Frequently Asked Questions
Q What is Magnesium Myristate and how is it different from Magnesium Stearate?
Magnesium Myristate (Magnesium Tetradecanoate) is a metallic soap derived from myristic acid (C14), while Magnesium Stearate is derived from stearic acid (C18). Magnesium Myristate offers a superior slip feel and better adhesion to skin, making it especially preferred in color cosmetics and high-performance powder formulations.
Q What is the recommended usage level of Magnesium Myristate in pressed powder formulations?
For pressed powders and eyeshadows, the recommended dosage is 2.0%~5.0%. For loose powders and face powders, a higher level of 5.0%~10.0% is typically used to achieve optimal binding and anti-caking performance.
Q Is Magnesium Myristate safe for use in cosmetics and pharmaceuticals?
Yes. Magnesium Myristate meets strict quality specifications including heavy metal limits (≤0.0020%), lead (≤0.0010%), and arsenic (≤0.0005%), making it suitable for both cosmetic and pharmaceutical-grade applications.
Q What are the key functional benefits of Magnesium Myristate in makeup products?
Magnesium Myristate provides a silky, slippery skin feel, strong adhesion to skin, excellent water resistance, and anti-caking properties. It also improves color payoff, spreadability, and long-wearing performance across a wide range of makeup products including foundations, eyeshadows, and mascaras.
Q Can Magnesium Myristate be used in industrial applications outside of cosmetics?
Yes. Beyond cosmetics, Magnesium Myristate is used as a lubricant and mold release agent in plastics and rubber processing, as a matting and abrasion-resistant agent in coatings and inks, and as a molding lubricant in metal powder metallurgy.
Q What are the storage and packaging requirements for Magnesium Myristate?
Magnesium Myristate is packaged in 20 kg bags and should be stored in a sealed container in a cool, dry warehouse. Proper storage conditions help maintain its quality, prevent moisture absorption, and preserve its physical properties over time.
