Leuco polymers as bluing agents in laundry care compositions

Abstract

A leuco polymer comprising a polymeric carbohydrate and a leuco moiety. The polymeric carbohydrate and the leuco moiety are covalently bound. Methods of making the leuco polymer, laundry care compositions comprising the leuco polymer and methods of treating textiles with such laundry care compositions.

Description

technical field [0001] The present application describes laundry care compositions comprising leuco polymers and their use in textile laundering. These types of leuco polymers are provided in a stable, essentially colorless state, which can then be transformed into an intensely colored state. Laundry care compositions containing leuco polymers are designed to enhance the apparent or visually perceived whiteness, or impart a desired hue, of textiles washed or otherwise treated with the laundry care composition. Background technique [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 make up the substrate. Therefore, to visually enhance these textile substrates and to counteract fading and yellowing, the use of polymeric colorants to color consumer products is well known in the art. For example, the use of brighteners, optical brighteners or bluing agents in textile applicatio...

Problems solved by technology

However, when used at levels that provide consumers with significant whiteness benefits, traditional brighteners can adversely affect finished aesthetics or, if highly deposited, create cumulative problems over time and over-tinting
