Adding Apple Phloretin to Vitamin C Serum

Subject: Adding Apple Phloretin to Vitamin C + Ferulic Acid Serum

Based on the information provided, it is possible to add Apple Phloretin to your Vitamin C + Ferulic Acid serum formulation, similar to commercial products like Skinceuticals.

However, Apple Phloretin is oil-based, while the serum is primarily water-based. To incorporate it, you will need an emulsifier. The Vitamin C E Ferulic kit formulation already contains Laureth-23, which can act as an emulsifier.

Here's the suggested method:

1. Premix the Apple Phloretin with the Laureth-23 from the kit.
2. Gradually add this mixture to the water phase of your serum formulation while stirring.

Please note that the amount of Laureth-23 included in the standard Vitamin C E Ferulic kit might not be sufficient to fully emulsify the added Apple Phloretin and keep the final serum clear. Adding Apple Phloretin may result in a cloudy serum.

Based on estimation, adding 1% Apple Phloretin might require increasing the amount of Laureth-23 by approximately 3% to maintain clarity. You may need to experiment to find the optimal ratio of Laureth-23 for the amount of Apple Phloretin you wish to add to achieve the desired clarity.
