Formulation Proposal Using HSP Value
Formulation Proposal
We design the optimum solvent you desire by using the solubility value (Hansen Solubility Parameters), which is an index of the affinity between substances.We propose a formulation to change from a highly hazardous solvent to an environment-friendly blended solvent based on the idea that "those with similar HSP values are compatible," keeping in mind what solvent the polymer dissolves in, how stable various additives can exist, etc.
Cleaning, dissolving, legal compliance, etc....
Andoh Parachemie will solve your worries!
Solvent Development Using HSP Value
Materials with similar three intermolecular energies bond well
ΔD：Dispersion energy between molecules ΔP： Dipole interaction energy between molecules ΔH：Intramolecular hydrogen bond energy - }
- Three parameters are shown in 3D space
and each property is predicted by each positional relationship.
Good solubility if the spatial coordinates of different substances are close to one another.
| Solvent | ΔD | ΔP | ΔH |
|---|---|---|---|
| n-Hexane | 15.3 | 0 | 0 |
| Tetrahydrofuran | 16.8 | 5.7 | 8.0 |
| Ethanol | 15.8 | 8.8 | 19.4 |
| N,N-dimethylformamide(DMF) | 17.4 | 13.7 | 11.3 |
possible by controlling the HSP Value by combining various raw materials handled

Use of HSP value is not limited to application to alternative solvents.Below are some examples of other ideas
- Liquid and liquid, solid and liquid, gas and liquid
- Affinity between inorganic and organic, biological and organic substances (wetness, etc.)
- Solubility of polymer and solvent
Application example
High resilience agent for golf balls, eye drops that will be absorbed well by the eyes, dispersion of silica particles, antioxidation of solvents, etc.
