So, I'm in Canada which allows SA to be used at up to 2% in skincare.
I'm attempting to formulate an exfoliating mask (clay based O/W emulsion).
I have sodium citrate, citric acid, octyldodecanol and powdered SA. But what's the method?
Any suggestions would be really helpful since I have a feeling that throwing it into the water phase and forgetting about it is potentially disastrous.
