Quaternium 73 is a quaternary ammonium compound that is a cationic surfactant. Quaternary ammonium compounds are known for their antibacterial, conditioning and surfactant properties, making them valuable ingredients in a variety of personal care, cosmetic and household products.
Quaternium 73 is widely used in hair care products such as shampoo, conditioner, hair mask, and styling products due to its excellent conditioning properties. As a cationic surfactant, it carries a positive charge, allowing it to adsorb to the negatively charged surface of the hair fiber. This adsorption creates a film or coating on the hair shaft that helps smooth the cuticle, reduce friction, and improve hair's manageability. Quaternium 73 also acts as an effective antistatic agent in hair care formulations. Quaternium 73 helps neutralize static charges on the hair surface, preventing static build-up and reducing flyaways. Quaternium 73 has smoothing properties that allow it to be used in leave-in conditioners, softeners and hair sprays designed to easily detangle wet or tangled hairQuaternium 73 also acts as an emulsifier and stabilizer in cosmetic formulations Agent that helps mix incompatible ingredients like water and oil together to form a stable, uniform emulsion. It improves the texture, consistency and appearance of emulsified products such as creams, lotions and conditioners, enhancing their spreadability, moisturizing properties and sensory attributes. Quaternium 73 may exhibit preservative-enhancing effects when combined with other antimicrobial agents in cosmetic formulations. By enhancing the effectiveness of preservatives, they help inhibit the growth of bacteria, fungi and other microorganisms, thereby extending the shelf life and microbial stability of cosmetics.
