An older or alternative name for a boron-glycerol complex compound, still used in some pharmaceutical and cosmetic formulations.
From 'boro-' + 'glycerine' (the traditional spelling of glycerol, from Greek glykys). This represents an earlier nomenclature style before IUPAC standardization made chemical naming more systematic.
You'll find 'boroglycerine' in vintage pharmaceutical texts and old medicine cabinet labels because it was a popular antiseptic and preservative before we invented synthetic alternatives—it even appeared in some WWI-era medical supplies.
