Sodium Stearyl Fumarate (CAS 4070-89-3), also known as SSF, is the sodium salt of a stearyl fumarate ester used as an inert, hydrophilic lubricant and pharmaceutical excipient in tablets and capsules, where it limits punch filming, aids disintegration, and supports flow and dosage uniformity in high-speed production. It offers superior purity levels compared to traditional lubricants, ensuring high formulation stability and compatibility with a wide range of active ingredients.

This hydrophilic lubricant exhibits excellent chemical resistance and effectively prevents sticking and picking during high-speed manufacturing. Its Pharmaceutical Grade quality is essential for modern solid dosage forms, providing better mechanical strength than metallic stearates.

SSF facilitates enhanced disintegration rates and is particularly effective for effervescent tablets and complex formulations. It serves as a vital functional excipient that optimizes flow properties while ensuring consistent dosage uniformity in high-output industrial processes.
