Description

Technical Field

[0001] This disclosure relates to treatment compositions comprising a surfactant system and an oligoamine. This disclosure also relates to related methods of using and preparing such compositions. Background Technology

[0002] Many treatment methods, such as laundry methods, are designed to remove dirt from surfaces such as fabrics. Some dirt can cause unpleasant odors on fabrics, which can persist or even form after the treatment process is complete. Therefore, manufacturers of consumer and industrial cleaning products are constantly seeking to provide compositions and methods that offer improved odor control.

[0003] Certain polyamines or oligoamines are known to be used alone in detergent compositions. These polyamines or oligoamines can contribute to certain beneficial cleaning effects, such as grease removal. However, such compounds can cause discoloration, such as yellowing of fabrics.

[0004] There is a need for compositions that provide improved odor control, especially if such compositions can utilize oligoamines more effectively. Summary of the Invention

[0005] This disclosure relates to treatment compositions having a certain oligoamine and / or its salt and a specific surfactant system.

[0006] For example, this disclosure relates to a treatment composition comprising an oligoamine and / or its salt and a surfactant system, wherein the oligoamine is present in an amount of about 0.01% to 3.0% by weight of the treatment composition, wherein the oligoamine has a structure according to Formula I:

[0007]

[0008] Each L is independently -(C m H 2m )-, where for each L, the subscript m is an integer from 2 to 6, n is an integer from 1 to 10, and R 1 -R 5 Each of them is independently selected from H and C1-C4 alkyl groups, typically where R 1 -R 5 At least one of them is H; and the surfactant system contains a linear alkylbenzene sulfonate (LAS) surfactant.

[0009] This disclosure also relates to a method of treating a surface, the method comprising the steps of: (a) providing a surface, preferably a fabric, more preferably a fabric contaminated with sebum, and (b) optionally contacting the surface with the composition described in this disclosure in the presence of water.

[0010] This disclosure also relates to the use of surfactant systems in fabric care compositions to improve the beneficial effects of oligoamines and / or their salts on odor control of target fabrics, the surfactant system comprising a linear alkylbenzene sulfonate surfactant, and wherein the oligoamine has a structure according to Formula I as described herein. Detailed Implementation

[0011] This disclosure relates to treatment compositions comprising oligoamines and linear alkylbenzene sulfonate (LAS) surfactants. Such oligoamines have been found to provide surprisingly beneficial effects for odor control, for example, in the washing of fabrics, and these beneficial effects can be improved in compositions comprising LAS.

[0012] Unbound by theory, it is believed that metal ions in the treatment solution, such as copper ions (e.g., Cu), 2+ This can facilitate the decomposition of certain contaminants, such as sebum, on the target surface. Such decomposition can release volatile odorous compounds into the air. It is believed that the oligoamines of this disclosure can chelate and multivalently chelate copper ions in the treatment solution, thereby inhibiting the release of such odorous compounds.

[0013] Furthermore, it has been found that the combination of oligoamines and LAS surfactants of the present invention can provide surprisingly good odor control benefits. Without being bound by theory, it is believed that the deposition of oligoamines on the target surface can be facilitated by LAS surfactants, for example, through hydrophobic interactions. The more effective the oligoamine deposition, the more it can inhibit the decomposition of odor-causing dirt. The mechanism by which such beneficial effects are produced is not intuitive, as oligoamines and anionic surfactants such as LAS typically provide beneficial effects by removing dirt from the surface. LAS can be part of a surfactant system that may contain one or more additional surfactants.

The oligoamines according to this disclosure comprise amine functional groups, which may be primary, secondary, or tertiary amines linked by specific alkylene groups. Without being bound by theory, it is believed that the oligoamines of this disclosure are highly suitable for chelating certain metals, such as copper (Cu). 2+ Furthermore, such chelation can provide beneficial effects for odor control.

[0033] The treatment compositions of this disclosure comprise about 0.01%, or about 0.05%, to about 3.0%, or about 2.0%, or about 1.0%, or about 0.75%, or about 0.5%, or about 0.4%, or about 0.3%, or about 0.2%, or about 0.15%, or about 0.1% of oligoamine by weight of the treatment composition. For the purposes of this disclosure, the weight percentage of linear oligoamines is calculated using the weight in the form of free base. Relatively low contents (e.g., less than about 1%, or less than about 0.5%, or less than about 0.2%, or less than about 0.1%) of oligoamines may be preferred depending on the intended use and / or formulation, because amines can cause certain surface discoloration / yellowing.

[0034] The oligoamines disclosed herein can be considered as linear oligoamines. "Linear" means that there are no additional amine-containing side chains grafted onto the oligoamine backbone represented by Formula I. However, it should be understood that linear oligoamines may, in at least some cases, have alkyl groups, such as methyl or ethyl groups, attached to the oligoamine backbone.

[0035] The oligoamines disclosed herein may have a structure according to Formula I:

[0036]

[0037] in

[0038] Each L is independently -(C m H 2m )-, where for each L, the subscript m is an integer from 2 to 6, preferably m is 2 or 3, more preferably m is 2 (e.g., ethylene group);

[0039] n is 1 to 10 (i.e., triamine, tetraamine, pentaamine, hexaamine, heptaamine, etc.), preferably 1 to 5, more preferably 1 to 3, even more preferably 1 to 2, and most preferably an integer of 1; and

[0040] Where R 1 -R 5 Each of them is independently selected from H and C1-C4 alkyl groups, preferably H and methyl (i.e., C1 alkyl). It should be understood that when n is greater than 1, each R 5 Independently selected from the provided groups, although each R 5 They can be the same.

