A laundry care composition comprises a laundry care ingredient or adjunct and at least one compound that is capable of changing from a first color state (i.e., the initial color state in the composition) to a second color state that is perceptibly different from the first color state. A method for treating textile articles comprises the steps of: (a) providing a laundry care composition as described above; (b) adding the laundry care composition to a liquid medium; and (c) placing the textile articles in the liquid medium.

Laundry care compositions

This application describes laundry care compositions that contain leuco colorants and their use in the laundering of textile articles. These types of colorants are provided in a stable, substantially colorless state and then may be transformed to an intense colored state upon exposure to certain physical or chemical changes such as, for example, exposure to oxygen, ion addition, exposure to light, and the like. The laundry care compositions containing the leuco colorants are designed to enhance the apparent or visually perceived whiteness of, or to impart a desired hue to, textile articles washed or otherwise treated with the laundry care composition.
