    Thanks to you both @Belassi and @MarkBroussard

    Yup. Vit C is a bit of the pain in the patootie.  But I’ll give it a whirl for myself in small, frequent batches and at the proper pH (as best as possible ) and see if my skin has anything positive to say about it ;).  Thanks again for all your help!

    @Belassi…  Righteo. I wondered if it was enough to change the color that most likely meant some amount of oxidation and therefore less effective at that point.  Thanks for your reply.  I figure I will stick to the pH the product recommends and just make separate lotions for different things.  And yes, I always make smaller batches and keep mostly refrigerated.

    Can’t always use the kitchen sink approach for everything even if it would be easier, I suppose, ha! ;) Thanks again.

    @ MarkBroussard…  Thank you. I was wondering about the sodium benzoate and do have gluconolactone by itself and I was going to test with just it to see if IT was bothering me at all.  Sorry to ask another question, but if the Gluconolactone should cause the pH to be too low, would the sodium citrate be an appropriate way to buffer?

    I don’t have those other preservatives yet, but can get some.  Right now, which I have not tried (it came as a sample), I have EPE 9010 Ethylhexylglycerin + Phenoxyethanol.  Do you know anything about that one?  If I should go with your other suggestion first or if you think this one would be safe enough to try since I already have it?

    Thank you again so much. I apologize for the additional questions.  Just don’t want to obliterate my skin if at all possible ;).  I so appreciate it.  You guys on this site are great!

    @thebrain…  Thank you.  I will try heating it, which I have not done before, as well as, order some sodium citrate to have on hand.  I may have to play with how much sodium citrate and try to find more online about buffering with it.  Thanks so much for your reply.  Good luck with your testing ;)
