In the complex world of cosmetic formulation, ingredient compatibility is paramount to achieving stable, effective, and aesthetically pleasing products. Polyquaternium-7, a widely used cationic copolymer, stands out for its remarkable compatibility, particularly with anionic surfactant systems – the backbone of many shampoos, body washes, and cleansers.

Anionic surfactants are known for their excellent cleansing and foaming properties. However, their negative charge can sometimes lead to incompatibilities with other ingredients, potentially affecting product stability, viscosity, and overall performance. This is where Polyquaternium-7 shines. As a positively charged polymer, it is designed to effectively interact with and stabilize negatively charged anionic surfactants.

This synergistic relationship allows formulators to create products that benefit from the strong cleansing power of anionic surfactants while simultaneously incorporating the conditioning, film-forming, and sensory-enhancing properties of Polyquaternium-7. The result is often enhanced foam quality – making it richer and creamier – increased viscosity, and an improved conditioning feel on both hair and skin, all without compromising product integrity.

The stability that Polyquaternium-7 brings to formulations is a significant advantage for manufacturers. It helps to prevent phase separation, maintain a consistent texture, and ensure that the product performs as intended throughout its shelf life. This is particularly crucial for high-volume production and for brands aiming for consistent product quality.

At NINGBO INNO PHARMCHEM CO.,LTD., we recognize the importance of ingredient synergy and stability.
