Abstract:

Textiles are often contaminated by coloring matters in daily use. It is difficult to remove these colored stains by using traditional household washing detergents. Peroxides can be used as bleaching agents to remove these colored stains from textiles, however, at relatively high temperatures. Activated peroxide systems are established by adding so-called bleach activators that can react with hydrogen peroxide released from peroxides to generate more kinetically active bleaching species that can break down colored stains at lower temperatures. In this paper, N-[4-(triethylammoniomethyl)benzoyl]caprolactam chloride (TBCC) and tetraacetylethylenediamine (TAED) were used as bleach activators to establish activated peroxide systems in which sodium dodecylbenzenesulfonate (SDBS) and stearyltrimethylammoium chloride (STAC) were added. The formula was designed, aiming to remove colored stains from textiles at room temperature. Morin and coffee were used to simulate the colored stains on textiles. In near-neutral conditions at room temperature, it was found that surfactants themselves could not remove colored stains from textiles, but the ionic charges on these surfactants could interact with the activated peroxide systems and affect their performance on removing colored stains. The formula of activated peroxide system based on TBCC and SDBS was able to effectively remove colored stains from textiles at room temperature. This study might contribute to developing effective household washing formulations for cleaning textiles stained with colored substances.
