When you shop for ink tattoo temporary, the first thing you should look for are companies that use only ingredients approved by the FDA. To date, the FDA does not regulate tattoo ink temporary, to be wary of any company say their ink is actually approved by the FDA.
The next point to look out for the advertising business focused on the ink. Do not you want to change the chemistry of inks that you sprayed, reducing their own. Buy inks that are ready to spray. Sometimes it is also slightly reduce the airbrush inks prepared properly, but small changes is much more logical than having to reduce the inks in concentrated form.
