Solubility and pH of Tomato Extract in Serum Formulation

Regarding your questions about Solanum Lycopersicum (Tomato Extract):

1. Solubility and pH: The solubility and recommended pH range for Tomato Extract depend heavily on the specific product and how it was processed. Different extracts can have different properties. It is best to check the technical specifications or ask the supplier/manufacturer directly for the most accurate information regarding solubility and stability in formulations, including the optimal pH range for a serum.
2. Using Propylene Glycol and Glycerin for dissolution: Propylene Glycol and Glycerin are typically used as humectants and solvents in water-based formulations. While Propylene Glycol can sometimes help solubilize certain substances, they are generally not effective for dissolving truly oil-soluble ingredients. To determine the appropriate solvent system, you first need to confirm the solubility of your specific Tomato Extract (e.g., is it water-soluble, oil-soluble, or dispersible?). If it is oil-soluble, you would typically need an oil-based solvent or an emulsifier to incorporate it into a serum.
3. Availability: We do not currently have Tomato Extract available for sale.
