| E338 | Phosphoric acid | food acid, derived from phosphate ore; used in cheese products;no known adverse effects | |
| E339 | Sodium phosphates | mineral salt, used as a laxative and a fixing agent in textile dyeing; high intakes may upset the calcium/phosphorus equilibrium | |
| E340 | Potassium phosphates | see 339 | |
| E341# | Calcium phosphates | mineral salt found in rocks and bones; used in medicines as an antacid and polishing agent in enamels | |
| E343 | Magnesium phosphates | essential mineral, anticaking agent found in salt substitutes | |
