Worst case selection

Help

I have 2 products, API’s Na Bicarbonate, Sodium Citrate, Citric Acid and Tartaric Acid and also uses 70% dextrose are granulating solution. The other NaCl, KCl, Sodium Citrate, Dextrose. These products use the same equipment. All ingredients are highly soluble in water. Toxicty is low. Which product and ingredient, do I take as the worst case product.

The first product label claim is Sodium, Citrates and Tartrate. The second is Na, K, Dextrose and citrates.

What guiding analyte do I use?

If I use Na or citrates. It is present in both
The solubilities are as follows:

Active Ingredient / Solubility in water / Labelclaim (API - mg/g )
Sodium Bicarbonate/ 8,8g/100ml /429
Sodium Citrate Dihydrate/ 72g/100ml /153
Citric Acid Anhydrous/ 133g/100ml /176
Tartaric Acid/ 133g/100ml /215
Dextrose Monhydrate/ 90g/100ml /754
Sodium Citrate/ 72g/100ml /112
Sodium Chloride/ 33g/100ml /77
Potassium Chloride/ 34g/100ml /58

What would be my rationale for choosing and ingredient?
