Magnesium Myreth Sulfate is a synthetic ingredient primarily used in cosmetic and personal care products for its cleansing properties. Chemically, it is known as Poly(oxy-1,2-ethanediyl), .alpha.-sulfo-.omega.-tetradecyloxy-, magnesium salts (2:1) (1-4 mol EO average molar ratio). This rather complex name breaks down to a compound that includes ethylene oxide units and a sulfate group, combined with magnesium salts. The ingredient is derived from fatty alcohols, typically sourced from coconut or palm kernel oil, which undergo a series of chemical reactions to produce the final compound.
The use of Magnesium Myreth Sulfate in cosmetics dates back several decades. It emerged as a popular alternative to harsher sulfates like Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES), which are known for their strong cleansing abilities but can also be irritating to the skin. As consumers began to seek gentler yet effective cleansing agents, Magnesium Myreth Sulfate gained traction for its milder profile.
The production process of Magnesium Myreth Sulfate involves ethoxylation, where ethylene oxide is added to fatty alcohols to create ethoxylated alcohols. These are then sulfated, introducing the sulfate group, and finally neutralized with magnesium salts to form the end product. This multi-step process ensures that the ingredient maintains its cleansing efficacy while being less irritating compared to traditional sulfates.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Magnesium Myreth Sulfate:
Magnesium Myreth Sulfate is primarily used for its cleansing properties. This means that it helps to remove dirt, oil, and other impurities from the skin and hair. When included in products like shampoos, body washes, and facial cleansers, it works by breaking down and emulsifying oils and grime, making it easier to rinse them away. This leaves your skin and hair feeling clean and refreshed.
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 Myreth Sulfate is generally considered safe for use in cosmetic products, but like any ingredient, it may cause adverse reactions 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 Myreth Sulfate during pregnancy are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice.
Adverse reactions to Magnesium Myreth Sulfate are relatively uncommon, but they can occur. It is recommended to perform a patch test before widespread usage to ensure that the ingredient does not cause any adverse reactions.
Magnesium Myreth Sulfate has a comedogenic rating of 1, meaning it is unlikely to clog pores. This makes it a suitable option for individuals who are prone to acne, blemishes, or breakouts.
