SDS & MSDS for Distilled Water, Deionized Water & Reagent Water
CAS No. 7732-18-5 & A.C.S., ASTM D-1193-99 Type III
Water. Agua. Dihydrogen oxide. Good old H2O. A colorless, odorless, tasteless liquid, water covers more than 70% of our planet and is absolutely vital for all forms of life as we know it. In addition to its three naturally-occurring states (liquid water, ice, and steam), there are numerous man-made “types” of water, including sterile purified water, deionized water, distilled water and many others.
Though it seems like the most harmless liquid there is, water can be hazardous when combined with a large number of chemicals and compounds. Upon contact with these substances, water may react violently and/or exothermically and, in some instances, may yield toxic and/or flammable products.
To help you keep track of safety concerns and potential hazards associated with using water in its various forms, NuGenTec offers SDS and MSDS downloads for CAS No. 7732-18-5 (distilled water and deionized water) and A.C.S., ASTM D-1193-99 Type III (reagent water).

Distilled Water, Deionized Water & Reagent Water
Not all purified water is created equal. Distilled, deionized, and reagent water have all been purified to some degree. However, the level and method of purification can make a huge difference for research and laboratory purposes.
Distilled water has been boiled, then collected and re-condensed from steam. This process removes most impurities, including all solid contaminants, but other pollutants may vaporize along with the water and remain in the water after distillation.
Deionized water is filtered through an electrically charged resin to remove contaminants; however, this process does not remove molecular contaminants (sugar, for example) or uncharged organic particulate, such as bacteria.
Reagent water is “ultra purified” and must meet very specific requirements for purity and electrolytic conductivity. Reagent water may contain only very, very low levels (measured in parts per billion) of bacterial, organic, and other impurities.
