Carbomer 940, a synthetic polymer with the CAS number 9003-01-4, is a fundamental ingredient in numerous industries, most notably cosmetics, personal care, and pharmaceuticals. Its efficacy stems from its unique chemical structure and properties, which allow it to act as a powerful thickening agent, gelling agent, and stabilizer. Understanding the science behind Carbomer 940 is crucial for formulators aiming to create high-performance products. As a dedicated manufacturer and supplier, we are pleased to share insights into this versatile material.

At its core, Carbomer 940 is a polymer derived from acrylic acid. It is created through a process of polymerization and cross-linking, typically with polyalkenyl ethers such as allyl sucrose or pentaerythritol allyl ethers. This cross-linking creates a high-molecular-weight polymer network that has an exceptional capacity to absorb water. When dispersed in water, these polymers swell significantly, forming a gel-like structure. This swelling is pH-dependent; typically, neutralization with an alkaline agent (like sodium hydroxide or triethanolamine) is required to deprotonate the carboxylic acid groups, leading to increased chain repulsion and thus, significant thickening.

The rheological properties of Carbomer 940 are a key reason for its widespread use. It can dramatically increase the viscosity of aqueous solutions, even at low concentrations (often between 0.2% and 1.0%). This thickening effect is crucial for achieving desired product consistencies, from light serums to thick creams. Moreover, Carbomer 940 is known for its ability to create clear gels, which is highly valued in cosmetic and pharmaceutical formulations where visual appeal and clarity are important. When formulators decide to buy Carbomer 940, they are investing in a reliable rheology modifier that ensures product stability and performance.

The applications of Carbomer 940 are extensive. In the cosmetic industry, it is a staple for creating lotions, creams, gels, and serums, enhancing their texture, spreadability, and stability. It helps suspend solid particles and active ingredients, preventing them from settling and ensuring uniform distribution. In the pharmaceutical sector, Carbomer 940 is used in topical medications, ointments, and eye drops, where its thickening and stabilizing properties aid in controlled drug delivery and improved patient comfort. Understanding the Carbomer 940 price from a reputable supplier is essential for cost-effective product development.
