WebWith the advent of HSPiP - Hansen Solubility Parameters in Practice which provides software, datasets and an eBook all in one package, the use of HSP has expanded considerably and its predictive power is easier to apply. … Hansen solubility parameters were developed by Charles M. Hansen in his Ph.D thesis in 1967 as a way of predicting if one material will dissolve in another and form a solution. They are based on the idea that like dissolves like where one molecule is defined as being 'like' another if it bonds to itself in a similar way. Specifically, each molecule is given three Hansen parameters, each generally measured in MPa :
