This invention relates to novel whitening agents for cellulosic substrates. The whitening agents are comprised of at least two components: at least one chromophore component and at least one polymeric component. Suitable chromophore components generally fluoresce blue, red, violet, or purple color when exposed to ultraviolet light, or they may absorb light to reflect these same shades. The whitening agents are further characterized by having a dispersion component value of the Hansen Solubility Parameter of less than or equal to about 17 MPa. This invention also relates to laundry care compositions including but not limited to liquid and/or powder laundry detergent formulations and rinse added fabric softening (RAFS) compositions that comprise such whitening agents.

Whitening agents for cellulosic substrates

The present invention relates to thiazolium dyes, laundry care compositions comprising one or more thiazolium dyes, processes of making such dyes and laundry care compositions and methods of using same. The dyes, compositions and methods of the present invention are advantageous in providing improved hueing of fabric, including whitening of white fabric, while avoiding significant build up of bluing dyes on the fabric.

Laundry care compositions with thiazolium dye

Whitening agents for cellulosic subtrates

Fabric conditioning compositions comprising a fabric care active and a hueing dye, wherein the hueing dye exhibits a hueing efficiency of at least about 20 according to the Hueing Efficiency Test method; and a Wash Removal Value from about 50% to about 98%, are useful in mitigating the discoloration of white and other light colored fabrics.

Fabric care compositions comprising hueing dye

Laundry detergent compositions comprise (a) surfactant, and (b) a hueing dye, wherein the hueing dye exhibits a hueing efficiency of at least 10 and a wash removal value in the range of from about 30% to about 85%.

Laundry detergent compositions with efficient hueing dye

Laundry detergent compositions comprise (a) surfactant, and (b) a hueing dye selected from triarylmethane blue and violet basic dyes, methine blue and violet basic dyes, anthraquinone blue and violet basic dyes, azo dyes basic blue 16, basic blue 65, basic blue 66 basic blue 67, basic blue 71, basic blue 159, basic violet 19, basic violet 35, basic violet 38, basic violet 48, oxazine dyes, basic blue 3, basic blue 75, basic blue 95, basic blue 122, basic blue 124, basic blue 141, Nile blue A and xanthene dye basic violet 10, and mixtures thereof.
