For cosmetic chemists and formulators, understanding the intricate properties of ingredients like Polyquaternium-22 is key to creating innovative and effective products. NINGBO INNO PHARMCHEM CO.,LTD. provides insights into the chemical nature and formulation advantages of this versatile amphoteric polymer.

Polyquaternium-22 is a copolymer of acrylic acid and dimethyldiallylammonium chloride. This unique structure grants it amphoteric characteristics, meaning it can exhibit both anionic and cationic properties depending on the pH of the surrounding medium. This ampholytic nature is crucial to its broad efficacy across diverse product types and pH conditions, ranging from 1 to 14.

As a cationic polymer, Polyquaternium-22 possesses a positive charge. This charge is what allows it to strongly adsorb onto negatively charged surfaces such as hair and skin. This substantivity is the foundation for its excellent conditioning, antistatic, and film-forming abilities. In hair care, this interaction smooths the cuticle, reduces friction, and prevents static electricity. In skin care, it contributes to a protective, moisturizing film.

The formulation versatility of Polyquaternium-22 is a significant advantage. It demonstrates excellent compatibility with a wide range of surfactants, including anionic and amphoteric types, which are commonly found in shampoos and cleansers. This compatibility ensures that formulators can create stable, high-performance products without encountering unwanted interactions or precipitation.

The typical usage concentrations for Polyquaternium-22 vary depending on the application. In shampoos and conditioners, a concentration of around 1.0% is often recommended to impart significant conditioning benefits. For other leave-on or rinse-off formulations like lotions or body washes, concentrations up to 3.0% may be used to enhance skin feel and moisturization. NINGBO INNO PHARMCHEM CO.,LTD. advises formulators to conduct their own efficacy and stability testing to determine optimal levels.

Furthermore, its physical form—typically a clear to yellow, viscous liquid—makes it easy to incorporate into various cosmetic matrices. Whether it's a low-viscosity spray or a high-viscosity cream, Polyquaternium-22 can be effectively integrated. Its role as a film former also means it can contribute to the overall texture and stability of emulsions and surfactant systems.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to supporting formulators by providing high-quality Polyquaternium-22 and detailed technical information. Understanding its chemical structure and functional properties empowers cosmetic chemists to harness its full potential in creating innovative and consumer-preferred personal care products.
