6 It is the square root of the cohesive energy density (cal/cc) Thisparameter gives an accurate estimation of the interaction energies inmany diverse systems. It can be used to predict the solubility interactions of cosmetic It can be used to predict the solubility interactions of cosmeticmaterials in formulated products. The solubility parameter of a particular material can be directlymeasured by a variety of methods or it can be calculated The parameter can be calculated by adding up the component parts andthen used to predict possible uses, probable substitutions and potentialproblem interactions. A general guideline is that if the solubility parameters for two or morematerials are within +/- (cal/cc) , they are PAO - Solubility Parameters: Fedors CorrelationProduct Solubility Parameter (cal/cc) PureSyn 2 PureSyn 4 PureSyn 4 PureSyn 6 PureSyn 150 PureSyn 300 PureSyn PAO Surface Tension Measurements Product Dynes/cm (24 C) PureSyn 2 PureSyn 4 PureSyn 6 PureSyn 6 PureSyn 150 PureSyn 300 Measurement Procedure;PureSyn 2 -100; Wilhelmy Plate MethodPureSyn 150 -3000; Spinning Drop MethodPureSyn PAO Refractive IndicesProduct @ 25oC PureSyn 2 PureSyn 4 PureSyn 6 PureSyn 150 PureSyn 150 PureSyn 300 Mineral Oils PureSyn PAO Potential Attributes in personal care applications Provide a broad range of spreadability values that may be used tocustomize skin feel.
