Description

COMPOSITIONS FOR THE CARE OF FABRICS TECHNICAL FIELD A composition is provided that provides care to the treated fabrics, in particular protection to the colors, especially after multiple washing cycles.

BACKGROUND OF THE INVENTION Domestic treatment of dyed fabrics is a problem known in the art for the formulator of laundry compositions. Accordingly, it is well known that alternative cycles of use and washing of fabrics and textiles, such as articles of clothing and clothing, will inevitably adversely affect the appearance and integrity of the fabric and textile articles thus used and washed. Fabrics and textiles simply wear out over time and with use. The washing of fabrics and textiles is necessary to remove the dirt and stains that accumulate on them and on them during ordinary use. However, the washing operation itself, during many cycles, can accentuate and contribute to the deterioration of the integrity and appearance of said fabrics and textiles.

The deterioration of the integrity and appearance of the fabric can manifest itself in several ways. The short fibers are detached from the textile structures / woven fabric by the mechanical action of washing. These detached fibers can form lint, lint or "pills" that are visible on the surface of the fabrics and diminish the new appearance of the fabric. In addition, repeated washing of fabrics and textiles, especially with laundry products containing bleach, can remove the colorant from fabrics and textiles, and impart a worn and discolored appearance as a result of the decreased intensity of the colors and, in many cases, as a result of changes in shades or tones of color. Accordingly, the problem of formulating laundry compositions that reduce the amount of dyes released from the colored fabrics after wet treatment is a particular challenge for the formulator. This problem is now even more acute with consumer trends for preferring more colored fabrics. Many solutions in the art have been proposed to solve this problem, such as treating the fabric with a dye sweeper during the washing process, as exemplified in EP 0,341, 205, EP 0,033,815, or with a polyvinyl substance, as exemplified in WO 94/11482. However, all these solutions are focused on preventing the final result of the coloration of the dye, that is, the redeposition of the dye on the fabrics. It is now a object of the invention to face the problem of coloring in one of its origins, that is, the discoloration that arises from the bleed of the dye due to its poor substantivity in the fabric, especially after multiple washes. Solutions applicable to industrial treatments can be found. However, these solutions can not usually be extrapolated to household treatments. Of course, in industrial processes, it is possible to have strict control over parameters such as pH, electrolyte concentration, water hardness, temperature, etc., while in a domestic washing machine, such a high level of control is not possible. Furthermore, in a domestic process, and in particular in a domestic rinsing process, it is not practical to rely on high treatment temperatures such as those used in industrial processes, which are greater than 40 ° C. In addition, industrial processes use high concentrations of fixing agents that are required for treatment on an industrial scale, while for domestic treatment, a low level is preferred for economic reasons. Accordingly, regardless of advances in the art, there is still a need for an efficient and economical composition that allows for the effective reduction of the amount of dyes released from the dyed fabrics after subsequent domestic wet treatments.

EP462806 provides the use of a cationic dye fixing agent in the home treatment, which helps to bind the dye little fixed to the fabric. However, although efficient, it has been found that discoloration of the fabrics occurred to a certain degree, especially after multiple washing cycles. Accordingly, it is therefore an advantage of the invention to provide compositions with effective dye fixing properties. Another advantage of the invention is that said compositions provide a synergistic increase in the benefit yield mentioned above. Another advantage of the invention is that the treated fabrics will then show a reduced tendency in the subsequent washing, to the release of the colorant. Said benefit is more particularly observed after multiple washing cycles (for example, 20 washing cycles).

BRIEF DESCRIPTION OF THE INVENTION The present invention relates to a composition for the care of colors, comprising a dye fixing agent and a divalent salt. In another aspect of the invention, the use and method thereof is provided to prevent or reduce discoloration of the fabrics by the divalent salt.

Dye fixing agent The dye fixing agent is an essential component of the composition of the invention. The dye fixing agents, or "fixatives", are well known and commercially available materials, which are designed to improve the appearance of the dyed fabrics, minimizing the loss of dye from the fabrics due to washing. Not included within this definition are the components that are fabric softeners, or those described below as aminofunctional polymers. Many dye fixing agents are cationic, and are based on various quaternized or otherwise cationically charged organic nitrogen compounds. Cationic fixatives are available under various trade names from various 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, Ref. 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 herein, and SANDOFIX SWE (cationic resinous compound), REWIN SRF, REWIN SRF-O 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, for example, hydrochloride, acetate, methosulfate and benzyl hydrochloride of oleyldiethyl aminoethylamide, diethylene diamine methyl sulfate, monostearyl ethylenediaminetrimethylamino methosulfate, and oxidized products of tertiary amines; derivatives of polymeric alkyldiamines, polyamine-cyanuric chloride condensates, and aminated glycerol dichlorohydrins. Preferred dye fixing agents are cellulose reactive dye fixing agents. By "cellulose reactive dye fixing agent", it is meant that the agent reacts with the cellulose fibers after heat treatment. Suitable agents for use herein can be defined by the following test procedure, called cellulose reactivity test measurement.

