Overview

E470A - Sodium/potassium and calcium salts of fatty acids

Sodium/potassium and calcium salts of fatty acids (E470a) are food-grade “soap-like” compounds made by combining common fatty acids with minerals. They help oil and water mix, keep powders free‑flowing, and stop foods from sticking to equipment. Regulators in the U.S. and EU allow their use within good manufacturing practice.

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.
