Description

Organic compound, four-carbon sugar alcohol. Doesn't form water hydrates.

Where to buy

Can be bought in supermarket (as sweetener named "Erythritol" or "Melon sugar", 60-70% of the sweetness of sucrose).

Notes

Dissolving is endothermic, solution cools much, so use hot water or using heat. Easily formes a supersaturated solution which can rapidly crystallize in all vessel volume while contacting with dust or touching the surface.