Measurement of cellulose reactivity test Two pieces of fabric with colorant bleed (for example, x 10 cm of cotton fabric dyed with direct red 80), are immersed for 20 minutes in an aqueous solution of 1% (w / w) of the candidate cellulose reactive dye binding agent. The pH of the solution is how it is obtained at this concentration. The samples are then dried. One of the dried samples, as well as a sample without soaking (control 1) are made pass 10 times through an ironing ironing equipment on a linen background. A control sample 2 is also used in this measurement test, which is a sample without soaking and without ironing. The 4 samples are washed separately in Launder-o-meter containers under typical conditions with a commercial detergent used at the recommended dosage for half an hour at 60 ° C, followed by a full rinse of 4 times in 200 ml of cold water, and dried then on linen. The wash fastness is then measured in the samples by determining the so-called delta E values against a new untreated sample. The delta E values are defined, for example, in ASTM D2244. Delta E is the calculated color difference as defined in ASTM D2244, that is, the magnitude and direction of the difference between two psychophysical stimuli by color defined by values of 3 stimuli, or by chromaticity and luminance factor coordinates, calculated by means of a specific series of color difference equations defined in the CIELAB CIÉ 1976 opponent color space, the Hunter color opponent space, the Friele-Mac Adam-Chickering color space, or any equivalent color space. Therefore, the smaller the delta value E against the new delta E value, the better the improvement of the wash firmness.

If the improvement of the firmness to washing of the ironed-soaked sample is better than that of the sample soaked without ironing, and also better than that of the two respective controls 1 and 2, then the candidate is a reactive dye fixing agent to cellulose useful for the purpose of the invention. Typical cellulose-reactive dye fixing agents are the products containing the reactive group of reactive dye classes selected from halogen-triazine products, vinylsulfone compounds, epichlorohydrin derivatives, hydroxyethylene urea derivatives, formaldehyde condensation products, polycarboxylates , glyoxal and glutaraldehyde derivatives, and mixtures thereof. Other reactive functionalities for cellulose can be found in Textile processing and properties, Elsevier (1997) by Tyrone L. Vigo on pages 120 to 121, where the use of specific electrophilic groups with affinity for cellulose is provided. Preferred hydroxyethyleneurea derivatives include dimethyloldihydroxyethylene, urea and dimethyl urea glyoxal. Preferred formaldehyde condensation products include the condensation products derived from formaldehyde and a group selected from an amino group, an imino group, a phenol group, a urea group, a cyanamide group and an aromatic group. Commercially available compounds of this class are Sandofix WE 56 from Clariant, Zetex E from Zeneca and Levogen BF from Bayer.

Preferred polycarboxylate derivatives include butane tetracarboxylic acid derivatives, citric acid derivatives, polyacrylates, and derivatives thereof. More preferred reactive cellulosic dye fixing agents are those of the class of hydroxyethyleneurea derivatives marketed under the trade name Indosol CR from Clariant. Other more preferred cellulosic reactive fixing agents are marketed under the tradename of Rewin DWR and Rewin WBS of CHT R. Beitlich. Among the dye fixing agents described, the preferred agent for use in the present invention are cationic, in particular, polycationic dye fixing agents. A typical amount of the dye fixing agent to be used in the composition of the invention is from 0.01% to 50% by weight, preferably from 0.01% to 25% by weight, more preferably from 1% to 10% by weight, very preferably from 1.5% to 5% by weight of the composition.

Divalent salt A divalent salt is an essential ingredient of the invention. By using this ingredient, the appearance of the fabric is improved, in particular the protection of the colors of the fabrics. Without being limited by theory, it is thought that the salt acts by reducing the solubility of the dyes.

A divalent salt is defined as a salt that dissociates in water and releases a metal ion with a valence of two. The salt useful in the present invention is formed of alkaline earth metal, and is a compound that can form hydrates after crystallization. Typically, the salt for use in the present invention has the following formula: AM, wherein A is a cation. This cation is an alkaline earth metal, preferably selected from magnesium, calcium, more preferably magnesium, and wherein M is a counterion selected from sulfate, chloride, nitrate, carbonate, borate and carboxylates. Preferred salts are selected salts of magnesium, calcium, and mixtures thereof; more preferably magnesium salt. Particularly preferred salts for use herein are selected from magnesium sulfate, magnesium bicarbonate, magnesium chloride, magnesium borate, magnesium citrate, and mixtures thereof, more preferably selected from magnesium sulfate, magnesium chloride, magnesium, and mixtures thereof. A typical amount of the divalent salt to be used in the composition of the present invention is from 0.01% to 90% by weight, preferably 0.5% and 90%, more preferably between 1% and 20%, most preferably between 3% and 10%, by weight of the composition. For the purposes of the invention, it is preferred that it have a weight ratio of the divalent salt: dye fixing agent, greater than 1: 1.

Component for the care of the colors The compositions for the care of the fabrics can also comprise one or more of the following components for the care of the colors: Aminofunctional polymer Aminofunctional polymers advantageously provide care for the colors of fabrics. Not included within this definition are the components that are polymers as defined hereinbefore, or those described below as dye fixing agents. Aminofunctional polymers suitable for use in the present invention are water soluble or dispersible polyamines. Typically, the aminofunctional polymers for use herein have a molecular weight between 150 and 106, preferably between 600 and 20,000, more preferably 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 herein are modified such that at least one nitrogen of the polyamine chain (preferably all) are described below in terms of a unit that is substituted, quaternized, oxidized, or combinations thereof.

