Patent ID: 7446079

Claim:
A method of formulating a perfume composition for wash-off systems, comprising: calculating values of odor detection threshold, odor detection threshold in air, acceleration (Γ) flash water release (Ω) values for a group of odorants; selecting at least three different odorants, each odorant having an acceleration (Γ) value of about 1000 or greater, a flash release (Ω) value selected from the group consisting of about 10 or greater, from about 0.07 to about 10, and from about 0.007 to about 0.07, and a property selected from the group consisting of an odor detection threshold of about 50 parts per billion or less, an odor detection threshold in air of about 0.025 mg/m 3 or less, and combinations of these; and placing the perfume composition in a wash-off system to provide an initial water release and a minimal residual perfume on a targeted surface after wash-off.
