Description

[Technical field]

[0001] The present disclosure relates to treatment compositions comprising a surfactant system and an oligoamine. The present disclosure further relates to methods of using and preparing such compositions. [Background technology]

[0002] Many treatment processes, such as laundry cleaning processes, are designed to remove stains from surfaces, such as fabrics. Some stains can cause malodors on fabrics, which may persist or even form after the treatment process. Thus, manufacturers of consumer and industrial cleaning products seek to provide compositions and processes that provide improved malodor control.

[0003] Separately, certain polyamines or oligoamines are known for use in detergent compositions. Such polyamines or oligoamines can promote certain cleaning benefits, such as grease removal. However, such compounds may cause discoloration, such as yellowing of fabrics. Summary of the Invention [Problem to be solved by the invention]

[0004] There is a need to provide compositions which provide improved malodor control, especially where such compositions allow for more efficient use of oligoamines. [Means for solving the problem]

[0005] The present disclosure relates to treatment compositions having specific oligoamines and / or salts thereof and specific surfactant systems.

[0006] For example, the present disclosure provides a treatment composition comprising an oligoamine and / or a salt thereof and a surfactant system, wherein the oligoamine is present at a concentration of about 0.01% to 3.0% by weight of the treatment composition, and the oligoamine has the formula I:

[0007] [ka] [wherein each L is independently -(C m H 2m )-, the subscript m is, independently for each L, an integer from 2 to 6; n is an integer from 1 to 10; R 1 ~R 5 is independently selected from H and C1-C4 alkyl, typically R 1 ~R 5 wherein at least one of is H, and the surfactant system includes a linear alkyl benzene sulfonate (LAS) surfactant.

[0008] The present disclosure also relates to a process for treating a surface, comprising the steps of: (a) providing a surface, preferably a fabric, more preferably a fabric soiled with sebum; and (b) contacting the surface with a composition described herein, optionally in the presence of water.

[0009] The present disclosure also relates to the use of a surfactant system in a fabric care composition to improve the malodor control benefit of an oligoamine and / or its salt on a target fabric, the surfactant system comprising a linear alkylbenzene sulfonate surfactant and the oligoamine having a structure according to formula I described herein. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The present disclosure relates to a treatment composition comprising an oligoamine and a linear alkylbenzene sulfonate (LAS) surfactant.It has been found that such oligoamines can provide surprising odor benefits, for example on laundered fabrics, and that these benefits can be improved in compositions that include LAS.

[0011] Without being bound by theory, it is believed that the copper ions (e.g., Cu 2+It is believed that metal ions such as copper ions, ...

[0012] Furthermore, it has been found that the combination of the oligoamines of the present invention with the LAS surfactant can provide a surprisingly good malodor control effect. Without being bound by theory, it is believed that the attachment of the oligoamines onto the target surface can be assisted by the LAS surfactant, for example, via hydrophobic interactions. The more efficient the attachment of the oligoamines, the more they may inhibit the decomposition of the soil that causes the malodor. The mechanism by which such an effect is provided is not intuitive, since the oligoamines and anionic surfactants, such as LAS, typically provide the effect by removing the soil from the surface. The LAS may be part of a surfactant system that may include one or more additional surfactants.

[0028] The oligoamines and surfactant systems of the present disclosure are described in more detail below.

[0029] Oligoamines The treatment composition of the present disclosure includes an oligoamine or a salt thereof. The oligoamine according to the present disclosure may be a primary, secondary, or tertiary amine that contains an amine functional group and is linked via a specific alkylene group. Without being bound by theory, the oligoamine of the present disclosure is believed to be capable of reacting with copper (Cu 2+ ), and it is believed that such chelation can provide a malodor control benefit.

[0030] The treatment composition of the present disclosure may comprise from about 0.01% or about 0.05% by weight of the treatment composition to about 3.0%, about 2.0%, about 1.0%, about 0.75%, about 0.5%, about 0.4%, about 0.3%, about 0.2%, about 0.15%, or about 0.1% by weight of the oligoamine. For the purposes of this disclosure, the weight percentage of the linear oligoamine is calculated using the weight of the free base form. Depending on the intended use and / or formulation, a relatively low concentration of the oligoamine (e.g., less than about 1%, or less than about 0.5%, or less than about 0.2%, or less than about 0.1%) may be preferred, since the amine may cause discoloration / yellowing of certain surfaces.

