Those leak detectors, as they are called, merely are an oily substance that
allows you to see where in the system that their is a leak.  Most likely, it
is somewhere where the hoses meet a condenser, compressor, evaporator, etc.,
or could be a leak in one of those components as well.  If it is a slow
leak, the leak detectors may take some time (days, weeks) to work out the
void.  Most likely could be the o-rings that are between the compressor and
the hoses.
