Description

Carbomer CAS NO 9062-04-8 is a high molecular weight polymer of acrylic acid, widely recognized as a superior rheology modifier and gelling agent. Its primary value lies in its exceptional ability to form clear, stable, and elegant gels or viscous aqueous solutions at low concentrations, making it indispensable for precise viscosity control. This product is essential for formulators in the pharmaceutical, personal care, and cosmetic industries who require reliable, high-performance excipients for products ranging from topical gels and creams to ophthalmic solutions and hair styling products.

Application

• Pharmaceutical Gels and Creams: Used as a primary gelling agent in topical drug delivery systems, including analgesic, anti-inflammatory, and antifungal formulations, providing excellent skin feel and controlled release.
• Personal Care & Cosmetics: Serves as a key thickener and stabilizer in products such as moisturizing lotions, sunscreens, shampoos, conditioners, and facial cleansers to achieve desired texture and suspension of particles.
• Ophthalmic Preparations: Employed in artificial tear solutions and medicated eye drops to enhance viscosity, improve corneal contact time, and increase patient comfort.
• Hair Styling Products: Provides the necessary hold and film-forming properties in gels, mousses, and sprays without leaving a sticky residue.
• Oral Care Products: Functions as a binder and thickener in toothpastes and oral gels to ensure stable consistency and optimal product performance.
• Industrial Applications: Acts as a suspending agent, thickener, or stabilizer in various industrial formulations, including household cleaners and polishes.

Quality Control

Our Carbomer is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. We offer grades that comply with major international pharmacopoeial standards, including USP-NF and EP. Each batch undergoes rigorous analytical testing for critical parameters such as viscosity, pH, residual solvents, and heavy metals. A comprehensive Certificate of Analysis (COA) is provided with every shipment to guarantee product integrity and support your regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect performance.