[0031] The oligoamines of the present disclosure can be considered to be linear oligoamines. By "linear" we mean that there are no additional amine-containing side chains grafted onto the oligoamine backbone represented by formula I. However, it is understood that linear oligoamines may, at least in some cases, have alkyl groups attached to the oligoamine backbone, such as methyl or ethyl groups.

[0032] The oligoamines of the present disclosure have formula I:

[0033] [ka] [In the formula, Each L is independently -(C m H 2m )-, the subscript m is, independently for each L, an integer from 2 to 6, preferably m is 2 or 3, more preferably m is 2 (e.g., an ethylene group); n is an integer from 1 to 10 (i.e., triamine, tetramine, pentamine, hexamine, heptamine, etc.), preferably an integer from 1 to 5, more preferably an integer from 1 to 3, even more preferably an integer from 1 to 2, and most preferably an integer of 1; R 1 ~R 5 each of R is independently selected from H and C1-C4 alkyl, preferably H and methyl (i.e., C1 alkyl). When n is greater than 1, each R 5 are independently selected from the group shown, where each R 5 It is understood that may be the same.

[0034] The subscript m, independently for each L, may be an integer from 2 to 6, and the subscript m is 2 or 3, preferably 2, for each of two L groups that are directly linked to a common N atom. Having two such L groups adjacent to a common N atom is believed to promote improved metal sequestration, even when the other L group is relatively large (e.g., when m is greater than 2).

[0035] R 1 ~R 5 Each of R may be H. 5 R may be methyl. 5 may be H. 1 and R 3 One or both of R may be methyl. 1 and R 3 may be methyl, R 2 and R 4 R may both be hydrogen. 1 ~R 5 Each of R may be methyl. 1 ~R 5At least one of R is H, and even more preferably 1 ~R 4 It may be preferred that at least one of R is H. 1 ~R 4 may be H, R 5 may be independently selected from H and C alkyl.

[0036] The composition comprises a compound represented by formula I, wherein L, m, n, and R 1 ~R 5 is defined above, with the proviso that when n is equal to 1, R5 is selected from H and a moiety having 1-10 carbons, or 1-6 carbons, or 1-4 carbons.

[0037] Depending on the type of product desired and / or overall performance margin, formulators may select oligoamines with primary, secondary, and / or tertiary nitrogens, especially in terminal positions. Without being bound by theory, it is believed that the presence of primary nitrogen in the oligoamines of the present invention can provide improved malodor control efficacy, which is believed to be due to improved chelating efficiency and / or coordination to target surfaces such as fabrics. Also, without being bound by theory, it is believed that the tertiary nitrogen in the oligoamines of the present invention can be less reactive with other materials in the treatment composition, such as with certain perfume materials that may otherwise react (e.g., Schiff base reaction) and result in color changes in liquid products.

[0038] Treatment compositions containing mixtures of various oligoamines according to Formula I are also part of the scope of this disclosure.

[0039] Suitable oligoamines according to the present disclosure can include diethylenetriamine (DETA), 4-methyldiethylenetriamine (4-MeDETA), dipropylenetriamine (DPTA), 5-methyldipropylenetriamine (5-MeDPTA), triethylenetetraamine (TETA), 4-methyltriethylenetetraamine (4-MeTETA), 4,7-dimethyltriethylenetetraamine (4,7-Me2TETA), 1,1,4,7,7-pentamethyldiethylenetriamine (M5-DETA), tripropylenetetraamine (TPTA), tetraethylenepentamine (TEPA), tetrapropylenepentamine (TPPA), pentaethylenehexamine (PEHA), pentapropylenehexamine (PPHA), hexaethyleneheptamine (HEHA), hexapropyleneheptamine (HPHA), N,N'-bis(3-aminopropyl)ethylenediamine, or mixtures thereof.

