  Dissolving retinyl palmitate in oil

  Posted by Bluebird on February 25, 2025 at 3:05 am

  Supposedly it is possible, but I see it’s not working. I also read a very old thread on this forum saying that people are having difficulty dissolving RP.

  Anyone successfully dissolved RP in oil?

  Retinyl palmitate is oil soluble, so you should just be able to mix it in with no problem.

  But, I would assume if you are having trouble mixing it in to oil, then perhaps you have a dry vitamin A encapsulated onto starch or glucose rather than the oil form.

    You are right. I asked the manufacturer why this was not oil soluble and was rather water miscible, and asked whether there was any solubilizer in it. The answer you gave was exactly right, so it’s a pleasant surprise to come back here and read it, too.
