In the dynamic world of cosmetic and pharmaceutical formulation, selecting the right rheology modifier is paramount to achieving desired product performance, texture, and stability. Among the most versatile and widely used thickeners is Carbomer. This article aims to demystify Carbomer, focusing on Carbomer 940 and its distinctions from other carbomer homopolymers, guiding formulators in making informed choices. We'll also highlight the importance of sourcing from a reputable carbomer 940 supplier in China.

Understanding Carbomer Polymers

Carbomers are synthetic high-molecular-weight polymers of acrylic acid, cross-linked with polyalkenyl ethers. This cross-linking provides their characteristic ability to swell in water and form gels. The '940' in Carbomer 940 denotes specific rheological properties that make it highly sought after for applications requiring high viscosity and excellent clarity. Other common carbomer homopolymers include grades like 934, 941, and 971, each offering a slightly different profile in terms of viscosity, ion resistance, and shear thinning behavior.

Carbomer 940: Key Characteristics

Carbomer 940 is particularly valued for its:

  • High Viscosity: It provides substantial thickening even at low concentrations (typically 0.1-0.5%), making it very efficient.
  • Excellent Clarity: Forms transparent gels, which is crucial for many aesthetic-focused cosmetic products.
  • Low Ion Resistance: Less sensitive to electrolytes compared to some other grades, ensuring formulation stability in various conditions.
  • Short Rheological Property: Exhibits a gel structure that is less pseudoplastic, offering a distinct texture profile.

When considering carbomer 940 price, its efficacy at low usage levels often translates to cost-effectiveness for manufacturers.

Carbomer 940 vs. Other Homopolymers

While all carbomers are essentially cross-linked polyacrylic acid, the differences in cross-linking agents, degrees of cross-linking, and manufacturing processes lead to variations in their final properties. For instance, Carbomer 941 might offer longer rheological properties but lower viscosity compared to 940. Carbomer 971 is often utilized for sustained-release applications. The choice depends heavily on the intended application and the desired final product characteristics. Understanding these differences is key to selecting the best carbomer for cosmetic formulations.
