✅Answer: What is well-known is that: The alcohol used in industry has no difference in essence from medical or white alcohol, and both are ethyl alcohol or ethanol. However, for reasons such as taxing alcoholic beverages or preventing their misuse, the factories that produce alcohol add poisonous, bad-smelling (such as methanol or wood alcohol) and coloring agents (such as pyridine) to it, and that's why these alcohols can be deadly and blinding. It is also established that ethanol, as an intoxicating alcohol, is among the intoxicants, and the mere fact that it is mixed with other substances to prevent its misuse does not change its impurity. Please refer to the following narrations:

عَنْ أَبِی إِبْرَاهِیمَ قَالَ إِنَّ اللَّهَ عَزَّ وَ جَلَّ لَمْ یُحَرِّمِ الْخَمْرَ لِاسْمِهَا وَ لَکِنْ حَرَّمَهَا لِعَاقِبَتِهَا فَمَا فَعَلَ فِعْلَ الْخَمْرِ فَهُوَ خَمْرٌ

📚Al-Kafi vol. 6, p. 412

Imam al-Kazim, peace be upon him, said: Indeed, God, the Mighty and Exalted, did not forbid wine because of its name, but He forbade it because of its consequence and result; so anything that does the work of wine (causes intoxication and the loss of reason) is wine.

عَنْ عَمَّارٍ عَنْ أَبِی عَبْدِ اللَّهِ قَالَ لَا تُصَلِّ فِی بَیْتٍ فِیهِ خَمْرٌ وَ لَا مُسْکِرٌ لِأَنَّ الْمَلَائِکَةَ لَا تَدْخُلُهُ وَ لَا تُصَلِّ فِی ثَوْبٍ قَدْ أَصَابَهُ خَمْرٌ أَوْ مُسْکِرٌ حَتَّی یُغْسَلَ

📚Al-Tahdhib vol. 1, p. 278

Imam al-Sadiq, peace be upon him, said: Do not pray in a room where there is wine or any intoxicating drink, for the angels do not enter such a room, and do not pray in clothes that have been touched by wine or any other intoxicating drink until you wash it.

عَنْ یُونُسَ عَنْ بَعْضِ مَنْ رَوَاهُ عَنْ أَبِی عَبْدِ اللَّهِ قَالَ إِذَا أَصَابَ ثَوْبَکَ خَمْرٌ أَوْ نَبِیذٌ مُسْکِرٌ فَاغْسِلْهُ إِنْ عَرَفْتَ مَوْضِعَهُ وَ إِنْ لَمْ تَعْرِفْ مَوْضِعَهُ فَاغْسِلْهُ کُلَّهُ وَ إِنْ صَلَّیْتَ فِیهِ فَأَعِدْ صَلَاتَکَ

📚Al-Kafi vol. 3, p. 405

Imam al-Sadiq, peace be upon him, said: If wine or intoxicating nabidh touches your clothes, if you know its place, wash that place, and if you do not know its place, wash all the clothes, and if you have prayed in it, repeat your prayer.

عَنْ أَبِی بَصِیرٍ عَنْ أَبِی عَبْدِ اللَّهِ فِی حَدِیثِ النَّبِیذِ قَالَ مَا یَبُلُّ الْمِیلَ یُنَجِّسُ حُبّاً مِنْ مَاءٍ یَقُولُهَا ثَلَاثاً

📚Al-Kafi vol. 6, p. 413

Imam al-Sadiq, peace be upon him, said three times in the hadith about nabidh: That amount of nabidh that moistens a kohl stick makes a large jug of water ritually impure.

✅In other hadiths, the ritual impurity of wine, nabidh, and intoxicants has also been explicitly stated.

✅What is now established is that 'ethanol', which is a type of alcohol, has the property of causing 'intoxication'. According to the above narrations and other hadiths, it is an 'intoxicant' and 'wine', and consequently, it is considered 'ritually impure'. With this in mind, the mixing of ethanol with other non-intoxicating substances does not remove its impurity, and according to the narrations, drinking its diluted form also has the ruling of drinking an intoxicant and being ritually impure.

✅Note: The Ahl al-Bayt, peace be upon them, did not forbid 'alcohol' but rather forbade everything that is intoxicating and causes inebriation. Among the many types of alcohols, only those that, according to the above narrations, are 'intoxicating' in small or large quantities are forbidden and ritually impure.

✅Also, the mixing of ethanol with any other substance, including colors, medicinal syrups, perfumes, colognes, etc., which is common today, leads to that color, medicine, cologne, etc., becoming ritually impure.

✅It is obvious that a substance that is merely named alcohol but is in no way intoxicating, is not mixed with an intoxicating substance, and has no other religiously established reason for being ritually impure, does not fall under the above cases and is not ritually impure.
