Formulating rosewater toner
I love the combination of rosewater or hydrosol, witch hazel and distilled water with nothing else added however, now I notice that I need a preservative. The potassium sorbate and citric acid lowers the ph of the toner to 3. Won’t this undue the good properties of the simple ingredients of the toner? I ordered Optiphen plus to keep the ph a bit higher but it seems that it may make the solution too clumpy any ideas? My main concern is what the ph is doing to the skin as a toner at ph 3.
