Arctander says of it “occasionally used in perfume compositions, mainly to support ethereal, winey, brandy-like, fresh-citrusy and other light, non-floral top-notes. it has also been used to introduce an aged’ note to alcohol”. can react slowly over time with aldehydes present in the fragrance resulting in a loss of odour impact, this seems to be particularly an issue with triplal.
