Is e450iii vegan?

E450iii, also known by its common name tetrasodium diphosphate or tetrasodium pyrophosphate, is a synthetic food additive used primarily as an emulsifier, leavening agent, and buffering agent. It is produced through the thermal dehydration of disodium phosphate, which is prepared by reacting mineral-derived phosphoric acid with sodium carbonate or sodium hydroxide. Manufacturers frequently add it to commercially prepared bakery goods, refrigerated doughs, processed potato products, puddings, and various packaged meat and dairy alternatives to stabilize texture and retain moisture.

This ingredient is considered vegan because it is manufactured entirely from mineral and synthetic sources without the use of animal products or animal byproducts. The phosphate components originate from mined phosphate rock, and the neutralizing sodium compounds are derived from mineral salts. Because no animal-derived raw materials or processing aids are involved at any stage of its commercial production, foods containing E450iii are suitable for a vegan diet.
