Shave Gel
Hello,
I’m making a prototype shave gel (texture of a body wash to be dispensed from a pump) similar to texture of Aesop Shave Serum. I have sodium stearate in this formula because of the dense creamy foam/lather it really produces. Sodium Stearate can dissolve in propandiol or hot water phase at 80c.
pH is 9 but I need to reduce it to be 5.5 to accommodate preservative.I’m experimenting with propandiol instead of glycerin, this go around.
What can I use to reduce ph9 to 5?
Citric acid 1% broke the gel.
Sodium citrate raises ph?
Any assistance would be greatly appreciated. Thank you.
