  Retinyl Palmitate stability

  Posted by LaurenB on November 18, 2016 at 4:50 am

  Hi all

  Looking for some info regarding Retinyl Palmitate stability in topical creams.  In a traditional emollient cream base (including Zinc) is there anything other than BHT & sunscreen ingredients needed to keep this ingredient both active and stable and have a decent shelf life?

  I’d like to include it in a cream base with a high % of vit E and between .5-.8%.  Why?… I used an ‘old timers’ salve many years ago that was a vitamin A based oily salve, it’s long since gone but I’ve never found a topical cream that comapred, so I’d like to have a go at it myself.

  Any suggestions would be great

  Thanks
