  • Sample turning white 1 month into stability testing

    Posted by Newtoformulating on May 4, 2022 at 3:37 pm

    Hello all! I just received a report from the lab that 1 month into stability testing my sample is turning white. Here is a snippet of what the lab had to say:

    “However, this is not being seen in the control product held at ambient so could be a function of the increased heat as well.”

    I think she may have a point with the heat but I also think that my preservative may be the culprit as well. Optiphen Plus. Any thoughts on the changes and is this change considered normal? Pic below
