often you hear of folks mislead to believe that glycerine is a preservative ... I think it's that the thick, heavy, syrupy consistency of glycerine that's coating the surfaces of whatever you're applying it to, is somewhat sealing it ... thus slowing the rate of decomposition due to lack of exposure to air/oxygen ... giving the false illusion of it being a preservative

agreed, no soapy taste associated with SB ... most likely confused with borax
in bait the amount of glycerine will vary, usually I am going for a particular consistency and moderate "freeze proofing" ... I do feel you can add too much, somewhat muting the odor/lift ... the same goes for over use of sodium benzoate ... these are just my thoughts based on my own observations and experiences
