Comparing E552 - Calcium silicate vs E560 - Potassium silicate

Overview

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.

E560 - Potassium silicate

Potassium silicate (E560) is a highly alkaline salt made from potassium and silica. In food, it is an uncommon additive used in specific, regulated applications, mainly to adjust or stabilize acidity and to help dry mixes handle moisture. On EU labels it may appear as “E560” or “potassium silicate.”

Popular questions

  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.

  1. What is potassium aluminum silicate?

    Potassium aluminium silicate is a different additive (E555), a naturally occurring aluminosilicate used mainly as an anti‑caking or glazing agent; it is not the same as E560. E560 is potassium silicate (K2SiO3), an inorganic silicate salt.

  2. What is the formula of potassium silicate?

    The common form is potassium metasilicate, K2SiO3. Commercial potassium silicate is often represented as K2O·nSiO2 (various ratios) and may be hydrated.

  3. : hydrated potassium sodium iron magnesium aluminum silicate is better known as what?

    Mica (e.g., muscovite/biotite), which is different from E560 potassium silicate.

  4. Canon e560 how to scan?

    That refers to a Canon printer model and is unrelated to the food additive E560; in food, E560 denotes potassium silicate (K2SiO3), an inorganic silicate salt.

  5. How di i gointo bios with a lenova thinkpad e560?

    That’s a laptop model unrelated to the food additive E560; here, E560 refers to potassium silicate (K2SiO3).
