Sample turning white 1 month into stability testing
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
