  • Stabilized bleach-sensitive dyes in automatic dishwasher detergent compositions
    Patent number: 4464281
    Abstract: A method for stabilizing automatic dishwasher detergents containing bleach-sensitive dyes against decolorization by the bleaching agents of the compositions. The detergent powders comprise about 5-70% of a builder, 1-15% of a nonionic surfactant, 1-20% of a silicate, 0-60% of a filler, 0.001-0.1% of a bleach-sensitive dye, water and a bleaching agent. Prior to the addition of bleaching agent, the composition is pre-conditioned by contact with a flow of air. The resultant powder has a color that remains essentially unchanged even after storage for two months at elevated temperatures.
