Ruling on selling cologne and perfuming oneself with it

If the alcohol content of cologne is at such a level that one
could become intoxicated by drinking a lot of it, it is haraam to keep it,
whether a little of itor a lot, and it must be poured away and destroyed
because it is khamr (an intoxicant). It was proven that the Prophet
(peace and blessings of Allaah be upon him) commanded the Muslims to pour
away whatever wine they had when the following verse was revealed
(interpretation of the meaning): 

“O you who believe!
Intoxicants (all kinds of alcoholic drinks), and gambling, and
Al‑Ansaab,[stone altars for sacrifice to idols, jinn, etc] and Al‑Azlaam
(arrows for seeking luck or decision) are an abomination of Shaytaan’s
(Satan’s) handiwork. So avoid (strictly all) that (abomination) in order
that you may be successful.

91. Shaytaan (Satan) wants only to excite enmity and
hatred between you with intoxicants (alcoholic drinks) and gambling, and
hinder you from the remembrance of Allaah and from As‑Salaah (the prayer).
So, will you not then abstain?”

[al-Maa’idah 5:90-91]

And it was proven that the Prophet (peace and blessings
of Allaah be upon him) said: “Whatever intoxicates in large amounts, a
little of it is haraam.” Narrated by al-Tirmidhi, 1865; Abu Dawood, 3681;
classed as saheeh by al-Albaani in Saheeh Abi Dawood. 

Based on this, it is haraam to drink it, perfume oneself with
it or purify oneself with it. But if the alcohol content is not at such a
level that drinking a lot of it would cause intoxication, then it is
permissible to buy it and keep it and use it as a perfume or for purifying
oneself, because the basic principle is that things are permissible unless
there is proof to the contrary.
