works great for extending life of perfume samples and for diluting perfumes that are too strong [SEP] i get perfume samples from birchbox and this lets me make edt sprays that are not as overpowering and last longer by volume not by scent on arm i love it also works well with essential oils for my stinky homemade mosquito sprays i also have some perfumes that i love but which are too overpowering for my own sensitive nose so i like diluting them with this perfumers alcohol so they are more pleasant to wear
