Description

COMPOSITIONS DETERGENTS FOR LAUNDRY WITH POLYAMIDE-POLYAMINES TO PROVIDE BENEFITS OF APPEARANCE TO FABRICS WASHED WITH THE SAME TECHNICAL FIELD The present invention relates to heavy-duty laundry detergent compositions, in liquid or granular form, which contain certain types of polyamide-poiamymine materials to impart the appearance benefits to washed fabrics and textiles in washing solutions formed from said compositions .

BACKGROUND OF THE INVENTION It is clearly known that alternating cycles of use and laundry of fabrics and textiles, such as worn clothing and clothing items, will inevitably adversely affect the appearance and integrity of the fabric and textile articles used and washed in this way. Fabrics and textiles simply wear out over time and with use. The laundry of fabrics and textiles is necessary to remove the dirt and stains that accumulate in and during the ordinary use of them. However, the laundry operation itself, with several cycles, can accentuate and contribute to the deterioration of the appearance of said fabrics and textiles.

The deterioration of the appearance of the fabric can manifest itself in several ways. The short fibers are dislodged from the fabric / textile structures woven and interlaced by the mechanical laundry action. Said dislodged fibers can form lint, lint or "pellets" that are visible on the surface of fabrics and diminish the novelty appearance of the fabric. In addition, repeated laundry of fabrics and textiles, especially laundry products containing bleach, can remove pigment from fabrics and textiles and impart a faded, worn appearance as a result of diminished color intensity and, in several cases, as a result of changes in color tints or shades. Due to the above, there is clearly a need to identify the materials that can be added to the detergent laundry products that can be associated with the fibers of fabrics and textiles washed using said detergent products and therefore reduce or minimize the tendency of the fabric / washed textiles to deteriorate the appearance. Any detergent product additive material must, of course, be able to benefit the appearance of the fabric without unduly interfering with the laundry detergent capacity of carrying out its fabric cleaning function. The present invention relates to detergent compositions containing certain types of polyamide-polyamine materials that act in that desired manner.

BRIEF DESCRIPTION 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 and inorganic builder and from about 0.1% to 8% by weight. weight of certain types of polyamide-polyamine fabric treatment agents. The detersive surfactant and builders can be any material useful in conventional laundry detergent products. The polyamide-polyamine materials are those that are comprised of repeating amido-amine units that can be substituted and / or derived as shown in general structural formula No. 1 described later in the "detailed description of the invention". Particularly preferred poleamide-poleamine materials for use in the detergent and fabric treatment compositions herein comprise the reaction products of epichlorohydrin with polyamide-polyamines formed of adipic acid and diethylenetriamine. Such materials are commercially available under the trade name Kymene®. In its aspect of method, the present invention relates to the laundry or treatment of fabrics and textiles in aqueous washing or treatment solutions formed of effective amounts of the detergent compositions described herein., or formed of the individual components of said compositions. The laundry of fabrics and textiles in said washing solutions, followed by rinsing and drying, imparts the appearance benefits of the fabric to cloth and textile articles treated in this way. Such benefits may include improved overall appearance, pellet / lint reduction and anti-fading.

DETAILED DESCRIPTION OF THE INVENTION As noted, the laundry detergent compositions of the present invention essentially contain detersive surfactant, builder, and certain polyamide-polyamine fabric treatment agents that serve to promote the appearance of the fabric with the use of the detergent compositions for the washing of fabrics and textiles.

E) Preparation of the detergent composition The detergent compositions according to the present invention may be in liquid, paste or granular forms. Said compositions can be prepared by combining the essential and optional components in the necessary concentrations in any suitable order or by conventional means. The granulated compositions, for example, they are generally made by combining the ingredients of granular base (ie surfactant, builders, water, etc.) as slurry, dissected by spraying the resulting sludge at a low level of residual moisture (5-12). %). The remaining dry ingredients can be mixed in the form of granulated powder with the spray-dried granules in a rotating mixing cylinder in the liquid ingredients (ie, aqueous suspensions of the polyamide-polyamine essential, as enzymes, binders and perfumes can be sprayed in the resulting granules to form the finished detergent composition The granulated compositions according to the present invention can also be found in "compact form" ie they can have a relatively higher density than conventional granular detergents, ie from 550 to 950 g / l In this case the granular detergent compositions according to the present invention will contain a lower amount of "inorganic filler salt", compared to conventional granular detergents; typical filler salts are salts of alkaline terry moistens of sulfates and chlorines, typically sodium sulfate; "compact" detergents typically comprising no more than 10% filler salt. Liquid detergent compositions can be prepared by mixing the essential and optional ingredients thereof in any desired order to provide compositions containing components in the necessary concentrations.

Contact with the fabrics with the wash solution will generally occur under agitating conditions although the compositions of the present invention can also be used to form aqueous rinseless solutions for cleaning and treating fabrics. The stirring of preferences is provided in a washing machine for good cleaning. Preferably washing is followed by drying the wet cloth in a conventional laundry drying. An effective amount of the liquid or granular detergent composition in the aqueous wash solution in the washing machine is preferably from about 500 to about 7000 ppm, most preferably from about 1000 to about 3000 ppm.
