DI water? De-Ionized? The stuff marked "Not safe for human consumption: Lab Use Only" because of how dirty the ion exchange membranes get [among other things]

DI water? De-Ionized? The stuff marked "Not safe for human consumption: Lab Use Only" because of how dirty the ion exchange membranes get [among other things]?
Or were you trying to say 'distilled water'?
- otterley 9y agoOutside the US, distilled water is often called deionized water. Same thing, different name.
- logfromblammo 9y agoIt is not the same thing. Deionized water may contain neutral organic molecules, including viruses and bacteria, as it uses ion exchange resins pre-loaded with protons and hydroxides to remove all other anions and cations. Distilled water has been vaporized out of one container and recondensed into another, so contains nothing but water and molecules that form azeotropes with water. Distilled water is deionized, but deionized has not necessarily been distilled. In practice, however, both are overkill for baby formula.
- otterley 9y agoNobody's arguing that they're identical processes. My point is about the _labeling_ differences. Distilled water is often sold as deionized water in various parts of the world.
- logfromblammo 9y agoBut there is literally zero additional printing cost for using the word that precisely matches the purification process. They even have the same number of letters in English. Why would anybody do that?
