ABSTRACT:
A dye composition is disclosed together with methods for its use and detergent compositions employing the combination. The dye composition is a mixture of anthraquinone dyes suitable for use with liquid laundry detergents. The composition substantially reduces the undesirable fabric staining characteristic of a detergent in which the dye is employed, while still retaining the ability to blue the fabric. Further, the color value of the detergent product is maintained at a desirable level. The composition is a combination of an oil soluble dye such as 1,4-bis(2-ethylhexylamino)-anthraquinone (C.I. Solvent Blue 58) with a water soluble dye such as 1-amino-2-sulfo, 4-(2-sulfo-para toluidino) anthraquinone sodium salt (C.I. Acid Blue 145) and/or 1,4-bis(3-sodium sulfonate mesitylidino) anthraquinone (C.I. Acid Blue 80).
