Assuming your the same guy over at immort.org I guess you've read the reply to your same question over there. Maybe someone else might be interested.
Hello. I know 2 product that contain C vitamin , E vitamin and ferulic acid:
Pure C serum by Puredeming ( is a good product with ascorbic acid powder to mix with liquid that contains Tocopherol and Ferulic Acid).
House of Deming
LovelySkin Vitamin C&E+ Ferulic acid .

I thought Skinceuticals had a patent on CE Ferulic????
Of course this does not apply to DIY unless you try to sell it.
