vikasintl asked:


We would like to know if there is any home testing to distinguish pure essential oil against diluted essential oil?

To make it clear…am not asking about differentiating pure essential oil against synthetic but am concerned about dilution.

Also we don’t want to spend money in lab testing like gas chromatography etc. so suggest if you know any home method to differentiate between these two?
