The solubility parameter δ is a thermodynamic quantity introduced by Hildebrand and Scatchard (HS) to describe the behavior of the so-called regular solutions. Such solutions have a negligible mixing volume and excess entropy of mixing, so that the excess Gibbs free energy coincides with the mixing enthalpy.

"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 : " - Solubility parameter คือ
