No, water softener salt is not edible. While it's primarily sodium chloride (NaCl), like table salt, the processing and intended use make it unsuitable for consumption.
Why Water Softener Salt Isn't Safe to Eat
Several sources confirm that water softener salt is not for human or animal consumption. Even though it might be made from food-grade salt, the manufacturing process—including the pellet pressing—doesn't meet food safety standards. [Water softener salts are not intended for human or animal feeding](Reference Text). [Although water softener salt is safe to use in a water softener, it should not be used for food or animal consumption.](Diamond Crystal Salt Blog). [It's not food quality.](Reddit Post).
Furthermore, the risk isn't just about purity. The large, compacted crystals of water softener salt aren't easily dissolved or digested. [Therefore, direct application of pellets in food processing is not recommended.](Reddit Post).
While a tiny amount might not cause immediate harm, consuming it regularly isn't advisable. You really shouldn't eat water softener salt, though a tiny amount won't hurt you.. [DON'T DO IT! Seriously....the stuff is 100% poison.](Spartan's Will Forum). This statement is arguably strong but highlights the general consensus against eating it.
Key Differences Between Water Softener Salt and Table Salt
Although both contain sodium chloride, key differences exist:
- Purity and Processing: While the raw material might be food-grade salt, the processing methods for water softener salt don't adhere to food safety regulations.
- Crystal Size and Form: Water softener salt is typically in larger, compressed pellets, unlike fine table salt. This makes it unsuitable for direct consumption.
- Intended Use: Water softener salt is designed for water softening systems, not for culinary purposes.
