Claims (16)
- A granular detergent composition having a bulk density of at least 400 g/l, comprising 12.5 to 60 percent by weight of at least one nonionic surfactant; from 10 to 85 weight percent of a granular base comprising at least one builder; the base granules being impregnated with an intimate mixture of at least a portion of the nonionic surfactant and from 0.5 to 5 weight percent of at least one fatty acid having from 8 to 22 carbon atoms; and from 0.5 to 5 weight percent of at least one fatty alcohol having from 8 to 22 carbon atoms; the base granules also being impregnated with the balance of any of the nonionic surfactant not intimately mixed with the fatty alcohol and the fatty acid.
- A granular detergent composition according to claim 1 in which the base granules are impregnated with the fatty alcohol.
- A granular detergent composition according to claim 1 or claim 2 in which the base granules are impregnated with a first application of the nonionic surfactant in an amount less than the total amount of the nonionic surfactant, followed by a second application of an intimate mixture of the remaining amount of the nonionic surfactant, and the fatty acid and the fatty alcohol, wherein the combined amount of the fatty acid and the fatty alcohol is in the range from 3 to 16 (preferably 9-12) weight percent, based upon the total weight of nonionic surfactant and wherein the weight ratio of fatty acid:fatty alcohol is 0.7-1.2:1 (preferably 0.9-1.05:1), whereby the resulting concentration of the fatty acid and the fatty alcohol is greater at the surface of the base granules than the concentration at regions of the base granules other than at the surface.
- A granular detergent composition according to claim 3 in which at least 50% (preferably at least 65%) of the nonionic surfactant is impregnated first into the base granules.
- A granular detergent composition according to any of claims 1 to 4 in which the builder comprises a water-insoluble zeolite.
- A granular detergent composition according to any of claims 1 to 5 in which the fatty alcohol represents 0.75 to 1.25 weight percent and the fatty acid represents 0.75 to 1.25 weight percent.
- The use of a composition of matter for enhancing the dispensability of granular detergent compositions having a bulk density of at least 400 g/l, by impregnating the granular detergent with the composition of matter, the granular detergent comprising at least one builder, the composition of matter comprising an intimate mixture of at least one nonionic surfactant, at least one fatty acid having from 8 to 22 carbon atoms and at least one fatty alcohol having from 8 to 22 carbon atoms, wherein the combined amount of the fatty acid and the fatty alcohol is in the range from 3 to 16 (preferably 9 to 12) weight percent, based on the weight of the nonionic surfactant and wherein the amount of fatty acid relative to fatty alcohol is in the range of 0.7-1.2 (preferably 0.9-1.05) parts by weight fatty acid per part by weight fatty alcohol and whereby the final detergent composition comprises 10 to 85 weight percent of the builder, 12.5 to 60 weight percent of the nonionic surfactant, 0.5 to 5 weight percent of the fatty acid and 0.5 to 5 weight percent of the fatty alcohol.
- The use of composition of matter according to claim 7 wherein the fatty acid:fatty alcohol ratio is 0.9-1.05:1.
- The use of a composition of matter according to claim 7 or claim 8 wherein the fatty acid is stearic acid and the fatty alcohol comprises cetyl alcohol.
- The use of a composition of matter according to any of claims 7 to 9 in which the fatty alcohol represents 0.75 to 1.25 weight percent and the fatty acid represents 0.75 to 1.25 weight percent.
- A method for enhancing dispensability of granular detergent compositions having a bulk density of at least 400 g/l, which comprise at least one nonionic surfactant and at least one detergent builder, the method comprising: contacting 10 to 85 weight percent of a granular detergent base composition comprising at least one builder with a liquified intimate mixture comprising 12.5 to 60 weight percent of at least one nonionic surfactant, 0.5 to 5 weight percent of at least one fatty acid having from 8 to 22 carbon atoms and 0.5 to 5 weight percent of at least one fatty alcohol having from 8 to 22 carbon atoms.
- A method according to claim 11 wherein the granular detergent base composition is first contacted with at least a portion (preferably at least 50% and more preferably at least 65%) of the nonionic surfactant and subsequently contacted with the mixture comprising the remainder of the nonionic surfactant, fatty acid and fatty alcohol.
- A method according to claim 11 or claim 12 wherein the combined amount of the fatty acid and the fatty alcohol is in the range from 3 to 16 (preferably 9-12) weight percent, based on the weight of the nonionic surfactant and wherein the amount of fatty acid relative to fatty alcohol is in the range of 0.7-1.2 parts (preferably 0.9 to 1.05 parts) by weight fatty acid per part by weight fatty alcohol.
- A method according to any of claims 11 to 13 in which the fatty alcohol represents 0.75 to 1.25 weight percent and the fatty acid represents 0.75 to 1.25 weight percent.
- A composition according to any of claims 1 to 6 or a method according to any of claims 11 to 14 wherein the fatty acid is stearic acid and the fatty alcohol comprises cetyl alcohol.
- A method according to any of claims 11 to 14 wherein the builder comprises a water-insoluble zeolite.