[0040] The oligoamine is preferably diethylenetriamine (DETA), 4-methyldiethylenetriamine (4-MeDETA), 1,1,4,7,7-pentamethyldiethylenetriamine (M5-DETA), dipropylenetriamine (DPTA), 5-methyldipropylenetriamine (5-MeDPTA), triethylenetetramine (TETA), tripropylenetetraamine (TPTA), tetraethylenepentamine (TEPA), tetrapropylenepentamine (TPTA), N,N'-bis(3-aminopropyl)ethylenediamine, and mixtures thereof, more preferably diethylenetriamine. The diethylenetriamine may be selected from diethylenetriamine (DETA), 4-methyldiethylenetriamine (4-MeDETA), 1,1,4,7,7-pentamethyldiethylenetriamine (M5-DETA), triethylenetetramine (TETA), tetraethylenepentamine (TEPA), N,N'-bis(3-aminopropyl)ethylenediamine, and mixtures thereof, even more preferably diethylenetriamine (DETA), 4-methyldiethylenetriamine (4-MeDETA), N,N'-bis(3-aminopropyl)ethylenediamine, and mixtures thereof, and most preferably diethylenetriamine (DETA). DETA may be preferred due to its low molecular weight and / or relatively low manufacturing costs.

[0041] The oligoamine is diethylenetriamine ("DETA"), where m is equal to 2, n is equal to 1, and R 1 ~R 5 each of R 1 ~R 5 wherein one or more of the DETA groups are alkyl groups such as methyl. The oligoamines may comprise at least 80% by weight of the oligoamine in the form of diethylenetriamine (DETA), or even at least 90% by weight, or even at least 95% by weight, and even more preferably the oligoamines consist of the form of diethylenetriamine (DETA). The oligoamines may be selected from DETA, 4-methylDETA, and mixtures thereof, preferably DETA (non-alkylated diethylenetriamine).

[0042] Depending on the pH of the final product or cleaning solution, the nitrogen atom may be partially or fully protonated, resulting in the salt form of the oligoamine according to formula I. These (partially) protonated oligoamines may also be considered as part of the scope of the present disclosure. When the oligoamine is in salt form, it may be said that the salt is not a salt of an anionic surfactant.

[0043] The oligoamines of the present disclosure may have a molecular weight of about 100 to about 1200 Da, or about 100 to about 900 Da, or about 100 to about 600 Da, or about 100 to about 400 Da, preferably about 100 to about 250 Da, and most preferably about 100 to about 175 Da, or even about 100 to about 150 Da. For purposes of this disclosure, molecular weight is determined using the free base form of the oligoamine.

[0044] Those skilled in the art understand how to obtain oligoamines according to the present disclosure. For example, oligoamines according to formula I, where L has m equal to 2, can be obtained by reaction with ammonia and ethylene dichloride, followed by fractional distillation. Common oligoamines obtained are diethylenetriamine (DETA), triethylenetetramine (TETA), and tetraethylenepentamine (TEPA). Through the use of suitable halogen disubstituted alkylenes, other oligoamines according to formula I, where m is equal to 2-6, can be formed.

[0045] Above the pentamines, i.e., hexamines, heptamines, octamines, and possibly nonamines, cogenerically derived mixtures are not expected to separate by distillation and may contain other materials such as cyclic amines, especially piperazines.

[0046] Suitable ethylenic oligoamines according to the present disclosure are commercially available from several chemical suppliers, including Dow, BASF, Huntsman, and Akzo Nobel Corporations.

[0047] Surfactant Systems The treatment composition of the present disclosure includes a surfactant system. The surfactant system includes a linear alkyl benzene sulfonate surfactant (LAS). The surfactant of the surfactant system may be of synthetic origin, natural origin, or a mixture thereof. The surfactant of the surfactant system may be derived from petroleum, waste (such as plastic waste), or renewable resources.

[0048] The surfactant system may consist of one type of surfactant (e.g., LAS). The surfactant system may include multiple surfactants. In particular, a laundry detergent (such as a heavy-duty liquid laundry detergent) may include a surfactant system including an LAS and at least a second surfactant. The surfactant system may include a second surfactant, which may be selected from an alkyl ethoxylated sulfate (AES), a nonionic ethoxylated alcohol, an alkyl ethoxylated carboxylate (AEC), or a mixture thereof.

