I am going to be mixing up my first transdermal following the recipie from this site= 40% ISOPROPYL ALCOHOL( ISO )
15% ISOPROPYL MYRISTRATE( IPM )
15% ISOPROPYL PALMITATE( IPP )
10% OLEIC ACID( OA )
10% PROPYLENE GLYCOL( PG )
The 15% IPM and 15% IPP can be combined and just use 30% IPM...
My ? is can I mix up a big batch of this and use it as I need it, or should I simply mix up what I will be using in the near future. I just am not sure if the ingredients will degrade in anyway by being mixed long term?
Thanks for any response.
