Description

COMPOSITIONS FOR THE CARE OF FABRICS FIELD OF THE INVENTION The present invention relates to compositions for the care of fabrics and more particularly to a method and a composition that have reduced formation or even do not present soapy cream on the fabrics and / or parts of the washing machine while at the same time At the same time they provide care to the colors of the fabrics treated with them.
BACKGROUND OF THE INVENTION The appearance of dyed fabrics, for example, clothes, bedding, household fabrics such as tablecloths, is one of the areas of concern for consumers. In fact, after the typical uses that the consumer gives to the fabrics such as using them, washing them, rinsing them and / or drying them in a rotary dryer, a loss in the appearance of the fabric is observed. cloth; which is at least partially due to the loss of color fidelity and color definition. Such a problem of color loss is even more acute after multiple washing cycles.
It is therefore an object of the invention to provide a composition that provides improved color care to washed fabrics. , especially after multiple washing cycles.The dye fixing components such as those described in EP462806 are suitable components for this purpose, since these components provide color care of the fabrics helping to bind the dye weakly retained by the dye. Even a new class of materials, specifically, the amino-functional polymers can also be used, in fact, they have recently found increasing use in the treatment of fabrics in order to provide care for the color of the fabrics. However, a problem currently encountered with the compositions comprising such color-fixing agents and / or amino-functional polymer is the resulting soap that is formed on the treated fabrics and / or the parts thereof. to machine washing machine. Without wishing to be bound by the theory, it is believed that the formation of the soapy cream arises from the interaction of such nitrogenous compounds, ie the amino-functional polymers and / or the dye fixing agent, with the anionic species such as the surfactants. Anionics that are washed away from the detergent, especially through multiple washing cycles. This interaction results in insoluble sticky precipitates on the fabrics and / or parts of the washing machine.
Accordingly, the formulator of a fabric care composition faces the double challenge of formulating a composition that has a reduced formation or does not even have soapy cream formation but is not detrimental to the colors of the treated fabrics. The Applicant has now discovered, surprisingly, that the problem is solved by providing a soapy reducing agent that is selected from a water-soluble cationic surfactant; a polyoxyalkylene alkylamine surfactant, and mixtures thereof, to compositions comprising a nitrogenous compound that is selected from an amino-functional polymer, a dye-fixing agent and mixtures thereof.
BRIEF DESCRIPTION OF THE INVENTION The present invention relates to a fabric care composition comprising: i) a nitrogenous compound that is selected from a polyamino functional polymer, a dye fixing agent, and mixtures thereof and ii) a reducing agent of soapy cream that is selected from a water-soluble cationic surfactant; a polyoxyalkylene alkylamine type surfactant, and mixtures thereof; with the proviso that when the only nitrogenous compound is a polyamino-functional polymer, the polymer is present in amounts greater than 1% by weight. In another aspect of the present invention, the use of surfactant is provided in a composition comprising a nitrogenous compound that is selected from a polyamino functional polymer, a dye fixing agent and mixtures thereof, to reduce or avoid the formation of soapy cream on the fabrics or on the parts of the washing machine that come into contact with the composition.
DETAILED DESCRIPTION OF THE INVENTION In accordance with one aspect of the present invention, a fabric care composition having effective and durable color care properties is provided. An essential component of the invention is a nitrogenous compound which is selected from an amino-functional polymer, a dye-fixing agent and mixtures thereof.
Amino-functional polymer The amino-functional polymer provides an advantageous care to the colors of the fabrics. The amino-functional polymers of the present invention are soluble polymers or dispersible in water. Typically, the amino-functional polymers that are used in the present invention have a molecular weight between 200 and 10 ^, preferably between 600 and 20,000, more preferred between 1000 and 10,000. These polyamines comprise base structures that can be linear or cyclic. The polyamine base structures may also comprise polyamine branching chains to a greater or lesser degree. Preferably, the polyamine base structures described in the present invention are modified in such a way that at least one, preferably each nitrogen of the polyamine chain can be described, after said modification, in terms of a unit that is replaced, quaternized or oxidized or combinations thereof. For the purposes of the present invention, the term "modification" as it refers to the chemical structure of polyamines, is defined as replacing a hydrogen atom of the NH- group of the base structure with a unit R '(substitution), quatemize a nitrogen base structure (quaternized) or oxidize a nitrogen from the base structure to the N-oxide (oxidized). The terms "modification" and "substitution" are used interchangeably when referring to the process of replacing a hydrogen atom that is attached to a nitrogen of the base structure with a unit R '. Quaternization or oxidation may occur in certain circumstances without substitution, but substitution is accompanied by preference for the oxidation or quaternization of at least one nitrogen of the base structure. , .., ^ and ".". '^ ".. ..a ^ - ^ .. ^. &." vg-' .