For the purposes of the present invention, the term "modification" as it refers to the chemical structure of the polyamine, is defined as the replacement of a hydrogen atom of -NH from the base structure with an R 'unit (substitution) , quaternization of a nitrogen of the base structure (quaternization) or oxidation of a nitrogen from the base structure to N-oxide (oxidation). The terms "modification" and "Substitution" are used interchangeably when referring to the process of replacing a hydrogen atom attached to a nitrogen of the base structure, with a unit R '. The quaternization or oxidation may take place in some circumstances without substitution, but preferably the substitution is accompanied by oxidation or quaternization of at least one nitrogen of the base structure. The linear or non-cyclic polyamine base structures comprising the aminofunctional polymer have the general formula: The cyclic polyamine base structures comprising the aminofunctional polymer have the general formula: | R 'i R [N-R] m- [N-R] - [N-R] k-NR'2 The above base structures, before the subsequent optional but preferred modification, comprise primary, secondary and tertiary amine nitrogens linked by "linker" units R. For the purposes of the present invention, the primary amine nitrogens comprising the base structure or branch chain once modified, are defined as units " terminals "V or Z. For example, when a primary amine portion, located at the end of the main base structure of the polyamine or branching chain, having the structure H2N- [R] -is modified in accordance with the present invention, is hereinafter defined as a "terminal" V unit, or simply unit V. However, for the purposes of the present invention, some or all of the primary amine portions may remain unmodified, subject to the restrictions that are they describe in the present later. These unmodified primary amine portions, by virtue of their position in the chain of the base structure, remain as "terminal" units. Likewise, when a portion of primary amine, located at the end of the main base structure of polyamine, having the structure -NH2 is modified in accordance with the present invention, hereinafter it is defined as a "terminal" unit Z, or simply a unit Z. This unit It may remain unchanged, subject to the restrictions described herein below. 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, which have the structure: H - [NR] - is modified in accordance with the present invention, is then defined 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 portions of secondary amine may remain unmodified. These unmodified secondary amine portions, by virtue of their position in the chain of the base structure, remain as units of the "base structure". In a similar manner, the tertiary amine nitrogens comprising the base structure or branching chain, once modified, are further referred to as "branching" Y units. For example when, a portion of tertiary amine, which is a chain branching point of the base structure of polyamine or other chains of branching or rings, which have the structure: - [N-R] - be modified in accordance with the present invention, then it is defined as a "branching" Y unit or simply a Y unit.

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 chain of the base structure, remain as "branching" units. The R units associated with the nitrogens of the units V, W and Y, which serve to bind the polyamine nitrogens, are described in FIG. present later. The final modified structure of the polyamines of the present invention can therefore be represented by means of the general formula V (n + 1) WmYn Z for the linear amino-functional polymer, and for the general formula V (n-k + 1) WmYr V for the cyclic amino-functional polymer. For the case of polyamines comprising rings, a unit Y 'of the formula: R - [N-R] - serves as a branch point for a base structure or a ring of branching. For each unit Y ', there exists a unit Y that has the formula: - [N-R] - which forms the point of attachment of the ring with the polymer backbone or branching. In the only case in which the base structure is a complete ring, the polyamine base structure has the formula: R 'i [R'2N-R] n - [N-R] m- [N-R] n therefore, it does not comprise terminal Z unit and has the formula: Vn-kWmYnY'k where k is the number of branching units forming the ring. Preferably, the polyamine base structures of the present invention do not comprise rings. In the case of non-cyclic polyamines, the ratio of the index n to the index m, refers to the relative degree of branching. A linear modified polyamine completely unbranched in accordance with the present invention has the formula: VWm Z that is, n is equal to 0. The higher the value of n (the lower the proportion of man), the greater the degree of branching in the molecule. Typically, the value of m varies from a minimum value of 2 to 700, preferably 4 to 400; without However, larger values of m are also preferred, especially when the value of the index n is very low or close to 0. Each polyamine nitrogen, whether primary, secondary or tertiary, once modified in accordance with the present invention, is later defined as a member of one of three general classes; replaced, quaternized or oxidized. Unmodified polyamine nitrogen units are classified into units V, W, Y, Y 'or Z, depending on whether they are primary nitrogens, secondary or tertiary. That is, the unmodified primary amine nitrogens are V or Z units, the unmodified secondary amine nitrogens are units W or Y ', and the unmodified tertiary amine nitrogens are Y units, for the purposes of the present invention. Modified portions of primary amine are defined as "terminal" units V, and have one of three forms: a) simple substituted units that have the structure: R'-N- R- I R ' b) quaternized units that have the structure: where X is an adequate counter ion that provides balance of load; and c) oxidized units having the structure: Modified secondary amine portions are defined as "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: where X is an adequate counter ion that provides balance of load; and c) oxidized units having the structure: Other portions of modified secondary amine are defined as units Y 'having one of three forms: a) simple substituted units that have the structure: - N-R- I R b) quaternized units that have the structure: R 'X "I - N + - R - I R where 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 Y "branching" units having one of three forms: a) unmodified units having the structure: - N- R- b) quaternized units that have the structure: where X is an adequate counter ion that provides balance of load; and c) oxidized units having the structure: Certain portions of modified primary amine are defined as Z "terminal" 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: where X is an adequate counter-ion that provides 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 R 'will be substituted by hydrogen. By example, a primary amine unit comprising an R 'unit in the form of a hydroxyethyl portion, is a V-terminal unit 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 Z unit "terminal" is derived from a terminal primary amine portion of the structure - NH2. The non-cyclic polyamine base structures according to the present invention comprise only one unit Z, while the cyclic polyamines may not comprise units Z. The "terminal" Z unit may be substituted with any of the R 'units described above forward in the present, except when 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 serving to join 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" units R are C2-C12 alkylene. C4-C12 alkenylene and C3-C12 hydroxyalkylene. wherein the hydroxyl portion can take any position on the chain of unit R, except the carbon atoms directly attached to the nitrogens of the polyamine base structure; C4- dihydroxyalkylene C-J2 wherein the hydroxyl portions may occupy any two of the carbon atoms of the chain of the R unit, except those carbon atoms directly attached to the nitrogens of the polyamine base structure; C8-C12 dialkylarylene 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 the unit does not need to be 1, 4-substituted, but it can also be 1, 2- or 1, 3-substituted with C2-C12 alkylene. preferably ethylene, 1,2-propylene, and mixtures thereof, most preferably ethylene. The "oxy" R units comprise - (R10) xR5 (OR) x-, CH2CH (OR2) CH20) z (R10) and R1 - (OCH2CH (OR2) CH2) w-. CH2CH (OR2) CH2-, - (R10) XR1 -, and mixtures thereof. Preferred R units are C2-C12 alkylene.

