Polyquaternium 4

Polyquaternium-4 (CAS 92183-41-0) is a cationic cellulose-derived polymer used as a conditioning and film-forming agent across personal care and industrial applications. The quaternary ammonium groups along its backbone allow it to bind to negatively charged surfaces.

This unique chemical structure makes it highly effective for deposition and retention on hair, skin, and various fibrous substrates. In hair care formulations such as shampoos and conditioners, it improves wet combability and reduces static.

The polymer enhances overall manageability and is frequently found in leave-in treatments. Rinse-off and leave-on skin care products use it as a lightweight film former that improves texture without leaving a heavy or greasy residue.

In textile processing, it is applied as a surface modifier to improve softness and antistatic performance. It also aids in dye retention on both natural and synthetic fibers, ensuring a more durable and high-quality finish for manufacturers.

Paper and nonwoven manufacturers use it to modify surface charge and improve wet strength or bonding in finished sheets. This versatility makes it a staple ingredient in industrial chemical processing and specialty paper production.

Polyquaternium-4 is typically supplied as an aqueous solution or gel, with active polymer content varying by grade. Both cosmetic-grade and technical-grade material are available to meet personal care and industrial processing requirements.

Buyers should confirm active content, viscosity specification, and the specific preservation system when evaluating supplier offerings. Ensuring the material meets necessary quality benchmarks is essential for consistent formulation performance.
