Mustakshif Shariah Board Rulings on E470B (Magnesium Salts of Fatty Acids)

According to Mustakshif Shariah Board,E470B (Magnesium Salts of Fatty Acids) is classified as Mushbooh (not Halal) This is due to uncertainty surrounding its source. While the magnesium part comes from natural minerals, the fatty acids may originate from either plant oils or animal fats. If sourced from tallow, the halal status depends on the animal's origin and whether it was slaughtered according to Islamic law. Without this information, the permissibility of the ingredient remains unclear.

Is it permissible? Here’s what the fatwas say

At present, there are no specific fatwas clearly addressing E470b. The halal acceptability is left to the verification of its source. Many Islamic authorities recommend checking with manufacturers or selecting products that confirm plant-based origins.

The basics of magnesium salts of fatty acids

E470B, officially known as Magnesium Salts of Fatty Acids, is a multi-functional food additive. It is classified under the E-number system as E470b. The ingredient also appears under various names, including Magnesium Stearate, Magnesium Octadecanoate, and Magnesium Salts of Stearic and Palmitic Acids.

How is E740 B obtained?

This ingredient is created through a reaction involving fatty acids and magnesium compounds. The fatty acids are obtained by breaking down animal fats or plant oils like palm or coconut through saponification. During this process, fats are treated with a strong base to isolate the fatty acids. These acids are then combined with magnesium hydroxide or magnesium oxide to form magnesium salts. A final purification step ensures the compound meets quality standards.

Common uses of E470b

In food products, E470b acts as an anti-caking agent, helping powders stay loose and free-flowing. You can also use it as an emulsifier to mix more effectively. Additionally, it also prevents food and supplements from sticking to molds or packaging. Beyond food, it’s used in pharmaceuticals to assist in tablet production and in cosmetics to improve product texture and shelf stability.

Closing remarks

E470b (Magnesium Salts of Fatty Acids) is a versatile additive with widespread industrial use. It helps with mixing, preventing clumps, and improving product handling. However, due to the dual nature of its sources, it is best treated as doubtful unless verified, particularly for consumers following halal dietary rules.
