Alcohol is made from several sources. Although all forms of alcohol that intoxicate is forbidden in Islam but alcohol is also considered Najis (impure). Alcohol is treated as Najis substance in general. Those alcohols which are produced from dates and grapes are considered Haram and Najis. According to Imam Abu Hanifah and Hanafi scholars, alcohol made from sources other than dates and grapes is not considered Najis. Although the drinking of such alcohol remains forbidden due to the reason of intoxication.
Other Imams's opinion regarding the purity of alcohol regardless of its source is that it is Najis especially if the amount of it reaches the level of intoxication.
Alcohol used in modern perfumes is not made from grapes or dates. In most cases it is synthetic alcohol.
Therefore, based on the opinion of Hanafi scholars, use of perfumes that contain alcoholic content would be permissible.
There is another technical fact to be kept in mind during the discussion of alcoholic content in perfumes and that is when perfume is sprayed on clothes or body, the alcoholic content evaporates away immediately before it even reaches the clothes or body. Only the perfume content reaches the fabric or body.
Therefore, the use of modern perfumes would be deemed permissible regardless of the percentage of alcoholic content.
And Allah knows best.
