Ingredients for Laser/IPL Gel

To make a basic gel for laser or IPL machines, which acts as a coupling medium, you primarily need water, a gel-forming agent, and a preservative.

Here are some suitable ingredients:

• Gel-forming agent:

  • Carbomer U21 or Carbomer Ultrez 30: These are common choices for creating clear, water-based gels. They are powders that need to be dispersed in water and then neutralized (often with an alkali like AMP, though the descriptions mention they don't require pH adjustment for gel formation) to thicken. Use at a rate of 0.1-2%.
  • CarboQuick: This is a pre-dispersed Carbomer gel, making it easier to use as it mixes directly into water without needing to dissolve powder or adjust pH for gel formation. Use at a rate of 3-15% depending on desired viscosity.
  • AnyGel: Another water gelling agent that provides a non-greasy texture and good resistance to electrolytes. Use at a rate of 1-2.5%.

• Preservative:

  • Global Guard 221: A broad-spectrum, water-soluble preservative effective in pH 2-7. Use at a rate of 0.5-1.1%.
  • Mild Preserved COS: Another broad-spectrum, water-soluble preservative effective in pH 2-8 and odorless. Use at a rate of 0.75-1.5%.

Basic Formulation Concept:

1. Mix the chosen gel-forming agent into purified water according to its recommended usage rate and mixing instructions.
2. Once the gel is formed, add the chosen preservative at its recommended usage rate and mix thoroughly.

Always follow the specific mixing instructions and usage rates provided for each ingredient to achieve the desired consistency and ensure product stability and safety. It is also recommended to perform a challenge test if producing for sale.
