Compositions effective in removing protein, fat and/or starch based stains as well as oil and grease based stains from fabrics comprise organic solvents admixed with surfactants and an enzyme component wherein the enzymes are dissolved in aqueous solution and the aqueous solution is, in turn, dispersed as reversed micelles within the solvent surfactant mixture. Encapsulating the enzymes in reversed micelles protects them from degradation by the solvents and thereby prolongs the effectiveness of the enzymes for extended periods of time. The total water content of the compositions is kept below 5 weight% so that the compositions' oil and grease stain removal ability remains unimpaired. |
