Science & Chemistry Will isopropyl alcohol keep water from freezing? February 5, 2026 by Tanp | Leave a Comment Isopropyl alcohol can lower the freezing point of water, but it won’t entirely prevent it from freezing in extreme conditions. When mixed with water, it disrupts the hydrogen bonding, which can help keep the solution liquid at temperatures below water’s normal freezing point of 32°F (0°C). How Does Isopropyl Alcohol Affect Water’s Freezing Point? Isopropyl […] Read more »
