Ultrasound Gel Formulation

Creating an ultrasound gel is relatively simple, primarily involving a gelling agent in water. Here is a basic guideline:

Basic Formula Components:

• Water: The main component (usually purified or distilled water).
• Gelling Agent: To create the gel consistency. Options include:
  • AnyGel™: A water gelling agent that is easy to use by simply mixing with water until dissolved. It provides a non-greasy texture and is resistant to electrolytes. Use at a rate of 1-2.5%.
  • Carbomers (e.g., Carbomer U21, Carbomer Ultrez 30): These are also effective water gelling agents that create clear gels. They typically require neutralization with an alkaline substance (like Triethanolamine or AMP) to fully activate and form the gel. Use at a rate of 0.1-2%.
• Preservative: Essential to prevent microbial growth in the water-based gel. Choose a broad-spectrum preservative suitable for cosmetic or medical applications.

Simple Formulation Steps (using AnyGel™):

1. Measure the required amount of water.
2. Slowly add the AnyGel™ powder to the water while stirring or blending continuously to ensure even dispersion and prevent clumping.
3. Continue mixing until the AnyGel™ is completely dissolved and the gel texture is formed.
4. Add the preservative according to the supplier's recommended usage rate.
5. Mix thoroughly to ensure the preservative is evenly distributed.
6. Check the consistency and clarity. Adjust slightly if needed (e.g., add a tiny amount more gelling agent if too thin, ensuring it fully hydrates).

If using Carbomers, you would typically disperse the Carbomer in water, then add the neutralizer while mixing to thicken the solution into a gel, and finally add the preservative.

Always ensure all equipment is clean and sanitized to maintain the purity of the gel.
