Question

I want to add the following ingredients to an aloe vera gel:

  • L-Ascorbic Acid (Vitamin C)
  • Alpha Arbutin
  • L-Glutathione Reduced

Can these ingredients be added? Are there any compatibility issues or considerations, especially regarding the gel's texture or stability?

Answer

Based on the staff's reply regarding adding ingredients to this aloe vera gel:

  • L-Ascorbic Acid (Vitamin C): The staff advises against adding L-Ascorbic Acid. This is because the gel already contains a form of Vitamin C (Ascorbyl Tetraisopalmitate), and adding L-Ascorbic Acid, which is acidic, could significantly lower the pH. A low pH (below 5.0) would weaken the gel structure, which is based on Carbomer.
  • Alpha Arbutin: The staff confirmed that Alpha Arbutin can be added to this gel.
  • L-Glutathione Reduced: The staff's reply did not provide information on whether L-Glutathione Reduced can be added to this specific gel.
