Hi,
The difference between perfume and cologne exists in the concentration of the aromatic components, as perfume is usually 15 percent to 30 percent aromatics while cologne is only 3 percent to 10 percent aromatics. Understand the difference between perfume and cologne with helpful advice from a natural perfume producer in this free video on perfumes.
