Green mandarin oil is cold pressed from the peel of green (unripe) mandarins, the fruit of Citrus reticulata.
Mandarin Essential Oil Green CAS 8008-31-9
Mandarin Peel Oil is an orange-brown to dark yellowish-brown or olive-brown, occasionally lemon yellow (certain types of handpressed oil), mobile liquid of intensely sweet, not very fresh odor, occasionally with an amine-like, “fishy” topnote and usually with a rich neroli-like, floral undertone. Upon extreme dilution e.g. in ethyl alcohol, the oil shows a beautiful bluish fluorescence which fades significantly when the solution has aged. This effect, and the peculiar “perfume-like” odor type, is explained by the presence of about one percent of methyl-N-methyl-anthranilate in the oil.
