17

wherein R 1, R 2 and R 3 they can be any hydrocarbyl unit (for the purposes of present invention the expression "hydrocarbyl" does not include hydrogen atoms alone). The N-oxide unit can be part of a polymer, such as a polyamine, that is, the main chain of polyalkyleneamine, or it can also be part of a pendant group attached to the main polymer chain. An example of a polymer comprising an N-oxide unit as part of the main chain Polymeric is polyethyleneimine N-oxide. Non-limiting examples of groups that may comprise an N-oxide moiety include those N-oxides of certain heterocycles, among others pyridine, pyrrole, imidazole, pyrazole, pyrazine, pyrimidine, pyridazine, piperidine, pyrrolidine, pyrrolidone, azolidine and morpholine.

Polymers comprising N-oxide of the present invention will preferably have a relationship between N-oxidized amine nitrogen and non-amine nitrogen oxidized from about 1: 0 to about 1: 2, preferably at about 1: 1, more preferably at approximately 3: 1. The amount of N-oxide units can be adjusted by the formulator. For example, the formulator can copolymerize monomers comprising N-oxide with monomers that do not comprise N-oxide to achieve the desired ratio between units amino N-oxide and amino units without N-oxide, or the formulator can monitor the level of polymer oxidation during preparation. The amine oxide unit of the polyamine N-oxides of the present invention has a Pk a less than or equal to 10, preferably less than or equal to 7, more preferably less than or equal to 6. The average molecular weight of polymers comprising N-oxide that provide an advantage of transfer inhibition of dyestuffs for fabric abrasion reducing polymers is 100,000 daltons, more preferably about 160,000 daltons to approximately 6,000,000 daltons, preferably at about 2,000,000 daltons, more preferably at approximately 360,000 daltons.

Polymers comprising amide units and N-oxide units

Another example of polymers that are polymers tissue abrasion reducers with advantage of inhibition of dye transfer are the polymers that comprise the amide units and the N-oxide units described above in the present memory Non-limiting examples include copolymers of two monomers wherein the first monomer comprises an amide unit and the second monomer comprises an N-oxide unit. In addition, the block oligomers or polymers comprising these units are can bind to form mixed polymers of amide / N-oxide. Without However, the resulting polymers must retain the requirements of water solubility described above herein.

Molecular weight

For all polymers of the invention described above, it is most preferred that they have a weight molecular in the range described above herein memory. This interval is typically greater than the interval of polymers that only have advantages of inhibition of dye transfer In fact, the highest molecular weight of abrasion reducing polymers provide a reduction in the abrasion of the tissues that typically occurs after of the treatment, for example during the use of the garment, especially in a subsequent washing procedure. Without pretending impose any theory, it is believed that the high molecular weight allows the deposition of the polymer on the surface of the tissue and provides sufficient efficiency so that the polymer is capable of remaining in the tissue during subsequent use and washing posterior tissue. In addition, it is believed that for a load density determined, increasing the molecular weight will increase the permanence of the polymer on the tissue surface. So ideal the balance between charge density and molecular weight will provide a sufficient deposition rate on the tissue surface and sufficient tissue attraction during subsequent wash cycles. The increase in molecular weight is considered preferable to the increase of the density of load since allows a wider choice of materials that can provide the desired advantage and avoid the negative impact that it may occur to increase the density of load, among others, the attraction of dirt and debris on treated tissues. Fits emphasize, however, that a similar advantage can be predicted if load density is increased with a lower weight material molecular.

The term "dye fixing agent that reacts with cellulose" is defined herein as "a dye fixing agent that reacts with cellulose fibers when heat is applied or a heat treatment in situ or by the formulator". The dye fixing agents that react with cellulose for use in the present invention can be defined by the following test method.

Cellulose reactivity test (CRT)

Four pieces of tissue are selected that are able to release their dyes (e.g., 10 x 10 cm of woven cotton dyed with Direct Red 80). Two samples are used as the first control and second control, respectively. The two samples remaining soak for 20 minutes in an aqueous solution that contains 1% (w / w) of the dye fixing agent that reacts with Cellulose to be analyzed. The samples are removed and dried meticulously. One of the treated and dried samples meticulously passed ten times through an iron roller It adjusts to the "linen fabric" temperature position. The first control sample is also passed ten times through An iron roller in the same temperature position.

