polyquer

Polyquer is a collective term used to describe a group of synthetic polymers that are characterized by their positive electrical charge. These cationic polymers are often employed in a variety of applications due to their ability to interact with negatively charged surfaces and molecules.

The specific chemical structure of polyquers can vary widely, but they typically feature repeating units containing quaternary ammonium groups. These positively charged groups are responsible for the polymer's electrostatic attraction to anionic substances. Common examples of polyquer chemistries include polyquaternium-1, polyquaternium-10, and polyquaternium-11, among many others, each with slightly different properties and applications.

In personal care products, polyquers are frequently used as conditioning agents in shampoos, conditioners, and styling products. Their positive charge allows them to bind to the negatively charged surface of hair, reducing static, improving combability, and imparting a smooth feel. They can also be found in skincare formulations, where they act as film-formers and moisturizers.

Beyond personal care, polyquers find use in industrial settings. They can function as flocculants in water treatment, helping to aggregate suspended particles for easier removal. Additionally, they are employed in the paper industry to improve wet strength and retention of fillers and fibers. Their antimicrobial properties also lead to applications in disinfectants and sanitizers. The efficacy and specific function of a polyquer depend heavily on its molecular weight, charge density, and chemical structure.
