That all popular brands of perfume were graded and classified according the percentage of perfume oil mixed in with the alcohol base. And that words cologne and Eau de Toilette actually has different meaning and stands for specific measures like A cup and C cup. (Though not a HIC cup oops sorry this was meant to be a serious post). All this came about during a conversation I was having with a client and the word eau de cologne came up. And the amazing thing was none of us who were from around the table at that time new about it though we thought we were connoisseurs of perfume. So I just thought that I should share this with you just in case you were as ignorant about it as I was.
Splash Cologne: 1-3% oil.
Eau de Cologne: 2-5% oil. This is the basic combination of alcohol and oil. Usually priced under the top 3 and lasts at most a couple hours. Usually comes in a spray bottle
Eau de Toilette: 4-8% oil. This is the normal discount fragrance most people spend their money on. For everyday use and prices around ones budget. This typical combination lasts anywhere for 2-4 hours. .
Eau de Parfum: 8-15% oil. Eau de Parfum contains a little higher concentration than an Eau de Toilette.
Perfume: 15-30% oil. The most expensive, perfume usually lasts up to 6 hours. It is packaged in small bottles, and should be used sparingly.
Well now you know. Hope this was a little helpful.