The four samples (the two control samples and the two treated samples, one of which has been treated with the ironing roller) are washed separately in containers Launder-O-Meter in conditions typical with a commercial detergent at the recommended dosage for ½ h at 60 ° C, then rinse thoroughly with 200 ml of Cold water 4 times, and then dried on a rope.

Next, the inalterability of the color comparing the values of a new sample without dealing with the Four samples submitted to the test. DE values, the difference of calculated color, they are defined in ASTM D2244. In general, the DE values refer to the magnitude and direction of the difference between two psychophysical color stimuli defined by values triestimulos, or by chromaticity coordinates and factor of luminance, calculated using an established set of equations of color differences defined in the opposite CIE color space 1976 CIELAB, the opposite color space Hunter, the color space Friele-Mac Adam-Chickering or Any equivalent color space. For the purpose of the present invention, the lower the DE value of a sample, the more the sample resembles the untested sample and the greater the color fastness benefit.

As the essay refers to the selection of a dye fixing agent that reacts with cellulose, if the DE value of the sample treated in the ironing stage is better than that of the two control samples, the candidate is a fixing agent of dyes that reacts with cellulose for the purpose of invention.

Typically dye fixing agents which react with cellulose are compounds that contain a residue cellulose reagent, non-limiting examples of which include halogen-triazines, vinylsulfones, derivatives of epichlorohydrin, hydroxyethylene urea derivatives, products of condensation of formaldehyde, polycarboxylates, glyoxal and derivatives of glutaraldehyde and mixtures thereof. Other examples can be find in "Textile Processing and Properties", Tyrone L. Vigo, on pages 120 to 121, Elsevier (1997), which describe specific electrophilic groups and their corresponding affinity to cellulose.

Crystal growth inhibition assay (CGIT)

The suitability of a material to serve as a crystalline growth inhibitor according to the present invention can be determined by in vitro evaluation of certain inorganic microcrystals. The procedure of Nancollas et al., Described in "Calcium Phosphate Nucleation and Growth in Solution", Prog. Crystal Growth Charact ., Vol. 3, 77-102, (1980), incorporated herein by reference, is a method that is suitable for assessing the inhibition of crystalline growth of compounds. The lower graph is an example of a graph that indicates the delay time (t-lag) in the formation of a hypothetical crystal growth inhibitor crystal.

18

Main solvent

The compositions of the present invention, preferably the isotropic liquid embodiments of the they can also optionally comprise a solvent principal. The level of main solvent present in the compositions of the present invention is typically less than about 95%, preferably less than about 50%, more preferably less than about 25% and with maximum preference less than about 15%, by weight. Some embodiments of isotropic liquid of the present invention can do not understand principal solvent but may instead have a suitable nonionic surfactant.

The main solvents of this invention are mainly used to obtain compositions liquids with sufficient transparency and viscosity. Solvents principals must also be selected to minimize the odor impact of the solvent on the composition. For example, him Isopropyl alcohol is not an effective main solvent since it does not serves to produce a composition that has a suitable viscosity. Isopropanol is not a main solvent either suitable because it has a relatively strong smell.

The main solvents are also select for their ability to provide compositions stable at low temperature, preferably the compositions that comprise suitable main solvents remain transparent up to about 4 ° C and have the ability to fully recover its transparency when stored until temperatures of approximately 7 ° C.

The main solvents according to the present invention are selected according to their distribution coefficient octanol / water (P). The octanol / water partition coefficient is a measure of the relationship between the concentrations of a given Main solvent in octanol and in water in equilibrium. The distribution coefficients are expressed and recorded conveniently as its logarithm in base 10 or logP.

The logP values of many types of main solvents; for example, the basis of Ponmona92 data, marketed by Daylight Chemical Information Systems, Inc. (Daylight CIS), contains many of these values together with references to the original bibliography.

However, logP values are more conveniently calculated using the "CLOGP" program, also marketed by Daylight CIS. This program also includes experimental logP values if available in the Pomona92 database. The "calculated logP" (ClogP) is determined by the Hansch and Leo fragment method (A. Leo, Comprehensive Medicinal Chemistry, vol. 4, C. Hansch, PG Sammens, JB Taylor and CA Ransden, Eds., P. 295, Pergamon Press, 1990, incorporated by reference herein). The molecular fragment method is based on the chemical structure of each HR type and takes into account the number and type of atoms, the connectivity of the atom and the chemical bond. ClogP values are the most reliable and widely used estimates for octanol / water distribution. The person skilled in the art will understand that experimental logP values can also be used. Experimental logP values represent a less preferred embodiment of the invention. If experimental logP values are used, the one-hour logP values are preferred. Other methods that can be used to calculate the ClogP value include, e.g. eg, the Crippen fragmentation method, as described in J. Chem. Inf. Comput. Sci ., 27a, 21 (1987); the Viswanadhan fragmentation method, as described in J. Chem. Inf. Comput. Sci ., 29, 163 (1989); and the Broto method, as described in Eur. J. Med. Chem. - Chim. Theor ., 19, 71 (1984).

