Patent ID: 8207101

Claim:
A method of delivering enhanced fragrance smell or detection by consumer from container comprising undiluted liquid body wash formulation relative to other containers comprising liquid wash formulation which method comprises formulating specific perfume components into concentrated liquid wherein said concentrate liquid is as set forth below: 1) 40 to 80% by wt. fatty acid and/or soap; 2) 0 to 25% by wt. synthetic non-soap surfactant; 3) 10 to 65% by wt. solvent which may be combination of water and/or co-solvents preferably selected from alkylene glycol; 4) 0.01 to 3.0% perfume component with a polarity greater than 4 MPa 1/2 ; and wherein said perfume component comprises a benzene ring having attached, to at least one position on the ring, a C 1 -C 6 alkyl group containing a functional group selected from the group consisting of alcohol, acetate, aldehyde and mixtures thereof; wherein concentrate has a viscosity of between 10,000 and 100,000 cps, as measured at 20° C. in Brookfield Viscometer after two (2) minutes at 10 rpm using Spindle RV7 wherein, when criticalities of perfume and soap-based concentrates are met, when measuring against a non-concentrate liquid soap-based composition comprising 10-30% fatty acid soap and less than 30% total surfactant, said concentrate has a perfume efficiency coefficient (PEC as defined) of >1 measuring undiluted concentrate versus undiluted non-concentrate.
