Laundry care composition comprising a whitening agents for cellulosic substrates

摘要

This invention 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, for cellulosic substrates. The whitening agents are comprised of at least two components: at least one chromophore component comprising triphenylmethane colorant, 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 0.5 .
