Sodium Stearyl Fumarate CAS#4070-80-8
Sodium Stearyl Fumarate (SSF) is a high-purity, multi-functional excipient widely recognized in the global pharmaceutical industry. Primarily applied as an excellent tableting lubricant, it efficiently reduces interfacial friction between powder materials and mold walls during tablet pressing production. It effectively eliminates material adhesion, sticking and picking problems on tablet punches and dies, ensuring continuous, stable and high-efficiency tableting operation. Besides tablet manufacturing, SSF is also extensively used in capsule production and various oral solid dosage formulations to improve powder flowability, enhance mold filling uniformity and stabilize batch-to-batch product consistency. In addition to pharmaceutical applications, Sodium Stearyl Fumarate is also approved for food-grade usage. It serves as an ideal dough conditioner, texture improver and stabilizing agent in food processing, helping optimize product texture, improve processing tolerance and extend the overall stability of finished food products.

Sodium Stearyl Fumarate appears as a free‑flowing white powder and features very low practical water‑solubility. In the food processing field, it acts as a versatile dough conditioner and processing conditioning additive. It is commonly incorporated into yeast‑leavened baked goods to optimize dough performance, improve gluten structure and enhance the texture and machining property of finished bakery products. Besides bakery applications, this ingredient is adopted as a conditioning agent for dehydrated potato products, helping maintain stable physical characteristics during processing and long‑term storage. Furthermore, it can serve as an effective maturing and bleaching agent, bringing desirable colour‑adjusting and ripening‑promoting effects to relevant food formulations.
