and Compositions Comprising the Same

TECHNICAL FIELD

This application describes leuco compositions, laundry care compositions containing such leuco compositions, and the use of such compositions in the laundering of textile articles. These types of compositions 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 compounds 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.

BACKGROUND

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. As such, to visually enhance these textile substrates and counteract the fading and yellowing the use of polymeric colorants for coloring consumer products has become well known in the prior art. For example, it is well known to use whitening agents, either optical brighteners or blueing agents, in textile applications. However, traditional whitening agents tend to lose efficacy upon storage due to deleterious interactions with other formulation components (such as, for example, perfumes). Further, such whitening agents can suffer from poor deposition on textile substrates. As such, formulators tend to increase the level of whitening agent used to counteract any efficacy lost upon storage and/or to increase the amount of whitening agent available to deposit on the textile substrate.

Leuco dyes are also known in the prior art to exhibit a change from a colorless or slightly colored state to a colored state upon exposure to specific chemical or physical triggers. The change in coloration that occurs is typically visually perceptible to the human eye. Many of these compounds have some absorbance in the visible light region (400-750 nm), and thus more or less have some color. In this invention, a dye is considered as a "leuco dye" if it did not render a significant color at its application concentration and conditions, but renders a significant color in its triggered form. The color change upon triggering stems from the change of the molar attenuation coefficient (also known as molar extinction coefficient, molar absorption coefficient, and/or molar absorptivity in some literatures) of the leuco dye molecule in the 400-750 nm range, preferably in the 500-650 nm range, and most preferably in the 530-620 nm range. The increase of the molar attenuation coefficient of a leuco dye before and after the triggering should be greater than 50%, more preferably greater than 200%, and most preferable greater than 500%.

Leuco compounds can be used as whitening agents in laundry care compositions (e.g., laundry detergents). In such uses, the addition of the leuco compound, which is an uncolored or only lightly colored state, does not significantly affect the aesthetics of the laundry care composition. Then, the leuco compound can be converted to a colored state in which it imparts the desired whitening benefit to the textile substrate. One class of leuco compounds that has been found to be particularly useful in such uses are triarylmethane leuco compounds. In such applications, it is sometimes beneficial to utilize a broad distribution of tirarylmethane leuco compounds having different polymeric groups attached to each compound. Typically, this requires an admixture of individually synthesized triarylmethane leuco compounds, each of which covers a portion of the targeted distribution. Producing a series of such individually synthesized triarylmethane leuco compounds can be tedious. Thus, there is a continuing need to provide a streamlined synthetic approach and a composition produced by such approach.

It has now surprisingly been found that a composition containing a broad distribution of polymeric triarylmethane leuco compounds can be obtained by admixing a suitable number of aromatic couplers during the synthesis, rather than synthesizing a series of individual triarylmethane leuco compounds with narrow distributions.

Unless otherwise noted, all component or composition levels are in reference to the active portion of that component or composition, and are exclusive of impurities, for example, residual solvents or by-products, which may be present in commercially available sources of such components or compositions.

All percentages and ratios are calculated by weight unless otherwise indicated. All percentages and ratios are calculated based on the total composition unless otherwise indicated.

In one aspect, the molar extinction coefficient of said second colored state at the maximum absorbance in the wavelength in the range 200 to 1,000 nm (more preferably 400 to 750 nm) is preferably at least five times, more preferably 10 times, even more preferably 25 times, most preferably at least 50 times the molar extinction coefficient of said first color state at the wavelength of the maximum absorbance of the second colored state. Preferably, the molar extinction coefficient of said second colored state at the maximum absorbance in the wavelength in the range 200 to 1,000 nm (more preferably 400 to 750 nm) is at least five times, preferably 10 times, even more preferably 25 times, most preferably at least 50 times the maximum molar extinction coefficient of said first color state in the corresponding wavelength range. An ordinarily skilled artisan will realize that these ratios may be much higher. For example, the first color state may have a maximum molar extinction coefficient in the wavelength range from 400 to 750 nm of as little as 10 M^cm ¹ , and the second colored state may have a maximum molar extinction coefficient in the wavelength range from 400 to 750 nm of as much as 80,000 M^cm ^"1 or more, in which case the ratio of the extinction coefficients would be 8,000: 1 or more.

