Hi kha. I just ordered some
Dipropylene glycol from you. I heard that it can make
Fragrance oils and
Essential Oil s last longer. I have just started making lotions and soap (Melt & Pour). Is it safe to add
Dipropylene glycol to recipes for lotions and soap. If so, how much should I add kha? Thank you for your help. I hope to be a longtime customer of MySkinRecipes. Methinee
