Abstract
The present invention provides a treatment composition comprising a hydrophobic dye.
Claims26
A laundry method of simultaneously washing and whitening a polyester-containing textile garment, the method comprising:
- (a) treating under normal domestic wash conditions the textile garment with an aqueous solution comprising:
- (i) from 1 ppb to 5 ppm of a hydrophobic dye, which is an azo dye, wherein the hydrophobic dye, when deposited onto the textile garment, provides a blue or violet shade to the garment that imparts a shading whiteness benefit thereto, and
- (ii) from 0.2 g/L to 3 g/L of a detersive surfactant, which is a mixture of at least one anionic surfactant and at least one nonionic surfactant, wherein the nonionic surfactant is present in an amount greater than 10 wt % of the total surfactant;
- and
- (b) rinsing and drying the textile garment,
- wherein (a) provides a simultaneous washing and shading whiteness benefit to the polyester-containing textile garment.

A laundry treatment composition for simultaneously washing and whitening a polyester-containing textile garment under normal domestic wash conditions, comprising:
- (i) between 0.0001 to 0.1 wt % of a hydrophobic dye, which is an azo dye, wherein the hydrophobic dye, when deposited onto the textile garment, provides a blue or violet shade to the garment that imparts a shading whiteness benefit thereto, and
- (ii) between 2 and 60 wt % of a detersive surfactant, wherein the detersive surfactant is a mixture of at least one anionic surfactant and at least one nonionic surfactant, and
- (iii) at least one enzyme.