In one aspect, the maximum molar extinction coefficient of said first color state at a wavelength in the range 400 to 750 nm is less than 1000 M^cm ^"1 , and the maximum molar extinction coefficient of said second colored state at a wavelength in the range 400 to 750 nm is more than 5,000 M ^{' 1} , preferably more than 10,000, 25,000, 50,000 or even 100,000 M ^{' 1} . A skilled artisan will recognize and appreciate that a polymer comprising more than one leuco moiety may have a significantly higher maximum molar extinction coefficient in the first color state (e.g., due to the additive effect of a multiplicity of leuco moieties or the presence of one or more leuco moieties converted to the second colored state).

The present invention relates to a class of leuco colorants that may be useful for use in laundry care compositions, such as liquid laundry detergent, to provide a blue hue to whiten textile substrates. Leuco colorants are compounds that are essentially colorless or only lightly colored but are capable of developing an intense color upon activation. One advantage of using leuco compounds in laundry care compositions is that such compounds, being colorless until activated, allow the laundry care composition to exhibit its own color. The leuco colorant generally does not alter the primary color of the laundry care composition. Thus, manufacturers of such compositions can formulate a color that is most attractive to consumers without concern for added ingredients, such as bluing agents, affecting the final color value of the composition.

As noted above, in a first embodiment, the invention provides a composition comprising a plurality of triarylmethane leuco molecules. Each triarylmethane leuco molecule comprises a first aryl moiety, a second aryl moiety, and a third aryl moiety. The first aryl moiety comprises a first alkyleneoxy moiety bonded thereto, and the second aryl moiety comprises a second alkyleneoxy moiety bonded thereto. The alkyleneoxy moieties can be bound to first and second aryl moieties at any suitable position of the aryl moiety and through any suitable linking group. For example, when the first and second aryl moieties are phenyl, the alkyleneoxy moieties can be bonded to the phenyl moieties at either the meta position or the para position relative to the bond to the central carbon atom of the triarylmethane leuco molecule. Preferably, the alkyleneoxy moieties are bonded to the phenyl moieties at the para position relative to the bond to the central carbon atom of the triarylmethane leuco molecule. Further, the alkyleneoxy moieties can be bonded to the aryl moieties through, for example, an oxygen atom or a nitrogen atom serving as a linking group. When the alkyleneoxy moiety is bonded to a nitrogen atom as a linking group, the nitrogen atom can be either a secondary nitrogen atom (i.e., having one hydrogen atom bonded thereto in addition to the aryl moiety and the alkyleneoxy moiety) or a tertiary nitrogen atom (i.e., having the aryl moiety and the alkyleneoxy moiety bonded thereto along with an additional organyl group). When the linking group is a nitrogen atom, the nitrogen atom preferably is bonded to the aryl moiety and to two alkyleneoxy groups that together form the alkyleneoxy moiety described above.

The first and second alkyleneoxy moieties of each triarylmethane leuco molecule have a mass that is dependent upon the type and/or number of alkylene oxide groups present in the moiety. Further, the number of alkylene oxide groups present in each of the alkyleneoxy moieties can vary from triarylmethane leuco molecule to triarylmethane leuco molecule. For example, the first alkyleneoxy moiety of one molecule may contain three ethylene oxide groups, and the first alkyleneoxy moiety of another molecule may contain four ethylene oxide groups. Generally, for a given population of triarylmethane leuco molecules, the number of alkylene oxide groups present in the alkyleneoxy moieties (i.e., the first alkyleneoxy moieties and the second alkyleneoxy moieties) follows a Poisson distribution. Thus, in a composition containing a plurality of triarylmethane leuco molecules, the molecules will have a mass distribution for the masses of the first alkyleneoxy moieties (a "first mass distribution"), and the molecules will have a mass distribution for the masses of the second alkyleneoxy moieties (a "second mass distribution"). Each of these distributions (i.e., the first mass distribution and the second mass distribution) has a maximum.

Preferably, the maximum of the first mass distribution (i.e., the distribution for the masses of the first alkyleneoxy moieties) is different from the maximum of the second mass distribution (i.e., the distribution for the masses of the second alkyleneoxy moieties). More preferably, the difference between the maximum of the first mass distribution and the maximum of the second mass distribution is 44 Daltons or more. In another preferred aspect, the difference between the maximum of the first mass distribution and the maximum of the second mass distribution is 58 Daltons or more. In another preferred aspect, the difference between the maximum of the first mass distribution and the maximum of the second mass distribution is about 200 Daltons more preferably about 220 Daltons or more.