[0049] The compositions of the present disclosure may comprise from about 1% to about 90% by weight of the composition, or from about 1% to about 80% by weight, or from about 1% to about 70% by weight, or from about 2% to about 60% by weight, or from about 5% to about 50% by weight of the surfactant system. Liquid compositions may comprise from about 5% to about 40% by weight of the composition. Compositions suitable for dense formulations, e.g., dense, liquid, gel, and / or unit dose forms, may comprise from about 25% to about 90% by weight of the composition, or from about 25% to about 70% by weight, or from about 30% to about 50% by weight of the composition.

[0050] 1. Linear alkylbenzene sulfonate (LAS) surfactants The treatment compositions and surfactant systems of the present disclosure may include linear alkyl benzene sulfonate surfactants, otherwise known as "LAS", which are common anionic surfactants used in a variety of cleaning applications and products such as laundry detergents.

[0051] LAS surfactants have alkyl groups in a linear, or straight-chain, arrangement. Linear alkyl groups are typically preferred over branched groups for environmental reasons.

[0052] The alkyl groups may have, on a weight average, from about 9 to about 15 carbon atoms, or from about 11 to about 14, or from about 11 to about 13, or from about 11 to about 12, or about 11.8 carbon atoms. In the last case, the material may be abbreviated as C11.8LAS.

[0053] The LAS may include 2-phenylalkylbenzene sulfonates, in which the benzene ring is attached to an alkyl group at the carbon atom adjacent to the terminal carbon of the substantially linear chain. Thus, the carbon atom attached to the benzene ring has a methyl group and another alkyl group attached to it in the 2-phenylalkylbenzene. Most commonly, and preferably, the sulfonate group is attached to the benzene ring para to the alkyl group. The LAS may contain at least 15% 2-phenyl LAS isomer, or at least 20% 2-phenyl isomer.

[0054] The LAS may be in acid form (referred to as HLAS) and / or salt form. Suitable salts may be formed from alkali metal hydroxides, alkaline earth hydroxides, ammonium hydroxide, alkylammonium hydroxides, alkanolamines such as monoethanolamine, or any other chemical agent known to those skilled in the art that reacts with linear alkylbenzene sulfonates to form water-soluble linear alkylbenzene sulfonates. Alkali metal salts, typically sodium, and / or alkanolamine salts, typically monoethanolamine, of the LAS may be preferred.

[0055] It may be desirable to pre-neutralize the LAS, e.g., prior to combining with the oligoamines of the present disclosure, which may be preferred for improved pH control and / or improved malodor control performance of the oligoamines.

[0056] Linear alkylbenzenes are typically produced on an industrial scale using one of three commercial processes that differ from each other primarily depending on the catalyst system used. One process uses an aluminum trichloride catalyst, another uses a hydrogen fluoride catalyst, and a third uses a solid alkylation catalyst known as DETAL™. Suitable alkylbenzene sulfonates (LAS) can be obtained by sulfonating commercially available linear alkylbenzenes (LABs). Suitable LABs include low 2-phenyl LABs such as those supplied by Sasol under the trade name Isochem™ or by Petresa under the trade name Petrelab™.

The surfactant system may comprise up to about 95%, or up to about 90%, or up to about 80%, or up to about 75%, or up to about 70%, or up to about 60%, or up to about 50%, or up to about 40%, or up to about 30%, up to about 25%, or up to about 20%, or up to about 15%, or up to about 10% by weight of the LAS of the surfactant system.

[0058] The treatment composition may comprise from about 1%, or about 2%, or about 3%, or about 5%, or about 8%, or about 10%, or about 15%, or about 20% by weight of the treatment composition, to about 60%, or about 50%, or about 40%, or about 30%, or about 25%, or about 20% LAS by weight.

[0060] AES, also known as alkyl ether sulfates, alkyl polyethoxylated sulfates, or ethoxylated alkyl sulfates, include water-soluble salts, particularly the alkali metal, ammonium, and alkylol ammonium salts, of organosulfur reaction products having alkyl groups having from about 8 to about 30 carbon atoms in their molecular structure and sulfonic acids and their salts. The term "alkyl" may include the alkyl portion of an acyl group.

