Carbomer 940 (Gel Maker/Thickener)

What is Carbomer 940?

Carbomer 940 is a high molecular weight crosslinked polymer of acrylic acid, commonly used in cosmetic and pharmaceutical formulations to adjust viscosity, stabilize emulsions, and suspend particles. When neutralized, it forms smooth, clear gels with excellent consistency and shelf stability.

Why Use Carbomer 940?

• Excellent Clarity: Produces crystal-clear gels when properly neutralized
• High Thickening Efficiency: Only small amounts required
• Emulsion Stabilizer: Supports O/W emulsions and reduces separation
• pH Responsive: Gels form on neutralization (ideal pH range: 5.5–7.5)
• Suspension Capabilities: Holds powders, pigments, or actives in place

Performance Highlights

• Provides luxurious texture and flow
• Compatible with alcohol, surfactants, and electrolytes (with caution)
• Enables stable, long-lasting formulations

Additional Application Examples:

• Water-based eye gels and primers
• Antioxidant or brightening gel serums
• Hair styling gels and pomades
• Shaving gels and cooling aftershave

Formulation Tip:

Disperse into deionized water under low-to-medium shear. Avoid clumping by sprinkling slowly. Once fully hydrated, neutralize with TEA (triethanolamine) or NaOH to pH 6–7 to activate gelling properties.

How to Use

Best added to the water phase at room temperature. Requires neutralization to reach full viscosity.

• Usage rate: 0.1% – 1%
• Neutralize to pH 6–7 for optimal gel structure
• Compatible with a wide variety of ingredients