- < - ::.,.? _ii_ia_i «__ ll__te ' The non-cyclic or linear polyamine base structures comprising the amino functional polymer have the general formula: The cyclic polyamine base structures comprising the amino functional polymer have the general formula: R 'i R [R'2N-R] n.k + 1 [NR] m- [NR] n- [NR] k-NR'2 The above base structures, before the optional, but preferred subsequent modification, comprise primary, secondary and tertiary amine nitrogens connected by "linker" units R. For the purpose of the present invention, the nitrogens of Primary amine comprising the base structure or branching chain, once modified, are defined as "terminal" V or Z units. For example, when a primary amine portion, located at the end of the main polyamine base structure or branch chain having the structure H2H- [R] - is modified according to the present invention, is defined after modification as a "terminal" unit V, or simply a unit V. However, for the purposes of the present invention, some or all the primary amine portions can remain unmodified subject to the restrictions described in more detail later in the present invention. These unmodified primary amine portions, by virtue of their position in the base structure chain, remain as "terminal" units. Likewise, when a portion of primary amine, located at the end of the main polyamine base structure that has the structure -NH2 is modified according to the present invention, is defined, after modification, as a "terminal" unit Z, or simply a unit Z. This unit may remain unmodified subject to the restrictions described in more detail later in the present invention. Similarly, the secondary amine nitrogens comprising the base structure or branching chain, once modified, are defined as "base structure" units W. For example, when a secondary amine portion, the main constituent of the base structures and branching chains of the present invention, having the structure HI - [N-RJ - is modified according to the present invention, is defined , after the modification, as a unit W of "base structure", or simply a unit W. However, for the purposes of the present invention, some or all of the secondary amine portions may remain unmodified. These unmodified secondary amine portions, by virtue of their position in the base structure chain, remain as "base structure" units. In like manner, the tertiary amine nitrogens comprising the base structure or branching chain, once modified, are further defined as "branching" Y units. For example, when a tertiary amine moiety, which is a chain branching point either of the polyamine base structure or of other 10 branching chains or rings, having the structure I - [NR] - is modified in accordance with the present invention, is defined, after modification, as a "branching" unit Y, or simply a unit Y. However, for the purposes of the present invention, some or all of the tertiary amine portions may remain unmodified. These unmodified tertiary amine portions, by virtue of their position in the base structure chain, remain as "branching" units. Below, the R units associated with the nitrogens of unit V, W and Y which serve to connect polyamine nitrogens will be described. The modified final structure of the polyamines of the present invention can then be represented by the general formula: V (n + l) WmYnZ for the linear amino-functional polymer, and by the general formula , i.;., g, ._ tfa¿M¿ .-; ...., V (n-k + 1) WmYnY'kZ for the cyclic amino-functional polymer. For the case of the polyamines comprising rings, a unit Y 'of the formula: R - [N-RJ - serves as a branching point for a base structure or a branching ring. For each unit Y 'there exists a unit Y that has the formula: I - [N-R] - which will form the connection point of the ring to the chain or branch of the main polymer. In the single case in which the base structure is a complete ring, the base structure of polyamine has the formula: R 'II [R ^ N-RJn-IN-RJm-IN-Rln-therefore it does not comprise any terminal unit Z and has the formula Vn-k mYnY'k in which k is the number of ring-forming branch units. Preferably, the polyamine base structures of the present invention do not comprise rings. In the case of non-cyclic polyamines, the ratio of index n to index m refers to the relative degree of branching. A completely modified linear, unbranched polyamine according to the present invention has the formula: . - ^ £ hjBBifi t > IWto J_a_ t_Bl-tf VWmZ that is, n is equal to 0. The larger the value of n (the smaller the ratio of m to n), the greater the degree of branching in the molecule.
Typically, the value for m varies from a minimum value of 2 to 700, of preference of 4 to 400, however, values greater than m are also preferred, especially when the value of index n is very low or almost 0. Each polyamine nitrogen, whether primary, secondary or tertiary, once modified in accordance with the present invention, is further defined as a member of one of three general classes; simple replaced, quaternized or oxidized. Those unmodified polyamine nitrogen units are classified as units V, W, Y, Y 'or Z depending on whether they are primary, secondary or tertiary nitrogens. That is, the nitrogens of the unmodified primary amine are units V or Z, the nitrogens of the unmodified secondary amine are units W or units Y 'and the nitrogens of the unmodified tertiary amine are Y units for the purposes of the present invention. Modified primary amine moieties are defined as "terminal" units V having one of three forms: a) simple substituted units having the structure: R'-N- R - I R 'b) quaternized units that have the structure: ? t * in which X is an adequate counter-ion that provides load balance; and 5 c) oxidized units that have the structure: Modified secondary amine moieties