Quaternium-18 Methosulfate, also known as bis(hydrogenated tallow alkyl)dimethyl, Me sulfates, is a quaternary ammonium compound commonly used in the cosmetic industry. This ingredient is primarily derived from hydrogenated tallow, which is a form of processed animal fat, although synthetic versions can also be produced. Its chemical composition includes two long alkyl chains attached to a nitrogen atom, which is further bonded to a methyl group and a sulfate group.
The use of quaternary ammonium compounds in cosmetics dates back several decades. Initially, these compounds were introduced for their superior conditioning properties, particularly in hair care products. Over time, Quaternium-18 Methosulfate became a popular choice due to its effectiveness in reducing static electricity and improving the manageability of hair.
The production of Quaternium-18 Methosulfate involves a chemical reaction between hydrogenated tallow and dimethyl sulfate. This process results in the formation of a quaternary ammonium salt, which is then purified and formulated for use in various cosmetic products. The ingredient is valued for its ability to provide a smooth, silky feel to hair and skin, making it a staple in many conditioners, shampoos, and lotions.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Quaternium-18 Methosulfate:
One of the primary benefits of Quaternium-18 Methosulfate is its antistatic properties. This means that it helps to reduce static electricity in hair, which can be a common problem, especially in dry or windy conditions. By minimizing static, this ingredient helps to keep hair smooth and manageable, preventing the frizz and flyaways that can make styling difficult. Essentially, it makes your hair easier to comb and style, giving it a sleeker, more polished appearance.
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).
Quaternium-18 Methosulfate is generally considered safe for use in cosmetic products, but 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 Quaternium-18 Methosulfate 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.
Adverse reactions to Quaternium-18 Methosulfate are relatively uncommon, but they can occur. To minimize the risk of irritation or allergic reactions, it is recommended to perform a patch test before widespread usage.
Quaternium-18 Methosulfate has a comedogenic rating of 1, meaning it is very unlikely to clog pores. This makes it a suitable option for individuals prone to acne, blemishes, or breakouts, as it is unlikely to exacerbate these conditions.