The main solvents suitable for your use in the present invention are selected from those that have a ClogP from about 0.15 to about 1, preferably from about 0.15 to about 0.64, more preferably from about 0.25 to about 0.62 and with maximum preference of about 0.4 to about 0.6. Preferably the main solvent is at least to some extent an asymmetric molecule that preferably has a melting point or solidification that allows the main solvent to be liquid at room temperature or at temperatures near it. The Low molecular weight main solvents may be desirable In some embodiments. The most preferred molecules are the very asymmetric

However, in the laundry compositions of the present invention may use any clay or dirt dispersing agent or any suitable anti-redeposition agent.

Electrolyte

Fabric softener embodiments of the compositions of the present invention, especially the softening compositions of isotropic liquid tissues transparent, you can also optionally, but preferably, comprise one or more electrolytes to control the stability of phase, viscosity and / or transparency. For example, the presence of certain electrolytes, such as calcium chloride or magnesium chloride, can be key to guarantee the transparency and the initial low viscosity of the product or can affect the dilution viscosity of liquid embodiments, especially liquid isotropic embodiments. Without pretending impose limiting theories and wishing only to provide a example of a circumstance where the formulator must guarantee an adequate dilution viscosity, the following is included Example: In the rinse phase of laundry operations liquid fabric softener compositions can be introduced Isotropic or non-isotropic through a manufactured item designed to dispense a measured amount of said composition. From Typically the manufactured item is a dispenser that provides the active substance softener only during the cycle of cleared up. These dispensers are typically designed to allow an amount of water equal to the volume of composition fabric softener enters the dispenser to ensure a supply Complete of the softening composition. An electrolyte can be added to the compositions of the present invention to ensure the phase stability and prevent the diluted softener composition "gel" or suffer an undesirable increase in viscosity or unacceptable. By avoiding gelation or formation of a solution "swollen" high viscosity is guaranteed a supply careful of the softening composition.

However, the person skilled in the art of fabric softening compositions will recognize that the level of electrolyte is also affected by other factors, such as by example the type of active substance fabric softener, the amount of main solvent and level or type of surfactant nonionic For example, quaternary ester amines derived from trietanol amine suitable for use as active substances Softeners in the present invention are typically manufactured so that a distribution of ammonium compounds is obtained mono-esterified quaternary, di-esterified and tri-esterified and of amine precursors. Therefore, as in this example, the variability in the distribution of mono-esters, di-esters and tri-esters and amines can lead to different levels of electrolyte. Therefore, the formulator before selecting the type and / or the electrolyte level must take into account all ingredients, namely softening active substance, non-surfactant ionic, and in the case of isotropic liquids, the type and level of main solvent, as well as the level and identity of adjuvant ingredients

A wide range of salts can be used ionizable. Examples of suitable salts are metal halides of groups IA and IIA of the periodic table of elements, by example, calcium chloride, sodium chloride, potassium bromide and Lithium chloride. Ionizable salts are especially useful during the process of mixing the ingredients to prepare the compositions of the present invention and later to obtain the desired viscosity The amount of ionizable salts used depends on the amount of active ingredients used in the compositions, being able to adjust this according to the wishes of the formulator The levels of typical salts used to control The viscosity of the composition is about 20 to approximately 10,000 parts per million (ppm), preferably of about 20 to about 5,000 ppm, of the composition.

The alkylene polyammonium salts can be incorporated into the composition to control viscosity in addition of, or instead of, the above water-soluble ionizable salts. In addition, these agents can act as eliminators, forming ion pairs with the washed anionic detergent main or rinse and that is on the tissue, and can improve softness performance. These agents can stabilize viscosity over a wider temperature range, especially at low temperatures, than electrolytes inorganic Specific examples of salts of poly (alkylene ammonium) include monohydrochloride L-lysine and dihydrochloride 1,5-diamonium-2-methylpentane.
