Polyquaternium-44

What is Polyquaternium-44?

Polyquaternium-44 is a synthetic, water-soluble cationic polymer composed of quaternized acrylic and methacrylamide units. Primarily featured in hair care formulations such as conditioners, detanglers, and styling gels, it functions through electrostatic attraction to the hair's negatively charged surface. This deposition creates a substantive layer that neutralizes static charges, minimizes inter-fiber friction, and deposits a sheer film. The result is enhanced slip for easier combing, reduced tangles, and improved style retention during wear. Its mild, non-greasy profile makes it suitable for both rinse-off and leave-on products, contributing to overall hair health appearance without heavy residue.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Antistatic agent
Reduces static electricity and flyaways by improving surface conductivity, enhancing hair manageability and smoothness in conditioners and styling products.
Film former
Creates a continuous film on skin or hair to improve wear, water resistance, transfer resistance, shine, or hold in sunscreens, makeup, and styling products.
Hair conditioning
Improves softness, shine, and manageability by reducing friction and static; commonly achieved with cationic agents, silicones, oils, or conditioning polymers.

Benefits

Reduces static electricity for fewer flyaways and smoother styling.

Enhances hair softness and detangling for easier manageability.

Forms a lightweight film to boost shine and hold in products.
