Method for increasing brightness retention of laundered fabrics |
| abstract |
The invention provides a method for increasing the brightness retention of a laundered fabric after numerous washing cycles by adding to an aqueous wash liquor a quantity of a commercial laundry detergent which delivers at least 0.1 g of an optical brightener into said wash liquor; and prior to, concurrent with, or after the commercial laundry detergent, adding a bleachi ng composition in an amount of at least about 0.5g/L. The bleaching composition contains about 2.5-10% alkali metal hypochlorite; about 0.05-5% of a bleach stable surfactant bearing at least one nitrogen atom; a bleach stable anioni c surfactant or a hydrotrope, wherein the ratio of (ii) to (iii) is between about 10:1 to about 1:10; and an effective amount of a source of alkalinity. The fabric is repeatedly washed and the optical brightener is enabled to deposit on the fabric to increase versus a control a Stensby whiteness measure of at least about .DELTA. W=4. |
