Description

Sodium Carbomer CAS NO 73298-57-4 is the sodium salt of cross-linked polyacrylic acid, functioning as a highly efficient and versatile rheology modifier and suspending agent. Its primary value lies in its ability to create stable, elegant gels and creams with excellent clarity and skin feel, even at neutral pH, without the need for neutralization. This product is essential for formulators in the cosmetics, personal care, and pharmaceutical industries seeking superior texture, stability, and user experience in their topical formulations.

Application

• Topical Gels and Creams: Primary gelling agent for transparent hydro-alcoholic gels, antibiotic gels, and anti-inflammatory creams.
• Skincare Products: Stabilizer and thickener in facial cleansers, moisturizers, serums, and anti-aging formulations.
• Hair Care Formulations: Provides viscosity and suspension in styling gels, conditioners, and medicated scalp treatments.
• Pharmaceutical Ointments: Used as a base for dermatological preparations requiring a non-greasy, easily spreadable consistency.
• Oral Care Products: Thickening agent in toothpastes and oral gels to stabilize abrasive systems and active ingredients.
• Sunscreen Lotions: Helps suspend inorganic UV filters like zinc oxide and titanium dioxide, preventing settling.

Quality Control

Our Sodium Carbomer is manufactured under strict quality management systems. Each batch undergoes rigorous testing to ensure it meets the high-purity standards required for cosmetic and pharmaceutical applications. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing key parameters such as viscosity, pH, and residual solvents. We support compliance with global regulatory frameworks including REACH and can provide documentation for specific market needs.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect performance.
