Description

Polyquaternium-2 is a synthetic cationic polymer belonging to the quaternary ammonium compound family, widely recognized for its potent conditioning and antistatic properties. Its primary value lies in its ability to effectively neutralize negative charges, improve manageability, and provide a smooth, soft feel to various substrates. This makes it an essential ingredient for manufacturers in the personal care, home care, and industrial chemical sectors seeking high-performance film-forming and substantivity agents.

Application

• Hair Care Formulations: A key conditioning agent in shampoos, conditioners, and hair masks to impart detangling, softness, and shine while reducing static flyaway.
• Skin Care & Cosmetics: Used in creams, lotions, and makeup products as an emulsifier and to enhance skin feel, providing a smooth, non-greasy afterfeel.
• Fabric Care & Softeners: Incorporated into liquid fabric softeners and dryer sheets to reduce static cling, improve fabric softness, and provide a pleasant fragrance substantivity.
• Industrial Applications: Serves as a flocculant, retention aid, and drainage aid in paper manufacturing processes.
• Water Treatment: Acts as a clarifying agent and coagulant aid for the removal of suspended solids in various water treatment systems.

Quality Control

Our Polyquaternium-2 is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance. Quality is verified through a series of analytical tests including assay, viscosity, pH, and residual monomer content. Certificates of Analysis (COA) documenting full specifications are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. For long-term storage, ensure the container is kept tightly sealed to prevent moisture absorption or contamination.
