How can tablet production be optimised? The use of Sorbitol T in direct compression
In modern pharmaceutical and nutraceutical manufacturing, processing time and formulation stability are key factors affecting profitability. The traditional wet granulation method results in high energy costs and prolongs the production cycle. The solution to these challenges is direct compression, which, however, requires carriers with a specific structure. Spray-dried Sorbitol T is a functional hexahydroxy alcohol, developed specifically for direct compression. Thanks to its controlled particle structure, it enables stable compression parameters to be achieved and reduces or eliminates stages in tablet mass preparation, such as granulation or drying.
Granulation efficiency vs. direct tableting – a technical analysis
Switching to direct tableting using pharmaceutical-grade sorbitol E420 with a purity of ≥98% enables higher tablet hardness to be achieved at significantly lower compression forces. In practice, this translates into tangible operational benefits:
reduced wear and tear on machinery – lower compression forces extend the service life of punches and dies,
improved aesthetics – sorbitol T reduces brittleness and dusting, ensuring excellent uniformity and finish of the finished tablets,
parameter stability – the specific particle structure obtained through a controlled spray-drying process guarantees the reproducibility of each batch, thereby eliminating the risk of unplanned downtime.
Physicochemical stability and protection of active ingredients
Sorbitol T is characterised by high thermal and chemical stability. Unlike conventional sugars, this polyol does not undergo the Maillard reaction (browning), which is crucial for maintaining the snow-white colour of tablets. Its moderate hygroscopicity promotes the long-term stability of formulations, reducing sensitivity to moisture.
As a carrier, Sorbitol T supports the uniform binding of active pharmaceutical ingredients (APIs), colourants and flavourings. As it remains stable across a wide pH range and is chemically inert, it does not interact with sensitive ingredients, allowing for the creation of safe fast-release products with a predictable release profile.
Bio-based purity and regulatory safety (Ph. Eur./USP-NF)
For quality and procurement departments, the traceability of raw materials is of paramount importance. Sorbitol T is produced through the catalytic hydrogenation of plant-based glucose, which makes it bio-based. It is completely free from GMOs, preservatives and solvents, which facilitates the development of clean-label products.
Compliance with the stringent pharmacopoeial requirements of Ph. Eur. and USP-NF (E/INS 420 and GRAS status) significantly shortens the supplier verification process. By choosing MEDICOS as your sorbitol distributor in Poland, which provides full access to documentation (CoA, SDS), you can be confident that the raw material will pass audits in pharmaceutical, food and dental manufacturing without any issues.
