Carbomer 940 (CAS 9007-20-9) is a synthetic polymer that has become an indispensable component in numerous industrial and consumer products, most notably in cosmetics and pharmaceuticals. Its remarkable ability to thicken and stabilize aqueous solutions stems from its unique chemical structure and polymerization process. Understanding these scientific underpinnings is crucial for formulators and procurement managers looking to source high-quality Carbomer 940. NINGBO INNO PHARMCHEM CO.,LTD., as a prominent manufacturer and supplier in China, is pleased to share insights into the science behind this versatile ingredient.

At its core, Carbomer 940 is a high molecular weight polymer derived from acrylic acid. The synthesis typically involves free-radical polymerization of acrylic acid, often with a cross-linking agent to create a three-dimensional polymer network. This cross-linking is what gives Carbomer 940 its distinctive properties. When dispersed in water and neutralized, the polymer chains unfurl and form a tightly cross-linked hydrogel. This structure allows it to absorb and retain significant amounts of water, leading to a dramatic increase in viscosity. The result is a clear, colorless gel with a smooth consistency, making it an ideal thickening agent for a wide array of applications.

The '940' designation in Carbomer 940 refers to specific characteristics related to its molecular weight and cross-linking density, which influence its gelling efficiency and rheological profile. These properties are carefully controlled during the manufacturing process to ensure batch-to-batch consistency. For industries that require precise formulation control, such as cosmetics and pharmaceuticals, sourcing Carbomer 940 from a reputable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. is essential. We ensure our production processes adhere to strict quality control measures to deliver a product that consistently meets specifications.

Beyond thickening, Carbomer 940 also functions as an excellent suspending and dispersing agent. Its viscous matrix can hold solid particles in suspension, preventing them from settling out in formulations. This is vital for products containing insoluble ingredients, ensuring uniform distribution and product integrity. The ability to purchase Carbomer 940 in bulk from our China-based facilities allows businesses to scale their production while maintaining cost-effectiveness. Our manufacturing capacity is geared to meet the demands of global markets.

The manufacturing of Carbomer 940 is a sophisticated process that requires specialized equipment and expertise. Free radical polymerization, often carried out in suspension or solution, is a common method. Careful control of monomer concentration, initiator levels, temperature, and reaction time are critical to achieving the desired polymer characteristics. NINGBO INNO PHARMCHEM CO.,LTD. invests in advanced manufacturing technologies and quality assurance protocols to produce Carbomer 940 that excels in performance and purity. We invite potential buyers to inquire about our manufacturing capabilities and to buy Carbomer 940 directly from us.
