Formulasi & Suspensi

Suspensions are widely used in pharmaceuticals, food, cosmetics, and specialty chemicals. In pharmaceuticals, suspensions deliver poorly soluble drugs in liquid form, improving bioavailability and patient compliance. In food, suspensions appear in products like juices, sauces, and dairy drinks. In cosmetics, they are found in creams and lotions.
The challenge lies in maintaining stability. Suspensions tend to separate over time due to sedimentation, flocculation, or coalescence. Stability depends on particle size, surface charge, viscosity of the medium, and interactions between particles.
DataPhysics Instruments address these challenges with precision. The ZPA 20 (Zeta Potential Analyzer) measures particle surface charge, a key indicator of dispersion stability. High zeta potential values suggest strong repulsion between particles, preventing aggregation. The MultiScan system monitors suspensions over time, detecting early signs of instability such as creaming or sedimentation. The DCAT tensiometer measures interfacial tension, helping formulators understand how particles interact with the liquid medium.
In R&D, these tools allow scientists to optimize formulations by adjusting stabilizers, surfactants, and particle size. In production, they support quality assurance by providing reproducible, automated measurements that ensure batch-to-batch consistency.
Suspensions are not just mixtures—they are engineered systems requiring precise control of interfacial and colloidal properties. DataPhysics Instruments empower formulators to achieve this control, driving innovation and reliability across industries.
