Formula for Energizing Oral Spray -- 2

I am creating a mouth spray that does more than freshen breath—it must actively support oral health while giving users an immediate sense of focus and energy. The core actives I want incorporated are Caffeine (as listed in the options) and green tea extracts; no other stimulants are planned at this stage.

Your task is to translate this concept into a stable, consumer-ready formulation. The spray should be safe for daily use in the mouth, deliver a pleasant taste, and remain clear with no sediment or separation through its shelf life. Please factor in pH balance, preservative needs, solubility of actives, and compatibility with common spray pump components.

Deliverables
• Bench-scale formulation with exact percentages for each ingredient, including flavor, sweetener, and preservative system
• Prototype batch instructions (equipment, temperatures, mixing times) suitable for small pilots
• Basic stability and microbiological test protocol outlining how to confirm product integrity over time
• Regulatory and safety guidance covering GRAS status or cosmetic/OTC positioning in the U.S. market
• Suggested analytical methods (e.g., HPLC for caffeine, microbial limits testing) to validate each batch

The project is complete once the formulation passes preliminary stability in your lab or a trusted partner facility and all documentation is supplied in editable form. I’m ready to begin as soon as we agree on milestones and timelines.
