Magnesium Oleth Sulfate, known chemically as Poly(oxy-1,2-ethanediyl), .alpha.-sulfo-.omega.-(9-(Z)-octadecenyl)oxy-, magnesium salts (2:1) (1-4 mol EO average molar ratio), is a synthetic ingredient primarily used in cosmetic products for its cleansing properties. This compound is derived from the reaction of ethylene oxide with oleyl alcohol, followed by sulfation and neutralization with magnesium salts. The result is a surfactant that effectively helps to remove dirt, oil, and impurities from the skin and hair.
The use of Magnesium Oleth Sulfate in cosmetics has evolved over the years. Initially, the focus was on finding effective and mild surfactants that could replace harsher cleansing agents. As the cosmetic industry advanced, the need for ingredients that could provide a gentle yet effective cleansing experience became paramount. Magnesium Oleth Sulfate emerged as a suitable candidate due to its ability to create a rich lather while being less irritating to the skin compared to traditional sulfates.
The manufacturing process of Magnesium Oleth Sulfate involves several steps. First, oleyl alcohol is ethoxylated by reacting it with ethylene oxide, resulting in a series of ethoxylated alcohols. These alcohols are then sulfated, typically using sulfur trioxide or chlorosulfonic acid, to introduce the sulfate group. Finally, the sulfated product is neutralized with magnesium salts to produce the final compound. This multi-step process ensures that the ingredient is both effective and safe for use in various cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Magnesium Oleth Sulfate:
Magnesium Oleth Sulfate is primarily used for its cleansing properties. This means it helps to remove dirt, oil, and other impurities from the skin and hair. When included in cosmetic products like shampoos, body washes, and facial cleansers, it works by breaking down and emulsifying oils and grime, making it easier to wash 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 Oleth Sulfate is generally considered safe for use in cosmetic products. However, as with any ingredient, there are potential side effects and considerations to keep in mind.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Magnesium Oleth 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 Oleth Sulfate are generally 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.
Magnesium Oleth Sulfate has a comedogenic rating of 2, which means it has a low to moderate likelihood of clogging pores. Individuals who are prone to acne, blemishes, or breakouts should be cautious when using products containing this ingredient, as it may contribute to pore congestion in some cases.