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) by substituting the preferred R5 in (CH2CH2?) xR5 (OCH2CH2) x-, (CH2CH2?) xCH2CHOHCH2- (OCH2CH2) x- is produced. I) substituting the preferred R1 and R2 in (CH2CH (OR2) CH2?) Z- (R10) and R10 (CH2CH (OR2) CH2) w-, produces - (CH2CH (OH) CH20) z- (CH2CH2?) and CH2CH2?

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 '. A highly preferred unit R 'is (R10) xB. The units R 'do not comprise hydrogen atoms when the units V, W or Z are oxidized, that is, the nitrogens are N-oxides. For example, the base structure chain or branching chains 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 or Z are oxidized, that is, the nitrogens are N-oxides. From In accordance with the present invention, the portion -C (0) R3 of the unit R 'is not bound to a modified nitrogen in N-oxide, that is, there is no N-oxide of amides having the structure: or combinations thereof. B is hydrogen, Ci-Cß alkyl, - (CH 2) qS 3 3M, - (CH 2) pC02M, (CH 2) q- (CHS03M) CH 2 S0 3M, (CH 2) q (CHS0 2M) CH 2 S 3M, - (CH 2) pP03M , - PO3M, preferably hydrogen, - (CH2) qS? 3M, (CH2) q (CHS03M) CH2S? 3M, (CH2) q- (CHS02M) CH2S? 3M, most preferably 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 also satisfies - (CH2) pC? 2M and - (CH2) qS? 3M, resulting in portions (CH2) pC? 2Na and - (CH2) qS? 3Na. 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 more than one monovalent cation may be necessary to satisfy the loading requirements of a polyanionic radical. For example, a portion - (CH2) pP? 3M substituted with Sodium atoms have the formula - (CH2) pP03Na3. The divalent cations such as calcium (Ca2 +) or magnesium (Mg2 +) can be substituted by, or combined with, other suitable water-soluble monovalent cations. The preferred cations are sodium and potassium, and sodium is very preferred. 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 (CH3SO3-). The indexes of the formulas 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; and has the value from 0 to 100; z has the value 0 or 1; m has the value from 2 to 700, preferably from 4 to 400, n has the value from 0 to 350, preferably from 0 to 200; m + n has the value of at least 5. Preferably x has a value that is on the scale of 1 to 20, preferably 1 to 10. Preferred aminofunctional polymers of the present invention comprise polyamine base structures in which less than about 50% of the R groups comprise "oxy" R units, preferably less than about 20%, preferably less than 5%, most preferably the R units do not comprise "oxy" R units. The highly preferred aminofunctional polymers which do not comprise R "oxy" units, comprise polyamine base structures in which less than 50% of the R groups comprise more than 3 atoms of carbon. For example, ethylene, 1,2-propionate 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 C2-C12 alkylene, C2-C3 alkylene is preferred and more ethylene is preferred. The aminofunctional polymers of the present invention comprise homogenous and nonhomogeneous 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 the same R units (ie, all are ethylene). However, this definition of equality does not exclude polyamines comprising other foreign units comprising the polymer base structure, 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 polyethylene imines, therefore a polyethylene imine sample comprising a hydroxyethyl portion originating from the polymerization "primer" would be considered, comprises a homogeneous polyamine base structure for the purposes of the present invention. A polyamine base structure comprising all ethylene R units in which no branching Y units are present, is a homogeneous base structure. A polyamine base structure comprising all R units of ethylene is a homogeneous base structure regardless of the degree of branching or the number of cyclic branches present. For purposes of the present invention, the term "non-homogeneous polymer base structure" refers to polyamine base structures that are a mixture of various lengths of unit R and types of unit R. For example, a base structure non-homogeneous comprises R units which are a mixture of ethylene and 1,2-propylene units. For purposes of the present invention, a mixture of "hydrocarbyl" and "oxy" R units is not necessary to provide a non-homogeneous base structure. Preferred aminofunctional polymers of the present invention comprise homogeneous base structures of polyamine which are totally or partially substituted with polyethyleneoxy moieties, total or partially quaternized amines, nitrogens totally or partially oxidized to N-oxides, and mixtures thereof. However, not all the nitrogens of the amine 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), polyethylenimines (PEI's), or PEI's joined in portions having longer R units than the PAI's, or original PEI's. The preferred amine polymer base structures they comprise units R which are alkylene units of C2 (ethylene), also known as polyethyleneimines (PEI's). Preferred PEIs have at least 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 preferred base structures, before modification, have the general formula: R 'I [R, 2NCH2CH2] n - [NCH2CH2] m- [NCH2CH2] n- NR'2 where R ', m and n are the same as defined above. Preferred PEI's will have a molecular weight of more than 200 daltons. The relative proportions of the primary, secondary and tertiary amine units in the polyamine 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 U.S. patent. No. 2,182,306, Ulrich et al., Issued December 5, 1939; the patent of E.U.A. Do not. 3,033,746, Mayle et al., Issued May 8, 1962; the patent of E.U.A.