[0061] The alkyl group of the AES may have from about 8 to about 30, or from about 10 to about 18, or from about 12 to about 16 carbon atoms. The AES surfactant may be a mixture of alkyl ether sulfates having an average (arithmetic mean) carbon chain length (by weight) in the range of from about 12 to 30 carbon atoms, and in some examples, an average carbon chain length of from about 12 to 15 carbon atoms.

[0062] The AES may have an average (arithmetic mean) degree of ethoxylation of from about 1 mole to about 8 moles, or about 6 moles, or about 5 moles, or about 4 moles, or about 3 moles of ethylene oxide. The AES may have an average (arithmetic mean) degree of ethoxylation of from about 1.8 moles to about 2.5 moles of ethylene oxide. The alkyl ether sulfate surfactant may have a peaked ethoxylate distribution.

[0063] The AES may have an average carbon chain length of from about 10 carbon atoms to about 18 carbon atoms, and an average degree of ethoxylation of from about 1 to about 6 moles of ethylene oxide. Suitable AES surfactants may have an average carbon chain length of from about 12 to about 15 carbon atoms, preferably from about 13 to about 15 carbon atoms, and an average degree of ethoxylation of from about 1 to about 3 moles of ethylene oxide, preferably from about 1.5 to about 2.5 moles of ethylene oxide.

[0136] Test Method Odor reduction test method The following method is used to test the malodor reducing effectiveness of the compositions.

[0137] A. Preparation of 75 grams of odor marker The fatty acids and malodor markers are added according to Table A to a 100 mL glass jar with a Teflon-lined cap and mixed well using a vortex.

[0138] [Table 1]

[0139] B. Preparation of Body Soil Malodor Compositions The specified amount of each material listed in Table 2 is dispensed into a 200 mL glass jar with a Teflon-lined cap. Artificial body soil (ABS) is commercially available from Accurate Product Development (2028 Bohlke Blvd, Fairfield, Ohio 45014).

[0140] [Table 2]

[0141] C. Preparation of Odor Test Fabrics Prepare 16 malodor test fabrics per wash load by applying 300 μL of the body soil malodor composition described in Table B to 2×5 inch white polycotton 50 / 50 (PCW50 / 50) swatches. Add 48 grams of liquid detergent to be tested (see, for example, Example 1, Table 1 below) to a Duet 9200 washer set for a normal cycle, i.e., a wash cycle of 77° F. followed by a rinse cycle of 60° F. Use tap water, e.g., containing ambient concentrations of copper due to copper piping. Wash the malodor test fabrics with 3.9 kg, 50×50 cm clean cotton and polycotton ballast in 7 gpg wash water, then dry in a Maytag double stack tumble dryer set at low temperature for 20 minutes. Place the dried fabrics in a Mylar bag and seal for 24 hours.

[0142] D. Analytical detection of malodors on fabrics Malodor reduction is quantitatively determined by gas chromatography mass spectrometry using an Agilient gas chromatograph 7890B equipped with a mass selective detector (5977B), Chemstation quantitation package, and a Gerstel multipurpose sampler equipped with a solid phase microextraction (SPME) probe, using an ABS / squalene malodor sensor. Calibration standards of 6-methyl-5-hepten-2-one (CAS 110-93-0), trans-2-heptenal (18829-55-5), and 3-methyl-2-butenal (107-86-8) are prepared by dissolving known weights of these materials in light mineral oil (CAS 8020-83-5) (each material available from Sigma Aldrich). The fabric is cut into uniform 2" x 2.5" pieces and placed in a 10 mL headspace crimp vial. The vials are equilibrated for >12 hours before analysis. The following settings are used for the autosampler: incubation temperature of 80° C., incubation time of 90 minutes, sample tray type VT32-10, vial penetration of 22 mm, extraction time of 20 minutes, injection penetration of 54 mm, and desorption time of 300 seconds. The following settings are used for the Front Split / Splitless inlet helium: split mode, temperature of 250° C., pressure of 12 psi, total flow rate of 79.5 mL / min, septum purge flow rate of 3 mL / min, split ratio of 50:1, and GC run time of 22.5 minutes. The following settings are used for the oven: initial temperature of 40° C., heating program of 12° C. / min, temperature of 250° C., and hold time of 5 minutes. Based on the partition coefficients of each component (K at 80° C.), calculate the total nmoles / L for 6-methyl-5-hepten-2-one (K=3353), trans-2-heptenal (K=3434), and 3-methyl-2-butenal (K=1119).