The aromatic aldehyde, the first alkyleneoxy aryl compound, and the second alkyleneoxy aryl compound can be reacted in any suitable relative amounts. Typically, the compounds are reacted in a ratio of one molar equivalent of aromatic aldehyde to a combined total of two molar equivalents of the first alkyleneoxy aryl compound and the second alkyleneoxy aryl compound. The first alkyleneoxy aryl compound and the second alkyleneoxy aryl compound can be used in any suitable ratio. The relative amounts of the first alkyleneoxy aryl compound and the second alkyleneoxy aryl compound can be varied as desired to produce a triarylmethane leuco compound (or a composition containing such triarylmethane leuco compounds) exhibiting the desired distribution of aryl moieties (i.e., aryl moieties derived from the first alkyleneoxy aryl compound and aryl moieties derived from the second alkyleneoxy aryl compound). For example, the first alkyleneoxy aryl compound and the second alkyleneoxy aryl compound can be used in equimolar amounts. In such an embodiment, the method would produce a composition containing (1) approximately 25 mol.% of triarylmethane leuco compounds comprising one aryl moiety from the aromatic aldehyde and two aryl moieties from the first alkyleneoxy aryl compound, (2) approximately 50 mol.% of triarylmethane leuco compounds comprising one aryl moiety from the aromatic aldehyde, one aryl moiety from the first alkyleneoxy compound, and one aryl moiety from the second alkyleneoxy compound, and (3) approximately 25 mol.% of triarylmethane leuco compounds comprising one aryl moiety from the aromatic aldehyde and two aryl moieties from the second alkyleneoxy aryl compound. The relative amounts of these three groups of compounds contained in the composition will change as the relative amounts of the first and second alkyleneoxy compounds are varied. For example, using a mixture containing more of the second alkyleneoxy compound will increase the amount of triarylmethane leuco compounds comprising one aryl moiety from the aromatic aldehyde and two aryl moieties from the second alkyleneoxy aryl compound, while decreasing the amount of the other two triarylmethane leuco compounds. In one aspect, the first alkyleneoxy aryl compound and the second alkyleneoxy aryl compound can be used in a molar ratio of about 1:9 to 9: 1, about 1:4 to about 4: 1, about 3:7 to about 7:3, about 2:3 to about 3:2, or about 1: 1.

The leuco compounds and compositions described above are believed to be suitable for use in the treatment of textile materials, such as in domestic laundering processes. In particular, it is believed that the leuco compounds will deposit onto the fibers of the textile material due to the nature of the leuco compound. Further, once deposited onto the textile material, the leuco compound can be converted to a colored compound through the application of the appropriate chemical or physical triggers that will convert the leuco compound to its colored form. For example, the leuco compound can be converted to its colored form upon oxidation of the leuco compound to the oxidized compound. By selecting the proper leuco moiety, the leuco compound can be designed to impart a desired hue to the textile material as the leuco compound is converted to its colored form. For example, a leuco compound that exhibits a blue hue upon conversion to its colored form can be used to counteract the yellowing of the textile material to normally occurs due to the passage of time and/or repeated launderings. Thus, in other embodiments, the invention provides laundry care compositions comprising the above-described leuco compound and domestic methods for treating a textile material (e.g., methods for washing an article of laundry or clothing).

Preferably the leuco compound, when converted to its second color state, gives a hue to the cloth with a relative hue angle of 210 to 345, or even a relative hue angle of 240 to 320, or even a relative hue angle of 250 to 300 (e.g., 250 to 290). The relative hue angle can be determined by any suitable method as known in the art. However, preferably it may be determined as described in further detail herein with respect to deposition of the leuco entity on cotton relative to cotton absent any leuco entity. As noted above, in a second embodiment, the invention provides a laundry care composition comprising a laundry care ingredient and a leuco composition as described herein. The laundry care composition can comprise any suitable leuco composition or combination of leuco compositions as described herein. The laundry care composition can comprise any suitable laundry care ingredient. Laundry care ingredients suitable for use in the invention are described in detail below.
