Risk level on the Yenzo Scalemoderate?Based on EFSA's scientific assessment, 2008
EFSA (2008) found that intake in some population groups can exceed the tolerable weekly intake (TWI); the EU therefore cut the maximum use levels and removed some of these additives (Regulation (EU) 380/2012). This is what puts it at the middle level of the Yenzo Scale.

Is sodium aluminium silicate harmful?
In 2020 EFSA concluded that the safety of sodium aluminium silicate (E554) and potassium aluminium silicate (E555) could not be assessed, because only very limited data on their effects and insufficient information on their physical and chemical characterisation were available. EFSA asked for further data in line with the current guidance for evaluating additives.
Is INS 554 permitted in Vietnam?
Yes. Sodium aluminium silicate (INS 554) is listed in Appendix 1 of Circular 24/2019/TT-BYT, the list of additives permitted in food, with the function anticaking agent.
