Description

Carbomer is a high molecular weight polymer of acrylic acid, cross-linked with polyalkenyl ethers or divinyl glycol, widely recognized for its exceptional thickening, suspending, and emulsifying properties. Its primary value lies in its ability to form clear, high-viscosity gels at low concentrations, making it a cornerstone ingredient for formulating stable and elegant products. This material is essential for manufacturers in the pharmaceutical, personal care, and cosmetic industries, where precise rheological control is critical.

Application

• Pharmaceutical Gels & Ointments: Used as a primary gelling agent in topical drug delivery systems, including analgesic, antibiotic, and antifungal gels, providing excellent bioadhesion and controlled release.
• Personal Care Products: Key thickener and stabilizer in toothpastes, shampoos, conditioners, shaving gels, and sunscreens, enhancing texture and product stability.
• Cosmetic Formulations: Essential for creating water-based gels, creams, lotions, and serums, offering superior clarity, non-greasy feel, and compatibility with active ingredients.
• Contact Lens Solutions: Serves as a lubricating and viscosity-enhancing agent in multi-purpose solutions and artificial tears.
• Household & Industrial Products: Employed in cleaning gels, polishes, and other specialty chemicals where thickening and suspension are required.

Quality Control

Our Carbomer is produced and tested under a strict quality management system. We offer grades compliant with major pharmacopoeial standards, including USP-NF, EP, and JP. Each batch is subjected to rigorous analytical testing for parameters such as viscosity, pH, residual solvents, and heavy metals to ensure batch-to-batch consistency and performance. A Certificate of Analysis (COA) is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent caking or degradation due to moisture absorption.
