Nope, there is no chemical difference between glycerol, glycerin or glycerine. All 3 names refer to the same compound, propane-1,2,3-triol.

glycerols are the triol compound used for many purposes in pure or mixed form , but glycerine is the commercial name of glycerol, which is not pure ,which contain mostly 95% of glycerol , it can't be used when pure glycerol is required .

Glycerin and glycerol are both names for the same molecule. However, depending on where you are getting the glycerol from, it could be more or less pure.

As far as I know, glycerin and glycerol both refer to the same compound: propantriol.
