There is some disagreement within the surfactant literature as to the exact definition of solubilization, particularly as the ratio of surfactant to additive decreases, and one approaches the nebulous frontier between swollen micellar systems and the micro- and macroemulsion regions. For present purposes, solubilization will be defined as the preparation of a thermodynamically stable, isotropic solution of a substance (the additive ) normally insoluble or only slightly soluble in a given solvent by the addition of one or more amphiphilic compounds at or above their critical micelle concentration. By the use of such a definition, a broad area can be covered that includes both dilute and concentrated surfactant solutions, aqueous and nonaqueous solvents, all classes of surfactants and additives, and the effects of complex interactions such as mixed micelle formation and hydrotropes. It does not, however, limit the phenomenon to any single mechanism of action. 

Hydrotropes are a class of compounds widely used in industrial applications for their outstanding ability to enhance the aqueous solubility of hydrophobic compounds and surfactants. Very different chemical families can lead to a hydrotropic behaviour and the hydrotropy phenomenon has not been clearly elucidated so far. No definite structure-properties relationships have been established either. The common feature is that hydrotropes exhibit amphiphilicity and can be regarded as weak surfactants, with some similarities in their behaviours in water. This chapter focuses on hydrotropes obtained from sugars and polyols, such as glycerol, sorbitol and isosorbide, which represent relatively new and promising alternatives to the currently used hydrotropes from petroleum origin. Emphasis is put on the preparation of such amphiphiles and on their specific physico-chemical properties.
