Quaternium-71, also known by its chemical name (Z,Z)-(dimethyl)[3-[(1-oxo-9,12-octadecadienyl)amino]propyl][2-oxo-2-(tetradecyloxy)ethyl]ammonium chloride, is a synthetic compound primarily used in cosmetic products for its antistatic properties. This ingredient is part of the quaternary ammonium compounds family, which are well-known for their ability to neutralize static electricity and improve the texture and manageability of hair.
The history of Quaternium-71 in cosmetics dates back to the mid-20th century when chemists began exploring quaternary ammonium compounds for their conditioning and antistatic benefits. Over time, these compounds have been refined and tailored to meet the specific needs of various cosmetic formulations, leading to the development of Quaternium-71.
Quaternium-71 is synthesized through a series of chemical reactions that involve the combination of fatty acids, amines, and alkylating agents. The process begins with the derivation of fatty acids from natural sources such as vegetable oils. These fatty acids are then reacted with amines to form amides, which are subsequently quaternized with alkylating agents to produce the final quaternary ammonium compound. The result is a stable, water-soluble ingredient that can be easily incorporated into a wide range of cosmetic products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Quaternium-71:
One of the primary benefits of Quaternium-71 is its antistatic properties. This means that it helps to reduce or eliminate the buildup of static electricity. In a cosmetic context, this is particularly useful for hair care products. Static electricity can cause hair to become frizzy, flyaway, and difficult to manage. By incorporating Quaternium-71 into shampoos, conditioners, and styling products, manufacturers can help keep hair smooth, manageable, and free from static cling.
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-71 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 of this ingredient:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Quaternium-71 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-71 are relatively uncommon, but they can occur. To minimize the risk of an adverse reaction, it is recommended to conduct a patch test before widespread usage.
In terms of comedogenicity, Quaternium-71 is rated as a 1 on a scale of 0 (totally non-comedogenic) to 5 (highly comedogenic). This means it is unlikely to clog pores and is generally suitable for people prone to acne, blemishes, or breakouts. However, individual reactions can vary, so monitoring your skin’s response is always a good practice.
