Polyquaternium-64 is a synthetic, water-soluble quaternary ammonium polymer widely utilized in the cosmetic industry, known for its conditioning and film-forming properties [1]. It is a cationic polymer, meaning it carries a positive charge, which allows it to effectively bind to negatively charged surfaces like hair and skin [2]. This binding action contributes to its desirable effects in personal care formulations.

The production of polyquaternium-64 generally involves the polymerization of specific monomers under controlled conditions. The precise details of the synthesis are typically proprietary to the manufacturer, however, the process includes quaternization to impart the cationic charge to the polymer [3]. Quality control measures, such as monitoring molecular weight and purity, are crucial during production to ensure batch-to-batch consistency.

Polyquaternium-64 offers several beneficial properties, it enhances manageability and reduces static electricity in hair [4]. The polymer forms a thin, flexible film on the hair shaft, which helps to smooth the cuticle and impart a silky feel [5]. In skin care applications, it provides moisturization and a non-tacky feel, enhancing the overall sensory experience of the product [6].

This ingredient finds application in a variety of hair care products, including shampoos, conditioners, styling gels, and hairsprays, and it improves detangling and combability, while providing a smooth and conditioned feel [7]. In skin care, polyquaternium-64 is used in lotions, creams, and serums for its moisturizing and film-forming characteristics, leaving the skin feeling soft and hydrated [8]. It also can be utilized in leave-on products due to its non-greasy nature.

Polyquaternium-64 is typically packaged in plastic drums or containers to maintain its integrity during storage and transportation. It should be stored in a cool, dry place, away from direct sunlight and extreme temperatures, and transportation should adhere to standard practices for chemical substances, ensuring that containers are properly sealed and labeled to prevent leaks or contamination [9].
