D-Galactitol | CAS No. 608-66-2

Q: What is D-Galactitol (CAS: 608-66-2)?

D-Galactitol, also known as galactitol, is a sugar alcohol (polyol) with the chemical formula C6H14O6. It is a white crystalline solid, highly soluble in water, and has a sweet taste similar to sucrose. As a reduced sugar derivative, it is commonly used as a low-calorie sweetener and exhibits hygroscopic properties. CAS 608-66-2 is the standardized identifier for this compound.

Q: What are the main uses of D-Galactitol (CAS: 608-66-2)?

D-Galactitol (CAS 608-66-2) is widely utilized in the food industry as a sweetener and texture modifier, in pharmaceuticals for sugar-free products, and in research for studying metabolic effects. It also serves as a humectant in cosmetics and is used in the production of certain chemicals. Its applications include sugar-free confections, dietary supplements, and as a component in eye drops and topical treatments.

Q: Is D-Galactitol (CAS: 608-66-2) safe?

D-Galactitol (CAS 608-66-2) is generally recognized as safe (GRAS) for food use by regulatory agencies like the FDA. However, excessive consumption may cause gastrointestinal discomfort due to its osmotic properties. Proper handling and adherence to safety standards are recommended, especially in industrial and research settings. It is non-toxic in typical exposure levels but should be used with caution as per established guidelines.

Q: How should D-Galactitol (CAS: 608-66-2) be stored?

D-Galactitol (CAS 608-66-2) should be stored in a cool, dry place, away from direct light, in airtight and moisture-proof containers. It is stable under normal storage conditions but may absorb moisture if exposed to humid environments. Maintaining controlled temperature and humidity ensures its shelf life and prevents degradation or clumping.
