คำถาม

I am formulating a cosmetic product using 15% ascorbic acid, 35% water, and Satin Cream Maker. Are my mixing steps correct? Are there any potential issues with this formulation, specifically regarding ingredient solubility or stability?

คำตอบ

Hello,

Regarding your revised formula and mixing steps, the staff has provided the following feedback:

  • The mixing steps you described are correct.
  • However, there are two potential issues with the formula:
    1. The amount of water (35%) might not be sufficient to fully dissolve 15% Ascorbic Acid. You will need to test this yourself. If it doesn't dissolve completely, you will see sedimentation.
    2. Satin Cream Maker might not be stable in the high acidity caused by 15% Ascorbic Acid. The staff suggests using an acid-resistant alternative or helper, such as AnyGel (Dehydroxanthan Gum), possibly in combination with Satin Cream Maker.

So, while the mixing method is correct, you should be aware of the potential dissolution issue with Vitamin C and the stability issue with Satin Cream Maker in this acidic formula.
