ABSTRACT:
A fluorescent leak detection composition is provided comprising water, a nonionic surfactant having an HLB value of about 12 to about 14 in an amount effective to produce stable bubbling of the composition for a time sufficient to enable detection of a leak in a container when the composition is applied to the surface thereof, about 0.025 to about 1.0 weight percent sodium fluorescein and a semisynthetic cellulose thickening agent in an amount effective to provide the composition with a viscosity of about 75 to about 125 cps at 20.degree. C. Preferably, an antifreeze agent is added in an amount effective to retard freezing of the composition for at least 5 minutes when the composition is applied to a cold surface, such as refrigeration pipes.
