Using 3% HEC for Dry Brushing Toothpaste Gel Texture

Yes, you can use 3% of Hydroxyethyl Cellulose (HEC) (4500mPa.s) to create a gel texture suitable for a Dry Brushing Toothpaste Gel.

• Viscosity: HEC is a non-ionic thickener commonly used in toothpaste formulations because it is stable with electrolytes (like salts or abrasives often found in toothpaste). A 1% concentration provides a viscosity of 3,400-5,000 mPa·s. Using it at 3% will yield a very thick, high-viscosity gel, which is necessary to achieve the firm, non-dripping consistency required for a toothpaste gel.
• Compatibility: HEC is compatible with formulas having a pH between 3 and 9, which covers the typical pH range of toothpaste.

Preparation Tip:
To ensure proper dissolution and gel formation, remember that HEC dissolves best in water heated to approximately 70°C. You can either:

1. Warm the water to 70°C, then slowly sprinkle the HEC powder in while blending continuously until dissolved.
2. Disperse the HEC in cold water, then heat the mixture up to 70°C while continuing to blend. Once it reaches 70°C, turn off the heat and continue blending until cool.
