Sachets offer a compelling combination of convenience, precise dosing and formulation flexibility.
Yet their apparent simplicity conceals a demanding technical challenge: creating a powder or granulate that processes reliably, remains stable and is pleasant to take.
A format designed around the patient
Swallowing difficulties, dosage accuracy and convenience can all affect how easily people incorporate a product into their routines.
Sachets meet modern consumer expectations by delivering precise dosing in a compact, convenient and on-the-go format.
Depending on the formulation, the contents can be taken directly or dissolved in water.
This makes sachets suitable for a broad range of users, including those who may find conventional tablets difficult to swallow.
Taste and mouthfeel remain critical. A convenient format only delivers its full value when the formulation itself provides a good experience.
Reliable filling starts with the right particles
From a manufacturing perspective, powders used in sachets must flow consistently through filling equipment.
Irregular flow, dust formation or segregation can disrupt processing and compromise dosing precision.
Particle characteristics therefore deserve careful attention. Agglomerated particles with a low fines content can support cleaner processing, accurate filling and reliable sealing.
Superior flowability can also promote production efficiency at higher operating speeds. The choice of excipient plays an important role here.
A plant-based excipient from BENEO — galenIQ™ — combines outstanding flowability, flexible design, low fines content (clean processing with low dust) and a sweet taste.
These characteristics enable formulators to develop robust sachet products while supporting efficient production and packaging.
Performance continues after packaging
A successful sachet formulation must remain stable throughout its intended shelf-life and perform consistently at the time of use.
For patients, the benefits extend to this moment of use.
A pleasant, sweet taste can improve palatability, whereas the easy-to-swallow, premeasured format supports accurate dosing.
Compact and convenient, sachets can also offer flexible intake with or without water, making them well-suited to use on the go.
Connecting formulation and format
Sachets can accommodate a wide variety of pharmaceutical and nutraceutical concepts, from direct-to-mouth products to formulations containing vitamins or probiotics.
Their potential, however, depends on aligning patient needs with the realities of manufacturing.
By considering flow, stability, solubility and sensory performance from the outset, developers can create sachet products that are not only convenient to carry but also reliable to manufacture and easier to use.
