Magnesiumstearaat

Magnesiumstearaat is a salt of magnesium and stearic acid, a saturated fatty acid. It typically appears as a white, powdery substance. Its primary use is as an anti-caking agent, preventing powdered substances from clumping together. This property makes it a common additive in various industries, including pharmaceuticals, food manufacturing, and cosmetics.

In the pharmaceutical industry, magnesiumstearaat serves as a lubricant in the production of tablets and capsules. It helps to prevent the ingredients from sticking to the manufacturing equipment, ensuring smooth and consistent production. It is also used to improve the flow of powders, which is essential for accurate dosing.

In the food industry, it is often found in dietary supplements, processed foods, and confectionery as an anti-caking agent and emulsifier. It helps to maintain the texture and consistency of these products. In cosmetics, it contributes to the texture and spreadability of products like powders, blushes, and foundations.

Magnesiumstearaat is generally recognized as safe (GRAS) by regulatory bodies when used within specified limits. While it is a common ingredient, some individuals may express concerns about its potential effects. However, scientific studies have largely found it to be safe for consumption and topical application. Its production involves reacting magnesium oxide or hydroxide with stearic acid.
