Quaternium-77, also known by its chemical name 1-Propanaminium, 2-hydroxy-N-ethyl-N,N-bis(2-aminoethyl)-, N’,N”-bis(mixed octadecanoyl and hexadecanoyl) derivs., ethyl sulfates (salts) (1:1), is a versatile ingredient commonly found in hair care products. This compound is part of the quaternary ammonium compounds family, which are known for their conditioning and antistatic properties. In the cosmetics industry, Quaternium-77 is prized for its ability to improve the texture and manageability of hair.
The history of Quaternium-77 in cosmetics dates back to the mid-20th century when chemists began exploring quaternary ammonium compounds for their potential benefits in personal care products. These compounds were found to be particularly effective in reducing static electricity and enhancing the softness and smoothness of hair. Over time, Quaternium-77 emerged as a popular choice due to its superior performance and compatibility with a wide range of formulations.
Quaternium-77 is synthesized through a series of chemical reactions involving the combination of fatty acids (such as octadecanoyl and hexadecanoyl) with ethyl sulfate and other amine derivatives. This process results in a compound that can easily bond with hair fibers, providing long-lasting conditioning effects. The manufacturing process is carefully controlled to ensure the purity and efficacy of the final product, making it a reliable ingredient in many hair care formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Quaternium-77:
One of the primary benefits of Quaternium-77 is its antistatic property. This means it helps to reduce or eliminate static electricity, which can be a common problem, especially in dry or cold climates. Static electricity can cause hair to become frizzy, flyaway, and difficult to manage. By incorporating Quaternium-77 into hair care products, manufacturers can help users achieve smoother, more manageable hair that is less prone to static-induced frizz and flyaways.
Quaternium-77 is also recognized for its hair conditioning capabilities. This ingredient helps to improve the texture and appearance of hair by making it softer, shinier, and easier to comb. It works by coating the hair shaft, which can help to smooth the cuticle and reduce tangling. 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-77 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 other considerations.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Quaternium-77 during pregnancy and breastfeeding 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.
Side effects and adverse reactions from Quaternium-77 are relatively uncommon, but they can occur. It is recommended to perform a patch test before widespread usage to ensure that the product is suitable for your skin.
Quaternium-77 has a comedogenicity rating of 1, which means it is very unlikely to clog pores. This makes it a suitable option for individuals who are prone to acne, blemishes, or breakouts.
