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.
