Abstract

Solubilization of the synthetic perfumes, eugenol, linalool, benzyl acetate, α-ionone, α-hexylcinnamaldehyde and d-limonene by the ionic surfactants, sodium dodecyl sulfate (SDS) and do-decyltrimethylammonium chloride (DTAC) and a non-ionic surfactant such as dodecyl polyoxyethylene ethers (C12POE20) was investigated and assessed in terms of solubilizing capacity (SC) of the surfactants. For the same perfume, except for LN, SC followed the order, C12POE20>SDS>DTAC. On the other hand, the order of SC for LN was C12POE20>DTA>SDS. The relative importance of micelle-perfume interactions and of volume of effective solubilization site in micelle may be explanation for these findings.
