Polyquaternium-11 PQ-11 CAS 53633-54-8 – Powerful Film-Forming Conditioning Polymer for Hair Care

BLIT Chemical factory Polyquaternium-11 PQ-11 (CAS 53633-54-8) is a cationic quaternary ammonium polymer widely used in personal care formulations, especially in hair care and styling products. Known for its excellent film-forming and conditioning performance, Polyquaternium-11 helps improve hair manageability, softness, and shine while providing long-lasting hold and antistatic properties.

Polyquaternium-11 is typically a clear to slightly cloudy viscous liquid solution. It exhibits good compatibility with a wide range of surfactants and cosmetic ingredients, making it a versatile conditioning polymer suitable for products such as shampoos, conditioners, hairsprays, gels, and styling mousses. Its unique cationic charge allows it to effectively deposit on negatively charged hair fibers, forming a thin, flexible film that improves dry and wet styling, reduces static, enhances hair smoothness, and helps maintain long-lasting styling results. It also helps stabilize formulations and improves the sensory experience of the finished product.

From a formulation standpoint, Polyquaternium-11 is valued for its stability across a wide pH range and its compatibility with both anionic and amphoteric surfactant systems. This versatility allows cosmetic chemists to incorporate it into a broad range of cleansing and conditioning products. BLIT Chemical manufactures Polyquaternium-11 under controlled production conditions to ensure consistent viscosity, reliable performance, and stable quality for global cosmetic manufacturers.

PQ-11 Applications

Hair Conditioning Agent in Shampoos

Polyquaternium-11 is widely used in conditioning shampoos because it deposits onto hair fibers during washing.

Key benefits include:

• Improved wet and dry combing
• Enhanced softness and smoothness
• Reduced static electricity
• Increased hair shine and manageability

The polymer creates a thin conditioning film that improves the overall hair feel without causing heavy buildup.

Film-Forming Polymer in Hair Styling Products

Polyquaternium-11 functions as an excellent film-forming agent in styling formulations such as:

• Hair sprays
• Styling gels
• Hair mousse
• Leave-in conditioners

Its flexible polymer film helps maintain hairstyle structure while preserving natural hair movement. This property makes it highly valued in professional salon styling products.

Antistatic and Detangling Ingredient

Because Polyquaternium-11 carries a positive charge, it neutralizes the negative charge that naturally accumulates on hair fibers. This property provides several benefits:

• Reduced static electricity
• Improved detangling performance
• Enhanced smoothness and manageability
• Better distribution of conditioning ingredients

These characteristics make Polyquaternium-11 particularly useful in conditioning systems designed for damaged or chemically treated hair.

Why Manufacturers Choose BLIT CHEMICAL Polyquaternium-11

Cosmetic manufacturers select Polyquaternium-11 for several reasons:

• Excellent film-forming ability
• Strong conditioning and antistatic performance
• Compatibility with many surfactants
• Suitable for rinse-off and leave-on products
• Stable across common cosmetic formulation ranges

Because of these advantages, Polyquaternium-11 remains a key ingredient in modern hair care formulations worldwide.
