The ingredients in denture cleaners would appear to be chemicals that would make the tablets kosher for passover. Apparently, kitniyos or chametz are not used.
Dilute sodium hypochlorite (i.e. a mild bleach) is the main constituent of several brands of denture cleanser. Other ingredients include such chemicals as:
- sodium bicarbonate – or baking soda, which alkalizes the water, cleaning the dentures.
- citric acid – removes stains.
- sodium perborate
- sodium polyphosphate
- potassium monopersulfate – cleaning and bleaching agent
