Quaternium-75, also known by its more technical name, Quaternary ammonium compounds, ethyl(2-hydroxy-C14-16-alkyl)bis[3-(ethyldimethylammonio)propyl]-, ethyl sulfates (salts) (1:3), is a synthetic compound primarily used in cosmetic products for its antistatic and hair conditioning 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-75 in cosmetics dates back to the mid-20th century when chemists began exploring the potential of quaternary ammonium compounds in personal care products. These compounds were found to be highly effective in reducing static and conditioning hair, leading to their widespread adoption in shampoos, conditioners, and other hair care formulations.
Quaternium-75 is synthesized through a chemical process that involves the reaction of fatty alcohols (derived from natural sources like coconut or palm oil) with ethylene oxide and dimethyl sulfate. This reaction produces a compound that is both hydrophilic (water-attracting) and lipophilic (oil-attracting), making it an excellent conditioning agent that can adhere to hair strands and provide lasting benefits.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Quaternium-75:
One of the primary benefits of Quaternium-75 is its antistatic properties. This means it helps to reduce or eliminate static electricity in your hair. If you’ve ever experienced flyaway hairs or that annoying static cling, Quaternium-75 can be a lifesaver. 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-75 is also recognized for its hair conditioning capabilities. This ingredient works by coating the hair shaft, which helps to smooth the cuticle and improve the overall texture of your hair. The result is softer, shinier, and more hydrated locks. This conditioning effect can be particularly beneficial for those with dry or damaged hair, as it helps to restore moisture and improve the hair’s appearance 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-75 is generally considered safe for use in cosmetic products, but as with any ingredient, it is important to be aware of its potential side effects and suitability for different individuals.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Quaternium-75 during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Quaternium-75 are relatively uncommon, but they can occur. It is recommended to perform a patch test before widespread usage to ensure that you do not have an adverse reaction to the ingredient.
Quaternium-75 has a comedogenicity rating of 1, which means it is considered to be low on the scale of pore-clogging potential. This makes it a suitable option for individuals who are prone to acne, blemishes, or breakouts, as it is unlikely to contribute to these skin issues.
