Overview

E470B - Magnesium salts of fatty acids

Magnesium salts of fatty acids (E470B) are common processing aids used in very small amounts. They help powders flow, keep mixes from clumping, and act as mild emulsifiers and release agents. You’ll often see the name magnesium stearate, which is one specific magnesium salt of a fatty acid.

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.

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