D-Mannitol丨CAS 69-65-8

D-Mannitol丨69-65-8 is a naturally occurring sugar alcohol that is widely used in food, pharmaceuticals, and medical applications. It is a white, crystalline powder that is sweet-tasting but is not fully metabolized by the body, making it a popular alternative to sugar in certain products. D-mannitol is found in various fruits and vegetables, such as apples, mushrooms, and carrots, and is typically produced from natural sources like fructose for industrial use.

1.Pharmaceutical Applications D-Mannitol丨69-65-8 has several important uses in the pharmaceutical industry:
oOsmotic Diuretic: It is used as an osmotic diuretic in medical treatments. D-mannitol can be administered intravenously to reduce intracranial pressure in patients with head trauma, brain swelling, or intraocular pressure in patients with glaucoma. It works by increasing the osmolarity of blood, which draws fluid from tissues and reduces swelling.
oRenal Protection: It is also used to promote urine production in cases of acute renal failure or to prevent kidney damage caused by certain medications or conditions, like contrast-induced nephropathy.
oDrug Formulation: D-Mannitol丨69-65-8 is often used as an excipient in drug formulations, especially for creating tablets or capsules. It helps to provide bulk to solid medications and can also act as a bulking agent in inhaled drug formulations.
oInhalation Formulations: D-mannitol is sometimes used in inhaled formulations, particularly in dry powder inhalers, for patients with conditions like cystic fibrosis. The osmotic properties of mannitol can help mobilize mucus in the lungs and improve lung function.
2.Food and Beverage Industry
oSugar Substitute: D-mannitol is used as a sugar substitute in sugar-free foods and beverages, including gum, candies, and baked goods. It provides sweetness but does not significantly affect blood sugar levels, making it suitable for individuals with diabetes or those following low-calorie or low-sugar diets.
oLow-Calorie Sweetener: Due to its low glycemic index and low caloric content, D-mannitol is commonly included in low-calorie and diet foods as a sweetener. It is also less likely to cause tooth decay compared to traditional sugars, making it beneficial for oral health.
oHumectant: D-Mannitol丨69-65-8 is used in food processing as a humectant (moisture-retaining agent). It helps maintain moisture in products like candies, baked goods, and dried fruits, thereby improving texture and shelf life.
3.Medical and Diagnostic Uses
oDiagnostic Imaging: D-mannitol can be used in diagnostic imaging techniques like MRI or CT scans. It helps to improve image quality by acting as a contrast agent that enhances the visibility of certain areas, particularly in the brain or kidneys.
oDiagnostic Tests for Pulmonary Function: Mannitol is used in pulmonary function tests to diagnose and assess conditions such as asthma. Inhalation of mannitol causes a transient narrowing of the airways in susceptible individuals, which can be measured to help evaluate airway hyperresponsiveness.
4.Cosmetics and Skincare D-Mannitol丨69-65-8 is used in some cosmetic and skincare products due to its moisturizing and skin-soothing properties. As a humectant, it helps retain moisture in the skin, keeping it hydrated and soft. It is often included in lotions, creams, and hair care products to improve texture and promote hydration.
5.Industrial Applications
oPharmaceutical Excipient: In the manufacturing of tablets and capsules, D-mannitol is used as a bulking agent, making it easier to formulate consistent and stable products. It also helps control the release of active ingredients in sustained-release formulations.
oCryoprotectant: D-mannitol is used in the preservation of biological materials, such as cells, proteins, and enzymes, during freezing. It helps prevent damage caused by ice crystal formation, making it useful in the biotechnology and cryobiology industries.

1.Sugar-Free Alternative for Diabetes D-Mannitol丨69-65-8 has a low glycemic index, which means it has minimal impact on blood glucose levels. This makes it a popular sugar substitute for people with diabetes or those trying to manage their blood sugar levels. Unlike regular sugar, D-mannitol does not cause a sharp rise in blood glucose, making it a suitable option in sugar-free and diabetic-friendly foods and beverages.
2.Promotes Diuresis As an osmotic diuretic, D-mannitol helps promote urine production, making it valuable in conditions where the removal of excess fluid from the body is necessary, such as in cases of kidney failure, glaucoma, or brain swelling. By pulling water from tissues into the bloodstream, it helps reduce edema (swelling) and lowers pressure in the eyes and brain.
3.Supports Kidney Function D-mannitol is used in medical treatments to protect the kidneys from damage, particularly during high-risk procedures like contrast imaging or after certain types of surgery. It helps maintain proper fluid balance and promotes urine output, reducing the risk of kidney damage in critical situations.
4.Supports Respiratory Health Inhalation of D-mannitol has been shown to improve lung function in patients with cystic fibrosis, a genetic condition that causes mucus buildup in the lungs. D-mannitol works by drawing water into the airways, which helps to thin mucus, making it easier to clear and improving breathing function.
5.Oral Health Benefits D-Mannitol丨69-65-8, when used in sugar-free gum or candy, may help maintain oral health by reducing the risk of cavities. Since it is not fermented by the bacteria in the mouth, it does not contribute to tooth decay, unlike traditional sugars.

D-Mannitol is a versatile compound with a wide range of applications in the food, pharmaceutical, and medical industries. Its low glycemic index makes it a useful sugar substitute for individuals with diabetes, and its ability to draw water makes it valuable as an osmotic diuretic, in renal protection, and for respiratory health. Additionally, D-mannitol is used as a humectant in cosmetics, a cryoprotectant in biological applications, and as a bulking agent in pharmaceuticals. While generally safe, excessive consumption of mannitol can cause gastrointestinal issues, and it should be used with care in medical treatments.
