In the name of Allāh, the Most Gracious, the Most Merciful
As-salāmu ‘alaykum wa-raḥmatullāhi wa-barakātuh
In principle, if a product contains alcohol which has been derived from dates and grapes then it is not permissible to use. The alcohol used in cosmetics is often synthetic and not khamr, hence, it would be suitable to use. If you are uncertain regarding the source of the alcohol, then it is better to exercise caution and purchase alcohol free products. 
And Allāh Ta‘ālā Knows Best
