D-Mannitol, marketed as Pearlitol SD200, is a naturally occurring sugar alcohol widely used as a pharmaceutical excipient, food additive, and nutraceutical ingredient. It is known for its cooling effect, low hygroscopicity, and excellent compressibility, making it ideal for direct compression in tablet formulations. With its USP/FCC grade, D-Mannitol is safe for oral and parenteral applications. It also serves as a bulking agent, sweetener, and stabilizer in foods, chewing gums, and medical formulations.
