No. Beewax is a '45 carbon-long chain' mono-ester that is a waxy solid (C15H31COOC30H61 melting point about 60oC)

Glycerin is a 'three carbon-short chain' poly-alcohol viscous lquid (glycerol, C3H5(OH)3, propane-1,2,3-triol)

The common link is you can use beewax in soap by itself and by the process of "saponification" which breaks the ester down into its component long-chain carboxylic salt (aka Soap) and medium-chain alcohol (which is glycerin if you use beef tallow but something different with saponified beeswax).

If you look at saponification link, you'll see the general saponification reaction is R - CO - O - R' + NaOH --> R - CO - ONa (soap) + R' - OH (alcohol).

Normally when fatty acid esters (from beef fat aka tallow, etc.) are saponified, you get conventional soap and glycerin. When you saponify beeswax instead of tallow you get a soap and an alcohol that is different from glycerin but is an "analog" of it.

No, vaseline is petrolium jelly (an oil derived product), glycerine is derived from animals mainly, but is sometimes of vegetable origin.
