Description

Organic compound, polyhydric alcohol. Doesn't form water hydrates.

Where to buy

Can be bought in pharmacy (as sweetener named "Xylitol" in diabetics department - 103% 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.
It is not recommended to touch the crystal without varnish with bare hands because it can easily make crystal dull or even cracked.

Storage conditions

Store in its original form or under several layers of varnish at average humidity and room temperature. Do not store in matchboxes or cotton wool and do not heat.
