    Glycerin and glycerol are chemically the same. They have the same chemical formula (CH2OH-CHOH-CH2OH). Glycerin is the common name of glycerol. The generic (proper name) is 1,2,3-trihydroxypropane.

    which is better for a higher heat reaction with potassium permanganate?

    I wonder if one could use them both to mix with flavored oils to vape?I know that one can use the vegetable glycerine.

    Glycerol can indeed be used as an eliquid for Vaping (E-cigs). The small electronic cigarette that RJ Reynolds has now produced has the word Glycerol i’m its ingredients (not Glycerin). I do have to say, I am still confused as to their different uses. If they Are the same thing, which this article Starts Out saying. Then why are they used for different things? At least at times.

    Thank you very much for your differentiation between glycerol and glycerin. I have a dermatological condition on my lips called exfoliative cheilitis. It is a scaly lip condition. There is a medical journal article called

    As per this review article (from the Glycerine Producers’ Association, authored in 1963, cited by 13 papers as per Google Scholar):


    From the introduction:

    “Glycerine (sometimes glycerin) is the term most often applied to the commercial product, which usually contains a small percentage of water. Glycerol (chemically, also 1,2,3-propanetriol) refers to the chemical compound and content in a formulation, specifically to the trihydric alcohol C3H5(OH)3.”

    So, this would be a good replacement for this entire article!

    I am a chemist and I don’t see the distinction this article is trying to make.

    From a chemist point of view, a glycerin is a type of molecule. For example Nitroglycerin is the nitrated form of glycerol.

    Glycerol to a chemist means “glycer” denotes that it is a glycerin, and “-ol” means that it is an alcohol.
    Glycerol is a glycerin with 3 alcoholic groups on it.

    When someone says “glycerin” and theyre not being specific as to what glycerin theyre talking about, it is understood to mean glycerol because that is the parent compound of all its derivatives.

    I could understand if industry made a distinction between pre processed glycerin (containing many glycerins) and post processed glycerol (containing specifically glycerol), but the real world difference is arbitrary.

    In short, I believe the distinction this article is drawing is just wrong.

      Hello Garrett:

      Thank you for clarifying, Mr. Scientist.

      No! Garrett is incorrect… Glycerin is the parent of Glycerol.

    Vegetable glycerin, propylene glycol, methylene glycol, ethylene glycol, glycerin of borax are same as “dihydroxypropane triol”

    If you put sucrose (table sugar) onto that above solution (means thickening), and you will get glycerin aka glycerol “trihydroxypropane triol” and glycerin fluid is same like silicone fluid

    They wont make you smart brother & sister, they just wanna make you confuse.. ^_*

    Thanks a lot for clarifying the doubts.

    There is zero difference between them. Glycerol, glycerine and glycerin are different names for the same thing.

    Source: me and many years in the glycerine industry.
