Description

Carbomer 934 is a high molecular weight, cross-linked polyacrylic acid polymer widely recognized as a superior rheology modifier and gelling agent. Its primary value lies in its exceptional ability to form clear, high-viscosity gels at low concentrations, even in neutralized aqueous systems. This product is essential for formulators in the pharmaceutical, personal care, and cosmetic industries who require reliable, non-toxic, and efficient thickening, suspending, and stabilizing performance. Carbomer 934 CAS NO 9007-16-3 is a key ingredient for creating stable emulsions, lotions, creams, and topical gels with desirable sensory properties.

Application

• Pharmaceutical Topicals: As a primary gelling agent in water-based gels for dermatological creams, ointments, and transdermal delivery systems.
• Personal Care & Cosmetics: For thickening and stabilizing a wide range of products including facial cleansers, moisturizing lotions, sunscreens, shaving gels, and hair styling products.
• Ophthalmic Preparations: Used to increase the viscosity and bioadhesion of eye drops and artificial tear solutions, improving residence time on the corneal surface.
• Oral Care Products: As a binder and thickener in toothpastes and oral gels to provide the desired consistency and stability.
• Antiseptic & Medicated Gels: For formulating clear, elegant gels containing active ingredients like benzoyl peroxide, clindamycin, or anti-itch compounds.
• Household & Industrial Products: In specialty cleaners, polishes, and other aqueous formulations requiring rheological control.

Quality Control

Our Carbomer 934 is manufactured and tested to meet stringent quality standards, including relevant pharmacopoeial monographs. Each batch is subjected to rigorous analytical testing to ensure consistency in viscosity, pH, residue on ignition, and heavy metal content. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing the specific results against agreed specifications. We support compliance with cGMP, ISO 9001, and REACH requirements for our global clientele.

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.
