What is the rulling about alcohol denat in the fragnance (perfume),i haven't any scholar in my locality (france paris).

wa ʿalaikum al-salām wa raḥmatullāhi wa barakātuh

Alcohol denat is ethanol that has been denatured, in other words, they've added a solvent to it to make it unfit for human consumption. This denaturing process does not change the fact that it is still ethanol, a liquid intoxicant. That said, according to the Shafiʿi madhhab, alcohol denat is an impure substance just like wine.

Allah knows best.
