A dense, narcotic white-floral chemical with a strong narcissus and hyacinth character, edged with a fecal-animalic undertone typical of the para-cresyl esters. Sweeter, softer and less overtly barnyard than para-cresyl acetate, with a honeyed, slightly waxy floral warmth that lingers.AI · claude-opus-4-7
