Appearance: Slightly yellow powder
COMPOSITION:
Total FOS:96% expressed as dry matter
1-Kestose (GF2): 37.1% expressed as dry matter
Nystose (GF3): 50.5% expressed as dry matter
1F-Fructofuranosylnystose (GF4): 12.4% expressed as dry matter

- Temp.:
- ca. 50 °C
- Vapour pressure:
- <= 0.001 Pa
- Remarks on result:
- not determinable because of methodological limitations
- Key result
- Test no.:

- Temp.:
- ca. 20 °C
- Vapour pressure:
- < 0.001 Pa
- Remarks on result:
- not determinable because of methodological limitations
- Key result
- Vapour pressure:
- <= 0.001 Pa
- Conclusions:
- The vapour pressure of the test item was considered to be lower than 10-3 Pa at 80 °C and as a consequence largely lower than 10-3 Pa at 20 °C.
- Executive summary:
The vapour pressure of the test item was investigated in a study performed in accordance with EC A.4 method and OECD Guideline No. 104 using a dynamic method. The vapour pressure of the test item was considered to be lower than 10-3 Pa at 80 °C and as a consequence largely lower than 10-3 Pa at 20 °C.
Reference
The mass of sample weighed for each assay was reported in the table below. The sample was placed in a Knudsen effusion cell. Then the cell was placed in the apparatus.

* the loss of mass was not measured as no linear part was recorded.
For the assay No. 1 a small loss of weight, representing about 2% of the initial mass, was recorded at 50 °C but without any linear part. The slope of the loss of mass was not constant and decreased continuously until becoming close to zero.No degradation of the test item was observed after the experiment; the powder remained slightly yellow.
The temperature was increased up to 80 °C and the results were similar.
The loss of mass observed at the beginning of the assays is not significant and can correspond to the evaporation of volatile impurities or to the stabilisation of the mass.
Description of key information
The vapour pressure of the test item was investigated in a study performed in accordance with EC A.4 method and OECD Guideline No. 104 using a dynamic method. The vapour pressure of the test item was considered to be lower than 10-3 Pa at 50 °C and as a consequence largely lower than 10-3 Pa at 20 °C (OECD 104)
Key value for chemical safety assessment
- Vapour pressure:
- 0.001 Pa
- at the temperature of:
- 20 °C
Additional information
The value of 10-3 Pa corresponds to the minimal limit of pressure determined by the lab apparatus.
It was not possible to find another appropriate method to measure the vapour pressure of this multiconstituents substance with a relatively low vapour pressure (lower than 10-3 Pa).
The vapour pressure of the test item was determined in a study performed in accordance with standard methods, without deviations. The study is considered as reliable (Klimisch 1) and is selected as a key study for the endpoint.
