Based on the ingredients you are using, the issue you encountered is likely due to the incompatibility between the oil phase (Jojoba Oil, Vitamin E, Perfect-C, Pure-Bakuchiol) and the solution of Pure-Melatonin in Ethoxydiglycol. To create a homogeneous mixture without using heat, you will need to incorporate a solubilizer.

A solubilizer helps to bridge the oil and glycol phases, allowing them to mix and form a stable, uniform product. Based on the available ingredients, Ultra Solve™ is a suitable high-performance solubilizer that can help incorporate various oils and active ingredients into a formula.

Here is a suggested revised formula and mixing procedure:

Recommended Formula Adjustment

To achieve a homogeneous mixture, we will adjust the amount of Jojoba Oil slightly to incorporate a solubilizer.

• Pure-Melatonin™: 2 g
• Ethoxydiglycol: 2.6 g
• Vitamin E (dl-alpha tocopherol): 2 g
• Perfect-C™ (Ascorbyl Tetraisopalmitate): 3 g
• Pure-Bakuchiol™ (Natural Retinol, 99% Pure, USA): 1 g
• Ultra Solve™: 5 g (This is a suggested starting point, you may need to adjust based on desired clarity and stability)
• Jojoba Oil (to make up 100g total): 84.4 g

Total: 100 g

Revised Mixing Procedure (No Heat)

1. In a container, combine the Jojoba Oil, Vitamin E, Perfect-C™, and Pure-Bakuchiol™. Mix well until all oil-soluble ingredients are fully dissolved and combined (Oil Phase).
2. Add the Ultra Solve™ to the Oil Phase and mix thoroughly until it is completely incorporated.
3. In a separate container, mix the Pure-Melatonin™ with the Ethoxydiglycol until the powder is fully dissolved (Glycol Phase).
4. Slowly add the Glycol Phase to the Oil Phase + Ultra Solve™ mixture while stirring continuously. Continue stirring until the entire mixture is homogeneous and clear or uniformly dispersed.

This method uses Ultra Solve™ to help the oil phase and the glycol phase combine effectively without requiring heat, resulting in a stable mixture.