No. 2,553,696, Wilson, issued May 21, 1951; all incorporated herein by reference. 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.

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.

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%.

In the above fabric softener example, the -02CR1 unit represents a fatty acyl unit that is typically derived from a triglyceride source. The source of triglycerides is derived preferably of tallow, partially hydrogenated tallow, lard, partially hydrogenated butter, vegetable oils and / or vegetable oils partially hydrogenated, such as canola oil, safflower oil, peanut oil, sunflower oil, corn oil, soybean oil, wood oil, rice bran oil, and mixtures thereof. The fabric softening active compounds which are preferred in the present invention are the diester and / or quaternary ammonium diamide compounds (DEQA), the diesters and diamides having the formula: wherein R, R1, X and n are the same as those defined hereinabove for formulas (1) and (2), and Q has the formula: These preferred fabric softening active compounds are formed from the reaction of an amine with a fatty acyl unit to form an amine intermediate having the formula: wherein R is preferably methyl, Q and R1 are as defined above in the present invention; followed by quaternization to the final softening active compound.

Non-limiting examples of the preferred amines that are used to form the fabric softening active compounds of DEQA according to the present invention include methyl-bs (2-hydroxyethyl) amine having the formula: methyl-bis (2-hydroxypropyl) amine having the formula: methyl- (3-aminopropyl) (2-hydroxyethyl) amine having the formula: methyl-bis (2-aminoethyl) amine having the formula: triethanolamine that has the formula: HO ' H di (2-aminoethyl) ethanolamine having the formula: The counterion, X (_> above, can be any anion compatible with the softener, preferably the anion of a strong acid, for example, chloride, bromide, methyl sulfate, ethyl sulfate, sulfate, nitrate and the like, more preferred chloride or methyl sulfate The anion can also, but is less preferred, carry a double charge in which case X (_) represents half of a group.The sebum and canola oil are convenient and inexpensive sources of fatty acid acyl units that are Suitable for use in the present invention as R1 units The following examples are non-limiting examples of quaternary ammonium compounds suitable for use in the compositions of the present invention The term "seboyl" as used later in the present invention indicates that the unit R1 is obtained from a source of tallow triglycerides and is a mixture of alkyl or alkenyl units of fatty acid, likewise, the use of the term canolyl refers to a mixture of alkyl or alkenyl units of fatty acid obtained from canola oil. The following list describes non-limiting examples of the fabric softener suitable according to the above formula. In this list, the term "oxy" defines a unit OR II - C - while the term "oxo" defines a unit -O- TABLE II Fabric softening active compounds N, N-di (tallowyloxy-2-oxo-ethyl) -N-methyl, N- (2-hydroxyethyl) chloride ammonium; N, N-di (canolyl-oxy-2-oxo-ethyl) -N-methyl, N- (2-hydroxyethyl) chloride ammonium; N, N-di (tallowoyloxy-2-oxo-ethyl) -N, N-dimethylammonium chloride; N, N-di (canyloxy-2-oxo-ethyl) -N, N-dimethylammonium chloride; N, N, N-tri (tallowyloxy-2-oxo-ethyl) -N-methylammonium chloride; N, N, N-tri (canolol-oxy-2-oxo-ethyl) -N-methylammonium chloride; N- (tallowoyloxy-2-oxo-ethyl) -N- (tallowyl) -N, N-dimethylammonium chloride; N- (caninoxy-2-oxo-ethyl) -N- (canolyl) -N, N-dimethylammonium chloride; 1, 2-di (tallowoxy-oxo) -3-N, N, N-trimethylammonopropane chloride; 1, 2-di (canolabyloxy-oxo) -3-N, N, N -trimethylammoniopropane chloride; and mixtures of the above active compound ingredients. Other examples of quaternary ammonium softening compounds are methylbis (tallowamidoethyl) (2-hydroxyethyl) ammonium methylisulfate and methylbis metisulfate (hydrogenated tallow amidoethyl) (2-hydroxyethyl) ammonium; these materials are available from Witco Chemical Company under the tradenames Varisoft® 222 and Varisoft® 110, respectively. N, N-di (tallowyloxy-2-oxo-ethyl) -N-methyl, N- (2-hydroxyethyl) ammonium chloride, in which the tallow chains are at least partially unsaturated, is particularly preferred. The level of unsaturation contained within tallow, canola or other acyl fatty acid chain can be measured by the corresponding iodine (IV) value of the fatty acid, which in the present case should preferably be in the range of 5 to 100, distinguishing two categories of compounds that have an IV of less than or more than 25. In fact, for compounds that have the formula: tallow fatty acid derivatives, when the Iodine Value is from 5 to 25, preferably 15 to 20, it has been found that a weight ratio of the cis / trans isomer of more than about 30/70, preferably more than about 50 / 50 and most preferably more than about 70/30, provides optimum