ABSTRACT:
FIELD OF THE INVENTION
The present application relates to rinse-added fabric care compositions which comprise one or more crosslinked and/or grafted polyamines which provide enhanced fabric appearance benefits. The crosslinked and/or grafted polyamines of the present invention which mitigate fabric damage and improve fabric appearance may be combined with fabric softener actives compositions which mitigate fabric damage.
BACKGROUND OF THE INVENTION
The domestic treatment of fabric is a problem known in the art to the formulator of laundry compositions. Hence, It is well known that alternating cycles of using and laundering fabrics and textiles, such as articles of worn clothing and apparel, will inevitably adversely affect the appearance and integrity of the fabric and textile items so used and laundered. Fabrics and textiles simply wear out over time and with use. Laundering of fabrics and textiles is necessary to remove soils and stains which accumulate therein and thereon during ordinary use. However, the laundering operation itself, over many cycles, can accentuate and contribute to the deterioration of the integrity and the appearance of such fabrics and textiles.
Deterioration of fabric integrity and appearance can manifest itself in several ways. Short fibers are dislodged from woven and knit fabric/textile structures by the mechanical action of laundering. These dislodged fibers may form lint, fuzz or “pills” which are visible on the surface of fabrics and diminish the appearance of newness of the fabric. Such a problem of fabric abrasion is even more acute after multiwash cycles.
There exists a long felt need for compositions which provide fabric with protection against damage done due to fabric abrasion. In addition, there is a long felt need to provide compositions which provide a remedy for fabric abrasion damage.
SUMMARY OF THE INVENTION
The present invention meets the aforementioned needs in that it has been surprisingly discovered that high molecular weight modified polyamine compounds, preferably compounds formed by the reaction of grafted or ungrafted and/or modified or unmodified polyamines with a crosslinking agent wherein said modified polyamine compounds have a molecular weight of from about 1,000 daltons, preferably from about 10,000 daltons to about 10 million daltons, preferably to about 2.5 million daltons, are suitable for use in rinse-added fabric care compositions wherein said modified polyamines comprise a fabric enhancement system which provides fabric appearance benefits inter aria mitigation of fabric dye damage via bleaching agents, prevention of fabric mechanical damage.
A first aspect of the present invention relates to rinse-added fabric enhancement or fabric care compositions comprising:
a) from about 0.0 1% by weight, of a fabric enhancement system, said fabric enhancement system comprising one or more modified polyamine compounds, said modified polyamine compounds are selected from:
i) (PA)

;
ii) (PA)
w
(L)
z
;
iii) [(PA)
w

y
[L]
z
; and
iv) mixtures thereof;
wherein PA is a grafted or non-grafted, modified or unmodified polyamine backbone unit, T is an amide-forming polycarboxylic acid crosslinking unit, and L is a non-amide forming crosslinking unit; provided that for compounds of type (i) and (iii) the indices w and x have values such that the ratio of w to x is from 0.8:1 to 1.5:1; for compounds of type (ii) the indices w and z have values such that said modified polyamine compound comprises from about 0.05, preferably from about 0.3 to 2 parts by weight of said L unit; for compounds of type (iii) the indices y and z have values such that said modified polyamine compound comprises from about 0.05, preferably from about 0.3 to 2 parts by weight of said L unit; and
b) the balance carriers and adjunct ingredients.
A second aspect of the present invention relates to fabric care compositions comprising:
a) from about 0.01%, preferably from about 0.1% to about 20%, preferably to about 10% by weight, of a modified polyamine compound according to the present invention;
b) optionally from about 0.01% by weight, of a fabric abrasion polymer comprising:
i) at least one monomeric unit comprising an amide moiety;
ii) at least one monomeric unit comprising an N-oxide moiety;
iii) and mixtures thereof;
c) optionally from about 1%, preferably from about 10%, more preferably from about 20% to about 80%, preferably to about 60%, more preferably to about 45% by weight, of a fabric softening active;
d) optionally less than about 15% by weight, of a principal solvent, preferably said principal solvent has a ClogP of from about 0.15 to about 1;
e) optionally from about 0.001% to about 90% by weight, of one or more dye fixing agents;
g) optionally from about 0.01% to about 50% by weight, of one or more cellulose reactive dye fixing agents;
g) optionally from about 0.01% to about 15% by weight, of a chlorine scavenger;
h) optionally about 0.005% to about 1% by weight, of one or more crystal growth inhibitors;
i) optionally from about 1% to about 12% by weight, of one or more liquid carriers;
j) optionally from about 0.001% to about 1% by weight, of an enzyme;
k) optionally from about 0.01% to about 8% by weight, of a polyolefin emulsion or suspension;
l) optionally from about 0.01% to about 0.2% by weight, of a stabilizer;
m) optionally from about 0.01% by weight, of one or more linear or cyclic polyamines which provide bleach protection; and
n) the balance carrier and adjunct ingredients.
The present invention also relates to a method for providing reduced fabric abrasion to fabric, said method comprising the step of contacting said fabric with a composition which comprises from about 0.01% by weight, of the herein described modified polyamine fabric enhancement system.
A further aspect of the present invention provides a method for enhancing the color fidelity of fabric while reducing the damage to fabric due to the interaction of laundry adjunct ingredients and damage due to mechanical wear. This method comprises the step of contacting an article of fabric with the compositions of the present invention in an aqueous solution.
The present invention further provides laundry pre-soak compositions which are used to pre-treat fabric which have not been previously treated with a composition of the present invention. The disclosed pre-treatment compositions provide fabric and fabric color protection though the wash to the treated articles.
These and other objects, features and advantages will become apparent to those of ordinary skill in the art from a reading of the following detailed description and the appended claims. All percentages, ratios and proportions herein are by weight, unless otherwise specified. All temperatures are in degrees Celsius (° C.) unless otherwise specified. All documents cited are in relevant part, incorporated herein by reference.
DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to fabric enhancement compositions which comprise from about 0.01%, preferably from about 0.1%, more preferably from 0.25%, most preferably from about 0.5% to about 20%, preferably to about 10%, more preferably to about 5% by weight, of a fabric enhancement system. Said fabric enhancement system is comprised of one or more modified polyamine compounds. The fabric care and/or fabric enhancement compositions may take any form, for example, solids (i.e., powders, granules, extrudates), gels, thixotropic liquids, liquids (i.e., dispersions, isotropic solutions), preferably the rinse-added fabric conditioning compositions take the form of liquid dispersions or isotropic liquids.
For the purposes of the present invention the terms “fabric enhancement” and “fabric care” are used interchangeable throughout the present specification and stand equally well for one another. Fabric enhancement/fabric care is achieved when the properties inter alia color, fiber integrity of the garment are conserved. An additional benefit realized by the use of the compositions of the present invention is a reversion of much of
