Brightening agents are essentially colorless dyes which, when applied on textiles, absorb ultraviolet irradiation and emit light of a bluish hue complementary to the yellow tint already present on the off-white substrate. In this manner the brightening agents impart a greater apparent whiteness to the materials treated. Although brighteners were originally applied to paper — and continue to be — they were incorporated in detergent compositions about 1945. At present the growth of this application has expanded to the point where brightening agents are available for most types of fiber and detergent compositions. The literature on brightener evaluation methods has grown to a point where a bibliography of the published methods should prove useful to the persons engaged in the manufacture, analysis, development, and evaluations of brignteners in detergents. Accordingly, this bibliography has been prepared by Mr. Weeks of Subcommittee T-5 on Physical Testing of Committee D-12 on Soaps and Other Detergents. Some of the abstracts pertain to the evaluation of brighteners on paper. The style of this bibliography follows closely that of “Metal Cleaning Bibliographical Abstracts.” The references, which are numbered consecutively, are listed by year and then by author or by the journal in which the article appeared if anonymous. Most of the abstracts are based on the original article; some are re-abstracts from “Chemical Abstracts.”
