| | 3,3'-Thiodipropionic acid Usage And Synthesis |
| Chemical Properties | 3,3'-Thiodipropionic acid is WHITE FINE CRYSTALLINE POWDER | | Uses | Antioxidant in food packaging, soaps, plasticizers,
lubricants, fats, and oils. | | Uses | 3,3'-Thiodipropionic acid is used as an antioxidant for fats and other foodstuffs. | | Uses | 3,3'-Thiodipropionic acid is an antioxidant used to prevent fats and oils from going rancid. It has the same functionality as bha, bht, and propyl gallate. | | Definition | 3,3'-Thiodipropionic acid is a dicarboxylic acid. | | Hazard | Use in foods restricted to 0.02% of fat and
oil content, including essential oils. | | Flammability and Explosibility | Not classified | | Safety Profile | A poison by intraperitoneal andintravenous routes. Moderately toxic by ingestion. A skinand eye irritant. When heated to decomposition it emitstoxic fumes of SOx. | | Purification Methods | Crystallise the sulfide from water. [Beilstein 3 IV 735.] |
