Sodium Stearyl Fumarate Powder for Laboratory

Sodium stearyl fumarate powder is a crystalline substance utilized predominantly in the pharmaceutical industry as a tablet lubricant and disintegrant. It is derived from the reaction of stearyl alcohol (obtained from stearic acid) and fumaric acid, resulting in a fine, white to off-white powder with excellent flow properties. This compound serves a dual role: firstly, as a lubricant, it reduces friction between tablet granules and punches during compression, ensuring smooth tablet production and preventing sticking. Secondly, it functions as a disintegrant, promoting rapid tablet disintegration upon ingestion by absorbing water and swelling, thereby enhancing drug dissolution and bioavailability. Sodium stearyl fumarate is favored for its compatibility with active pharmaceutical ingredients (APIs) and its ability to maintain tablet integrity while facilitating quick and consistent disintegration in the gastrointestinal tract, crucial for effective drug delivery and absorption.
