Answers to Your Formulation Questions

Here are the answers to your questions regarding your ingredients and formulations:

Witch Hazel Freezing

Yes, your Witch Hazel is still usable even after freezing and developing a white precipitate. This is a normal occurrence when Witch Hazel is exposed to very cold temperatures. Once you leave it at room temperature, the precipitate should dissolve, and the liquid will return to its clear state, retaining its properties and effectiveness.

Mixing Half of the Vitamin C E Ferulic Kit

Yes, you can definitely mix only half of the Vitamin C E Ferulic kit. This is a good approach if you want to use the product more slowly and help maintain its freshness for a longer period.

Mixing Vitamin C Ester in Oil

Yes, you can mix Vitamin C Ester at an 8% concentration in oils like Rose Hip Oil or Jojoba Oil. Vitamin C Ester is oil-soluble and can be incorporated into oil-based formulations. To help it dissolve properly, you may need to use gentle heat, but ensure the temperature does not exceed 70°C to avoid degrading the ingredients. Heat just enough until the Vitamin C Ester is dissolved, then remove from heat and let it cool.
