Popular questions
Is phosphoric acid bad for you?
At permitted food levels it’s considered safe (GRAS in the U.S.; EFSA sets a group ADI for phosphates of 40 mg/kg bw/day as phosphorus). Overconsumption—especially via acidic soft drinks—can contribute to dental enamel erosion, and high phosphate intakes may be a concern for people with kidney disease.
Is phosphoric acid a strong acid?
No—it's a weak, triprotic acid (pKa ≈ 2.15, 7.2, 12.3), though concentrated solutions are corrosive.
What is phosphoric acid used for?
In foods it’s used as an acidulant to add tartness and control pH (e.g., in colas) and as a sequestrant/antioxidant to stabilize color and flavor.
What does phosphoric acid do to the body?
It dissociates into phosphate ions, which are essential for bones and energy metabolism, while the acid load is buffered and excreted. High intakes from acidic drinks can erode tooth enamel, and excess phosphate may be problematic in kidney disease or with low calcium intake.
What is the formula for phosphoric acid?
H3PO4.
What is calcium disodium edta?
Calcium disodium EDTA (E385) is a synthetic chelating agent—closely related to disodium EDTA (E386)—that binds trace metals in foods to help prevent off-flavors, discoloration, and oxidation.
Is calcium disodium edta harmful?
Not at permitted food-use levels; regulators set an acceptable daily intake of roughly 1.9–2.5 mg/kg body weight/day, and typical intakes are well below this. Very high doses can chelate essential minerals and may cause stomach upset.
Is disodium edta safe for skin?
Yes—disodium EDTA is widely used in cosmetics at low levels and is considered safe, with a low risk of irritation for most people.
Is calcium disodium edta bad for you?
No—when used within legal limits in foods, it’s considered safe; concerns mainly arise only at excessive exposures that could deplete minerals.
Is disodium edta safe?
Yes—within approved uses and limits, disodium EDTA is considered safe; EDTA salts have an ADI of about 1.9–2.5 mg/kg body weight/day set by major regulators.
