At NINGBO INNO PHARMCHEM CO.,LTD., we are passionate about the science behind our ingredients. Carbomer 940 is a prime example of a polymer with remarkable scientific properties that translate into tangible product benefits. Its prowess as a gelling agent is well-established, making it a preferred choice for formulators across various industries. Let's explore the science that makes Carbomer 940 so effective.

The core of Carbomer 940's gelling ability lies in its molecular structure: a high molecular weight, cross-linked polyacrylic acid polymer. When dispersed in water, these long polymer chains are coiled and entangled. However, in its dry, acidic state, it has limited thickening power. The crucial step to unlock its gelling potential is neutralization. The addition of a base, such as Triethanolamine (TEA) or Sodium Hydroxide, raises the pH of the dispersion.

As the pH increases, the carboxylic acid groups along the polymer chains become deprotonated, acquiring negative charges. These negative charges repel each other, causing the polymer chains to uncoil and expand. The cross-linking agents prevent the chains from fully separating, instead creating a three-dimensional network that traps water molecules. This intricate network is what forms the gel, giving the formulation its characteristic viscosity and consistency. The Carbomer 940 formulation guide highlights that precise pH control is essential for optimal gel formation.

The benefits of using Carbomer 940 for gel formulations are significant. It allows for the creation of clear, stable gels with excellent viscosity. This is invaluable in cosmetic products like hair gels, facial serums, and hand sanitizers, where texture and clarity are key. For pharmaceutical applications, its ability to form a viscous gel improves the retention of active ingredients, enhancing therapeutic efficacy, particularly in eye care and topical medications.
