Quaternium-82, also known by its chemical name [2-[bis(2-Hydroxypropyl)amino]ethyl]bis(2-hydroxypropyl)(methyl)ammonium methyl sulphate, dioleate (ester), is a synthetic ingredient commonly used in cosmetic products. This compound is primarily sourced from a combination of chemical reactions involving various alcohols and fatty acids, resulting in a quaternary ammonium compound. It is often referred to simply as Quaternium-82 in ingredient lists.
The history of Quaternium-82 in cosmetics dates back to the mid-20th century when the demand for more effective hair conditioning and antistatic agents began to rise. Scientists and cosmetic chemists were on the lookout for ingredients that could provide superior conditioning benefits without weighing down the hair or causing buildup. Quaternium-82 emerged as a solution due to its unique chemical structure, which allows it to bond effectively with hair fibers, providing long-lasting conditioning effects.
The production of Quaternium-82 involves a series of chemical reactions. Initially, fatty acids are esterified with alcohols to form esters. These esters are then reacted with a quaternary ammonium compound, resulting in the formation of Quaternium-82. The process is carefully controlled to ensure the purity and efficacy of the final product, making it suitable for use in various hair care formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Quaternium-82:
One of the primary benefits of Quaternium-82 is its antistatic property. This means that it helps to reduce or eliminate static electricity in hair. If you’ve ever experienced frizzy hair that stands on end, especially in dry or cold weather, you know how annoying static can be. Quaternium-82 works by neutralizing the electrical charges on the hair’s surface, making your hair smoother and more manageable. This is particularly beneficial for those who frequently use hair styling tools like blow dryers and straighteners, which can exacerbate static issues.
Quaternium-82 also serves as a hair conditioning agent. This means it helps to improve the texture and appearance of your hair, making it softer, shinier, and easier to comb through. It works by forming a thin, protective layer on the hair shaft, which helps to lock in moisture and prevent damage from environmental factors like UV rays and pollution. This conditioning effect can be particularly beneficial for those with dry, damaged, or chemically treated hair, as it helps to restore a healthy look and feel.
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-82 is generally considered safe for use in cosmetic products, with its primary functions being antistatic and hair conditioning. 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 Quaternium-82 during pregnancy are lacking. Therefore, it is advisable to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Quaternium-82 are generally uncommon. However, it is recommended to perform a patch test before widespread usage to ensure that you do not have a sensitivity to the ingredient.
Quaternium-82 has a comedogenic rating of 1, which means it is considered to be low on the scale of pore-clogging potential. This makes it relatively safe for individuals who are prone to acne, blemishes, or breakouts, as it is unlikely to contribute to these skin issues.