are defined as 10"base structure" units W having one of three forms: a) simple substituted units having the structure: - N- R - I R 'b) Quaternized units that have the structure: in which X is an adequate counter-ion that provides a load balance; and c) oxidized units having the structure: / > i ^ ^ ^^ »^ 3 ^^^^. tm ^ & ^^ ^^ e ^ i ^ 7- ^ .., ^, ^? - ^« i. _ ^ ~ ^ _Íi__s iliri_ »? llH_a ^ -B? Other portions of modified secondary amine are defined as units Y 'having one of three forms: a) simple substituted units having the structure: - N- R - I R b) quaternized units that have the structure: in which X is an adequate counter-ion that provides load balance; and c) oxidized units having the structure: The modified tertiary amine moieties are defined as "branching" units and having one of three forms: a) unmodified units having the structure: - N-R - I J b) quaternized units that have the structure: R 'X "I. - N + - R- ,. .- - ^. I _ in which X is an adequate counter-ion that provides load balance; and c) oxidized units having the structure: Some portions of modified primary amine are defined as "terminal" Z units that have one of three forms: a) simple substituted units that have the structure: - N- R 'I R' b) quaternized units that have the structure: in which X is an adequate counter-ion that provides a load balance; and c) oxidized units having the structure: When any position on a nitrogen is not substituted or is not modified, it is understood that the hydrogen will replace R \ For example, a primary amine unit comprising a unit R 'in The form of a hydroxyethyl portion is a terminal unit V having the formula (HOCH2CH2) HN-. For the purposes of the present invention, there are two types of chain terminator units, the V and Z units. The unit "terminal" Z is obtained from a terminal primary amino portion of the -NH2 structure. The non-cyclic polyamine base structures according to the present invention comprise only one unit Z, while the cyclic polyamines may not comprise any unit Z. The "terminal" unit Z may be substituted with any of the R units described in greater detail later in the present invention, except when the unit Z is modified to form an N-oxide. In the case where the nitrogen of unit Z is oxidized to an N-oxide, the nitrogen must be modified and therefore R 'can not be a hydrogen. The polyamines of the present invention comprise units "linkers" R of base structure that serve to connect the nitrogen atoms of the base structure. The R units comprise units which for the purpose of the present invention are called "hydrocarbyl R" units and "oxy R" units. The "hydrocarbyl" R units are C 2 -C 2 alkylene, C -C 2 alkylene and C 3 -C 2 hydroxyalkylene in which the hydroxyl portion can occupy any position on the chain of unit R, except carbon atoms directly connected to the nitrogens of the polyamine base structure; dihydroxyalkylene of C -C 2 in which the hydroxyl portions can occupy any two of the carbon atoms of the sf chain of unit R, except those carbon atoms directly connected to the nitrogens of the base structure of polyamine; dialkylarylene of Cs-C? 2 which for the purpose of the present invention are arylene portions having two alkyl substituent groups as part of the linker chain. For example, a dialkylarylene unit has the formula: although it is not necessary that the unit be substituted in positions 1, 4-, but it can also be substituted in positions 1, 2- or 1, 3- with C 2 -C 2 alkylene, preferably ethylene, 1, 2-propylene and mixtures thereof, more preferred ethylene. The R "oxy" units comprise - (R1O)? R5 (OR1) x-, -CH2CH (OR2) CH20) z (R1O) and R1- (OCH2CH (OR2) CH2) w-, -CH2CH (OR2) CH2-, - (R10) xR1- and mixtures thereof. Preferred R units are selected from the group consisting of C 2 -C 2 alkylene, C 3 -C 2 hydroxyalkylene, C -C 2 dihydroxyalkylene, C 8 -C 12 dialkylarylene, - (R 1 O) x R 1 -, -CH2CH (OR2) CH2-, - (CH2CH (OH) CH20) z- (R10) and R1 (OCH2CH- (OH) CH2) w-, - (R10)?

The most preferred base structures of the present invention comprise at least 50% R units that are ethylene. The R1 units are C2-C6 alkylene and mixtures thereof, preferably ethylene. R2 is hydrogen and - (R1O) xB, preferably hydrogen. R3 is C-pC-is alkyl, C7-C2 arylalkylene, aryl substituted with C7-C2 alkyl, C6-C2 aryl, and mixtures thereof, preferably C6 alkyl. C12, C7-C-? 2 alkylarylene, more preferred alkyl of C? -C? 2, even more preferred methyl. The R3 units serve as part of the R units described later in the present invention. R4 is alkylene of C? -C-? 2, C4-C2 alkenylene, C8-C2 arylalkylene, C6-C6arylene, preferably Ci-C6 alkylene, C8-C2 arylalkylene, more preferred C2-C8 alkylene , even more preferably ethylene or butylene. R5 is C? -C-? 2 alkylene, C3-C? 2 hydroxyalkylene, C-C12-dihydroxyalkylene, C8-C-? 2-dialkylarylene, -C (O) -, -C (0) NHR6NHC ( 0) -, -C (0) (R6) rC (0) -, R1 (OR1) -, - (CH2CH (OH) CH20 (R10) and R1OCH2CH (OH) CH2-, -C (0) (R4) rC (0) -, - (CH2CH (OH) CH2-, R5 is preferably ethylene, -C (O) -, -C (O) NHR6NHC (0) -, -R1 (OR1) -, -CH2CH (OH) CH2-, - (CH2CH (OH) CH2O (R1O) and R1OCH2CH- (OH) CH2-, more preferred - (CH2CH (OH) CH2- .R6 is C2-C2 alkylene or C6-C2 arylene. "preferred" are also defined in terms of of the units R1, R2 and R5. The preferred R "oxy" units comprise the preferred R1, R2 and R5 units. Preferred cotton soil release agents of the present invention comprise at least 50% of R1 units that are ethylene. The preferred R1, R2 and R5 units are combined with the R "oxy" units to produce the preferred R "oxy" units in the following manner. i) substituting the most preferred R5 in - (CH2CH2O) xR5 (OCH2CH2) x- yields - (CH2CH2O) xCH2CHOHCH2- (OCH2CH2) -. ii) substituting the preferred R1 and R2 in - (CH2CH (OR2) CH20) z- (R10) and R10 (CH2CH (OR2) CH2) w- occurs - (CH2CH (OH) CH20) z- (CH2CH2O) and