Toner/Essence Formulation

The formulation you provided is feasible. The staff's response confirms this and offers a helpful suggestion regarding the Licorice Extract.

Ingredient List and Recommended Adjustments

• Plankton Artemia Extract: 2%
• Safe-B3 (Vitamin B3, Niacinamide): 5%
• Panthenol (Vitamin B5): 1%
• Licorice Extract (Licochalcone A 1%, Water-Soluble): The staff recommends using this at 1% instead of 3%. While the manufacturer allows up to 3%, using 3% can result in a very dark color that may not be desirable for a cosmetic product. Reducing it to 1% will help maintain a lighter color while still providing benefits.
• GlucoBright (Acetyl Glucosamine): 3%
• MOIST24: 3%
• Butylene Glycol: 3%
• 1,2-Hexanediol (Super-Purified, Odorless): 3%
• Double Hyaluron Liquid: 0.1%
• Water: Remaining percentage

Mixing Instructions

All the ingredients in this formulation are water-soluble. Therefore, the mixing process is straightforward:

1. Measure the required amount of water (this will be the remaining percentage after adding all other ingredients).
2. Add all the other ingredients (Plankton Artemia Extract, Safe-B3, Panthenol, Licorice Extract, GlucoBright, MOIST24, Butylene Glycol, 1,2-Hexanediol, and Double Hyaluron Liquid) directly into the water.
3. Mix thoroughly until all ingredients are fully dissolved and the solution is uniform.

This simple method is possible because all components are compatible and dissolve in water.
