Abstract
Well-defined tetraethylene glycol monooctylether (C8E4) and its commercial polydispersed counterpart (Dehydol(R) O4) were used to solubilize fragrances. Addition of small amounts (<= 1 wt.%) of the ionic surfactants, sodium dodecylsulfate (SDS) or sodium lauryl ether sulfate (SLES), permits the formulation of temperature insensitive fragrance in water microemulsions. The investigation of the pseudo-ternary surfactants/beta-pinene/water systems allows the determination of the optimum temperature T* as well as the assessment of the efficiency of the surfactant mixtures to solubilize beta-pinene. A mixture of Dehydol O4 and SDS (9/1 wt.%) can solubilize 6.5 wt.% of beta-pinene in water within the temperature range of 25-80 degrees C. This synergistic formulation was also applied to the solubilization of p-cymene, the essential oils pinus pinaster and pinus sylvestris and a true fragrant mixture composed of 9 terpenes and terpenoids in dipropylene glycol.
