are described in detail in the field "any other information on materials and methods".

GLP compliance:

not specified

Key result

Test procedure:

burning time (test type not further specified)

Remarks on result:

other: the substance ignites shortly but terminates quickly

1. Creatinine could be ignited by the 1000 °C hot platin wire, which was dipped for 5 seconds into the dried substance. Creatinine was melting, changed its colour into brown and the ignition process was terminated rapidly ("Bewertungszahl 2").

2. Creatinine could not be ignited by an open flame hold onto the substance for approx. 10 -15 seconds ("Bewertungszahl 1"). Creatinine was melting and was deposed but could not be ignited.

3. Creatinine could not be ignited when put into a red heated iron bowl for 60 seconds ("Bewertungszahl 1"). A mixture of potasium nitrate and Creatinine was burning off calmly after the same treatment ("Bewertungszahl 2"). "Gesamt-Bewertung: Bewertungszahl 1,5"

Interpretation of results:

GHS criteria not met

Conclusions:

Creatinine can be ignited but it is melting and burning off calmly. Therefore Creatinine is considered to be not highly flammable.

Executive summary:

Three tests were conducted according to guidelines similar to guideline A.10.

Creatinine was dried before testing. The dried Creatinine could be ignited by the 1000 °C hot platin wire, which was dipped for 5 seconds into the dried substance. Creatinine was melting, changed its colour into brown and the ignition process was terminated rapidly ("Bewertungszahl 2").

In a second test approx. 200 mg of Creatinine were put into a flat iron bowl and heated with an open gas flame burner for 10 -15 seconds. Creatinine was melting and was deposed but could not be ignited.

In a third test approx. 150 mg Creatinine and a 1:1 mixture of Creatinine with potassium nitrate were put into a red heated iron bowl for 60 seconds. Creatinine itself could not be ignited, but the mixture with potassium nitrate was burning of calmly.

Therefore it is concluded that Creatinine could be ignited but is not highly flammable.

Description of key information

Creatinine can be ignited but it is melting and burning off calmly.

Therefore Creatinine is considered to be not highly flammable.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

The tests were conducted according to guidelines similar to guideline A.10.

Creatinine was dried before testing. The dried Creatinine could be ignited by the 1000 °C hot platin wire, which was dipped for 5 seconds into the dried substance. Creatinine was melting, changed its colour into brown and the ignition process was terminated rapidly ("Bewertungszahl 2").

In a second test approx. 200 mg of Creatinine were put into a flat iron bowl and heated with an open gas flame burner for 10 -15 seconds. Creatinine was melting and was deposed but could not be ignited.

In a third test approx. 150 mg Creatinine and a 1:1 mixture of Creatinine with potassium nitrate were put into a red heated iron bowl for 60 seconds. Creatinine itself could not be ignited, but the mixture with potassium nitrate was burning of calmly.

Therefore it is concluded that Creatinine could be ignited but is not highly flammable.

Justification for classification or non-classification

Due to the test result Creatinine can be excluded from the hazard class “flammable solids”and does not have to be classified.
