Scent of a man

I went to buy a deodorant today, and the shopkeeper showed me a cologne. I had no idea how to compare them... so I looked up on Google and here's what I found.

Cologne, deodorant and perfume are all alcoholic solutions of fragrance oils but differ in the percentage of fragrance oil and the grade of alcohol (percentage of alcohol to water).
The higher the concentration of fragrance oil, the longer the fragrance lasts.

	Cologne	Deodorant	Perfume
% of fragrance oil	3-6	6-15	15-25
% of grade alcohol	70	80	pure ethyl alcohol
Time span of fragrance	shortest	medium	longest
