Four perfumes which volatilize relatively readily (leaf alcohol, d-limonene, n-nonyl aldehyde and l-rose oxide) were dissolved in aqueous ethanol and the volatility behaviors of these perfumes were examined with headspace gas chromatography.Keratin powder and cellulose powder were used as supports for perfuming. As the result, it was ascertained that the differences of the treated supports were measured by using keratin powder and cellulose powder. It was confirmed that the differences in characteristics of perfumes occur when different supports were used.When the water/ethanol ratio in aqueous ethanol was varied, rate of volatility remained relatively constant. However, concentration of each perfume in vapor phase was altered.The effect of the use of low vapor pressure solvents (benzyl benzoate, diethyl phthalate, dipropylene glycol, liquid isoparaffin, and decamethyl cyclopentasiloxane) was examined. As the result, liquid isoparaffin and decamethyl cyclopentasiloxane showed retentive effects.
