S-S?tze Betriebsanweisung:

S24/25:Berührung mit den Augen und der Haut vermeiden.

Chemische Eigenschaften

clear colorless to straw yellow liquid

Occurrence

Reported found in grape, white bread, soy bean and licorice.

Verwenden

alpha-Angelicalactone acts as acancer chemopreventive agent. It is used in the synthesis of glutathione and the activity of glutathione-S-transferase and UDP-glucunonosyltransferase detoxification enzymes in esophagus, stomach, intestine, and liver. It is used in oral care formulations to round out mint notes and in coffee flavors.

Application

alpha-Angelica lactone finds occasional use in the reconstitution of essential oils. lts intensely sweet-herbaceous, almost tobacco-like odor makes this chemical interesting for application in new fragrance types. However, it would be wise to investigate its pharmacological and dermatological properties first.

synthetische

By dry distillation of levulinic acid

Allgemeine Beschreibung

α-Angelica lactone, a cyclic lactone that occurs naturally in tobacco, is generally used in tobacco flavoring.

Sicherheitsprofil

Moderately toxic by ingestion andintraperitoneal routes. When heated to decomposition itemits acrid smoke and irritating fumes.
