Abstract
Official abstract text for this publication.
A method of treating a fabric, the method comprising the step of: subjecting the fabric to a wash liquor comprising from 100 ppm to 600 ppm of a surfactant system; and rising the fabric with a rinse liquor comprising from about 1×10 2 to about 1×10 8 CFU/l of the aqueous liquor, of bacterial spores.
First claim
Opening claim text (preview).
1 . A method of treating a fabric, the method comprising the step of: i. subjecting the fabric to a wash liquor comprising from about 100 ppm to about 600 ppm of a surfactant system; and ii. rising the fabric with a rinse liquor comprising from about 1×10 2 to about 1×10 8 CFU/l of the aqueous liquor, of bacterial spores. 2 . The method according to claim 1 , wherein the surfactant system comprises an anionic and a nonionic surfactant. 3 . The method according to claim 1 , wherein the surfactant system comprises an anionic and a nonionic surfactant and wherein the anionic surfactant comprises a sulfonate and/or sulfate surfactant and the nonionic surfactant comprises and alcohol ethoxylated. 4 . The method according to claim 1 , wherein the surfactant system comprises an anionic and a nonionic surfactant and wherein the anionic surfactant comprises linear alkylbenzene sulfonate and alcohol ether sulfate. 5 . The method according to the claim 1 , wherein the surfactant system comprises an anionic and a nonionic surfactant and wherein the anionic to nonionic surfactant are in a weight ratio of from about 30:1 to about 1:2. 6 . The method according to the claim 1 , wherein the surfactant system comprises an anionic and a nonionic surfactant and wherein the anionic to nonionic surfactant are in a weight ratio of from about 20:1 to about 2:3. 7 . The method according to claim 1 , wherein the rinse liquor comprises from about 1×10 3 to about 1×10 7 CFU/l of the aqueous liquor, of bacterial spores. 8 . The method according to claim 1 , wherein the bacterial spores comprise Bacillus spores, p Bacillus selected from the group consisting of Bacillus subtilis, Bacillus amyloliquefaciens, Bacillus licheniformis, Bacillus megaterium, Bacillus pumilus, Bacillus cereus, Bacillus thuringiensis, Bacillus mycoides, Bacillus tequilensis, Bacillus vallismortis, Bacillus mojavensis and mixtures thereof, or selected from the group consisting of Bacillus subtilis, Bacillus amyloliquefaciens, Bacillus licheniformis, Bacillus megaterium, Bacillus pumilus and mixtures thereof. 9 . The method according to claim 1 , wherein the surfactant system is added to the wash liquor as part of a fully formulated detergent. 10 . The method according to claim 1 , wherein the surfactant system is added to the wash liquor as part of a fully formulated detergent and wherein the fully formulated detergent further comprises a cleaning adjunct. 11 . The method according to claim 1 , wherein fully formulated detergent is in liquid, solid or unit-dose from. 12 . The method according to claim 1 , wherein the method takes place in a washing machine comprising an auto-dosing system, wherein the auto-dosing system comprises a plurality of reservoirs, one reservoir comprising one or more surfactants and at least another reservoir comprising the bacterial spores. 13 . The method according to claim 1 , wherein the wash liquor is substantially free of bleach. 14 . The method according to claim 1 , wherein the rinse liquor is substantially free of fabric conditioning agent.
