- Magnesium stearate, also called octadecanoic acid or magnesium salt, is a white substance, powder which becomes solid at room temperature.
- Magnesium stearate is a compound of magnesium salt and stearic acid, which is a saturated fat found in many foods, says WorldwideHealth.com. It is often used in dietary supplements and cosmetic products and is generally considered to be safe.
- Magnesium stearate is used in dietary supplements because your body can easily convert it into monounsaturated fat–of the kind found in olive oil—and it does not raise levels of harmful cholesterol in your bloodstream, says WorldwideHealth.com.
- It is also a natural lubricant that prevents other ingredients in a supplement from clumping together.
- Blended Cosmetics: The anti-coagulating properties in magnesium stearate also make it a common ingredient in cosmetics as it helps products such as foundation, lip gloss and mascara from separating into liquid and oil, says CosmeticsInfo.org. It is also used in perfumes, deodorants and hair care products. The Cosmetic Ingredient Review Expert Panel has deemed magnesium stearate safe to use in cosmetics and fragrances.
- Some skin types may have a sensitivity to it, so be aware of any adverse symptoms, such as rash, redness or itchiness, that appear when wearing or using products containing this ingredient.
- While magnesium stearate delivers a number of benefits, it is important to use this product with caution–especially if you are taking other medication or prone to allergies–and check with your doctor that it is safe for you to use.
