1 - 6.5 moles ethoxylated
Glycerol is solely a core substance (initiator). However, it is
structurally related to propane-1,2-diol (both are C3) and there are
similarities in the metabolism of fatty acid esters of both substances
by the intestine. There are three free alcohol groups available for
formation of the NLP polyols, so the likelihood is that the side chains
will be mainly of one or two units, with some of three units. The
information on the toxicokinetics of glycerol, ethoxylated, >1 -<6.5 mol
(the NLP polyol), and higher oligomers/polymers generally, is based on
the information for glycerol, for triglycerides (fats) and for propane
1,2-diol and oligomers. Additional information is derived from studies
on the absorption of hydrocarbons. There is some further information in
Patty which has also been incorporated into this assessment. In
addition, some predictions can be made from the physicochemical and
toxicological information on the oligomers
