A laundry product, such as a detergent composition, containing a mixture of dyes which results in laundry washed with the detergent being "blued" to a desired extent and with the desired shade of blue. The dyes employed are used in very small quantities, have little effect on the color of the laundry product, if it is in solid particulate form, are stable in alkaline media, such as crutcher mixes, and are readily bleachable by hypochlorite bleaches, so that objectionable overbluing effects need not be obtained on repeated washings. Preferred dyes employed are those of Index Numbers 24410 (Geigy, C.I. Direct Blue 1) and 29120 (Geigy, C.I. Direct Violet 66). |
