Quaternium-18/Benzalkonium Bentonite is a unique blend of quaternary ammonium compounds, bis(hydrogenated tallow alkyl)dimethyl, combined with bentonite and C8-C18-alkylbenzyldimethylammonium chloride. This ingredient is primarily sourced from a combination of natural clay (bentonite) and synthetic quaternary ammonium compounds. The bentonite component is a type of absorbent clay that has been used for centuries in various applications, while the quaternary ammonium compounds are known for their conditioning and antimicrobial properties.
The history of Quaternium-18/Benzalkonium Bentonite in cosmetics is relatively recent, emerging as a multifunctional ingredient that enhances the texture and stability of products. Initially, bentonite was used in skincare for its ability to absorb excess oil and impurities. However, combining it with quaternary ammonium compounds has expanded its utility, making it a popular choice for modern formulations that require viscosity control and improved product consistency.
The manufacturing process of Quaternium-18/Benzalkonium Bentonite involves the careful blending of hydrogenated tallow alkyl quaternary ammonium compounds with bentonite clay. This combination is then treated with C8-C18-alkylbenzyldimethylammonium chloride to enhance its performance characteristics. The result is a versatile ingredient that not only controls viscosity but also imparts conditioning benefits, making it a valuable addition to a wide range of cosmetic products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Quaternium-18/Benzalkonium Bentonite:
One of the primary benefits of Quaternium-18/Benzalkonium Bentonite is its ability to control the viscosity of cosmetic products. In simpler terms, this ingredient helps to manage the thickness or thinness of a product. Whether you’re dealing with a lotion, cream, or gel, achieving the right consistency is crucial for both application and performance. By adjusting the viscosity, this ingredient ensures that the product spreads evenly on your skin, providing a smooth and pleasant experience. It also helps in stabilizing the formulation, preventing it from becoming too runny or too thick over time.
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-18/Benzalkonium Bentonite is generally considered safe for use in cosmetic products. 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-18/Benzalkonium Bentonite during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice.
Side effects and adverse reactions from this ingredient are relatively uncommon, but they can occur. It is recommended to perform a patch test before widespread usage to ensure there are no adverse reactions.
In terms of comedogenicity, Quaternium-18/Benzalkonium Bentonite has a rating of 2 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This means it has a low to moderate likelihood of clogging pores, which could be a concern for individuals prone to acne, blemishes, or breakouts.
