Preservative does my formula needs?

Posted by Cdsgames on October 10, 2021 at 3:29 pm

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 phytate

The 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 Mark

we 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.

@Cdsgames

I mostly use Tetrasodium Glutamate Diacetate, often combined with Gluconolactone (and) Sodium Benzoate
