Clarity and Properties of HPMC (5000cP, Food Grade) in Non-ionic Gels

Yes, Hydroxypropyl Methylcellulose (HPMC, 5000cP, 68C Gel, Food) creates a clear, non-ionic gel.

To achieve a clear and smooth texture, it must be dissolved using the correct method. If mixed improperly, it may result in clumps or a cloudy appearance.

Key Characteristics:

• Clarity: It provides a clear gel texture when fully hydrated and dissolved.
• Non-ionic: It is non-ionic, meaning it is stable in formulations containing electrolytes (salts) and can be used across a wide pH range (pH 3-11).
• Viscosity: This specific grade provides a viscosity of approximately 3,500-5,600 cPs at a 2% concentration in water.

Recommended Mixing Methods for Clarity:

1. Hot Water Dispersion Method:
   • Disperse the HPMC powder in hot water (80-90°C). At this stage, the liquid will look turbid (cloudy) because HPMC does not dissolve in hot water.
   • Once dispersed, add this mixture to cold water (or cool it down) while stirring continuously. As the temperature drops, the HPMC will hydrate and turn into a clear gel.
2. Glycerin/Glycol Dispersion Method:
   • Mix the HPMC powder in Glycerin or Propylene Glycol first until it is thoroughly dispersed.
   • Pour this mixture into cold water (ideally below 20°C) and blend. This will result in a clear gel texture.

Both the food-grade and cosmetic-grade versions of this product share these properties.
