C E Ferulic Formula Stability and Patent Information

You are asking for scientific references and research on the properties of L-ascorbic acid, specifically when used in the C E Ferulic formula, for your presentation. The staff has provided a document ("SCIENCELP_KEYSTUDY_4.pdf") and an important note regarding the patent held by Skinceuticals Inc. for the stabilization technology using Vitamin E and Ferulic Acid. While you can create the formula, you cannot claim that this specific technique stabilizes the Vitamin C due to the patent.

My tools allow me to search for basic product information (like L-ascorbic acid, Vitamin E, Ferulic Acid) but I cannot access external scientific databases or the content of the attached PDF document to provide research papers directly.

Please review the document provided by the staff, as it is the intended reference. If you need basic information about the ingredients themselves, I can try to find that.
