DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to heavy duty laundry detergent compositions, in either liquid or granular form, which contain certain types of polyamide-polyamine materials to impart appearance benefits to fabrics and textiles laundered in washing solutions formed from such compositions.
BACKGROUND OF THE INVENTION
It is, of course, 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 appearance of such fabrics and textiles.
Deterioration of fabric 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 "prills" which are visible on the surface of fabrics and diminish the appearance of newness of the fabric. Further, repeated laundering of fabrics and textiles, especially with bleach-containing laundry products, can remove dye from fabrics and textiles and impart a faded, worn out appearance as a result of diminished color intensity, and in many cases, as a result of changes in hues or shades of color.
Given the foregoing, there is clearly an ongoing need to identify materials which could be added to laundry detergent products that would associate themselves with the fibers of the fabrics and textiles laundered using such detergent products and thereby reduce or minimize the tendency of the laundered fabric/textiles to deteriorate in appearance. Any such detergent product additive material should, of course, be able to benefit fabric appearance without unduly interfering with the ability of the laundry detergent to perform its fabric cleaning function. The present invention is directed to detergent compositions containing certain types of polyamide-polyamine materials that perform in this desired manner.
SUMMARY OF THE INVENTION
The laundry detergent compositions herein comprise from about 1% to 80% by weight of a detersive surfactant, from about 0.1% to 80% by weight of an organic or inorganic detergency builder and from about 0.1% to 8% by weight of certain types of polyamide-polyamine fabric treatment agents. The detersive surfactant and detergency builder materials can be any of those useful in conventional laundry detergent products. The polyamide-polyamine materials are those which are comprised of repeating amido-amine units which may be substituted and/or derivatized as shown in the general Structural Formula No. I set forth hereinafter in the "Detailed Description of the Invention" section.
Particularly preferred polyamide-polyamine materials for use in the detergent and fabric treatment compositons herein comprise the reaction products of epichlorohydrin with polyamide-polyamines formed from adipic acid and diethylenetriamine. Such materials are commercially available under the tradename Kymene.RTM..
In its method aspect, the present invention relates to the laundering or treating of fabrics and textiles in aqueous washing or treating solutions formed from effective amounts of the detergent compositions described herein, or formed from the individual components of such compositions. Laundering of fabrics and textiles in such washing solutions, followed by rinsing and drying, imparts fabric appearance benefits to the fabric and textile articles so treated. Such benefits can include improved overall appearance, prills/fuzz reduction, and antifading.
DETAILED DESCRIPTION OF THE INVENTION
As noted, the laundry detergent compositions of the present invention essentially contain detersive surfactant, detergent builder and certain polya
