Magnesium Laureth-16 Sulfate, scientifically known as Poly(oxy-1,2-ethanediyl), .alpha.-hydro-.omega.-dodecyloxy-, sulfates, magnesium salts (16 mol EO average molar ratio), is a synthetic compound primarily used in cosmetic products for its cleansing properties. This ingredient is derived from lauryl alcohol, which is typically sourced from coconut oil or palm kernel oil. The “16” in its name refers to the average number of ethylene oxide units in its structure, which contributes to its ability to mix with both water and oils, making it an effective surfactant.
The use of Magnesium Laureth-16 Sulfate in cosmetics has a relatively recent history, emerging as a response to the growing demand for more efficient and versatile cleansing agents. Initially, simpler sulfates like Sodium Lauryl Sulfate were widely used, but they were often criticized for being too harsh on the skin. This led to the development of more sophisticated compounds like Magnesium Laureth-16 Sulfate, which offer a milder yet effective cleansing action.
The production of Magnesium Laureth-16 Sulfate involves a multi-step chemical process. First, lauryl alcohol undergoes ethoxylation, where ethylene oxide is added to create a series of ethoxylated alcohols. This mixture is then sulfated, introducing sulfate groups into the compound. Finally, the sulfated mixture is neutralized with magnesium salts to produce the final ingredient. This meticulous process ensures that the compound is both effective and safe for use in a variety of cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Magnesium Laureth-16 Sulfate:
Magnesium Laureth-16 Sulfate is primarily known for its cleansing properties. This means it helps to remove dirt, oil, and other impurities from the skin and hair. When used in products like shampoos, body washes, and facial cleansers, it works by creating a lather that lifts away grime and debris, leaving your skin and hair feeling fresh and clean. This ingredient is particularly effective in breaking down and emulsifying oils, making it easier to wash them away with water.
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-16 Sulfate is generally considered safe for use in cosmetic products. However, like any ingredient, it may cause side effects in some individuals. The potential side effects of topical application of this ingredient include:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Magnesium Laureth-16 Sulfate during pregnancy are lacking. Therefore, it is recommended that pregnant or breastfeeding women consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Magnesium Laureth-16 Sulfate are relatively uncommon, but they can occur. To minimize the risk of an adverse reaction, it is advisable to perform a patch test before widespread usage of any new product containing this ingredient.
Magnesium Laureth-16 Sulfate has a comedogenic rating of 1, which means it is considered to be minimally comedogenic. This low rating indicates that it is unlikely to clog pores and cause acne or breakouts, making it generally suitable for individuals prone to blemishes. However, individual reactions can vary, and it is important to monitor your skin’s response when using any new cosmetic product.
