Facial Mist Preservative Help
I am recreating a facial mist from a class project formulation and I only have Geogard ECT available even though the formulation uses Geogard Ultra.
Here’s my issue, although ECT is water soluble, it has a limit of 0.8% when used in ONLY water-based products, therefore requiring it to need a solubilizer for complete miscibility.
I used 1.0% Caprylyl Capryl Glucoside and now it feels “soapy” when applied. I’m thinking of reducing it but I’m not sure by how much. Any suggestions?
Water 69, rose water 25, cucumber extract 3.5, solubilizer 1, ECT 1, Aloe powder 200:1 0.2, potassium sorbete 0.2, sodium phytate 0.1

pH?
-
pH = 4.0

How much will your formula accommodate?
-
pH has to remain around 4.0 because the potassium sorbate loses some of it’s effectiveness around 4.5 and more if it gets to 5.0.
-
The difference is prob not significant, esp as you’re adding more via ECT.
-
I thought about that earlier. I’ll probably use Geogard 221 and disregard using a solubilizer completely. That way I’ll get rid of the “soapy” feel and only have the pH shift to contend with. I might purchase Ultra. Thanks for the responses!????
