Description

Carbomer is a high molecular weight polymer of acrylic acid, widely recognized for its exceptional ability to absorb water and form clear, stable gels or viscous solutions. This rheology modifier is a cornerstone ingredient for formulators seeking precise control over product viscosity, texture, and stability. It is an indispensable material for manufacturers in the pharmaceutical, personal care, and cosmetic industries, where consistent performance and high purity are non-negotiable.

Application

• Topical Pharmaceutical Gels: Used as a primary gelling agent in medicated gels, creams, and ointments for controlled drug release and enhanced skin adherence.
• Personal Care & Cosmetics: Serves as a key thickener, suspending agent, and emulsion stabilizer in products like lotions, shampoos, sunscreens, and toothpastes.
• Ophthalmic Preparations: Employed in artificial tears and ophthalmic gels to provide lubrication and prolonged residence time on the eye surface.
• Hair Styling Products: Provides the necessary hold and film-forming properties in gels, mousses, and styling creams.
• Contact Lens Solutions: Acts as a viscosity-enhancing agent to improve comfort and lens wetting.
• Industrial Applications: Used as a thickening agent in various industrial formulations, including paints, adhesives, and printing inks.

Quality Control

Our Carbomer is manufactured and tested to meet stringent quality standards appropriate for pharmaceutical and cosmetic applications. We offer grades compliant with major pharmacopoeias, including USP-NF and EP. Every batch is supported by a comprehensive Certificate of Analysis (COA) detailing key parameters such as viscosity, pH, residual solvents, and heavy metal content, ensuring traceability and batch-to-batch consistency for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect the product's performance.
