FIELD OF INVENTION
[0001] The present invention relates to the delivery of dyes to fabrics.
BACKGROUND
[0002] Shading dyes may be used to enhance the whiteness of garments in the laundry process.
WO2005/003276 WO2006/010472 and
WO2008/017570 (all Unilever) teaches the use of specific acid azo, anthraquinone, triphenylmethane
and azine dyes for shading garments.
WO2006/004870 WO2007/084729 (Proctor and Gamble) and co-pending
EP08150172 (Unilever) teaches the use of specific basic triphenylmethane, thiazolium, anthraquinone
and methane dyes for shading garments. The advantage of these dyes is that they deposit
in the first washes and then do not build up further on the fabrics in subsequent
washes. This prevents overshading of garments.
[0003] Wash loads typically consist of a range of fabrics made from different fibers, particularly
cotton, polyester, nylon and elastane. Elastane containing fabrics are prone to yellow
much more than other fibers due to oxidation. It would thus be desirable to have a
shading dye that build up slowly on elastane fabrics over multiple washes but not
on cotton or polyester. This would provide optimal whiteness over the lifetime of
all garments in the wash.
SUMMARY OF INVENTION
[0004] Blue or violet cationic naptholactam dyes build up slowly on elastane fabrics over
multiple washes but not on cotton or polyester when applies in domestic washing.
[0005] In one aspect the present invention provides a laundry treatment composition comprising:
- (i) from 2 to 70 wt% of a surfactant, and from 0.0001 to 0.1 wt% of a cationic blue
or violet naptholactam dye of the following structure:
wherein:
X- is a counter ion;
R1 is an optionally substituted alkyl which may form an alkylene bridge at the 1 position;
R2 is a group having at least one benzene moiety directly bound to a nitrogen atom,
wherein the benzene moiety is between 1 and 4 bonds removed from the naptholactam
and in conjugation with the naptholactam and rings A and B are optionally substituted.
[0006] In another the present invention provides a domestic method of treating a textile,
the method comprising the steps of:
- (i) treating a textile with an aqueous solution of the cationic blue or violet naptholactam,
the aqueous solution comprising from 1 ppb to 1 ppm of the cationic blue or violet
naptholactam dye, and from 0 ppb to 1 ppm of another dye or pigment selected from:
pigments, hydrophobic dyes and direct dyes; and, from 0.0 g/L to 3 g/L of a surfactant;
- (ii) optionally rinsing the textile; and, (iii) drying the textile. Prefereably, the
aqueous solution comprises 0.1 to 50 ppm of fluorescer.
