Is monobasic sodium phosphate vegan?

Monobasic sodium phosphate, also known as monosodium phosphate or sodium dihydrogen phosphate, is an inorganic chemical compound consisting of sodium and phosphate ions. It is produced synthetically by neutralizing phosphoric acid, which is derived from mined phosphate rock, with sodium carbonate or sodium hydroxide. In the food industry, it serves as an emulsifier, pH buffer, leavening acid, and moisture-retention agent. It commonly appears on ingredient labels for processed cheeses, evaporated milk, powdered drink mixes, baked goods, and breakfast cereals.

This ingredient is classified as vegan because it is derived exclusively from mineral and synthetic origins with no animal involvement. The phosphorus originates from naturally occurring mineral ores, and the sodium components are processed from non-animal mineral salts. No animal tissues, animal derivatives, or animal-based processing aids are utilized at any stage of its chemical synthesis. Because it contains no animal products and requires no animal inputs to manufacture, monobasic sodium phosphate is suitable for a vegan diet.
