The code of canon law explains that "true, clean, and natural water" is necessary for baptism (canon 849). Liquids can be assessed in three categories: Those that are certainly valid, those that are doubtfully valid, and those that are certainly invalid.Certainly valid liquids include water as found in rivers, oceans, lakes, hot springs, melted ice or snow, mineral water, dew, slightly muddy water (as long as the water predominates), and slightly brackish water.
Doubtfully valid liquids are those that are a mixture of water and some other substance, such as beer, soda, light tea, thin soup or broth, and artificially scented water such as rose water.The last category is of liquids which are certainly invalid. It includes oil, urine, grease, phlegm, shoe polish, and milk.
The rule of thumb is that, in emergency situations, you should always try to baptize with certainly valid liquids, beginning with plain, clean water. If plain water isn't available, baptize with a doubtfully valid liquid using the formula, "If this water is valid, I baptize you in the name of the Father . . ." If the danger of death passes, the person should later be conditionally baptized with certainly valid water. Never attempt to baptize anyone with a certainly invalid liquid.
