eau de cologne
eau de toilette
eau de parfum

http://en.wikipedia.org/wiki/Perfume:
Perfume types reflect the concentration of aromatic compounds in a solvent, which in fine fragrance is typically ethanol or a mix of water and ethanol. Various sources differ considerably in the definitions of perfume types. The concentration by percent/volume of perfume oil is as follows:
*
Perfume extract (Extrait):
15-40% (IFRA: typical 20%) aromatic compounds
*
Eau de Parfum (EdP), Parfum de Toilette (PdT): 10-20% (typical ~15%) aromatic compounds. Sometimes listed as "eau de perfume" or "millésime".
*
Eau de Toilette (EdT): 5-15% (typical ~10%) aromatic compounds
*
Eau de Cologne (EdC): Chypre citrus type perfumes with
3-8% (typical ~5%) aromatic compounds
*
Splash and After shave: 1-3% aromatic compounds
