Polyquaternium-2, identified by its CAS number 68555-36-2, is a synthetic cationic polymer that has carved out essential niches in both the personal care and industrial sectors. Its unique chemical properties lend themselves to a variety of functional benefits, making it a sought-after ingredient for formulators and manufacturers worldwide. As a dedicated supplier, we aim to provide a clear understanding of this versatile compound and how to source it effectively.

Chemical Profile and Key Properties

Polyquaternium-2 is characterized by its cationic nature, which is derived from quaternary ammonium groups within its polymer chain. This positive charge is fundamental to its interaction with negatively charged surfaces, such as hair and skin. Key properties include:

  • Appearance: Typically a colorless to light yellow viscous liquid.
  • Water Solubility: Readily dissolves in water, simplifying its incorporation into aqueous formulations.
  • pH Range: Generally stable within a pH range of 7.5-8.5.
  • Adhesion: Possesses strong adhesion to polar surfaces.
  • Conditioning: Excellent for imparting smoothness, reducing static, and improving manageability.

Diverse Application Spectrum

The functional benefits of Polyquaternium-2 translate into two main application areas:

  1. Personal Care: This is where Polyquaternium-2 shines as a conditioning agent. In hair care products like shampoos, conditioners, and styling aids, it provides detangling, anti-static properties, and a soft, smooth feel. It also finds use in skin care for its moisturizing and film-forming benefits, enhancing the sensory experience of lotions and creams. Buyers seeking cosmetic ingredients often look for Polyquaternium-2 for its proven performance.
  2. Industrial Electroplating: In the metal finishing industry, Polyquaternium-2 serves as a crucial leveling agent in electroplating baths, particularly alkaline zinc plating. It promotes uniform metal deposition, leading to enhanced brightness and corrosion resistance of the plated components. This industrial application highlights its role as a performance additive in critical manufacturing processes.

Sourcing Strategy: Quality and Value

When you need to buy Polyquaternium-2, selecting the right supplier is paramount. Manufacturers in China are often a primary source due to competitive pricing and large-scale production capabilities. However, it is vital to partner with suppliers who prioritize quality control, batch consistency, and reliable logistics. Look for companies that can provide comprehensive product data, including Certificates of Analysis (CoA), and have a solid reputation in the chemical supply chain.
