Hansen Solubility Parameters in Practice

Predictive Power

The HSPiP Software package Almost 50 years of successful applications of Hansen Solubility Parameters are captured in one package. If you don’t know about HSP then check out the simple summary on Wikipedia, or use your favourite search engine to discover just how many people in industry and academia are working every day to solve real-world problems in: polymers, solvents, nanoparticles, diffusion, fragrances and flavours, safety, printed electronics, organic photovoltaics, photoresists, plasticisers, food science. The key to the success of HSPiP is that provides the predictive power of HSP in a unified package with all the information and calculation tools ready for action.


HSPiP is an eBook, Software, a collection of Datasets and Working Examples all in one package. There are now HSP and other data on 10,000 chemicals in the current edition. The software doesn’t just calculate and visualise HSP in 3D, it has a solvent optimizer (up to 8 solvents, plus graphing of solvent mixture changes depending on Relative Evaporation Rates, Activity Coefficients and temperature), a polymer calculator, a DIY HSP calculator, a powerful Diffusion modeller. You can measure the HSP of liquids/oligomers via IGC. It even predicts GC and HPLC retention times for you! You can fit double spheres and sets of data values (e.g. solubilities) in addition to Yes/No solubilities. You can predict Vapour Liquid Equilibria and Azeotropes with the new powerful engine. With the new QSAR (Quantitative Structure Activity Relationships) capability there is the additional capability to fit datasets to meaningful parameter sets.

When we say that HSPiP has Predictive Power we really mean it. Formulators in the real world gain a powerful set of tools to point them towards the optimal solution to their formulation problems. We don't just say that, we use HSPiP's predictive power in our day jobs.

The eBook is over 300 pages and contains the minimum theory and maximum real-world experience to help you solve your solubility-related problems.

It’s everything you need in order to understand and apply HSP to your own field of expertise. To get a feel for its powerful capabilities (and for a fast-track training in how to use it) check out the Video Tutorials.

It was originally developed by two experts who use HSP to solve real-world problems and who are passionate about helping others use them too. And with Dr Hiroshi Yamamoto we have been able to add much more power to the basic HSP capabilities.

It shows how HSP solve problems in polymers, cleaning, paints, adhesion, coatings, quantum dots, bitumen, skin safety, HPLC, noses (artificial and natural), carbon nanotubes and C60, environmental stress cracking, diffusion, the environment, nano-clays, surfactants, (cyto)-toxicity and more.

It shows why HSP combine such power with such elegant simplicity.

It provides ways to calculate the HSP of molecules of interest to you via the classic (but limited) Hoy and Van Krevelen methods, via the latest correlations with measurable parameters such as dipole moment, via the Stefanis-Panayiotou group contribution method and via the fully automated Y-MB method from SMILES or Molfile inputs.

And it costs only $1195 (for an entire book and an entire software suite and a large collection of data sets) and can be downloaded/installed on any Windows 7, 8, 10 machine. From the 5th Edition it became 64x only so no longer runs on old XP and Vista machines. If you check out the price for other packages with far less functionality you will find that this is a bargain. Why such a small price for such a big package? Because we wanted HSP to become mainstream, and wanted to leave prospective users with no excuse for not getting to know about HSP. There is now a large users community who are constantly feeding back ideas and observations that help us to continue to develop the package. Click to find out how to purchase and install the package.

Because this is an all-electronic package you have access to free updates of the eBook and software. We will email you (this is the only unsolicited email we send to our users) when major updates are available and you download the latest package and are ready to go. Minor updates are made on a regular basis and you can check the updates log to see if it is worth downloading. The provision of free updates is an essential feature of the package. We believe that the HSP community can help expand and refine the capabilities of the technique and we want the package to grow with the community.
