AI Technical Summary

Benefits of technology

The composition effectively balances deposition and buildup on fabric surfaces, providing a consistent reddish-blue hue and improved fabric shading, addressing the limitations of existing dye interactions.

Problems solved by technology

This can lead to changes in the dye properties, such as deposition properties which may either not generate sufficient fabric shading or may lead to undesirable build up over time on fabric surfaces.

Abstract

Laundry care compositions comprising thiophene azo carboxylate fabric shading dyes and methods of treating a textile comprising such laundry care compositions.

Description

FIELD OF INVENTION[0001]This invention relates to laundry care compositions comprising fabric shading dyes and methods of treatment of fabrics using such compositions.BACKGROUND OF THE INVENTION[0002]As textile substrates age, their color tends to fade or yellow due to exposure to light, air, soil, and natural degradation of the fibers that comprise the substrates. To counteract this unwanted effect, laundry detergent manufacturers incorporate shading dyes into their products. The purpose of shading dyes is typically to counteract the fading and yellowing of the textile substrates by providing a blue-violet hue to the laundered fabrics, reducing the visual impact of the yellowing. In laundry care compositions dyes may be affected by interaction with laundry care adjuncts in the composition. This can lead to changes in the dye properties, such as deposition properties which may either not generate sufficient fabric shading or may lead to undesirable build up over time on fabric surfa...
