Formula Review and Pine Bark Extract Inquiry

Hello,

Regarding the spray formula you provided:

• Coffee Extract (3%) and Biotin Express (2%) are water-soluble.
• Sandalore (5%) is oil-soluble.
• Mild Preserved Eco (1%) has components with mixed solubility but can be dispersed/dissolved in water with blending.
• Ethyl Alcohol (30%) and Propylene Glycol/Butylene Glycol (59%) are water-soluble solvents.

Formula Suitability for a Non-Oily Spray

As written, this formula contains an oil-soluble ingredient (Sandalore) in a predominantly water/alcohol/glycol base. To achieve a clear, non-oily spray, you would need to add a suitable solubilizer to incorporate the Sandalore into the water phase. Without a solubilizer, the mixture will likely be cloudy or separate. The high percentage of alcohol and glycols will help with solubility to some extent, but a dedicated solubilizer is recommended for clarity and stability.

Mixing Procedure (with Solubilizer)

Assuming a suitable solubilizer is used:

1. Combine the oil-soluble ingredient (Sandalore) with the solubilizer. Mix until clear.
2. In a separate container, combine the water-soluble ingredients (Coffee Extract, Biotin Express, Propylene Glycol or Butylene Glycol) with water (the remaining percentage to make 100%). Mix until dissolved.
3. Add Mild Preserved Eco to the water phase and blend until clear.
4. Add Ethyl Alcohol to the water phase and mix.
5. Slowly add the oil/solubilizer mixture to the water/alcohol phase while stirring continuously until a clear solution is obtained.
