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.

The present disclosure provides a laundry care composition having at least one laundry care ingredient and at least one leuco composition conforming to Formula (I):
Ar.sup.1Ar.sup.2Ar.sup.3CH  (I)
wherein Ar.sup.2 and Ar.sup.3 are independently a carbocyclic aryl or heteroaryl, and Ar.sup.1 is selected from the group consisting of: unsubstituted phenyl, electron deficient carbocyclic aryl, and heteroaryl. The present disclosure also provides a method of determining an authentic laundry care composition and test kits for detecting authentic laundry care compositions.

The present disclosure concerns the design, formulations, preparations and optical properties of compounds of Formulas (I) and (VI):

(charged dye.sup.m+).sub.x.Math.(counterion.sup.n−).sub.y.Math.(counterion receptor).sub.z  (I) and

(charged dye.sup.m−).sub.x.Math.(counterion.sup.n+)y.Math.(counterion receptor).sub.z  (VI).

The charged dye.sup.m+ is a cationic dye, counterion.sup.n− is an anion, and counterion receptor is a binding ligand for the counterion.sup.n−, wherein m, n, x and y are integers greater than or equal to 1, and products of x.Math.n and m.Math.y are identical for formula (I).

The charged dye.sup.m− is a anionic dye, counterion.sup.n+ is a cation, and counterion receptor is a binding ligand for the counterion.sup.n+, wherein m, n, x and y are integers greater than or equal to 1, and products of x.Math.n and m.Math.y are identical for formula (VI).

A laundry care composition including (a) at least one laundry care ingredient and (b) a leuco composition. The leuco composition has a first color state and a second color state and the mole ratio of second color state to first color state is from 2:98 to 5:95. Also disclosed are methods of determining the approximate functional age of a laundry care composition comprising the steps of (a) providing a laundry care composition that includes at least one laundry care ingredient and a leuco composition, (b) providing a functional age scale that includes a plurality of distinct colors that correspond to a unique functional age and (c) comparing the color of the laundry care composition with the functional age scale.

Tissue-regenerating wound treatments, methods of producing tissue-regenerating wound treatments, and methods of treating a wound using a tissue-regenerating wound treatment are provided. The tissue-regenerating wound treatment includes a skin substitute and a coloring agent added to the skin substitute. The coloring agent is a biocompatible coloring agent that degrades upon protease attack within a treated wound.

A method for treating textile articles including the steps of: (a) providing a laundry care composition comprising a leuco composition; (b) adding the laundry care composition to a liquid medium; (c) placing the textile articles in contact with the liquid medium; (d) depositing at least some portion of the leuco composition onto the textile articles; (e) optionally, rinsing the textile; and (f) drying the textile articles, wherein the leuco composition comprises a leuco colorant with a Photoresistance Index of less than or equal to 30.

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.
