Issues with stability of an acidic solution
Hi to all !
I am having issues maintain stability for an acidic formula. I am suing the traditional hydroxucellulose and cetearyl alcohol ceteareth -2o . After formulating the formula looks fine- though after a week it starts to loose its viscosity and thickness.
I usually don’t heat up he cellulose to 75 degrees- is it criticall?
Should I increase the water phase acidity pre to additng the active acid ingredient?
PLEASE Help me out. I am lacking the knowledge to solve this by myself.
