Aroma
P-TOLYL ACETATE has pungent Lily-like odor, penetrating, floral,
Narcissus-like in high dilution, Horse-like,
urine-like undertones in higher concentration.
Pleasant notes are obtained normally at concentrations below 1% in the perfume creation,
but the material is still capable of totally
ruining a composition when the acetate is
applied in combination with certain fragrance
notes or single chemicals.
Finds some use in flavor compositions for
its intensely floral power, which can support
fruity notes, nut-like aromas, etc.
The concentration in the finished product is
usually about 0.5 to 10 ppm, but may reach
220 ppm in chewing gums.