[0143] These values ​​are then summed together (nmol / L) for all three measurements to give the total ABS / squalene marker (nmol / L) for a given test section.

[0144] E. Calculation of odor reduction of oxidation products The % reduction in malodor of oxidation products is given as a percentage comparing the reduction in the amount of selected malodor markers provided by the test composition compared to the reference composition (without oligoamines). Values ​​are determined as follows: Reduction in oxidation products % = (marker ref -marker test ) x 100 / marker ref marker ref and marker test The value of is defined as follows: marker ref = Total ABS / squalene marker (nmol / L) for fabrics washed with formulations without oligoamines (e.g., benchmark or control formulations). marker test = Total ABS / squalene marker (nmol / L) of fabrics washed with formulations containing test oligoamines

[0145] The measured oxidation products are typically considered to be malodors, so the higher the malodor reduction percentage of oxidation products that the composition provides, the more likely the treated fabric will have reduced malodors.Thus, a higher malodor reduction percentage of oxidation products is typically preferred.The disclosed compositions and processes can provide a malodor reduction percentage of oxidation products of at least about 10%, or at least about 20%, or at least about 30%, or at least about 40%, or at least about 50%, or at least about 60%, or at least about 70%, or at least about 80%.

[0146] Odor reduction is also a marker ref and marker test and thus indicating the absolute difference (e.g., delta ABS / squalene oxidation).

[0147] Testing the whiteness reduction test method Test for brightness loss (eg, ΔWI) by following the procedure below.

[0148] A. Preparation of Whiteness Test Fabric Desized cotton, polycotton, and polyester whiteness test fabrics can be ordered from WFK. (WFK Testgewebe GmbH, Christenfeld 10, D-41379 brueggen, Germany). Four of each fabric type (12 fabrics total) are prepared for whiteness testing by washing four times in a Kenmore top loader set at normal wash cycle, 77F wash, 60F rinse, 7 grains per gallon with 48 grams (750 ppm) Tide Free and Clear and 25 grams (390 ppm) Downy Free rinse. Initial whiteness reference measurements are made using a Konika Minolta spectrophotometer and are reported as Initial Whiteness Index CIE. Whiteness Index CIE values ​​are a common index of whiteness and refer to measurements made under D65 illumination, a standard representation of outdoor daylight. A completely reflective non-fluorescent white material has a CIE whiteness of 100. In technical terms, whiteness is a singular index that refers to the relative degree of whiteness of a near-white material under certain lighting conditions. The index is designed so that most people would agree that the higher the whiteness index, the whiter the material.

[0149] B. Whiteness test The fabrics are placed in a 7.57 liter custom wash tank under the conditions summarized in Table 3 below. The fabrics are washed with background soil using 5.65 grams (746 ppm) of detergent (Liquid TIDE®) during the wash cycle, followed by 3 grams (396 ppm) of liquid fabric softener (DOWNY® FREE) during the rinse cycle. After the rinse cycle is completed, all fabrics are removed and placed in a tumble dryer. This is repeated for 10 wash, rinse, and dry cycles. After 10 cycles, the fabrics are measured for whiteness loss using a Konika Minolta spectrophotometer, and the measurements are reported as Final Whiteness Index. The average delta WI (i.e., ΔWI), which represents the difference between the whiteness index measurements between initial and treated, is calculated for each fabric tested and is represented by the following calculation: ΔWI=Initial Whiteness Index after Preparation- Treated Whiteness Index after 10 to 20 Cycles. Typically, ΔWI is a negative value because whiteness tends to decrease after washing with background soil.Whiteness index is reported in the table as ΔΔWI=ΔWI test with oligoamine-ΔWI reference (without oligoamine).ΔΔW is a negative value if whiteness tends to decrease after washing with the test liquid detergent composition containing oligoamine compared to the reference liquid detergent composition not containing oligoamine.Numbers close to zero represent oligoamines that have little effect on fabric yellowing.

