Abstract

A detergent composition containing cellulase and perfume is provided. Specifically, the detergent composition comprises: (a) a cellulase enzyme; and (b) a perfume containing at least 25% by weight of at least one fragrance material selected from the group consisting of aliphatic ketones with a molecular weight of between 200 and 350 AMU, aromatic ketones with a molecular weight of between 150 and 350 AMU, aliphatic aldehydes with a molecular weight of between 160 and 350 AMU, aromatic aldehydes with a molecular weight of between 150 and 350 AMU, condensation products of aldehydes and amines with a molecular weight between 190 and 350 AMU, aromatic and aliphatic lactones with a molecular weight between 140 and 350 AMU, aromatic and aliphatic ethers with a molecular weight between 150 and 350 AMU, aliphatic alcohols with a molecular weight between 200 and 350 AMU, aromatic and aliphatic esters with a molecular weight between 190 and 350 AMU and mixtures thereof. The perfume is substantially free of halogenated fragrance materials and nitromusks.

What is claimed is: 
     
       1. A detergent composition comprising: (a) a cellulase enzyme; and   (b) a perfume containing at least 25% by weight of at least one fragrance material selected from the group consisting of aliphatic ketones with a molecular weight of between 200 and 350 AMU, aromatic ketones with a molecular weight of between 150 and 350 AMU, aliphatic aldehydes with a molecular weight of between 160 and 350 AMU, aromatic aldehydes with a molecular weight of between 150 and 350 AMU, condensation products of aldehydes and amines with a molecular weight between 190 and 350 AMU, aromatic and aliphatic lactones with a molecular weight between 140 and 350 AMU, aromatic and aliphatic ethers with a molecular weight between 150 and 350 AMU, aliphatic alcohols with a molecular weight between 200 and 350 AMU, aromatic and aliphatic esters with a molecular weight between 190 and 350 AMU and mixtures thereof; wherein said perfume is substantially free of halogenated fragrance materials and nitromusks.     
     
     
       2. The detergent composition of claim 1 wherein said enzyme is a fungal cellulase. 
     
     
       3. The detergent composition of claim 1 further comprising from about 1% to about 55% of a surfactant. 
     
     
       4. The detergent composition of claim 3 wherein said surfactant is selected from the group consisting of alkyl benzene sulfonates, alkyl ester sulfonates, alkyl ethoxylates, alkyl phenol alkoxylates, alkylpolyglucosides, alkyl sulfates, alkyl ethoxy sulfate, secondary alkyl sulfates and mixtures thereof. 
     
     
       5. The detergent composition of claim 1 further comprising at least about 1% by weight of a detergency builder. 
     
     
       6. The detergent composition of claim 1 wherein said perfume is present in an amount from about 0.001% to about 5% by weight of said composition. 
     
     
       7. The detergent composition of claim 1 further comprising adjunct ingredients selected from the group consisting of bleaches, bleach activators, suds suppressors, enzyme stabilizers, polymeric dispersing agents, dye transfer inhibitors, soil release agents and mixtures thereof. 
     
     
       8. The detergent composition of claim 1 wherein said composition is in the form of agglomerates and the density of said detergent composition is at least about 650 g/l. 
     
     
       9. The detergent composition of claim 1 further comprising a polyhydroxy fatty acid amide for use as a surfactant. 
     
     
       10. A detergent composition according to claim 1 wherein said composition is in the form of a laundry bar. 
     
     
       11. A detergent composition according to claim 1 wherein said composition is in the form of a liquid. 
     
     
       12. A method of laundering fabrics comprising the step of contacting said fabrics with an aqueous medium containing an effective amount of a detergent composition according to claim 1.
