The world of polymers is vast, and within the family of carbomers, different grades exist to serve specific purposes. Carbomer 940 is a widely recognized and utilized member, but formulators often need to understand how it compares to other carbomer grades to make the most informed purchasing decisions. As a leading supplier, we aim to provide clarity on these distinctions to help you buy the right Carbomer 940 or its counterparts.

Carbomers are essentially cross-linked polyacrylic acid polymers, differentiated by their molecular weight, cross-linking agents, and manufacturing processes. These differences influence their performance characteristics such as thickening efficiency, gel clarity, electrolyte tolerance, and dispersibility. While all carbomers are effective rheology modifiers, their specific applications may vary.

Carbomer 940 is known for its excellent thickening efficiency and ability to produce sparkling clear gels. It's a workhorse ingredient, widely used in cosmetics for lotions, creams, and hair gels, and in pharmaceuticals for topical medications and suspensions. Its versatility makes it a popular choice for many standard formulations. When formulators search to buy Carbomer 940, they are often looking for this reliable, all-around performance.

Other common grades include Carbomer 980, which offers similar thickening and clarity but might have slightly different rheological profiles or electrolyte tolerance. Carbomer 340 and 380 are also available, often differing in their cross-linking density or molecular weight, which can affect their viscosity build and shear thinning properties. For instance, higher cross-linking might lead to increased viscosity but potentially reduced clarity or increased sensitivity to electrolytes.

There are also specialized carbomers, such as carbomer copolymers and interpolymers, which are designed for specific functionalities. For example, some carbomers are engineered for enhanced dispersion (often termed 'easy-dispersing' grades) or improved stability in challenging formulations containing high levels of surfactants or active ingredients. While Carbomer 940 is highly effective, these specialized grades might offer advantages in niche applications.

When considering which grade to purchase, formulators should evaluate their specific needs: Is extreme clarity essential? Does the formulation contain high levels of electrolytes? Is ease of dispersion a primary concern? The answers to these questions will guide the selection. For many standard applications requiring good thickening, stability, and clarity, Carbomer 940 remains a top choice due to its proven performance and competitive price from reliable manufacturers in China.
