Phase diagram and emulsion stability of surfactant-fragrance systems.
Emulsions containing 95 wt.% water were prepared of a fragrance oil (limonene, the mixture of limonene and phenethyl alcohol in different ratios, and benzaldehyde), using a commercial tetraethyleneglycol lauryl ether (Laureth 4) as the stabilizer. The emulsion stability was observed both visually and with the aid of a microscope. The variation of emulsion stability with the fragrance/surfactant ratio is related to the phase changes in the system.
