Definitions

• the present invention solves the long-standing need for detergent compositions which provide efficient and effective performance over a wide range of cleaning needs by combining the cleaning actions of enzymes with the hydrophobic cleaning action of amido derived bleach activators or with the hydrophobic and hydrophilic cleaning action of N-acyl caprolactam bleach activators.
• the invention also provides efficient and effective detergent compositions for use in washing machines which have parts made of natural rubber, such that the natural rubber is substantially undamaged by the bleaching system.
• the present invention encompasses detergent compositions comprising an effective amount of one or more types of enzymes and a bleaching system comprising at least about 0.1%, by weight, of a peroxygen bleaching compound and at least about 0.1%, by weight, of one or more bleach activators, wherein said bleach activators are members selected from the group consisting of: a) a bleach activator of the general formula:
• the detergent compositions employed in the present invention provide effective and efficient surface cleaning of fabrics which thereby removes stains and/or soils from the fabrics.
• the bleaching systems in combination with one or more types of enzymes are particularly efficient at removing most types of soils from the fabrics, including protein and lipid soils, dingy soils, and heavy soil loads, especiaUy from nucleophilic and body soils.
• aluminosilicates can be crystalline or amorphous in structure and can be naturally-occurring aluminosilicates or synthetically derived.
• Methods for producing aluminosilicate ion exchange materials are disclosed in U.S. Patent 3,985,669, Krummel, et al, issued October 12, 1976, and U.S. Patent 4,605,509, Corkill, et al, issued Aug. 12, 1986.
• Preferred synthetic crystalline aluminosilicate ion exchange materials useful herein are available under the designations Zeolite A, ZeoUte P (B) (including those disclosed in EPO 384,070), and Zeolite X.
• the aluminosilicate has a particle size of about 0.1-10 microns in diameter.
• Citrate builders e.g., citric acid and soluble salts thereof (particularly sodium salt), are preferred polycarboxylate builders that can also be used in granular compositions, especially in combination with zeolite and/or layered silicate builders. Also suitable in the detergent compositions of the present invention are the 3,3-dicarboxy-4-oxa-l,6-hexanedioates and the related compounds disclosed in U.S. Patent 4,566,984, Bush, issued January 28, 1986.
• the various alkali metal phosphates such as the well-known sodium tripolyphosphates, sodium pyrophosphate and sodium orthophosphate can be used.

• the fabrics are laundered at 40°C (104°F) for a full cycle (40 min.) and rinsed at 21°C (70°F).
• the laundering method is repeated for 2,000 wash cycles without rupture of, or significant damage to, the natural rubber parts and with good enzyme stability and performance.
• EXAMPLE V ⁇ i A detergent composition is prepared by a procedure identical to that of Example V, with the exceptions that 15% of a 1:1:1 mixture of benzoyl caprolactam, nonanoyl caprolactam and (6-nonanamidocaproyl)oxybenzene-sulfonate as prepared following Example HI is substituted for the nonanoyl caprolactam and the amount of sodium percarbonate is 30%.
• the laundering method of Example V is repeated for 2,000 cycles without rupture of, or significant damage to, the natural rubber parts and with good enzyme stability and performance.
• EXAMPLE XIV A detergent composition is prepared by a procedure identical to that of Example XII, with the single exception that an equivalent amount of nonanoyl caprolactam is substituted for the (6-ncnanamidocaproyl)oxybenzenesulfonate. The laundering method of Example XII is repeated for 2,000 cycles without rupture of, or significant damage to, the natural rubber parts and with good enzyme stability and performance.
• Example V Testing is conducted following the procedures and methods in Example V.
• the laundering method of Example V is repeated for 2,000 cycles without rupture of, or significant damage to, the natural rubber parts and with good enzyme stability and performance.
• Example V Testing is conducted following the procedures and methods in Example V.

Testing is conducted following the procedures and methods in Example V.
• EXAMPLE XXI A detergent composition is prepared by a procedure identical to that of Example XV, with the exceptions that 15%, by weight, of (6-decanamidocaproyl)- oxybenzenesulfonate activator is substituted for the nonanoyl caprolactam and the amount of sodium percarbonate is 30%.
• the bleach activators may be processed with a range of organic and inorganic substances to achieve a rapid dispersion in the bleaching liquor and to insure good stability in the detergent composition.
• the bleach activators are preferably employed in paniculate form.
• An example of preferred caprolactam bleach activator particles is an agglomerate of about 65%, by weight, benzoyl caprolactam; about 7% of a builder, such as aluminium silicate; about 15% sodium carbonate; about 9% dispersant, such as a polyacrylate polymer; and about 4% of a solubilizing agent, such as a linear alkyl sulfonate.
• Another example of a preferred caprolactam bleach activator particle is an agglomerate of about 80% to about 85%, by weight, benzoyl caprolactam and about 15% to about 20% of a binder, such as tallow alcohol ethoxylate, preferably TAE25.

• the particle size of the resulting granules may be varied according to the desired performance/stability. Fine particles ( ⁇ 250 um) show improved solubility; though coarse particles (>1180 um) are more stable in high temperatures/moist environments. A typical, preferred particle size range is 250-1180 um; particles conforming to this specification show excellent stability and solubility.