CH2CH2O (CH2CH (OH) CH2) w-. iii) substituting the preferred R2 in -CH2CH (OR2) CH2- produces -CH2CH (OH) CH2-. The R 'units are selected from the group consisting of hydrogen, C -? - C22 alkyl, C3-C22 alkenyl, C7-C22 arylalkyl, C2-C22 hydroxyalkyl, - (CH2) pC02M, - (CH2) qS03M , -CH (CH2C02M) CO2M, - (CH2) nP03M, - (R1O) mB, -C (0) R3, preferably hydrogen, C2-C22 hydroxyalkylene, benzyl, C-C22 alkylene, - (R10) mB, -C (0) R3, - (CH2) pCO2M, - (CH2) qS03M, -CH (CH2C02M) CO2M, more preferred C1-C22 alkylene, - (R1O) xB, -C (O) R3, - (CH2 ) pC02M, - (CH2) qS03M, -CH (CH2C02M) C02M, even more preferred is alkylene of CrC22, - (R10) xB and -C (0) R3. When no modification or substitution is made on a nitrogen, then the hydrogen atom will remain as the portion representing R '. An R 'unit that is most preferred is (R10) xB. The R 'units do not contain a hydrogen atom when the units V, W or Z are oxidized, that is, the nitrogens are N-oxides. For example, the chain or branching chains of the base structure do not comprise units of the following structure: Additionally, the R 'units do not comprise carbonyl moieties directly attached to a nitrogen atom when the units V, W and Z are oxidized, that is, the nitrogens are N-oxides. According to the present invention, the portion -C (O) R3 of the unit R 'is not bound to a modified nitrogen to N-oxide, that is, there are no N-oxide amides having the structure: or combinations thereof. B is hydrogen, C6 alkyl, - (CH2) qSO3M, - (CH2) pCO2M, - (CH2) q (CHSO3M) CH3SO3M, - (CH2) q (CHSO2M) CH2SO3M, - (CH2) pPO3M, -, -..- .. J j ^^ g_ ^^ _ ^^^^ A ^^^ ^^^^^^^^^^^^ -PO3M, preferably hydrogen, - (CH2) qS03M, - (CH2) q (CHS03M) CH2S03M, - (CH2) q (CHS02M) CH2S03M, more preferred hydrogen or - (CH2) qS03M. M is hydrogen or a cation soluble in water in an amount sufficient to satisfy the charge balance. For example, a sodium cation 5 similarly satisfies - (CH2) pCO M and - (CH2) qSO3M, resulting in the portions - (CH2) pC02Na and - (CH2) qS03Na. More than one monovalent cation (sodium, potassium, etc.) can be combined to satisfy the required chemical charge balance. However, the charge of more than one anionic group can be balanced by means of a divalent cation, or it can be It is necessary more than one monovalent cation to satisfy the loading requirements of a polyanionic radical. For example, a - (CH2) pPO3M portion substituted with sodium atoms has the formula - (CH2) pP03Na3. Divalent cations such as calcium (Ca2 +) or magnesium (Mg2 +), can be substituted by, or combined with, other water-soluble monovalent cations suitable. The preferred cations are sodium and potassium, the most preferred being sodium. X is a water-soluble anion such as chlorine (Cl "), bromine (Br) and iodine (I-) or X can be any negatively charged radicals such as sulfate (SO42") and methosulfate (CH3S03"). Formula indices have the following values: p has the value of 1 to 6, q has the value of 0 to 6, r has the value of 0 or 1, w has the value of 0 or 1, x has the value of 1 to 100, "y" has the value of 0 to 100, z has the value 0 or 1, m has the value of 2 to 700, preferably from 4 to 400, n has the value from 0 to 350, preferably from 0 to 200; the sum m + n has the value of at least 5. Preferably, x has a value that is in the range of 1 to 20, preferably 1 to 10. Preferred amino-functional polymers of the present invention comprise polyamine base structures in which less than 50% of the R groups comprise R "oxy" units, preferably less than 20%, more preferred less than 5%, even more preferred R units do not comprise R "oxy" units. The most preferred amino-functional polymers that do not comprise R "oxy" units comprise polyamine base structures in which less than 50% of the R groups comprise more than 3 carbon atoms. For example, ethylene, 1,2-propylene and 1,3-propylene comprise 3 or fewer carbon atoms and are the preferred "hydrocarbyl" R units. That is, when the R units of the base structure are C 2 -C 2 alkylene, it is preferred that they are C 2 -C 3 alkylene and more preferably ethylene. The amino-functional polymers of the present invention comprise homogenous and non-homogeneous modified polyamine base structures, in which 100% or less of the -NH units are modified. For the purpose of the present invention, the term "homogeneous polyamine base structure" is defined as a polyamine base structure having R units that are the same (ie, all are ethylene). However, this definition of equality does not exclude polyamines that comprise other foreign units that constitute the base structure of the polymer, which are present due to an artifact of the chosen chemical synthesis method. For example, those skilled in the art know that ethanolamine can be used as an "initiator" in the synthesis of polyethylenimines, therefore a polyethylenimine sample comprising a hydroxyethyl portion resulting from the polymerization "primer" will be considered to comprise a homogeneous polyamine base structure for the purposes of the present invention. A base structure of polyamine constituted by ethylene in all the units R in which branching units Y are not present is a homogeneous base structure. A base structure of polyamine constituted by ethylene in all R units is a homogeneous base structure regardless of the degree of branching or the number of cyclic branches present. For the purposes of the present invention, the term "non-homogeneous polymer base structure" refers to polyamine base structures which are a combination of various lengths of unit R and types of unit R. For example, an inhomogeneous base structure comprises R units that are a mixture of ethylene and 1, 2-propylene. For the purposes of the present invention, a mixture of "hydrocarbyl" and "oxy" units R is not necessary to provide a non-homogeneous base structure.
