Phase diagrams of surfactant/water/synthetic perfume ternary systems

Abstract

The phase diagrams of hexadecyl polyoxyethylene ether (C₁₆POE₁₀)/water/synthetic perfume, and sodium dodecyl sulfate (SDS)/water/synthetic perfume ternary systems were prepared. The synthetic perfumes used are, d-limonene, α-hexylcinnamaldehyde, α-ionone, benzyl acetate, linalool, and eugenol. In a series of C₁₆POE₁₀/water/synthetic perfume ternary systems, as the hydrophilicity of synthetic perfume increases, the regions of normal and inverse micellar solution phases were found to be extended, while that of the lamellar liquid crystal phase was reduced. Moreover, every region of normal micellar solutions, inverse micellar solutions, and lamellar liquid crystal phases in SDS/water/synthetic perfume ternary systems was found to be smaller than those in C₁₆POE₁₀/water/synthetic perfume systems.