concentration ability. For compounds of this type made from tallow fatty acids having an Iodine Value of more than 25, the ratio of the isomers cis to trans has been found to be less critical, unless very high concentrations are required. Other suitable examples of fabric softening active compounds are derived from fatty acyl groups in which the terms "seboyl" and "canolyl" in the above examples are replaced by the terms "cocoyl, palmyl, lauryl, oleyl, ricinoleyl, stearyl, palmityl" ", which correspond to the source of triglycerides from which the fatty acyl units are derived. These alternative fatty acyl sources can comprise unsaturated chains either completely saturated, or preferably at least partially saturated. As described hereinabove, the R units are preferably methyl, however, fabric softening active compounds suitable are described by replacing the term "methyl" in the above examples of Table I with the units "ethyl, ethoxy, propyl, propoxy, isopropyl, butyl, isobutyl and t-butyl. " The counter ion X in the examples of Table II can be suitably replaced by bromide, methylisulfate, formate, sulfate, nitrate, and mixtures thereof. In fact, the X anion is present simply as a counter ion of the positively charged quaternary amino compounds. The scope of this invention is not considered to be limited to any particular anion. For the above ester fabric softening agents, the pH of the compositions herein is an important parameter of the present invention. In fact, it influences the stability of the quaternary ammonium compounds or amine precursors, especially under conditions of prolonged storage. The pH, as defined in the present context, is measured in the concentrated compositions at 20 ° C. Although these compositions can operate at a pH of less than about 6.0, for optimum hydrolytic stability of these compositions, the concentrated pH, measured under the conditions mentioned above, should preferably be in the range of about 2.0 to 5, preferably in the scale from 2.5 to 4.5, preferably around 2.5 to about 3.5. The pH of the compositions herein can be regulated by the addition of a Bronsted acid. Examples of suitable acids include inorganic mineral acids, carboxylic acids, in particular low molecular weight (C 1 -C 5) carboxylic acids and alkylsulfonic acids. Suitable inorganic acids include HCl, H2SO4, HN03 and H3P04. Suitable organic acids include formic, acetic, citric, methylsulfonic and ethylsulfonic acids. The acids that are preferred are citric, hydrochloric, phosphoric, formic, methylsulphonic and benzoic acids. As used in the present invention, when the diester is specified, it will include the monoester which is normally present during manufacture. For smoothing, under laundry conditions without drag / low detergent drag, the percentage of monoester should be as low as possible, preferably not greater than about 2.5%. However, under conditions of high detergent drag, a certain amount of monoester is preferred. The general ratios of diester to monoester are from about 100: 1 to about 2: 1, preferably from about 50: 1 to about 5: 1, more preferred from about 13: 1 to about 8: 1. Under conditions of high detergent carryover, the di / monoester ratio is preferably about 11: 1. The level of monoester present can be controlled during the manufacture of the softening compound. Mixtures of the active compounds of formulas (1) and (2) can also be prepared. 2) Other quaternary ammonium fabric softening compounds suitable for use herein are the cationic nitrogen salts having two or more long chain aliphatic and acyclic Cs-C22 hydrocarbon groups., or one of those groups and an arylalkyl group which may be used alone or as part of a mixture are selected from the group consisting of: (i) non-cyclic quaternary ammonium salts having the formula: wherein R 4 is an acyclic and aliphatic C 8 -C 22 hydrocarbon group, R 5 is a saturated C 1 -C 4 alkyl or hydroxyalkyl group, R 8 is selected from the group consisting of groups R 4 and R 5, and A- is an anion as defined previously; (I) Diamino alkoxylated quaternary ammonium salts having the formula: wherein n is equal to 1 to 5, and R1, R2, R5 and A "are as defined above, (iii) mixtures thereof Examples of the cationic nitrogen salts of the above class are the well known salts of dialkyldimethylammonium such as ditallowdimethylammonium chloride, ditallowdimethylammonium methylisulfate, di (hydrogenated tallow) dimethylammonium chloride, distearyldimethylammonium chloride, dibehenyldimethylammonium chloride Di (hydrogenated tallow) dimethylammonium chloride and ditallowdimethylammonium chloride are preferred Examples of commercially available ditalkyldimethylammonium salts useful in the present invention are di (hydrogenated tallow) dimethylammonium chloride (trade name Adogen® 442), ditallow dimethyl ammonium chloride (trade name) Adogen®470, Praepagen® 3445), distearyldimethylammonium chloride (trade name Arosurf® TA-100), all available from Witco Chemical Company.

