I think you may be right- here is what I found on their website:
How Does Sweet PDZ Work?
Sweet PDZ is extremely effective at neutralizing and removing ammonia and odors, because of its two special properties:
1) Adsorption - Which is the sticking of the ammonia gas molecule to the surface of the Sweet PDZ granule. When the Sweet PDZ granules desorb, or dries out, the ammonia odor molecule is driven off the surface of the mineral as nitrogen. This is why spent (used) bedding material that includes Sweet PDZ, works so well as a slow release fertilizer or as an enhancement to composting.
2) Cation Exchange Capacity (CEC) - This is the liquid exchange aspect of Sweet PDZ’s odor neutralizing process. A sodium or potassium cation from the zeolite granule hydrolyzes (goes to liquid/urine) and the ammonium is exchanged and then becomes part of the Sweet PDZ granule. This liquid exchange works because the Sweet PDZ granules are always holding water.
The Bottom Line: Sweet PDZ captures, neutralizes and eliminates harmful ammonia and odors, and it does so through its natural chemistry, not by covering up the odor with a perfume or masking scent.
