- Conclusions:
- The maximum burning rate of the mixtures of the test item and cellulose (1.10 mm/s) was lower than the maximum burning rate of the reference mixture of cellulose and barium nitrate (1.57 mm/s).
Due to the fact that the mixture of the test item with cellulose burned slower compared to the reference mixture, or the flame extinguished before the pre-burning phase was finished, it was concluded that the test item has no oxidizing properties. - Executive summary:
The purpose of this study was the determination of the oxidizing properties of the test item, bismuth subsalicylate, according to the European Commission Regulation (EC) No. 440/2008, Part A: Methods for the determination of physico-chemical properties. A. 17. Oxidizing properties of solids.
The maximum burning rate of the mixtures of the test item and cellulose (1.10 mm/s) was lower than the maximum burning rate of the reference mixture of cellulose and barium nitrate (1.57 mm/s).
Due to the fact that the mixture of the test item with cellulose burned slower compared to the reference mixture, or the flame extinguished before the pre-burning phase was finished, it was concluded that the test item has no oxidizing properties.
Reference
Preliminary Test
Three test mixtures with the test item and cellulose 2:1 did not burn with a flame after the ignition source was removed. The mixtures continued to smoulder for approximately 7 minutes.
Three test mixtures with barium nitrate/cellulose 2:1 burned down completely in 75 s, 74 s and 76 s, respectively.
Due to the results of the preliminary test the full test had to be performed.
Three tests were performed for the reference mixture (barium nitrate and cellulose) with 40, 50, 55, 60 and 70 wt. % oxidizer (barium nitrate). The results are shown in the following table:

The highest burning rate 1.57 mm/s was found for the mixture with 60 wt.% oxidizer.
Mixtures of the test item with cellulose were prepared with 10, 15, 20, 30, 40, 50, 70, 80, 90 and 100 %.

Due to the fact, that the maximum burning rate of the mixtures of the test item with cellulose is lower than the burning rate of the reference mixture, six additional tests for the test item mixture were performed for the mixtures with the highest burning rates of 10, 15 and 20 wt. % of the test item.

The maximum burning rate of the mixtures of the test item and cellulose (1.10 mm/s) was lower than the maximum burning rate of the reference mixture of cellulose and barium nitrate (1.57 mm/s).
Description of key information
Bismuth citrate is not oxidising.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
A study was conducted to determine the oxidising properties of the test item, bismuth citrate, according to the European Commission Regulation (EC) No. 440/2008, Part A: Methods for the determination of physico-chemical properties. A. 17. Oxidizing properties of solids.
Due to the fact that the mixture of the test item with cellulose burned slower compared to the reference mixture, or the flame extinguished before the pre-burning phase was finished, it was concluded that the test item has no oxidising properties.
Justification for classification or non-classification
The substance has been shown to have no oxidising properties therefore it is not classified.