The fabric softening agents additional useful in the present invention are described in the patent of E.U.A. No. 4,661, 269, issued April 8, 1987 in the names of Toan Trinh, Errol H. Wahl, Donald M. Swartley, and Ronald L. Hemingway; E.U.A. Patent No. 4,439,335, of Burns, issued March 27, 1984 and in the patents of E.U.A. Nos. 3,861, 870, Edwards and Diehl; 4,308,151, Cambre; 3,886,075, Bernardino; 4,233,164, Davis; 4,401, 578, Verbruggen; 3,974,076, Wiersema and Rieke; 4,237,016, Rudkin, Clint, and Young; and in the publication of European patent application No. 472,128, Yamamura et al., All the mentioned documents being 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 diester and / or diamide quaternary ammonium fabric softening active compound (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.

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 are useful, for example < 200, for example lower alcohols such as ethanol, propanol, isopropanol or butanol. Low molecular weight alcohols they 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 an increased ease for the formulation. These solvents to facilitate the formulation are all described in WO 97/03169. This is particularly the case when liquid, clear fabric softening compositions are formulated. When employed, the solvent system for facilitating the formulation preferably comprises less than about 40%, preferably from about 10% to about 35%, most preferably from about 12% to about 25%, and very much preferably still about 14% about 20% by weight of the composition. The solvent for facilitating the formulation is selected to minimize the impact of solvent odor on 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. Various butyl alcohols also have odors but can be used for effective clarity / stability, especially when used as part of a solvent system to facilitate formulation and minimize odors. Alcohols are also selected for optimum low temperature stability, that is, they can form compositions that are liquid with viscosities acceptably low and translucent, preferably clear, below about 4.4 ° C and can recover after storage below about minus 6.7 ° C. The suitability of any solvent to facilitate the formulation for the formulation of liquid fabric softener compositions, preferably clear in the present with the required stability is surprisingly selective. Suitable solvents can be selected based on their octanol / water partition coefficient (P) as defined in WO 97/03169. The solvents for facilitating the formulation of the present invention are selected from those having a ClogP of from about 0.15 to about 0.64, preferably from 0.25 to about 0.62 and much very preferably from about 0.40 to about 0.60, said solvent to facilitate the formulation preferably being at least a little asymmetric, and preferably having a melting point, or solidification, which allows it 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 more asymmetric the solvents appear to be more desirable, while the solvents that are very symmetrical like 1,7-heptadienol, or 1,4-bis (hydroxymethyl) cyclohexane, which have a center of symmetry, apparently can not provide essentially clear compositions when used alone, even when their ClogP values fall on a preferred scale.

Solvents to facilitate formulation more preferably can be identified by the appearance of softening vesicles, as observed by cryogenic electron microscopy of the compositions that have been diluted to the concentration used in the rinse. These diluted compositions apparently have fabric softener dispersions that exhibit a more unilamellar appearance than conventional fabric softener compositions. The closer the appearance to unilaminar, the better the compositions seem to perform. These compositions surprisingly provide good fabric softening when compared to similar compositions prepared in the conventional manner with the same fabric softening active. The solvents to facilitate the formulation that work in the present are described and listed below, which have ClogP values that fall within the requirement margin. These include mono-oles, diols of C6, diols of C7, isomers of octanediol, derivatives of butanediol, isomers trimethylpentanediol, isomers of ethylmethylpentanediol, isomers of propylpentanediol, isomers of dimethylhexanediol, isomers of ethylhexanediol, isomers of methylheptanediol, isomers of octanediol, isomers of nonanodiol, alkylglyceryl ethers, di (hydroxyalkyl) ethers, and arylglyceryl ethers, glyceryl aromatic ethers, alicyclic diols and derivatives, alkoxylated C3-C diols, aromatic diols and unsaturated diols. Preferred formulation facilitating solvents include hexanediols such as 1,2-hexanediol and 2-ethyl-1,3-hexanediol and pentanediols such as 2,2,4-trimethyl-1,3-pentanediol.

B) Scattering Aids Relatively concentrated compositions can be prepared which contain 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 from page 14, line 12 to page 20, line 12, of the document written in the original language, 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%, of preference from 4% to 15% and more preferred still from 5% to 13% by weight of the composition. These materials can be added as part of the starting material of the active softener, (I), for example, the long-chain mono-alkyl cationic surfactant and / or the fatty acid, which are reactants used to form the active softener of biodegradable fabrics as described above here, 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 / dispersion-controlling agents that can also act or increase the effect of the auxiliaries on the concentration of the surfactant include water-soluble ionizable salts which can 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 the metals of group IA and HA 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 subsequently obtaining the desired viscosity. The amount of ionizable salts used depends on the amount of active ingredients that are used in the compositions and can be adjusted according to what the formulator desires. Typical levels of used salts to control the viscosity of the composition are about 20 about 20,000 parts per million (ppm), preferably from about 20 to about 11,000 ppm, by weight of the composition. The alkylene polyammonium salts can be incorporated into the composition to control the viscosity in addition to or instead of the aforementioned water-soluble ionizable salts. In addition, these agents can act as scavengers, forming ion pairs with the anionic detergent transported from the main wash, in the rinse and in the fabric, and can improve the performance of the softness. These agents can stabilize the viscosity over a wide range of temperatures, especially at low temperatures, compared to inorganic electrolytes. Examples, specific for alkylenepolyammonium salts include 1-lysine monohydrochloride and 1,5-diammonium 2-methylpentane dihydrochloride.