Each composition contains a linear alkylbenzene sulfonate (LAS). Some have one or more conventional chelating agents and some contain a linear oligoamine according to the present disclosure.

[0155] Example 2A is a premium type laundry detergent containing a conventional chelating agent (diethylenetetraaminepentaacetic acid (DTPA)). For Examples 2B, 2C, 2D, and 2E, additional amines are added. Example 2B contains an additional amino chelating agent, ethylenediaminedisuccinic acid (EDDS). Examples 2C, 2D, and 2E contain a linear oligoamine of the present disclosure, as detailed in Table 2 below.

[0156] [Table 5] 1 N,N'-bis(3-aminopropyl)ethylenediamine has the following structure:

[0157] [ka]

[0158] The results in Table 2 show the malodor control effectiveness of the linear oligoamines of Examples 2C, 2D, and 2E compared to the composition without the added amine of 2A. Examples 2C, 2D, and 2E also show improved malodor control compared to Example 2B, indicating that the oligoamines perform better than EDDS, a different amine-containing chelating agent.

[0159] Example 3. Malodor control of linear oligoamines in combination with LAS and optionally AES To demonstrate the effect of the linear oligoamine of the present disclosure in combination with LAS and optionally AES, liquid detergent compositions are prepared having the components shown in Table 3A below. Section A does not contain a linear oligoamine according to the present disclosure. Section B contains diethylenetriamine (DETA), a representative linear oligoamine, at a concentration of 0.2% by weight. Additionally, the compositions in each section contain a surfactant system at a concentration of 18.1%, except that the surfactant system contains various ratios of LAS and AES, as shown in Table 3B.

[0160] To test the malodor control effectiveness of DETA in various surfactant systems, fabrics are treated (North American top-loading washing machine, water: 87°F / 7 gpg) and tested for malodor removal as described above. The results of the malodor removal test are shown in Table 3B.

[0161] [Table 6] 3. Diethylenetetraaminepentaacetic acid (DTPA) is supplied by Dow Chemical, Midland, Michigan, USA.

Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate, commercially available as Tinogard TS (BASF). 10. The oligoamine of the present disclosure is diethylenetriamine (DETA).

[0162] [Table 7] 1 Linear alkylbenzene sulfonates with an average aliphatic carbon chain length of C11 to C12, supplied by Stepan (Northfield, Illinois, USA) 2 C12-15 alkyl ethoxy (1.8) sulfate

[0163] As shown in Table 3B, compositions containing a combination of LAS and DETA provide improved malodor reducing effects compared to DETA in a surfactant system without LAS (e.g., Example 3G). Moreover, as the relative amount of LAS in the surfactant system increases (e.g., LAS:AES weight ratios greater than 40:60), the effect becomes more pronounced. This is particularly surprising in view of the general increase in the amount of malodorous oxidation products as the relative amount of LAS increases in the section without DETA (Section A).

[0164] Example 4. Malodor control of linear oligoamines in combination with LAS and optionally non-ionic ethoxylated alcohol surfactants To demonstrate the effect of the linear oligoamine of the present disclosure in combination with LAS and optionally a non-ionic ethoxylated alcohol surfactant, liquid detergent compositions are prepared having the general components as shown in Example 3, Table 3A above. Section A does not contain a linear oligoamine according to the present disclosure. Section B contains diethylenetriamine (DETA), a representative linear oligoamine, at a concentration of 0.2% by weight. Additionally, the compositions in each section contain a surfactant system at a concentration of 18.1%. However, for purposes of Example 4, the surfactant system contains various ratios of LAS and non-ionic ethoxylated alcohol surfactant as shown in Table 4.

[0165] To test the malodor control effectiveness of DETA in various surfactant systems, fabrics are treated (North American top loading machine, water: 87°F / 7 gpg) and tested for malodor reduction as described above. The results of the malodor reduction test are shown in Table 4.

[0166] [Table 8] 1 Linear alkylbenzene sulfonates with an average aliphatic carbon chain length of C11 to C12, supplied by Stepan (Northfield, Illinois, USA) 2Non-ionic ethoxylated alcohol surfactants, specifically C12-14 alcohol ethoxylates with an average degree of ethoxylation of 9, supplied by Huntsman, Salt Lake City, Utah, USA.

