EC number: 283-294-5
CAS number: 84604-16-0
Extractives and their physically modified derivatives such as tinctures, concretes, absolutes, essential oils, oleoresins, terpenes, terpene-free fractions, distillates, residues, etc., obtained from Saccharomyces cerevisiae, Saccharomycelaceae.
- Electrostatic spark ignition testing:
EMI ("Energie Minimale d'Inflammation" / minimal energy
needed to inflame) was estimated as >1J.
- Pyrotechnic ignition testing at 10 kJ:
dP/dt max = 199 bar/s
Pmax = 7.1 bar
Kst = 54 bar.m/s
Class of dust explosion: St 1
Dried fine (<63 µm median size) powder Yeast extract is
not explosive when submitted to electrostatic spark inflammation.
The minimal energy needed to inflame was estimated as
>1J. Pyrotechnic ignition testing at 10 kJ showed pressure rise speed of
199 bar/s, Pmax = 7.1 bar and a St 1 class (minimal possible of 3 hazard
classes) for dust explosion.
