Eye Gel Formulation for Dark Circles and Puffiness

Here is the information regarding your eye gel formulation:

1. Ingredient Compatibility and Additional Ingredients:

   • The ingredients you listed are generally compatible for use in a water-based gel formulation.
   • Your current selection effectively targets dark circles and puffiness with ingredients like REGU®-AGE and Safe-B3 (Niacinamide), and includes Apple Stem Cell for potential skin regeneration. Reservoir-Tech aids penetration, and AnyGel is the gelling agent.
   • The formulation aligns well with your stated goals. To enhance hydration or add soothing properties, you could consider adding a humectant like Glycerin (2-5%) or Panthenol (1-2%). However, the current list is a strong foundation for your objectives.

2. Correct Mixing Procedure:

   • A standard procedure for this type of gel would be:
     a. Disperse AnyGel™ in the water phase and allow it to hydrate fully to form the gel.
     b. Once the gel is uniform, add the water-soluble ingredients: Safe-B3™, REGU®-AGE, Apple Stem Cell Extract, and Reservoir-Tech. Mix until fully dissolved.
     c. Add Mild Preserved Eco™ and mix until evenly distributed.
     d. Check and adjust the pH if necessary.

3. Suitability of Mild Preserved Eco™ as a Preservative:

   • Mild Preserved Eco™ (Ethylhexylglycerin, Caprylyl Glycol) provides some antimicrobial activity and acts as a preservative booster. However, using it as the sole preservative at 1% may not provide sufficient broad-spectrum preservation for a water-based eye gel, which is susceptible to microbial growth and requires robust preservation due to the sensitivity of the eye area.
   • It is highly recommended to confirm with the supplier if 1% is sufficient as a standalone preservative for this application or if it should be used with a primary preservative. For eye products, using a proven, broad-spectrum preservative system suitable for the eye area is generally advised to ensure safety and efficacy.
