Glycerin and glycerol



I have recently found that I am severely allergic to glycerin. It seems most household products and foods contain glycerin. I see a lot of ingredients such as "glycerol" or "glycol", etc. Are these ingredients forms of glycerin and might they produce an allergic reaction as well?


Allergic reactions to glycerin is very controversial and uncommon. However, glycerol and glycerine are one and the same. Glycol is any number of alcohols that to my knowledge is not cross reactive (i.e. ethylene glycol, propylene glycol...)
