Perfume, Cologne Eau de Toilette what is the difference?? I am here to answer all some wait.. maybe a few of your questions. I am truly no expert. I know what I like and I like to smell good. FIRST, I like a very subtle scent. I don’t want to smell like I bathed in a bottle of perfume. I like subtle. So, on to the difference between perfume, cologne and eau de toilette. Basically, all fragrances are the same, but the name tells you the concentration of oil in alcohol and water. Fragrance is a big ole unisex term for any smelly substance that has fragrance oil diluted in alcohol and water. So, depending on the concentration, the result gets a different name. First, Eau Fraiche is a term I’ve never even heard of. Have you?? Maybe because this one only has one to three percent perfume oil. Meaning this one is only going to last for an hour…
