Preservative does my formula needs?
Hi,
I made a new formulation Pha 4% toner and I am thinking to use a ecocert preservative like leucidal sf complete.
Water
Glunocolactone 4%
Propanediol 3%
Solagum ax 2%
Preservative
Sodium phytateThe target ph is 3.9

Leucidal is not a very effective preservative.
-
Yes I am aware. Still the ph is low and we have chelator.
-
That means very little - it’s a poor preservative
-
Since you are already adding a heavy dose of Gluconolactone, why don’t you use Gluconolactone (and) Sodium Benzoate which is also EcoCert
-
Hi Markwe used Sodium Benzoate and Potasium Sorbate in the first formulation . I am wondering if adding just Sodium Benzoate will work (since we have gld already)
-
Mark a second question , if you dont mind . I seen in your posts that you like gld as a chelator , do we need sodium phytate at this ph ?
-
Sodium phytate is a good chelator. Stay with it.
-
I mostly use Tetrasodium Glutamate Diacetate, often combined with Gluconolactone (and) Sodium Benzoate
