For formulators aiming to create effective and appealing products, a deep understanding of the ingredients they use is crucial. Poly(Acrylic Acid) (CAS 9007-20-9), commonly known as Carbomer, is a versatile polymer with a unique set of chemical properties that lend themselves to a wide range of applications. NINGBO INNO PHARMCHEM CO.,LTD. provides insights into these properties and their practical implications.

At its core, Poly(Acrylic Acid) is a high-molecular-weight polymer featuring carboxylic acid groups along its chain. These groups are key to its functionality, particularly its ability to form gels when dispersed in water and neutralized. The pH dependency of these carboxylic acid groups means that PAA typically requires a neutralizing agent, such as triethanolamine or sodium hydroxide, to achieve its full thickening potential and clarity. This makes it an excellent poly(acrylic acid) thickener agent.

The polymer's ability to absorb and swell in water is another critical property. When hydrated, PAA can swell to many times its original volume, creating highly viscous solutions or gels. This characteristic is fundamental to its role as a rheology modifier in cosmetic and pharmaceutical formulations, contributing to desired textures and flow properties. Its utility as a carbomer for gels and lotions is a testament to this property.

Carbomer also acts as an effective suspending, dispersing, and emulsifying agent. It helps to keep solid particles evenly distributed in liquid formulations and stabilizes emulsions by preventing oil and water phases from separating. This functionality is vital for product homogeneity and appearance. As a poly(acrylic acid) suspending agent, it ensures consistent product performance.

Formulators considering to buy poly(acrylic acid) online should also be aware of its compatibility with other ingredients. While generally stable, PAA can be sensitive to high concentrations of electrolytes and strong acids, which can reduce its thickening efficiency. Understanding these poly(acrylic acid) chemical properties allows for optimized formulation design.

The different grades of Carbomer available, such as Carbomer 940 and Carbomer 980, offer varying degrees of cross-linking and molecular weight, influencing their thickening power and application suitability. NINGBO INNO PHARMCHEM CO.,LTD. offers a selection of Poly(Acrylic Acid) products, catering to diverse formulator needs across the cosmetic, pharmaceutical, and industrial sectors.

By understanding and leveraging the unique chemical properties of Poly(Acrylic Acid), formulators can create innovative products that meet consumer demands for texture, stability, and efficacy. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing the high-quality ingredients and information needed to achieve these goals.
