Glycerin: the long-shelf-life compound most people overlook. Why stock it? Here’s how it’s surprisingly useful:
Doesn’t freeze, lasts indefinitely when stored properly
Moisture-retainer for homemade balms, lotions, and even soap to prevent cracking
Creates alcohol-free herbal tinctures
Acts as an antifreeze solution
Leather conditioner and rust prevention for tools
Mixed with baking soda, it becomes a DIY toothpaste
And yes, it’s reactive—can ignite with the right oxidizer, like potassium permanganate
