There is no "cake powdered sugar". Powdered sugar is made from sugar, which is ground into a powdered form, with a minute amount of corn starch added to prevent it from "caking" or lumping.
Granulated sugar is just sugar. Powdered sugar has corn starch in it so that it will stay as a powder and not lump.
Powdered sugar is usually gluten-free, but it is important to always check the label. Some brands even label the package as gluten-free. Most commercial powdered sugars are blended with corn starch to keep them fluffy. Occasionally, some manufacturers have been known to use wheat products instead of corn starch, so ALWAYS check the label every time you buy! You can always make your own powdered sugar just by putting sugar in your blender or food processor until it's fluffy! Then you'll KNOW what's in it!
where can i buy some powdered water? read the directions
At Safeway
A sago pudding is a milk pudding made from sago, powdered starch obtained from palms and used as a food thickener.

You can, it's just not marked as such. Basic powdered or confectioner's sugar unless it is marked 10x is the same as 4x powdered sugar.
carnauba wax*, corn starch, hypromellose, powdered cellulose, triacetin
I don't think many recipes that need powdered sugar would work with a substitute, but you can make powdered sugar if you have a food processor. Put granulated sugar in the food processor and a little corn starch (about one teaspoon of corn starch to one cup of sugar). Run the food process for several minutes checking periodically to see if the sugar is fine enough. When it's powdery you can use it in your recipe.
Without adding a chemical, i can only think of lowering the temperature
