GLYCERIN USP, PH.EUR.
Glycerin
GLYCERIN USP, PH.EUR. is actually obtained from two types of industries:
– Chemical plants producing oil fatty acids, where the basic process is the splitting of the oil to obtain fatty acid and glycerine.
– Plants producing biodiesel, where the basic process is the esterification of oil to obtain oil ester and glycerine.
Glycerine thus obtained must be concentrated and distilled in a vacuum to obtain the desired glycerol concentration.
