SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: Batch no: 06386
- Expiration date of the lot/batch: June 2020
- Purity test date: July 2017

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
The test item was stored in a closed vessel at 3.3 -8.0 °C away from light.
Except for the times below:
At 24. Jul. 2017 between 15:36 – 16:04 o’clock the temperature was 8.0 -9.0 °C.
At 02. Oct. 2017 between 10:40 – 11:25 o’clock the temperature was 6.1 – 10.2 °C.
At 08. May 2018 between 09:20 – 09:43 o’clock the temperature was 5.1 – 10.8 °C.

Remarks on result:
no flash point - measurement carried out until boiling temperature

 Pre-Test for Safety

A safety test was performed in study 17071806G906 determination of the boiling point. A small amount of the test item was heated in a test tube in an aluminium block with a Bunsen burner.

Table     Observations Pre-test

Observation

Temperature

Bubbles rising up.

118 °C

Lots of bubbles rising up.

121 °C

Test item starts to pulsate on the surface of the liquid even with capillary. Boils suddenly up (superheating)

Test terminated for safety reason.

The measurement was conducted at 07. Jun. 2018.

*As overboiling was observed at the temperature of 110.7 °C, the pre-test was stopped and no main test could be performed.

No flash point was found up to the temperature of 110.7 °C.

Interpretation of results:
GHS criteria not met
Conclusions:
No flash point found up to 110.7°C (EU.Method A.9)
Executive summary:

No flash point can be stated for the test item as the test item started to boil at this temperature under the test conditions.

No flash point was found up to the temperature of 110.7 °C.

Description of key information

flash point according to EU A.9

Key value for chemical safety assessment

Additional information

No flash point can be stated for 70% w/w Phytic acid (made from dermofeel PA) as the test item started to boil at this temperature (110.7°C) under the test conditions.
