PNC 400

Pre-Neutralized Thickening Agent for Cosmetic Applications

Supplier: Evonik

Type: Technical Datasheet

PNC 400 (Sodium Carbomer) is a pre-neutralized, synthetic polymer utilized as a rheology modifier, thickener, suspending agent, and stabilizer in various cosmetic formulations. It offers superior handling, quick dispersion, and high viscosity properties, simplifying production processes by eliminating the neutralizing phase and ensuring a consistent pH throughout manufacturing.

Key Properties:

• Thickening Efficiency: Rapidly forms clear, viscous gels when introduced into water or water/alcohol blends (up to 70:30).
• Pre-Neutralized Formula: Eliminates the need for pre-dispersion or pH adjustment during formulation.
• High Clarity: Provides transparent, high-viscosity dispersions.
• Superior Stability: Maintains consistent pH and viscosity, simplifying formulation processes.
• Customizable Viscosity: Viscosity can be adjusted by altering polymer concentration or blending with acid polymers like Synthalen K for pH-sensitive formulations.

Claims:

• Simplifies production processes with superior handling and easy incorporation.
• Provides thickening, suspension, and stabilization in a wide range of formulations.
• Offers excellent viscosity control and clarity in finished products.

Applications:

• Cosmetic Products:
  • Emulsions (oil or water phase dispersion).
  • Clear gels for skincare or haircare products.
  • Water/alcohol-based systems (up to 70:30 blends).

Technical and Formulation Data:

• INCI Name: Sodium Carbomer
• CAS Number: 9003-04-7
• Appearance: Hygroscopic white powder
• Bulk Density: 0.3–0.45 g/cm³
• pH (0.5% dispersion): 6.0–7.5
• Viscosity (0.5% dispersion): Up to 55,000 mPa·s (Brookfield RV, 20 rpm, 25°C)
• Solubility: Easily disperses in water or water/alcohol blends, forming viscous gels.

Formulation Benefits:

• Ease of Use: Pre-neutralized formula eliminates the need for additional neutralizing agents.
• Flexible Viscosity Control: Viscosity can be adjusted by altering polymer concentration or using acid polymers like Synthalen K for pH-sensitive formulations.
• Stable Gels: UV-absorbers like Benzophenone-4 can be added to protect against viscosity loss under UV exposure.

Additional Considerations:

• Preservation: Gels prepared with PNC 400 do not prevent microorganism growth, so a preservative system is required.
• Environmental Stability: Ensure storage in dry conditions, with external moisture below 90%.

Safety and Toxicological Information:

• Acute Oral Toxicity (LD50): > 2000 mg/kg
• Skin and Eye Irritation: Non-irritant
• Skin Sensitization: Non-sensitizing
• Transport and Storage: Not classified as hazardous. Store in the original closed container under dry conditions.

Sustainability and Certifications:

• Eco-Friendly: Suitable for formulations requiring minimal environmental impact.