B? Ft_ftaiBg_t »É _iÍii The amino-functional polymers of the present invention comprise homogeneous polyamine base structures that are totally or partially substituted with polyethyleneoxy portions, with fully or partially quaternized amines, with fully or partially oxidized nitrogens up to N-oxides , and mixtures thereof. However, not all the nitrogens of the amine of the base structure must be modified in the same way, leaving the choice of modification to the specific needs of the formulator. The degree of ethoxylation is also determined by the specific requirements of the formulator. Preferred polyamines comprising the base structure of the compounds of the present invention are generally polyalkyleneimines (PAI's), preferably polyethyleneimines (PEI's), or PEI's connected by portions having longer R units than the PEI's PAI's of origin. The base structures of the preferred amine polymer comprise R units which are alkylene units of C2 (ethylene), also known as polyethylene imines (PEI's). Preferred PEIs have at least one moderate branching, ie, that the ratio of m to n is less than 4: 1, however, PEI's having a ratio of m to n of 2: 1 are more preferred. The base structures, before the modification, have the general formula: R 'l i I [2NCH2CH2] n - [NCH2CH2] m- [NCH2CH2] n- NR2 in which R \ m and n are the same as those defined above. The PEI's ^ > j ^ ^^% Ati _ ^ _ ya ^^^ g_alÍ ^ is¿ ^ w -. * fa »- preferred will have a molecular weight greater than 200 daltons. The relative proportions of the amine, primary, secondary and tertiary units in the polymer base structure, especially in the case of PEI's, will vary, depending on the form of preparation. Each hydrogen atom attached to each nitrogen atom of the polyamine base structure chain represents a potential site for subsequent substitution, quaternization or oxidation. These polyamines can be prepared, for example, by polymerizing ethyleneimine in the presence of a catalyst such as carbon dioxide, sodium bisulfite, sulfuric acid, hydrogen peroxide, hydrochloric acid, acetic acid, etc. The specific methods for preparing these polyamine base structures are described in the patent E.U.A. No. 2,182,306, Ulrich et al., Issued December 5, 1939; the patent E.U.A. No. 3,033,746, Mayle et al., Issued May 8, 1962; the patent E.U.A. No. 2,208,095, Esselman et al., Issued July 16, 1940; the patent E.U.A. No. 2,806,839, Crowther, issued September 17, 1957; and the patent E.U.A. No. 2,553,696, Wilson, issued May 21, 1951, all incorporated in the present invention for reference. Examples of amino-functional polymers comprising PEI's are illustrated in formulas I-IV: Formula I illustrates an amino-functional polymer comprising a base structure of PEI in which all substitutable nitrogens are modified by replacement of the hydrogen with a polyoxyalkylenoxy unit, - (CH 2 CH 20) 7 H, having the formula: This is an example of an amino-functional polymer that is completely modified by a type of portion. Formula II illustrates an amino-functional polymer comprising a PEI base structure in which all substitutable primary amine nitrogens are modified by replacement of the hydrogen with a polyoxyalkyleneoxy unit, - (CH2CH20) 7H, the molecule is then modified. by the subsequent oxidation of all primary and secondary nitrogens to N-oxides, said polymer has the formula: & _ »A_ _« __á_s_. The formula III illustrates an amino-functional polymer comprising a PEI base structure in which all the hydrogen atoms of the base structure are substituted and some amine units of the base structure are quaternized. The substituents are polyoxyalkylenoxy units, - (CH 2 CH 2 O) 7 H or methyl groups. The modified PEI polymer has the formula: Formula IV illustrates an amino-functional polymer comprising a base structure of PEI in which the nitrogens of the base structure are modified by substitution (ie with - (CH2CH20) 7H or methyl), quaternized, oxidized to N-oxides or combinations thereof. The resulting polymer has the formula: In the previous examples, not all the nitrogens of a unit class comprise the same modification. The present invention allows the formulator to have ethoxylated a portion of the nitrogens of the secondary amine while having the other nitrogens of the secondary amine oxidized to N-oxides. This also applies to the primary amine nitrogens, in the sense that the formulator can choose to modify all or a portion of the primary amine nitrogens with one or more substituents before oxidation or quaternization. Any possible combination of R 'groups can be substituted on the nitrogens of the primary or secondary amine, except for the restrictions described above in the present invention. Commercially available amino-functional polymers suitable for use in the present invention are poly (ethyleneimine) with PM 1200, hydroxyethylated poly (ethyleneimine) from Polysciences, with a MW of 2,000 and 80% hydroxyethylated poly (ethylenimine) of Aldrich. _i »< sa and 'A typical amount of the amino-functional polymer to be used in the composition of the invention when used as the sole nitrogenous compound is greater than 1%, preferably up to 50% by weight, more preferred greater than 1% up to 25% by weight, and more preferred even greater than 1% up to 10% by weight of the composition.
Dye Fixative Agent Dye fixative agents, or "fixatives," are well known, and are commercially available materials that are designed to improve the appearance of dyed fabrics by minimizing the loss of dye from fabrics due to washing. Within this definition are not included the components that are fabric softeners or those described later in the present invention as amino-functional polymers. Many dye-fixing agents are cationic, and are based on various organic nitrogen compounds quaternized or otherwise cationically charged. Cationic fixatives are available under various trade names from different suppliers. Representative examples include CROSCOLOR PMF (July 1981, code No. 7894) and CROSCOLOR NOFF (January 1988, code No. 8544) from Crosfield; INDOSOL E-50 (February 27, 1984, reference no 6008.35.84, based on polyethyleneamine) from Sandoz; SANDOFIX TPS, which is also available from Sandoz and is a preferred polycationic fixative for use in the present invention and SANDOFIX SWE (cationic resinous compound), REWIN SRF, REWIN SRF-0 and REWIN DWR from CHT-Beitlich GMBH, Tinofix® ECO , Tinofix® FRD and Solfin® available from Ciba-Geigy. Other cationic dye fixing agents are described in "Aftertreatments for improving the fastness of dyes on textile fibers" by Christopher C. Cook (REV PROG. COLORATION Vol. 12, 1982). Dye fixing agents suitable for use in the present invention are ammonium compounds such as fatty acid diamine condensates such as hydrochloride, acetate, methosulfate and benzyl hydrochloride of oleyldiethyl aminoethylamide, oleylmethyldietilenediamine methosulfate, monostearylethylenediaminetrimethylammonium methosulfate and products. oxidized tertiary amines; derivatives of polymeric alkyldiamines, polyamine-cyanuric chloride condensates and aminated glycerol dichlorohydrins. Preferred dye fixing agents are dye fixing agents that react with cellulose. By the phrase "dye fixing agent which reacts with cellulose" is meant that the agent reacts with the cellulose fibers under heat treatment. Suitable agents for use in the present invention can be defined by the following test procedure, called cellulose reactivity test measurement.
