In the pharmaceutical industry, excipients play a vital role in the efficacy, stability, and patient compliance of drug formulations. Carbomer 940, a synthetic polymer derived from acrylic acid, stands out as a critical pharmaceutical excipient, primarily utilized for its remarkable rheological properties. As a leading manufacturer and supplier of this high-quality poly(acrylic acid), we provide pharmaceutical companies with a reliable ingredient for advanced drug delivery systems and stable formulations.

Carbomer 940 (CAS 9003-01-4) is a cross-linked polyacrylic acid polymer widely recognized for its ability to thicken aqueous solutions, form gels, and act as a suspending and emulsifying agent. Its utility in pharmaceuticals stems from its capacity to control drug release rates, enhance bioadhesion, and improve the overall texture and stability of both topical and oral dosage forms. For pharmaceutical researchers and procurement managers seeking reliable suppliers, understanding the specific benefits of Carbomer 940 is key.

One of the primary pharmaceutical applications of Carbomer 940 is in controlled-release formulations. By forming a viscous gel matrix, it can encapsulate active pharmaceutical ingredients (APIs), modulating their dissolution and release over time. This property is invaluable for extending the therapeutic effect of medications, reducing dosing frequency, and improving patient adherence. Lightly cross-linked Carbomer grades, like certain variations of Carbomer 940, are often more efficient in controlling drug release than their more highly cross-linked counterparts, offering formulators flexibility in designing release profiles.

Furthermore, Carbomer 940 is frequently employed in topical and semi-solid pharmaceutical preparations such as creams, gels, lotions, and ointments. Its thickening and suspending capabilities ensure uniform distribution of APIs, prevent sedimentation of particles, and provide a desirable texture and feel upon application. For manufacturers requiring bulk quantities of pharmaceutical-grade Carbomer, sourcing from a reputable supplier like us ensures consistent quality and compliance with regulatory standards. We offer competitive pricing for businesses looking to buy Carbomer for their pharmaceutical needs.

The stability of Carbomer 940 in various formulation environments also contributes to its appeal. While sensitive to high electrolyte concentrations, it remains stable across a range of pH values and can be sterilized via autoclaving or gamma irradiation with minimal impact on its performance, provided appropriate handling procedures are followed. Its low toxicity profile and excellent safety record further solidify its position as a preferred excipient in pharmaceutical manufacturing.

As a dedicated supplier of pharmaceutical intermediates and excipients, we are committed to supporting innovation in drug delivery. Whether you are developing advanced topical treatments, oral dosage forms requiring precise release kinetics, or stable suspensions, our Carbomer 940 offers a reliable and cost-effective solution. We invite pharmaceutical professionals to contact us to discuss their specific formulation challenges and to explore our bulk purchasing options for Carbomer 940.
