as salam alaikum
some Muslim scholars have considered alcohol to be najis resorting to some sort of qiyas, by saying that alcohol is the "spirit" of wine or other reasoning. However we do not find any direct evidence in the Qur'an and Sunnah to establish the najasah of non-beverage alcohol, and even alcohol in itself as some says, that is found in gel and wipes. Therefore it is permissible to use gel and wipes containing alcohol for hygienic purposes and hands won't get najis.
With prayers for your success.
