Castoreum - I am one of those people who likes animalic notes in her perfume. Something about the warmth and organic nature of these aromas fascinates me. Jean Patou 1000, Guerlain Jicky, Paloma Picasso, vintage Cuir de Russie--all have strong animalic notes. They fascinate me. Their "dirtiness" holds my attention. One would, therefore, assume that I like civit and castoreum. To the contrary, I was surprised to find that can barely tolerate these substances on their own.
Castoreum Natural, profumo.it- smells rude and aggressive. It is leather with a bitter edginess. It has a fecal topnote and rubber undertone. My cat jumped up on my desk while I was writing about castoreum, and I held out my arm to her. She sniffed, looked at me with wide, alarmed eyes, and promptly jumped down and left the room. Do you understand what I mean by "aggressive?" Even she, with no vocabulary to describe it, decided that whatever had marked my arm with its scent was big, strong, and not to angered. This is a "masculine" note, no doubt about it. It claims territory.
Castoreum: i find this one fascinating. it is warm, velvety, honeyed leather with ambery notes. like you spent some days in a saddle, reminding me of days when i rode the one or other mean horse. why so many people find this smell repulsive - beats me. for me this is a great, great smell and i will definitely use it when we start to mix.
Castoreum, synthetic, Perfumers Apprentice – Registers as a “leather” note to me. Bitter, animalic, oily, a bit rubbery and smoky, slightly fecal. Yet, I find this note to be attractive. It smells like the pelt of a fur-bearing animal. If anyone has visited a furrier and stuck his or her face into the fresh coats, this is the aroma that exists underneath all the expense and supposed glamour—real animals. Now that I recognize it, I can say that my favorite perfume with castoreum is Paloma Picasso. (I always thought this was the “dirty little secret” of the department stores, possibly the most animalic of all mainstream perfumes these days, never failing to make some sales assistant wrinkle her nose in disgust.) I really like this note.
Castoreum: vanilla, leather, "band-aid", manure, antiseptic, must be the note that Dzing! emphasizes so well. I have smelled it in Shalimar and some other leather frags (can't remember now which ones). It is a bit headache-inducing.
