Together with Prof. Steven Abbott and Dr. Charles Hansen, VLCI promotes HSP for a wide range of applications.
Solubility of a product is represented as a sphere and characterized by three Hansen Solubility Parameters (HSP):
The HSP theory is based on the “like seeks like” principle, with likeness measured by the HSP distance metric. The critical conditions for solubility are found within a spherical region of HSP space, around the centre. Therefore, inclusions in the sphere, or overlapping spheres, predict solubility or compatibility.
HSP determination is a powerful and practical way to understand, predict and improve:
HSPs allow strong predictions for smart and efficient ingredient matching, and is applicable to many types of ingredients: polymers, oils, pigments, solvents, additives…
VLCI is a certified research centre for determinations of HSP and implementations thereof. The solubility (or dispersibility) of a product is assessed within a standardized set of solvents with known HSPs, spread over the 3-dimensional HSP space. Solvents and products are automatically dispensed via the gravimetric dispensing unit of our High Throughput platform. The solubility is ranked from 1 (excellent) to 6 (very poor). Based on these scores, the HSPiP software generates the solubility sphere of the tested product.
Following the increasing demand for bio-based alternatives, VLCI has set up a new workflow for HSP determinations using bio-based solvents. In partnership with multiple chemical suppliers, we have gathered more than 20 bio-based solvents spread across the HSP space, ensuring reliability and accuracy in our HSP determinations. This approach offers straightforward and practical insights about the applicability of the bio-based solvents across all industries.
VLCI offers HSP expertise combined with High Throughput capabilities to deliver fast, practical and accurate results.
