COR Passover guide 2019 says:Perfume, Cologne – make sure that it should not have Chametz-derived alcohol.
What if the label says only denatured alcohol ?
Some view that as a problem as it usually reversible. This is because the government requirement of “denatured alcohol” just requires that the reverse process be more expensive then just buying liquor.
Conclusion
If there is a chance that the alcohol comes from grain products and you follow the strict opinion of denatured alcohol then you should sell it with the rest of your chametz before Pasach.
But if anyone could give us information about the source of the alcohol in this product it would be helpful.