Measurement of reactivity test with cellulose Two pieces of fading cloth (for example 10 x 10 cm of cotton fabric dyed with Direct Red 80) are soaked for 20 minutes in an aqueous solution of 1% (w / w) of the agent candidate dye fixative reactive with cellulose. The pH of the solution is the one obtained at this concentration. The samples are dried afterwards. One of the dry samples, as well as a non-soaked sample (control 1) are passed 10 times through an ironing roll adjusted for linen. A control sample 2 is also used in this measurement test which is a sample not soaked and not ironed. The four samples are washed separately in Launder-o-meter containers under typical conditions with a commercial detergent used at the recommended dose for half an hour at 60 ° C, followed by a careful rinse four times with 200 ml of cold water and then They tend to dry. The firmness to washing in the samples is then measured by determining their so-called delta-E values against a new and untreated sample. The delta E values are defined, for example, in ASTM D2244. Delta E is the difference in color calculated as defined in ASTM D2244, that is, the magnitude and direction of the difference between two psycho-physical color stimuli defined by tristimulus values, or by chromaticity and luminance factor coordinates, as calculated by means of a specific set of color difference equations defined in CIEL 1976 CIELAB opponent-color space, Hunter's opponent-color space, Friele-Mac Adam-Chickering color space or any equivalent color space. Therefore, the lower the Delta E versus the new, the better the wash firmness will be. If the improvement in the washing firmness of the soaked and ironed sample is better than that of the soaked non-ironed sample and also better than that of the respective controls 1 and 2, then the candidate is a cellulose-reactive dye fixing agent for the purpose of the invention. Cellulose-reactive dye fixing agents are products containing the reactive group of the reactive dye classes selected from halogen-triazine products, vinylsulfone compounds, epichlorohydrin derivatives, hydroxyethylene urea derivatives, formaldehyde condensation products, polycarboxylates, derivatives of glyoxal and glutaraldehyde and mixtures thereof.

Hemingway; U.S. Patent No. 4,439,335, Burns, issued March 27, 1984; and U.S. Patent No. 3,861, 870, Edwards and Diehl; 4,308,151, Cambre; 3,886,075, Bemardino; 4,233,164, Davis; 4,401, 578, Verbruggen; 3,974,076, Wiersema and Rieke; 4,237,016, Rudkin, Clint and Young; and the publication of European patent application No. 472,178, by Yamamura, et. to the.; all those documents incorporated herein by reference. Of course, the term "softening active" may also encompass mixed softening active agents. Among the classes of softening compounds that are preferred described above in the present invention are the fabric softening active compound of diester or quaternary ammonium diamide (DEQA). Fully formulated softening compositions preferably contain, in addition to the compounds described above in the present invention, one or more of the following ingredients. _É_S_ &, __ < ___- * OPTIONAL INGREDIENTS (A) Liquid Vehicle Another optional, but preferred, ingredient is a liquid vehicle. The liquid vehicle used in the present compositions is preferably at least mostly water due to its low cost, relative availability, safety and compatibility with the environment. The water level in the liquid vehicle is preferably at least 50%, more preferred at least 60%, by weight of the vehicle. Mixtures of water and low molecular weight organic solvent, for example < Approximately 200, for example lower alcohols such as ethanol, propanol, isopropanol or butanol are useful as the liquid carrier. Low molecular weight alcohols include monohydric, dihydric (glycol, etc.), trihydric (glycerol, etc.) alcohols and polyhydric higher alcohols (polyols).
