Introduction to E470b Magnesium Salts of Fatty Acids

What is E470b?

E470b refers to magnesium salts of fatty acids, commonly known as magnesium stearate. It is a white, water-insoluble powder widely used in the food, pharmaceutical, and cosmetic industries due to its properties as an emulsifier, anti-caking agent, and stabilizer.

Production of E470b

Magnesium salts of fatty acids are produced by reacting magnesium oxide or magnesium hydroxide with stearic acid. The resulting compound is magnesium stearate, which is used in various applications to improve the texture, stability, and consistency of products.

Applications

1. Food Additive: E470b is used in the food industry to prevent ingredients from clumping together and to ensure even distribution in products like spices, baking mixes, and powdered foods.

2. Emulsifier: It helps in the formation and stabilization of emulsions, improving the texture and consistency of food products and cosmetics.

3. Anti-Caking Agent: Magnesium stearate prevents powdered and granulated ingredients from clumping together, ensuring smooth flow and easy processing.

4. Stabilizer: It enhances the stability of various products, preventing separation and maintaining uniformity.

5. Pharmaceutical Excipient: In the pharmaceutical industry, E470b is used as a lubricant in tablet manufacturing, ensuring smooth tablet compression and preventing ingredients from sticking to the equipment.

6. Food Grade: E470b is safe for consumption and is used in food products to improve their texture and consistency without affecting their nutritional value.

7. Lubricant: It is used as a lubricant in the production of capsules and tablets, aiding in the manufacturing process and ensuring high-quality finished products.

Health and Safety

Magnesium stearate is generally recognized as safe (GRAS) by the FDA and is approved for use in food and pharmaceutical products by various regulatory authorities. It is non-toxic, non-allergenic, and well-tolerated by most individuals.

Regulatory Status

E470b is approved for use in food, pharmaceutical, and cosmetic products worldwide. Manufacturers must comply with local regulations regarding its use and labeling to ensure transparency and consumer safety.

Environmental Impact

The production of magnesium stearate involves renewable resources, and efforts are made to minimize environmental impact during the manufacturing process. Sustainable practices are employed to ensure the responsible use of raw materials and reduce waste.
