Binder in some types of solid rocket fuel

Solvents

In medicine and cosmetics (base for ointments)

Cryoprotectant, the basis of plant growth regulators

Strong osmotic, used to simulate drought in vegetation experiments.

The basis for special fluids in brake systems, due to the combination of a high boiling point, lubricating property, minimal corrosion activity and stable low viscosity over a wide temperature range, including severe frosts.

Registered as a food supplement E1521.

It is used in modeling underwater eruptions: when this substance is poured out into a cold solution of sucrose, it takes the same forms as lava solidifying under water. Due to this, it is possible (by introducing appropriate amendments) to determine the conditions under which various types of solidified lava appear

It is used to create some biopharmaceutical preparations in which molecules of active biopolymers (proteins, enzymes) are covalently linked to oligomeric units of polyethylene glycol. This modification by covalent addition of polyethylene glycol is called pegylation.
