Answers to Your Questions

Here are the answers to your questions based on the information available:

PE-1 Aqua in Vitamin C in Silicone Serum

Yes, PE-1 Aqua can likely dissolve in silicone-based serums. As a terpene penetration enhancer, it is expected to help ingredients like Vitamin C penetrate the skin better by opening skin channels, even if the Vitamin C is not fully dissolved in the serum base. The effect is thought to be more about preparing the skin for penetration rather than directly carrying the ingredient. It might be best suited for a night formula.

PE-1 Aqua with Flora Solve™ Clear in a Water Formula

Yes, you can use Flora Solve™ Clear to dissolve PE-1 Aqua in a water-based formula. However, terpenes are generally difficult to solubilize in water, similar to essential oils. You may need a relatively high concentration of Flora Solve™ Clear (potentially several times the amount of PE-1 Aqua) to achieve a clear solution. It is recommended to test the formula to see if the required amount of Flora Solve™ Clear affects the texture, such as making it sticky.

French Pine Bark Extract vs. Grape Seed Extract

These two extracts share the same primary active ingredient, Proanthocyanidins. However, they are extracted from different plants, resulting in different accompanying plant components. While the main benefits related to Proanthocyanidins will be similar, the overall effects or characteristics might not be identical due to these other compounds. They can be used interchangeably in terms of the main active component, but expect potential slight differences in overall performance.

Sunscreen Formulation 1 (Chemical/Hybrid)

The total percentage of the oil phase components in this formula (approximately 25.2%) is slightly above the maximum capacity of Satin Cream Maker™ (25%). To ensure proper emulsification, you would need to either reduce the total oil phase percentage or use an emulsifier capable of handling a higher oil load, such as Milk Lotion Maker, which can emulsify up to 40% oil phase.

Sunscreen Formulation 2 (Physical)

This formula can be mixed.

Sunscreen Formulation 3 (Revised Physical/Hybrid)

This revised formula can also be mixed.
