Product: Polyquaternium-11 (PQ-11)
Rchem Polyquaternium-11 is a high-purity, cationic copolymer supplied as a viscous liquid or a free-flowing powder, renowned for its exceptional holding and styling properties. This versatile polymer is a cornerstone of firm-hold hair styling systems, where it acts as a primary film-forming agent. It creates a clear, flexible, and non-tacky film upon drying, providing long-lasting hold, excellent humidity resistance, and remarkable curl retention for a wide range of styling products.

Frequently Asked Questions:
What is the primary function of Polyquaternium-11, and how does it differ from other styling polymers?
Its primary function is to provide a strong, flexible hold. Unlike some older acrylic-based polymers that can become brittle and flaky, PQ-11 is known for forming a clearer, more flexible film with better humidity resistance and less tackiness. It is often considered a benchmark for high-performance styling.
PQ-11 is supplied in an acidic form to keep it stable and soluble. Neutralizing it with a base (like AMP, TEA, or Triethanolamine) converts the acidic groups into carboxylate salts, which causes the polymer chains to uncoil and thicken the solution dramatically, allowing it to form a proper gel network and a functional film upon drying.
Why is neutralization required for PQ-11, and what is used?
Yes, it can be combined. However, formulators must be cautious. Combining a cationic styling polymer (PQ-11) with another cationic conditioner (PQ-10) can sometimes lead to over-conditioning or a heavy feel. They are often used in different product phases or balanced carefully to achieve both hold and softness.
Can Polyquaternium-11 be combined with other conditioning polymers like PQ-10?
When formulated correctly at the right concentration and with appropriate plasticizers/humectants, PQ-11 has a low tendency to flake. Flaking often occurs if the film is too thick and brittle, which can be mitigated by ensuring proper neutralization and adding ingredients like glycerin or propylene glycol to maintain film flexibility.
Is PQ-11 prone to flaking?
For the liquid form, store in a cool place and avoid freezing. For the powder, store in a cool, dry place. It must be fully neutralized to achieve its intended holding power and viscosity. Pre-disperse or dissolve it in water before adding other ingredients and adjust
