Fact: Polyglycol compressor fluids are generally blended with one of two types of Esters: Polyolesters or Diesters
Small signals due to diester

2005) showed that the usual mixtures of monoester preen waxes of Calidris canutus (Linnaeus 1758) at the beginning of incubation are replaced by mixtures of less volatile diester
waxes, probably more difficult to smear onto the plumage; they set forth the hypothesis that diester
waxes reduce bird smell and thereby reduce predation risk.
