Patent ID: 6998382

Claim:
A process for selecting a composition or product yielding a maximum fragrance burst of one or more of the fragrance components of at least 20% and for providing enhanced deposition of one or more fragrance components onto surfaces on which said composition or product comes into contact, when said composition is diluted, wherein said composition is defined by perfume burst index PBI: PBI = ϕ - 1.4 ⁢ / ⁢ CMC K wherein φ=oil/water partition coefficient of a selected perfume or perfume components in a mixture; CMC=critical micellization concentration (wt./wt.) of selected surfactant systems or mixture of surfactant systems in diluent or continuous phase; K=volatility constant of selected perfume from said continuous phase or diluent atmospheres); wherein said process comprises (1) selecting a perfume or at least one component of a first perfume mixture; (2) selecting a first surfactant system or mixture of surfactants systems; and (3) formulating said perfume or component of said first perfume mixture and said first surfactant system or mixture of surfactant systems to form said composition or product such that the above noted variables are calculated to provide a PBI that is greater than about 3; wherein by maximum fragrance burst of at least 20% is meant that the perfume concentration in the headspace above said fragrance or fragrance components increases at least 20% when it is diluted relative to the perfume concentration in the headspace of a second composition differing in perfume properties, surfactant concentration and/or CMC of a surfactant system with a PBI less than that of the first composition, both compositions measured as the compositions comprising said fragrance or fragrance components are diluted below the critical micelle concentration (CMC) of the fragrance, surfactant and water system.
