Description

Carbomer 956 is a high molecular weight, cross-linked polyacrylic acid polymer widely used as a rheology modifier and gelling agent. Its primary value lies in its exceptional ability to create clear, elegant, and stable gels and viscous solutions at low concentrations, even in the presence of electrolytes. This makes it a critical ingredient for formulators in the personal care, pharmaceutical, and cosmetic industries seeking superior sensory profiles and product stability. Carbomer 956 CAS NO 134499-38-0 is particularly valued for its neutralized gel clarity and smooth texture.

Application

• Personal Care Gels: Primary gelling agent for clear and opaque hair styling gels, alcohol-free gels, and shower gels.
• Topical Pharmaceutical Preparations: Used as a suspending and gelling agent in dermatological gels, creams, and ointments for controlled API release.
• Cosmetic Serums & Lotions: Provides excellent viscosity control and suspension of particles in facial serums, moisturizers, and sunscreen formulations.
• Toothpaste & Oral Care: Acts as a binder and thickener to provide the desired rheology and stability in toothpaste and oral gels.
• Household & Industrial Products: Utilized as a thickener and stabilizer in cleaning gels, polishes, and other aqueous-based specialty chemicals.

Quality Control

Our Carbomer 956 is manufactured under a strict quality management system. It is tested against relevant pharmacopeial standards where applicable, including viscosity, pH, residue on ignition, and heavy metals. A comprehensive Certificate of Analysis (COA) detailing purity, physical characteristics, and microbiological quality is provided with each batch to ensure consistency and compliance with your formulation requirements.

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 opening to prevent moisture absorption and caking.
