For a chemistry project, I am doing an experiment to see whether the cryoprotective properties of glycerol onto water can be inhibited by adding a substance that will bond with glycerol to prevent it from bonding with water.  The problem is I cannot determine what that substance is.  Glycerol is C₃O₃H₈.  It is a polyol.  If any of you have any idea about what could bond with glycerol, but not bond with water, I encourage you to contact me.  I will be truly grateful. Thank you.

I've googled cryoprotective to find out that such substances help to prevent biological tissue from freezing damage. Presumably your experiment will involve some kind of organism? I think it would be useful to know a bit more about your experiment. It feels too obvious to suggest that fatty acids could be reacted with the glycerol, producing an insoluble fat. But this may interact with the lipid membrane of any organisms involved, prejudicing the validity of the experiment.
