Abstract
The embodiments of the present invention disclose a composition for the colorimetric detection of water in hydrocarbon fuels and a process for the preparation thereof. The embodiments of the present invention relate to an improved method for determining the presence or absence of water in non-polar organic fluids such as petroleum oil or hydrocarbon oils by using an indicator system containing a water insoluble wetting agent and a water soluble dye which can be performed rapidly without costly instrumentation and tedious, time consuming analytical methods.