(B) Additional solvents The compositions of the present invention may comprise one or more solvents that provide increased formulation ease. These easy-to-formulate solvents are all described in WO 97/03169. This is particularly the case when formulating liquid compositions and clear fabric softeners. When employed, the formulation ease solvent system preferably comprises less than about 40%, preferably about 10% to about 35%, most preferably about 12% to about 25%, and even more preferably about 14% to about 20%, by weight of the composition. The formulation ease solvent is selected to minimize the impact of solvent odor in the composition, and to provide a low viscosity to the final composition. For example, isopropyl alcohol is not very effective and has a strong odor. N-propyl alcohol is more effective, but it also has a distinctive odor. Several butyl alcohols also have odors but can be used for effective clarity / stability, especially when used as part of a solvent system of ease of formulation to reduce its odor as much as possible. The alcohols are also selected for optimum stability at low temperatures, i.e. they are capable of forming compositions that are liquid with low acceptable viscosities and translucent, preferably clear, up to 4.4 ° C, and are capable of recovering after of its storage up to -6.7 ° C. The suitability of any major solvent for the formulation of the liquid, concentrated, preferably clear fabric softening compositions of the present with the necessary stability is surprisingly selective. The suitable solvents can be selected based on its octanol / water separation coefficient (P) as defined in WO 97/03169. The easy-to-formulate solvents of the present are selected from those having a ClogP of about 0.15 to kt »Je ^ S ^ ß ^^^ l &. ^ ¡? s * gí ^ a¿íÁ & ^^, - ^^ Í ^ A.}. ~ r ^. »" ,. , - -. «& & amp; , about 0.64, preferably about 0.25 to about 0.62, and most preferably about 0.40 to about 0.60, said ease of formulation solvent being preferably at least somewhat asymmetric, and preferably having a melting or solidification point that gives it Allow to be liquid at or near room temperature. Solvents that have a low molecular weight and are biodegradable are also desirable for some purposes. The most asymmetric solvents appear to be very desirable, while highly symmetrical solvents, such as 1,7-heptanediol or 1,4-bis (hydroxymethyl) cyclohexane, which have a center of symmetry, appear to be incapable of providing clear essential compositions when used alone, even though their ClogP values are on the preferred scale. The most preferred easy-to-formulate solvents can be is identified by the appearance of the softener vesicles, as observed by cryogenic electron microscopy of the compositions that have been diluted to the concentration used in the rinse. These diluted compositions appear to have fabric softener dispersions that exhibit a more unilamellar appearance than the compositions conventional fabric softeners. The more unilaminar the appearance, the better the compositions seem to act. These compositions provide surprisingly adequate fabric softening compared to similar compositions prepared in the conventional manner with the same ia »« B_J_, _ aigafeA ».- active fabric softener. The easy-to-operate solvents are described and listed below, which have ClogP values that are within the necessary scale. These include mono-oles, diols of C6, and diols of C7, isomers of octanediol, derivatives of butanediol, isomers of trimethylpentanediol, isomers of ethylmethylpentanediol, isomers of propylpentanediol, isomers of dimethylhexanediol, isomers of ethylhexanediol, isomers of methylheptanediol, isomers of octanediol , isanomers of nonanodiol, alkylglyceryl ethers, di (hydroxyalkyl) ethers and arylglyceryl ethers, aromatic glyceryl ethers, acrylic diols and derivatives, alkoxylated derivatives of C3C7 diol, aromatic diols and unsaturated diols. Particularly preferred formulation ease solvents include hexanediols such as 1,2-hexanediol; and C8 diols such as 2-ethyl-1,3-hexanediol and 2,2,4-trimethyl-1,3-pentanediol.
(C) Dispersibility Aids Relatively concentrated compositions can be prepared containing quaternary ammonium diester compounds both saturated and unsaturated which are stable without the addition of concentration aids. However, the compositions of the present invention may require organic and / or inorganic concentration aids to obtain still higher concentrations and / or to satisfy higher stability standards, depending on the other ingredients. These concentration aids which typically can be viscosity modifiers may be required, or preferred, to ensure stability under extreme conditions when particular levels of softening active are used. The surfactant concentration aids are typically selected from the group consisting of (1) individual long chain alkyl cationic surfactants; (2) nonionic surfactants; (3) amine oxides; (4) fatty acids and (5) mixtures thereof. These auxiliaries are described in WO 94/20597, specifically on page 14, line 12 to page 20, line 12, which is incorporated in the present invention for reference. When said dispersion capacity auxiliaries are present, the total level is from 2% to 25%, preferably from 3% to 17%, preferably from 4% to 15% and even more preferred from 5% to 13% by weight of the composition. These materials may be added as part of the raw material of the active softener, (I), for example, the fatty acid which are reactants used to form the biodegradable fabric softening active as described above, or are added as a separate component. . The total dispersion capacity auxiliary level includes any quantity that may be present as part of the component (I). Inorganic viscosity control / dispersing ability agents that can also act as or increase the effect of surfactant concentration aids, include ionizable salts Water soluble which may also optionally be incorporated into the compositions of the present invention. A wide variety of ionizable salts can be used. Examples of suitable salts are the halides of group IA and NA of metals of the Periodic Table of the Elements, for example, calcium chloride, magnesium chloride, sodium chloride, potassium bromide and lithium chloride. Ionizable salts are particularly useful during the process of mixing the ingredients to make the compositions herein, and then to obtain the desired viscosity. The amount of ionizable salts used depends on the amount of active ingredients used in the compositions and can be adjusted according to the wishes of the formulator. Typical levels of the salts used to control the viscosity of the composition are from about 20 to about 20,000 parts per million (ppm), preferably from about 20 to about 11,000 ppm, by weight of the composition. Alkylene polyammonium salts may be incorporated into the composition to give viscosity control in addition to, or in place of, the above water-soluble