[0167] As shown in Table 4, compositions containing a combination of LAS and DETA provide improved malodor reducing effects compared to DETA in a surfactant system without LAS (e.g., Example 4G). Furthermore, as the relative amount of LAS in the surfactant system increases (e.g., LAS:NI weight ratios of 40:60 or greater), the malodor reducing effects become more pronounced.

[0168] Example 5. Malodor control of linear oligoamines in combination with LAS and alkyl ethoxylated carboxylate (AEC) surfactants To demonstrate the effect of the linear oligoamines of the present disclosure in combination with LAS and AEC surfactants, liquid detergent compositions are prepared having the general ingredients as shown in Example 3, Table 3A above. Section A does not contain a linear oligoamine according to the present disclosure. Section B contains diethylenetriamine (DETA), a representative linear oligoamine, at a concentration of 0.2% by weight. Additionally, the compositions in each section contain a surfactant system at a concentration of 18.1%. However, for purposes of Example 5, the surfactant system contains LAS and alkyl ethoxylated carboxylate (AEC) surfactants in various ratios as shown in Table 5.

[0169] The fabrics are treated in a North American top-loading automatic washing machine (water: 30.6° C., 7 gpg). The malodor reduction effect is shown in Table 5 as the percentage reduction in oxidation products for fabrics treated in the second category (category B, with DETA) compared to the first category (category A, without DETA).

[0170] [Table 9] 1Linear alkylbenzene sulfonates having an average aliphatic carbon chain length of C11-C12 supplied by Stepan (Northfield, Illinois, USA). 2 C12-C14 alcohol polyethylene glycol ether carboxylic acid (Marlowet 4541 supplied by Sasol).

[0171] As shown in Table 5, Example 5D, which contains the highest relative amount of LAS, provides the greatest malodor reduction effect.

[0172] Example 6. Effect of alkylation To demonstrate the effectiveness that the oligoamines of various degrees of alkylation described herein can have on malodor reduction effects, the following molecules are tested at the concentrations provided according to the test method set forth above. The oligoamines are added to a liquid detergent containing LAS, AES, and a non-ionic surfactant. The test is performed in a North American front-loading automatic washing machine.

[0173] The percentage reduction in oxidation products relative to a reference composition is shown for each compound in Tables 6A and 6B below.

[0174] [Table 10] As shown by the above structures, Example 6B is characterized by a terminal primary amine, Example 6C is characterized by a terminal secondary amine, and Example 6D is characterized by a terminal tertiary amine. As shown in Table 6A, Examples 6B to 6D each have a malodor reduction effect, with Example 6B having the greatest malodor reduction effect.

[0175] [Table 11]

[0176] As shown in Table 6B, Example 6F provides the greatest relative malodor reduction.

[0177] Example 7. Oligoamine Brightness To demonstrate the effectiveness that oligoamines (and their % concentration) can have on whiteness, certain amines are added to North American liquid TIDE® (a commercial heavy-duty liquid laundry detergent) as shown in Table 7. The detergent composition includes LAS, AES, and nonionic surfactants. Various fabrics (cotton, polycotton, and polyester) are treated under North American conditions for 10 wash cycles with the composition.

[0178] After 10 cycles, the brightness loss is determined according to the ΔWI test, as described above in the Test Methods section. The results are shown in Table 7. A negative number indicates brightness loss, with a larger magnitude of the number indicating a larger brightness loss (e.g., -10 indicates a larger brightness loss than -5). Preferably, the brightness loss is between 0 and -5, or between 0 and -4. A larger magnitude of brightness loss indicates that the product may be less suitable for consumer use.

[0179] [Table 12]

[0180] As shown in Table 7, the presence of amines can result in brightness loss upon multiple treatments. However, the brightness loss caused by amine concentrations of, for example, less than 0.1 wt. % (see Trials 7B and 7C) is relatively acceptable to manufacturers. In comparison, Trial 7D, which contains a DETA concentration of greater than 1%, exhibits brightness loss that is considered less favorable. It is believed that alkylated oligoamines can further improve brightness loss and / or allow for the formulation of higher concentrations of oligoamines while maintaining brightness loss within an acceptable range.
