FVC-PAC6 (Viscocare-PAC6F)
FVC-PAC6 (Viscocare-PAC6F) – An Electrolyte-Resistant Thickening Polymer with Excellent Stability Across a Wide pH Range for Cosmetic Formulations
1. Introduction
✔ When developing cosmetic formulations, selecting the right thickening polymer is essential not only for achieving the desired viscosity but also for ensuring formulation stability, sensory performance, and compatibility with active ingredients. For formulations containing electrolytes, AHAs, Vitamin C, or other acidic actives, the polymer must be able to maintain viscosity and structural stability under various formulation conditions.
✔ FVC-PAC6 (Viscocare-PAC6F) is a synthetic polymer with the INCI Name: Polyacrylate Crosspolymer-6, designed to provide thickening and structural stabilization for a wide range of cosmetic formulations. It forms clear gels, performs effectively across a broad pH range, exhibits excellent electrolyte tolerance, and requires no pre-neutralization, helping simplify the manufacturing process.

2. Key Features of FVC-PAC6 (Viscocare-PAC6F)
✔ Excellent Electrolyte Tolerance
FVC-PAC6 exhibits outstanding electrolyte tolerance, allowing it to maintain viscosity even in formulations containing salts or high levels of electrolyte-rich active ingredients. This makes it an excellent choice for formulations with high active loading.
✔ Forms Clear Gels with Stability Across a Wide pH Range
FVC-PAC6 produces clear, stable gels and delivers effective thickening performance over a broad pH range of 2–10, making it suitable for various cosmetic formulations.
✔ No Pre-neutralization Required
FVC-PAC6 can be incorporated directly into formulations without a pre-neutralization step, simplifying the manufacturing process. It is suitable for both cold and hot processing.
✔ Improves the Stability of O/W Emulsions
In addition to its thickening function, FVC-PAC6 enhances the stability and structural integrity of oil-in-water (O/W) emulsions, contributing to the long-term stability of creams and lotions.
✔ Provides an Elegant Sensory Experience
FVC-PAC6 delivers excellent spreadability, a fast-absorbing skin feel, a moderate glossy finish, and low tackiness after application.
✔ Excellent Compatibility with Various Formulation Systems
• According to the technical data sheet, FVC-PAC6 demonstrates excellent compatibility with organic ingredients and remains stable under UV exposure, high-shear processing, and in formulations containing inorganic powders such as Titanium Dioxide (TiO₂) and Zinc Oxide (ZnO).
✔ Suitable for Formulations Containing Acidic Active Ingredients
• FVC-PAC6 maintains excellent thickening performance in formulations containing acidic actives such as AHAs and Vitamin C, while retaining viscosity even in the presence of electrolytes and salts.
3. Benefits, Performance Evaluation and Test Results
3.1. Thickening Performance at Different Concentrations
✔ Performance testing shows that the viscosity of FVC-PAC6 increases progressively as the concentration rises from 0.5% to 3.0%, demonstrating its flexibility in viscosity adjustment for different formulation requirements.
3.2. Viscosity Stability Across a Wide pH Range
✔ The viscosity of a 2% FVC-PAC6 solution was evaluated after adjusting the pH using lactic acid and 10% sodium hydroxide solution.
✔ The results demonstrate that FVC-PAC6 maintains high viscosity from pH 2 to pH 8, confirming its excellent stability over a broad pH range.
3.3. Electrolyte Resistance
✔ Electrolyte resistance was evaluated by adding sodium chloride (NaCl) to a 2.0% FVC-PAC6 solution and monitoring viscosity changes.
✔ The test results show that FVC-PAC6 maintains excellent viscosity in the presence of electrolytes, making it highly suitable for formulations containing salts and high concentrations of active ingredients.
4. Cosmetic Applications
✔ Thanks to its excellent thickening efficiency, structural stabilization, and broad formulation compatibility, FVC-PAC6 is recommended for applications including:
• Oil-in-Water (O/W) Emulsions
• Clear Aqueous Gels
• Emulsifier-Free Cream Gels
• Creams
• Lotions
• Gels and various other skincare formulations
