Hi and thank you so much for responding, but further explaination would be much appreciated here .m  the surfactant part is clear here but what about the glycerites.. they contain water and glycerin and preserved from the supplier in their  sollow form . I just mix already preserved glycerites in propanediol, is that unsafe too.. thanks in advance and sorry if I am asking too much
