Crospovidone XL is a high-quality disintegrant material which is widely used in tablet formulation. It is a cross-linked polyvinylpyrrolidone polymer that enhances tablet disintegration time and dissolution rate. Crospovidone XL is an ideal excipient for low-dose active ingredients that require rapid disintegration and dissolution in the stomach. It exhibits excellent flowability, high water absorption capacity, and compatibility with a wide range of active pharmaceutical ingredients. Crospovidone XL is a cost-effective and efficient ingredient that improves tablet quality and enhances the efficacy of drugs.
