Cetalox is a base note in many perfumes BUT it\’s THE note in this scent which they say is not a perfume. All I know is that in my younger years I wore various scents regularly. Haven\’t done that in many years. UNTIL NOW. I received a sample of \’Not a Perfume\’ and thought \’what the heck\’. and put just a on the inside of my forearm. BOOM what a delightful cozy, clean, sexy scent on my skin. Love Love Love it!
