CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | NKRA |
|---|---|
| Color/Form | Monoclinic crystals from alcohol |
| Taste | Relative sweetness equal to sucrose |
| Boiling Point | 215-217 |
| Melting Point | 92-96 |
| Solubility | Very soluble in water, sparingly soluble in ethanol |
| Vapor Pressure | 0.00247 [mmHg] |
| Stability/Shelf Life | Xylitol is stable to heat but is marginally hygroscopic. Caramelization can occur only if it is heated for several minutes near ist boiling point. ... Milled and specialized granulated grades of xylitol have a tendency to cake and should therefore be used within 9 to 12 months. Aqueous xylitol solutions have been reported to be stable, even on prolonged heating and storage. |
| Decomposition | Since xylitol is not utilized by most microoragnisms, products made with xylitol are usually safe from fermentation and microbial spoilage. |
| pH | 5 to 7 (10 % w/v aqueous solution) |
| Collision Cross Section | 136.3 Ų [M+Na]+ [CCS Type: DT, Method: single field calibrated with Agilent tune mix (Agilent)] |
| Other Experimental Properties | Orthrhombic needles from tetrahydrofuran, prisms from ethanol; mp: 93-94.5 °C; density: 1.52. Solubility (g/100 g solution): absolute methanol 6.0; absolute ethanol 1.2; water 64.2 /Stable form/ |
| Chemical Classes | Other Classes -> Alcohols and Polyols, Other |

PRODUCT INTRODUCTION
description
Xylitol is a pentitol (five-carbon sugar alcohol) having meso-configuration, being derived from xylose by reduction of the carbonyl group. It has a role as a sweetening agent, an allergen, a hapten, a human metabolite, an algal metabolite, a Saccharomyces cerevisiae metabolite and a mouse metabolite.
