摘要： 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).
摘要翻译：洗涤产品，例如洗涤剂组合物，其含有将洗涤剂洗涤的洗涤剂的混合物的混合物“蓝色”到期望的程度并具有所需的蓝色。所使用的染料以非常少的量使用，如果它是固体颗粒形式，在碱性介质如搅拌器混合物中是稳定的，并且易于被次氯酸盐漂白剂漂洗，对洗衣产品的颜色几乎没有影响，使得反复洗涤时不需要得到令人反感的过度冲击效果。所使用的优选染料是索引号24410（Geigy，C.I.直接蓝1）和29120（Geigy，C.I.Direct Violet 66）的染料。

摘要： IMPROVED WHITENING AND BRIGHTENING OF LAUNDRY, ESPECIALLY COTTON ARTICLES, ARE OBTAINED BY TREATING SUCH LAUNDRY WITH AN AQUEOUS SOLUTION OF BLUE DYE OR MIXTURE OF SUCH DYES WHICH IS SUBSTANTIVE TO THE ARTICLES OF LAUNDRY AND IS CAPABLE OF TINTING THEM WITH A SLIGHT BLUE COLOR, REMOVABLE BY A CHLORINE BLEACH, AND A FLUORESCENT BRIGHTENER SUBSTANTIVE TO THE ARTICLES AND RESISTANT TO CHLORINE AND SUNLIGHT BLEACHING. THE DYE OR MIXTURE OF DYES GIVES THE LAUNDRY A DESIRABLE BLUE TINT WHEN IT IS NOT SUBJECTED TO CHLORINE OR SUNLIGHT BLEACHING AAND WHEN SUCH BLEACHING IS AFFECTED AND THE BLUE IS BLEACHED (IT IS NO LONGER NEEDED TO COUNTERACT ANY YELLOW OF THE LAUNDRY BECAUSE THAT, TOO IS BLEACHED) THE BLEACH-STABLE BRIGHTENER EXERTS ITS BRIGHTENING EFFECT. UNLIKE TREATMENTS WHERIN BLEACHRESISTANT DYES ARE EMPLOYED, ANY BUILD UP OF BLUING DUE TO REPEATED TREATMENTS MAY BE REMOVED. ALSO DISCLOSED ARE COMPOSITIONS OF SUCH MIXED DYES AND BRIGHTENER, AND DETERGENT COMPOSITIONS CONTAINING THEM.
