The solubilization of synthetic perfumes (eugenol, linalool, benzyl acetate, α-ionone, α-hexyl cinnamaldehyde, and <I>d</I>-limonene) by sodium dodecyl sulfate (SDS) has been studied in regard to maximum additive concentration, solubilizing power, solubilized micelle size, polarity of the micellar interior, partition coefficient, partial molar volume and volatility speed. It was found that, the more hydrophilic are the synthetic perfumes, the greater are the maximum additive concentration and solubilizing power. The synthetic perfumes deeply penetrated the palisade layer of SDS micelles, the extent of which depended on the decrease in their hydrophilic property. The polarity of micellar interior decreased with increase in the amount of synthetic perfume dissolved, except for α-Ionone and α-hexyl cinnamaldehyde. The partition coefficient between the micelle and bulk phases decreased with increase in the solubility. The partial molar volumes of synthetic perfumes dissolved were less than those of pure synthetic perfumes. Volatility speed from micelle solution was influenced by the partition coefficient between the micelle and bulk phase.
