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

Bisurea gelling agents that impart a number of unexpected benefits within various gelled formulations and exhibit great versatility in terms of gelling capabilities for many types of solvents are provided. Such gelling agents should include pendant groups, such as sterically hindering alkyl groups attached to polyoxyalkylenated moieties that allow the gelling agent to be compatible with the target liquid system at elevated temperatures, while controlling and/or limiting the network formation and strength during the cooling cycle. Alternatively, novel gelling agents having two urea groups but that are asymmetrical in configuration have been produced in order to provide the same control in temperature, compatibility, and efficiency. Final gelled formulations, such as antiperspirant sticks and other like consumer items, are provided as well within this invention.

Bisurea gelling agents and compositions

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.

Whitening agents for cellulosic subtrates

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