ionizable salts. In addition, these agents can act as scavengers, forming ion pairs with the anionic detergent of the main wash, in the rinse and on the fabrics, and can improve the yield of softness. These agents can stabilize the viscosity on a broader temperature scale, especially at low temperatures, compared to inorganic electrolytes. Specific examples of alkylenepolyammonium salts include l-lysine monohydrochloride ; ^ ¿¿í y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y (D) Stabilizers Stabilizers may be present in the compositions of the present invention. The term "stabilizer", as used in the present invention, includes antioxidants and reducing agents. These agents are present at a level of from 0% to 2%, preferably from 0.01% to 0.2%, more preferred from 0.035% to 0.1% for antioxidants, and most preferably from 0.01% to 0.2% for reducing agents. These ensure an odor stability Suitable under long-term storage conditions for the compositions and compounds stored in molten form. The stabilizers of antioxidant and reducing agent are especially critical for products without aroma or low aroma (with little perfume). Examples of antioxidants that can be added to the compositions of this invention include a mixture of ascorbic acid, ascorbic palmitate and propylgalate, available from Eastman Chemical Products, Inc., under the trade names Tenox® PG and Tenox® S-1; a mixture of BHT (butylated hydroxytoluene), BHA (butylated hydroxyanisole), propylgalate and citric acid, available from Eastman Chemical Products, Inc., under the trade name Tenox-6; butylated hydroxytoluene, available from UOP Process Division under the trade name Sustane® BTH; tertiary butylhydroquinone, Eastman Chemical Products, Inc., as Tenox® TBHQ; natural tocopherols, Eastman Chemical Products, Inc., as Tenox® GT-1 / GT-2; and butylated hydroxyanisole, Eastman Chemical Products, Inc., as BHA; long chain esters (C8-C22) of gallic acid, for example, dodecylgalate; Irganox® 1010; Irganox® 1035; Irganox® B 1171; Irganox® 1425; Irganox® 3114; Irganox® 3125 and mixtures thereof; preferably Irganox® 3125; Irganox® 1425, Irganox® 3114 and mixtures thereof; most preferred Irganox® 3125 alone or mixed with citric acid and / or other chelating agents such as propyl citrate, Dequest® 2010, available from Monsanto with a chemical name of 1-hydroxyethylidene-1,1-diphosphonic acid (etridronic acid) and Tiro®, available from Kodak with a chemical name of 4,5-dihydroxy-m-benzenesulfonic acid / sodium salt, EDDS, and DTPA®, available from Aldrich with a chemical name of diethylenetriaminepentaacetic acid.

(E) Soil release agent For convenience, soil release agents are used in fabric softening compositions of the present invention. Any polymeric soil release agent known to the person skilled in the art can be optionally employed in the compositions of this invention. Polymeric soil release agents are characterized by having both hydrophilic segments, to render the surface of hydrophobic fibers such as polyester and nylon hydrophilic, and hydrophobic segments to be deposited on the hydrophobic fibers and remain adhered to them until the washing and rinsing cycles are completed, thus serving as an anchor for the hydrophilic segments. This can make stains that appear after treatment with the soil release agent easier to clean in subsequent cleaning procedures. If used, the soil release agents will generally comprise from about 0.01% to about 10.0% by weight of the detergent compositions of the present invention, typically from about 0.1% to 5%, preferably from about 0.2% to about 3.0%.

Organomonophosphonic acid refers in the present invention to an organomonophosphonic acid that does not contain nitrogen as part of its chemical structure As a consequence, this definition excludes organo-aminophosphonates, which, however, can be included in compositions of the invention as heavy metal ion sequestrants. The organomonophosphonic acid component can be present in its acid form or in the form of one of its salts or complexes with a suitable counter cation. Preferably, any of the salts / complexes is soluble in water, the salts / complexes of alkali metal and alkaline earth metal being especially preferred. A preferred organomonophosphonic acid is 2-phosphonobutane-1, 2,4-tricarboxylic acid commercially available from Bayer under the trade name of Bayhibit.

A 750 g portion of polyethylenimine (PEI) (Nippon Shokubai, Epomin SP-018 having a listed average molecular weight of 1800, equivalent to 0.417 moles of polymer and 17.4 moles of nitrogen) is added to the autoclave. The autoclave is then sealed and purged of air (applying vacuum to minus 711 mm Hg followed by pressurization with nitrogen at 17.57 kg / cm ^, then ventilating at atmospheric pressure). The contents of the autoclave are heated to 130 ° C while vacuum is applied. After about one hour, the autoclave is charged with nitrogen at about 17.57 kg / cm ^ while the autoclave is cooled to about 105 ° C. Ethylene oxide is then added to the autoclave in increments over time while carefully monitoring the pressure, temperature and flow rate of ethylene oxide in the autoclave. The ethylene oxide pump is turned off and cooling is applied to limit any increase in temperature that results from any reaction exotherms. The temperature is maintained between 100 and 110 ° C while the total pressure is allowed to gradually increase during the course of the reaction. After a total of 750 grams of ethylene oxide have been charged into the autoclave (almost equivalent to one mole of ethylene oxide per function of PEI nitrogen), the temperature is increased to 110 ° C and the autoclave is allowed to stir for one more hour.

The methoxide solution is sucked into the autoclave under vacuum and then the programming point of the autoclave temperature controller is increased to 130 ° C. A device is used to monitor the energy consumed by the agitator. The power of the agitator is monitored together with the temperature and pressure. The power and temperature values of the agitator increase gradually as the methanol is removed from the autoclave, and the viscosity of the mixture increases and stabilizes at about 1 hour indicating that most of the methanol has been removed. The mixture is ^ ^^^^ - ^^^, ^? ^^ iá heated and further stirred under vacuum for 30 minutes more. The vacuum is removed and the autoclave is cooled to 105 ° C while it is charged with nitrogen at 17.57 kg / cm2 and then ventilated at ambient pressure.

After achieving the addition of 4,500 g of ethylene oxide (resulting in a total of 7 moles of ethylene oxide per mole of nitrogen function of PEI) for several hours, the temperature is increased to 110 ° C and the mixture is Shake for one more hour. The reaction mixture is then collected in nitrogen purged containers and is eventually transferred to a 22-liter, three-necked ball flask equipped with heating and stirring.
