biolla chemicals supplies magnesium stearate (CAS 557-04-0, E470b) in USP / BP / EP quality. Our magnesium stearate is vegan and palm oil-free, a key requirement for many food supplement and clean-label brands. We supply pharmaceutical, food supplement, food and cosmetics manufacturers across Europe.
Magnesium stearate is the magnesium salt of fatty acids, mainly stearic and palmitic acid. These fatty acids can come from animal fats, palm oil or other vegetable oils. Our magnesium stearate is of vegetable origin and not derived from palm oil.
Please tell us which documents you need for your vegan or palm oil-free claims, and we will send them together with the specification, CoA and SDS.
Magnesium stearate is usually added at low levels to the final blend, often together with microcrystalline cellulose MCC 101 / 102 as filler and binder.

Magnesium Stearate is widely used in the pharmaceutical industry as a lubricant and anti-adherent in tablet and capsule formulations. In the food industry, it serves as an anti-caking agent and emulsifier. In cosmetics, it improves texture and stability, providing a silky feel in powders and creams.
Magnesium Stearate should be stored in a cool, dry place, away from moisture and direct sunlight. Ensure the storage area is well-ventilated and free from sources of ignition. The product should be kept in tightly sealed containers to prevent contamination and maintain its quality. Avoid storing near incompatible materials such as strong acids and oxidizing agents. Proper storage conditions will ensure the stability and effectiveness of Magnesium Stearate.
