| | Sodium dehydroacetate Usage And Synthesis |
| Description | Sodium dehydroacetate is the sodium salt of dehydroacetate. It is mainly used as a new generation food preservative and food additive, being used extensively in sauce, fruit, bread, cake, moon cake, margarine and beverage. Sodium dehydroacetate (DHA-S) has a wide spectrum of antimicrobial activity that accounts for its use in cosmetic products as a preservative and antimicrobial agent. It is effective in the treatment of both bacteria and fungi. It is also a kind of anticoagulant agent through depleting the blood level of vitamin K. | | Chemical Properties | White to yellowish powder | | Uses | Geogard(R) 111S preservative is based on dehydroacetic acid (DHA), the sodium salt form (NaDHA) and therefore are recognized by major cosmetic, toiletry and fragrance regulatory authorities worldwide for use in cosmetic and personal care products. | | Uses | Dehydroacetic acid sodium salt (DHS-Na) is used in the food industry as preservative for fruits, vegetables, fruit juice, honey, beer, milk, protein and fat products; in human and veterinary medicine as bactericide and fungicide. Product Data Sheet | | Uses | sodium dehydroacetate is a preservative against bacteria and fungi that is used at concentration levels of 1.0 percent or less. It is useful in combination with parabens. It may cause skin irritation. | | General Description | White powder. Used as a fungicide, plasticizer, toothpaste, preservative in food. | | Air & Water Reactions | Water soluble. | | Reactivity Profile | Sodium dehydroacetate reacts with acids. May react viogrously with strong oxidizing acids. | | Flammability and Explosibility | Not classified | | Safety Profile | Poison by intravenous route. Moderately toxic by ingestion. An experimental teratogen. Experimental reproductive effects. An eye irritant. Mutation data reported. When heated to decomposition it emits toxic fumes of Na2O | | References | Forester, John.
