Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

A test substance is considered an oxidizing substance when a mixture of the substance and cellulose in a 1:1 ratio (by mass) spontaneously ignites or the mean pressure rise time of the mixture is less than or equal to mean pressure rise time of a 1:1 reference mixture (by mass) of 65% aqueous nitric acid and cellulose


The test substance is a yeast extract and contains approximately 50% water. It is therefore impossible that the test substance will act as an oxidizing substance.


In conclusion,Saccharomyces cerevisiae, Extract (Springer 0204/0-LQ-L) has no oxidizing properties

Justification for classification or non-classification

Based on the available information Saccharomyces cerevisiae, ext. does not need to be classified for oxidising properties according to DSD or GLP.
