Magnesium Myristate is a fine white powder derived from the salt of myristic acid and magnesium. Myristic acid is a naturally occurring fatty acid found in nutmeg, palm oil, coconut oil, and butter fat. When combined with magnesium, it forms Magnesium Myristate, which is primarily used in the cosmetic industry for its unique properties.
The history of Magnesium Myristate in cosmetics dates back several decades. Initially, it was discovered for its ability to improve the texture and application of various cosmetic products. Over time, its use has expanded as formulators recognized its multifunctional benefits, including its role as an anticaking agent, opacifying agent, and viscosity controlling agent.
The production of Magnesium Myristate involves a chemical reaction between myristic acid and a magnesium compound, typically magnesium oxide or magnesium hydroxide. This reaction results in the formation of a stable, non-toxic compound that can be easily incorporated into a wide range of cosmetic formulations. The process ensures that the final product is safe for use on the skin and effective in enhancing the performance of cosmetics.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Magnesium Myristate:
Magnesium Myristate acts as an anticaking agent, which means it helps prevent the clumping of powdered or granular products. This is particularly beneficial in cosmetics like face powders, eyeshadows, and blushes, ensuring they remain smooth and easy to apply. By keeping the product free-flowing, it enhances the overall user experience and maintains the product’s quality over time.
As an opacifying agent, Magnesium Myristate is used to make products less transparent or opaque. This is useful in formulations where a more solid, non-transparent appearance is desired, such as in foundations, concealers, and certain skincare products. It helps in providing better coverage and a more uniform appearance on the skin, making imperfections less visible.
Magnesium Myristate also serves as a viscosity controlling agent, meaning it helps to adjust the thickness or thinness of a cosmetic product. This is crucial for achieving the desired consistency in creams, lotions, and gels. By controlling viscosity, it ensures that the product spreads evenly and feels pleasant on the skin, enhancing the overall application experience.
Note: The listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
Magnesium Myristate is generally considered safe for use in cosmetic products. However, like any ingredient, it may cause side effects in some individuals. Here are some potential side effects of topical application:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Magnesium Myristate during pregnancy and breastfeeding are lacking. Therefore, it is advisable to consult a healthcare professional for further advice.
Adverse reactions to Magnesium Myristate are generally uncommon. However, it is recommended to perform a patch test before widespread usage to ensure there are no adverse reactions.
Magnesium Myristate has a comedogenicity rating of 2, which means it has a low to moderate likelihood of clogging pores. For individuals prone to acne, blemishes, or breakouts, this means that while the risk is not high, it is still present, and they should monitor their skin’s reaction to products containing this ingredient.
