Magnesium Laureth-5 Sulfate is a synthetic ingredient commonly used in cosmetic products for its cleansing properties. Chemically, it is known as Poly(oxy-1,2-ethanediyl), .alpha.-hydro-.omega.-dodecyloxy-, sulfates, magnesium salts (5 mol EO average molar ratio). This rather complex name indicates that the molecule is a magnesium salt of sulfated ethoxylated lauryl alcohol, with an average of five ethylene oxide units per molecule.
The history of Magnesium Laureth-5 Sulfate in cosmetics dates back to the mid-20th century when the demand for effective and mild surfactants began to rise. Surfactants are compounds that lower the surface tension between two substances, such as a solid and a liquid, or a liquid and a gas. This ingredient was developed as part of a broader effort to create more efficient and skin-friendly cleansing agents. Over time, it has become a staple in various personal care products, including shampoos, body washes, and facial cleansers.
The production of Magnesium Laureth-5 Sulfate involves several steps. First, lauryl alcohol is ethoxylated by reacting it with ethylene oxide, resulting in lauryl alcohol ethoxylate. This intermediate product is then sulfated, typically using sulfur trioxide or chlorosulfonic acid, to introduce the sulfate group. Finally, the sulfated product is neutralized with magnesium hydroxide or magnesium oxide to form the magnesium salt. This multi-step synthesis ensures that the final product is both effective and safe for use in cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Magnesium Laureth-5 Sulfate:
Magnesium Laureth-5 Sulfate is primarily known for its cleansing properties. This means it helps to remove dirt, oil, and impurities from the skin and hair. When used in products like shampoos, body washes, and facial cleansers, it creates a lather that effectively lifts away grime, leaving you feeling fresh and clean. This is particularly beneficial for those who are exposed to pollutants or have oily skin, as it helps to maintain a clean and clear complexion.
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 Laureth-5 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 its topical application:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Magnesium Laureth-5 Sulfate during pregnancy are lacking. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.
Side effects and adverse reactions from Magnesium Laureth-5 Sulfate are relatively uncommon. However, it is always recommended to perform a patch test before widespread usage to ensure that the ingredient does not cause any adverse reactions on your skin.
Magnesium Laureth-5 Sulfate has a comedogenic rating of 1, which means it is very unlikely to clog pores. This makes it a suitable option for individuals who are prone to acne, blemishes, or breakouts.