A cylinder of -9.06 kg net of ethylene oxide (ARC) is installed to supply ethylene oxide as a liquid by means of a pump to the autoclave with the cylinder placed on a scale to be able to monitor the changes in weight of the cylinder. 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 functions) 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 / cm2 absolute, 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 approximately 17.57 kg / cm2 absolute while the autoclave is cooled to approximately 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 exotherm. The temperature is maintained between 100 and 110 ° C while allowing the total pressure to increase gradually during the course of the reaction. After a total of 750 grams of ethylene oxide in the autoclave (almost equivalent to one mole of ethylene oxide per nitrogen function of PEI), the temperature is increased to 110 ° C and the autoclave is allowed to stir for another hour. At this point, vacuum is applied to remove any unreacted residual ethylene oxide. Step B) The reaction mixture is then deodorized by passing about 2.831 cm3 of inert gas (argon or nitrogen) through a gas dispersion frit and through the reaction mixture while stirring and heating the mixture to 130 ° C. The final reaction product is cooled slightly and collected in glass containers purged with nitrogen. In other preparations, neutralization and deodorization are achieved in the reactor before discharging the product. If a PEI 1800 E7 is desired, the next catalyst addition step between steps A and B will be included. Vacuum is applied continuously while the autoclave is cooled to approximately 50 ° C by introducing 376 g of a sodium methoxide solution at 25 ° C. % in a methanol solution (1.74 moles, to achieve a catalyst load of 10% based on the nitrogen functions of PEI). 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 heated and further stirred under vacuum for a further 30 minutes. The vacuum is removed and the autoclave is cooled to 105 ° C while it is charged with nitrogen at 17.57 kg / cm2 absolute and then ventilated at ambient pressure. The autoclave is charged at 14.06 kg / cm2 absolute with nitrogen. Ethylene oxide is again added to the autoclave in increments as mentioned above, carefully monitoring the pressure, temperature and flow velocity of ethylene oxide in the autoclave, while maintaining the temperature between 100 and 110 ° C and limiting any increase in the temperature due to the exotherm of the reaction. 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 stirred for an additional 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. The strong alkaline catalyst is neutralized by adding 167 g of methanesulfonic acid (1.74 moles).

Other preferred examples such as PEI 1800 E3, PEI 1800 E4, PEI 1800 E15 and PEI 1800 E20 can be prepared by the above method by adjusting the reaction time and the relative amount of ethylene oxide used in the reaction.

A cylinder of ~ 9.06 kg net of ethylene oxide (ARC) is installed to supply ethylene oxide as a liquid by means of a pump to the autoclave placing the cylinder on a scale to be able to monitor the changes in weight of the cylinder. A 750 g portion of polyethylenimine (PEI) (having a listed average molecular weight of 1200, equivalents to 0.625 moles of polymer and 17.4 moles of nitrogen functions) is added to the autoclave. The autoclave is then sealed and purged of air (applying a vacuum to minus 711 mm Hg followed by application of nitrogen pressure at 17.57 kg / cm2 absolute then ventilating at atmospheric pressure). The contents of the autoclave are heated to 130 ° C while vacuum is applied. After approximately one hour, the autoclave is charged with nitrogen at approximately 17.57 kg / cm2 absolute while the autoclave is cooled to approximately 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 cog is applied to limit any increase in temperature that results from any reaction exotherm. 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 an additional hour. At this point, vacuum is applied to remove any residual ethylene oxide that did not react. Step B) The reaction mixture is then deodorized by passing about 2.831 cm3 of inert gas (argon or nitrogen) through a gas dispersion frit and through the reaction mixture while stirring and heating the mixture to 130 ° C. The final reaction product is cooled slightly and collected in glass containers purged with nitrogen. In other preparations, neutralization and deodorization are achieved in the reactor before discharging the product.

If a PEI 1200 E7 is desired, the next catalyst addition step between steps A and B will be included. Vacuum is applied continuously while the autoclave is cooled to approximately 50 ° C by introducing 376 g of a 25% sodium methoxide solution. % in methanol (1.74 moles, to achieve a catalyst load of 10% based on the nitrogen functions of PEI). 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 in about one hour indicating that most of the methanol has been removed. The mixture is heated and further stirred under vacuum for an additional 30 minutes. The vacuum is removed and the autoclave is cooled to 105 ° C while it is charged with nitrogen at 17.57 kg / cm2 absolute and then vented at ambient pressure. The autoclave is charged at 14.06 kg / cm2 absolute with nitrogen. Ethylene oxide is again added to the autoclave in increments as mentioned above, carefully monitoring the pressure, temperature and flow rate of ethylene oxide in the autoclave, while maintaining the temperature between 100 and 110 ° C and limiting any increase in temperature due to the exotherm of the reaction.

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 Shake for an additional hour. The reaction mixture is then collected in nitrogen purged containers and optionally transferred to a 22-liter, three-necked ball flask equipped with heating and stirring. The strong alkaline catalyst is neutralized by adding 167 g of methanesulfonic acid (1.74 moles). Other preferred examples can be prepared such as PEI 1200 E2, PEI 1200 E4, PEI 1200 E15 and PEI 1200 E20 by the above method adjusting the reaction time and the relative amount of ethylene oxide used in the reaction.
