Comparing E546 - Magnesium pyrophosphate vs E552 - Calcium silicate

Overview

E546 - Magnesium pyrophosphate

Magnesium pyrophosphate (E546) is a phosphate-based mineral salt used in small amounts to help foods keep the right texture, especially dry mixes. It belongs to the family of phosphate additives and is typically used for processing performance rather than flavor or nutrition.

E552 - Calcium silicate

Calcium silicate (E552) is a mineral-based food additive used mainly as an anti-caking agent. It soaks up moisture and keeps powders free-flowing in products like table salt and spice blends. It is permitted in the U.S. and EU within set purity and use rules.

Popular questions

  1. How to removelifebook e546 keyboard?

    That looks like a question about a Fujitsu LifeBook E546 laptop and isn’t related to the food additive E546; in foods, E546 refers to magnesium pyrophosphate, an inorganic salt used mainly as an anti-caking or stabilizing agent.

  2. What is sodium magnesium silicate & tetrasodium pyrophosphate?

    They are different inorganic food additives: sodium magnesium silicate is a mineral-based anti-caking/thickening agent that helps powders stay free‑flowing, while tetrasodium pyrophosphate (a phosphate) is a sequestrant/buffer used to improve texture and water binding; both are distinct from E546 (magnesium pyrophosphate).

  1. How to remove calcium silicate from pool?

    Calcium silicate scale is very hard and relatively acid‑resistant, so it’s typically removed by mechanical means (pumice/scale pads or bead blasting) after lowering pH and using a sequestering agent; an acid spot test that doesn’t fizz helps confirm it’s silicate, not carbonate. Prevent recurrence by keeping water balanced (pH/alkalinity/calcium) and using a sequestrant.

  2. What is calcium silicate board?

    A rigid, noncombustible building/insulation board made from calcium silicate hydrates, valued for fire resistance, moisture tolerance, and dimensional stability. It’s used for fireproofing, lining stoves/flues, and thermal or acoustic insulation.

  3. How to cut calcium silicate board?

    Score‑and‑snap works for thin sheets; thicker boards are cut with a circular saw using a carbide or diamond blade at a slow feed rate. Control dust with wet cutting or HEPA extraction and wear PPE (respirator, eye protection, gloves).

  4. Is calcium silicate bad for you?

    As a food additive (E552) used mainly as an anticaking agent, it’s considered safe at permitted levels (JECFA ADI “not specified”; FDA GRAS). The main concern is inhaling fine dust in occupational settings, which can irritate the respiratory tract.

  5. Is calcium silicate vegan?

    Yes—it's a mineral/synthetic ingredient with no animal-derived components, so E552 is generally suitable for vegans.
