| Applications | Trehalose is used for the lyoprotection of therapeutic proteins, particularly for parenteral administration. Other pharmaceutically relevant applications include use as an excipient for diagnostic assay tablets; for stabilization during the freeze-thaw and lyophilization of liposomes; and for stabilization of blood cells, cosmetics, and monoclonal antibodies.Trehalose may also be used in formulations for topical application. |
| Safety | Trehalose is used in cosmetics, foods, and parenteral and nonparenteral pharmaceutical formulations. It is generally regarded as a relatively nontoxic and nonirritant material when used as an excipient.In the gut, trehalose is rapidly metabolized to glucose by the specific enzyme trehalase. A small minority of the population exhibits a primary (hereditary) or secondary (acquired) trehalase deficiency and thus may experience intestinal discomfort after ingestion of excessive amounts of trehalose owing to the osmotic activity of undigested trehalose in the gut. However, smaller amounts of trehalose are tolerated by such individuals without any symptoms. Trehalose is used as a sweetener and is reported to have substantially less cariogenic potential than sucrose.

| Incompatibilities | Trehalose is incompatible with strong oxidizing agents, especially in the presence of heat. |

| Stability and Storage Conditions | Trehalose is a relatively stable material. At 60℃ for 5 hours it loses not more than 1.5% w/w of water (the dihydrate water of crystallization is retained). Open stored powder may liquefy at high relative humidity (≥90%). Trehalose should be stored in a cool, dry place in a well-sealed container. |
| Source and Preparation | Trehalose is prepared from liquefied starch by a multistep enzymatic process.The commercial product is the dihydrate. |
