  • Can I use this to make perfume?

    SDA 40B is 200 proof ethyl alcohol denatured with t-butyl alcohol. It is used in perfumers, oils, soaps and other cosmetics. It is an excellent choice for perfumes because it is clear and evaporates quickly by the warmth of the sking releasing fragnaces uniformly.
