For professionals in the cosmetic, pharmaceutical, and personal care industries, mastering the art of formulation is key to creating successful products. At the core of many stable and aesthetically pleasing formulations lies the rheology modifier, and Carbomer 940 stands out as a truly essential ingredient. This acrylic acid polymer is celebrated for its exceptional thickening, gelling, and stabilizing capabilities. NINGBO INNO PHARMCHEM CO.,LTD., as a leading manufacturer and supplier, is dedicated to providing formulators with in-depth knowledge about this powerful ingredient.

Carbomer 940, often recognized by its CAS number 9007-20-9, is a synthetic polymer known for its high molecular weight and light cross-linking. Supplied as a fine white powder, it transforms aqueous systems into viscous fluids or clear gels upon neutralization. Its primary function is to modify rheology – essentially controlling the flow and texture of a product. This makes it invaluable for creating the desired sensory experience consumers expect from their lotions, creams, gels, and suspensions. For formulators looking to buy this versatile ingredient, understanding its behavior is crucial for optimal results.

The thickening efficiency of Carbomer 940 is remarkable; it can significantly increase viscosity at very low concentrations, typically between 0.1% to 0.5%. This high efficiency translates into cost savings for manufacturers, making it an attractive option for bulk purchasing from a reliable supplier. When properly neutralized with bases like sodium hydroxide or triethanolamine, the polymer chains swell and create a complex network that impedes the flow of the liquid phase, thus increasing viscosity. This thickening power is fundamental to achieving the desired consistency in various personal care products.

As a gelling agent, Carbomer 940 excels in creating clear, aesthetically pleasing gels. The clarity is achieved when the polymer is fully hydrated and neutralized, allowing light to pass through unimpeded. This property is highly valued in products like hair styling gels, sanitizers, and certain cosmetic serums where a transparent appearance is desired. Manufacturers aiming to buy Carbomer 940 for gel applications can rely on its ability to deliver consistent clarity and viscosity when used according to recommended guidelines.

Stabilization is another key attribute of Carbomer 940. In formulations containing immiscible phases, such as oil-in-water emulsions, it acts as a stabilizer by preventing separation. It achieves this by suspending oil droplets within the aqueous phase, creating a stable emulsion that maintains its integrity over time. This is vital for product shelf-life and consumer satisfaction. For companies that need to buy dependable ingredients, a manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. ensures the consistent quality required for stable formulations.

Formulating with Carbomer 940 involves specific steps, including proper dispersion and neutralization. Ensuring the powder is evenly dispersed before neutralization is key to avoiding clumps and achieving a smooth final product. Understanding the pH sensitivity of Carbomer 940 (optimal performance typically above pH 5.0-6.0) is also crucial for maintaining viscosity. By partnering with NINGBO INNO PHARMCHEM CO.,LTD., you gain access not only to high-quality Carbomer 940 but also to valuable technical support and guidance from our experienced team.
