Deodorant Formulation with Anti-Sweat, SmellSorb, Vitamin B3, Essential Oil, and Water

Based on the sample formulation provided, here are the suggested percentages and considerations for the ingredients you listed:

• SmellSorb™: Use 2%. This is typically added to the oil phase of the formulation.
• Vitamin B3 (Niacinamide): Use 2%. This should be added to the water phase.
• Water: Start with 8% as a base. You will need to increase the amount of water in the formula to properly dissolve the Anti-Sweat ingredient. The exact amount of additional water needed will depend on the percentage of Anti-Sweat used.
• Anti-Sweat™: Add your desired percentage of Anti-Sweat to the water phase. Remember that adding Anti-Sweat requires increasing the water content in the formula. To maintain a total of 100%, you will need to reduce the percentage of other base ingredients, such as Cyclomethicone or Silicone Gel Base, by the amount of extra water added.
• Essential Oil: The percentage for essential oil depends on the desired fragrance strength, typically ranging from 0.1% to 1%. It can be added to the oil phase or at the very end of the formulation process.

Important Considerations:

• Adjusting Percentages: The percentages of Water, Anti-Sweat, Cyclomethicone, and Silicone Gel Base must be adjusted so that the total formula adds up to 100%.
• pH Adjustment: If you include Vitamin B3 in the water phase, the pH may increase. If the Anti-Sweat ingredient does not dissolve properly at this pH, you may need to adjust the pH down slightly by adding a small amount of a fruit acid (like citric acid).
• Preservative: The sample formulation provided does not include a preservative. It is crucial to add a suitable preservative to your formula to prevent microbial contamination and ensure product safety and shelf life.
