Quaternium-85, also known by its chemical name Propanaminium, 2-hydroxy-3-((2-hydroxyethyl)(2-(1-oxotetradecylamino)ethyl)amino)-N,N,N-trimethyl-, chloride, is a versatile ingredient commonly found in a variety of hair care products. This ingredient is primarily sourced from the chemical modification of fatty acids, often derived from natural oils such as coconut or palm oil. In the cosmetics industry, it is also sometimes referred to as a quaternary ammonium compound or simply a “quat.”
The history of Quaternium-85 in cosmetics dates back to the mid-20th century when chemists were exploring new ways to improve the conditioning properties of hair care products. The discovery of quaternary ammonium compounds revolutionized the industry by providing superior antistatic and conditioning benefits compared to earlier formulations. Over the years, Quaternium-85 has become a staple in many shampoos, conditioners, and styling products due to its effectiveness and relatively low cost.
The production of Quaternium-85 involves a series of chemical reactions starting with the esterification of fatty acids, followed by a quaternization process. This process typically includes the reaction of fatty acids with amines and subsequent treatment with methyl chloride to form the final quaternary ammonium compound. The result is a highly stable and water-soluble ingredient that can easily be incorporated into various cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Quaternium-85:
One of the primary benefits of Quaternium-85 is its antistatic properties. In simple terms, this means it helps to reduce or eliminate static electricity in your hair. If you’ve ever experienced the frustration of flyaway hairs or hair that sticks to your clothes, Quaternium-85 can be a game-changer. By neutralizing the electrical charges that cause static, it helps keep your hair smooth and manageable, making it easier to style and maintain throughout the day.
Quaternium-85 is also recognized for its hair conditioning capabilities. This ingredient works by coating the hair shaft, which helps to lock in moisture and make your hair feel softer and look shinier. It’s particularly beneficial for those with dry or damaged hair, as it can help to restore some of the lost moisture and improve the overall texture and appearance of your hair. Additionally, conditioned hair is less prone to tangling and breakage, making it easier to comb and style.
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-85 is generally considered safe for use in cosmetic products, but like any ingredient, it may not be suitable for everyone. 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-85 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-85 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-85 has a comedogenic rating of 1, which means it is considered to be minimally comedogenic. This low rating suggests that it is unlikely to clog pores or cause breakouts, making it generally suitable for individuals prone to acne or blemishes. However, individual reactions can vary, so monitoring your skin’s response is always a good practice.
