Care for your pet like Vince the Vet

The following are chemical additives found in many pet supplements and food.

It is not meant to be an exhaustive list and so if you see an ingredient you don't recognise on a product label, be sure to research it online.

It's also safe to assume, that when such additives are included, it is for the benefit of the manufacturer concerned and not the pet (either to facilitate production or to create a significantly cheaper product).


Some of the additives are included more than once because they have multiple uses.

Artificial Colours:  

E131 Patent Blue V (FD&C Blue 2)

E129 Allura Red AC (FD&C Red 40)

E102 Tartrazine (FD&C Yellow 5)

Titanium dioxide

Artificial Preservatives:

E320 Butylated hydroxyanisole (BHA)

E321 Butylated hydroxytoluene (BHT)

E282 Calcium propionate

E330 Citric acid

E325 Sodium lactate

E237 Sodium propionate


E310 Propyl gallate

Sodium benzoate - now banned in the UK

Sodium propionate

Artificial Sweeteners:


Anti-caking Agents:

E551 Silicon dioxide

E572 Magnesium stearate

Corn / Maize Derivatives:

These modified starch products are used as thickeners, stabilizers, binders and texturizing agents in many pet foods.

E1404 Oxidized starch

E1410 Monostarch phosphate

E1412 Distarch phosphate

E1413 Phosphated distarch phosphate

E1414 Acetylated distarch phosphate

E1420 Acetylated starch

E1422 Acetylated distarch adipate

E1442 Hydroxy propyl distarch phosphate

E1450 Starch sodium octenyl succinate

Other corn-derived food additives used include corn syrup solids, corn gluten meal, corn protein concentrate, corn oil, and dextrose. 

And so many pet foods contain quite a bit of corn in various derivative forms beyond whole corn kernels.
