Likely you are not getting an answer since these are fairly broad topics AND they are really Fundamentals you should be educating yourself on, For example, in this case;Tocopherol is not water soluble (although there are some forms altered to be so, but rarely used due to issues with PEG's. Solubulization is a huge topic which you will gain a great deal of benefit from studying formally. For example, the Gold standard is polysorbates. Does this meet your raw material standard? ()There are numerous discussions regarding Ferulic acid. When you read these, you will likely learn of the L'Oreal patent for using Ferulic acid to stabilize L-Ascorbic acid.Again, I am just suggesting that you delve deeper into these topics and read all you can.
