The typical denatured formula consists of 190-proof ethanol, 4% methanol and 1% other denaturants. This high concentration enables the denatured alcohol to dissolve the shellac flakes quickly and effectively. Isopropyl alcohol should not be substituted in this application for several reasons. Methanol toxicity is poisoning from methanol. Symptoms may include a decreased level of consciousness, poor coordination, vomiting, abdominal pain, and a specific smell on the breath. Decreased vision may start as early as twelve hours after exposure. Long-term outcomes may include blindness and kidney failure. Toxicity and death may occur even after drinking a small amount.
re。这么多高浓度酒精放家里也不安全啊
文科生，中学不学化学？到家了，嫌弃浓度高，不会加水？工业酒精，不能家用，到是真的。
很多囤货的买回去就放一边，谁会再去麻烦兑这兑那，再者说工业酒精不能作为医用酒精使用。
