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 critical ingredient for achieving precise texture, stability, and delivery in a wide range of formulated products. It is an essential raw material for manufacturers in the pharmaceutical, personal care, and household chemical industries seeking reliable thickening, suspending, and emulsifying performance.

Application

• Topical Pharmaceutical Gels & Creams: Used as a primary gelling agent in dermatological preparations, transdermal drug delivery systems, and antiseptic or analgesic gels for its excellent bioadhesive properties and compatibility with active ingredients.
• Personal Care & Cosmetics: Serves as a key thickener and stabilizer in water-based formulations such as facial cleansers, moisturizing lotions, sunscreens, shampoos, conditioners, and styling gels to provide desirable viscosity and sensory feel.
• Oral Care Products: Employed in toothpastes and oral gels to provide the necessary rheology for suspension of abrasives and actives, ensuring consistent texture and product stability.
• Household & Industrial Products: Acts as a thickener in liquid soaps, detergents, and surface cleaners to control viscosity, prevent splashing, and improve cling to vertical surfaces.
• Ophthalmic Preparations: Utilized in artificial tear solutions and medicated eye drops to enhance viscosity, prolong corneal contact time, and improve patient comfort.

Quality Control

Our Carbomer is manufactured under a strict quality management system. We offer grades that can comply with major pharmacopoeial standards, including USP-NF and EP, for critical applications. Every batch undergoes rigorous testing for parameters such as viscosity, pH, residual solvents, and heavy metals. A comprehensive Certificate of Analysis (COA) is provided with each shipment to ensure traceability and compliance with your specifications.

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.