[0041] For each L, the subscript m can be an integer from 2 to 6, wherein for each of the two L groups directly attached to the common N atom, the subscript m is 2 or 3, preferably 2. It is believed that even if the other L groups are relatively large (e.g., m is greater than 2), placing two such L groups adjacent to the common N atom will be beneficial for improving metal chelation.

[0042] R 1 -R 5 Each of them can be H. R 5 It can be methyl. R 5 It can be H. R 1 and R 3 One or both of them can be methyl. R 1 and R 3 It can be methyl, and R 2 and R 4 Both can be hydrogen. R 1 -R 5 Each of them can be a methyl group. Preferably, R 1 -R 5 At least one of them is H, and even more preferably, R. 1 -R 4 At least one of them is H. R 1 -R 4 It can be H, and R 5 It can be independently selected from H and C1 alkyl groups.

[0043] The compositions of the present invention may comprise oligoamines having a structure according to Formula I above, wherein L, m, n and R 1 -R 5As defined above, the condition is that if n equals 1, then R5 is selected from H and the portion having 1 to 10 carbon atoms, or 1 to 6 carbon atoms, or 1 to 4 carbon atoms.

[0044] Depending on the desired product type and / or overall beneficial effect space, the formulator may select oligoamines, particularly those containing primary, secondary, and / or tertiary nitrogen atoms at the terminal positions. Without being bound by theory, it is believed that the presence of primary nitrogen atoms in the oligoamines of the present invention provides a beneficial effect of improved odor control, believed to be due to improved chelation efficiency and / or coordination with target surfaces such as fabrics. Also without being bound by theory, it is believed that tertiary nitrogen atoms in the oligoamines of the present invention can lead to less interaction with other substances in the treatment composition, such as reactions with certain fragrance substances, which could otherwise lead to reactions (e.g., Schiff base reactions) and subsequent color changes in the liquid product.

These (partially)protonated oligoamines are also considered to be within the scope of this disclosure. When the oligoamine is in salt form, the salt may not be a salt of an anionic surfactant.

[0050] The oligoamines disclosed herein may have a molecular weight between about 100 Da and about 1200 Da, or about 100 Da and about 900 Da, or about 100 Da and about 600 Da, or about 100 Da and about 400 Da, preferably between about 100 Da and about 250 Da, most preferably between about 100 Da and about 175 Da, or even between about 100 Da and about 150 Da. For the purposes of this disclosure, the molecular weight of the oligoamine is determined using the free base form.

[0051] Those skilled in the art will know how to obtain the oligoamines according to this disclosure. For example, an oligoamine according to Formula I (where L has m equal to 2) can be obtained by a reaction involving ammonia and ethylene dichloride, followed by fractional distillation. Common oligoamines obtained are diethylenetriamine (DETA), triethylenetetramine (TETA), and tetraethylenepentamine (TEPA). Other oligoamines according to Formula I can be formed by using suitable halogenated dialkylene groups, where m equals 2 to 6.

[0189] Odor Reduction Test Method

[0190] The following methods were used to test the composition's beneficial effect in reducing odor.

[0191] A. Preparation of 75 grams of odor marker

[0192] According to Table A, add fatty acids and odor markers to a 100ml wide-mouth glass flask with a Teflon-lined lid and mix thoroughly using a vortex.

[0193] Table A: Compositions of Odor Markers

[0194] Isovalerate 503-74-2 12.00 9.0 Undecaneal 112-44-7 0.20 0.15 Undecanoic acid 112-37-8 62.80 47.1 skatole 83-34-1 1.00 0.75 Decanoic acid 334-48-5 22.00 16.5 Ethyl undecanoate 627-90-7 2.00 1.5

[0195] B. Preparation of body odor composition

[0196] Each material will be supplied in the specified amounts according to Table B into 200 mL wide-mouth glass vials with Teflon-lined caps. Artificial body scum (ABS) is commercially available from Accurate Product Development (2028 Bohlke Blvd, Fairfield, OH 45014).

[0197] Table B: Compositions for Body Feces and Malodor

[0198] Odor markers (from Table A) 17.1 Artificial body smegma (ABS) 15.8 Dipropylene glycol monomethyl ether (CAS: 34590-94-8) 105 Squalene (CAS No. 111-02-4) 15.8

[0199] C. Preparation of odor test fabric

[0200] Sixteen odor test fabrics per wash load were prepared by applying 300 μl of the body odor composition described in Table B to degummed 2×5-inch white polyester / cotton 50 / 50 (PCW50 / 50) samples. 48 g of the liquid detergent to be tested (see Table 1, for example, in Example 1 below) was added to a Duet 9200 washing machine set to normal cycle; a 77℉ wash cycle followed by a 60℉ rinse cycle. Tap water was used, which contained ambient levels of copper due to, for example, the copper piping system. The odor test fabrics were washed in 7 g pg wash water with 3.9 kg of 50×50 cm cleaning cotton and polyester / cotton ballast, and then dried in a Maytag double-stacked tumble dryer set to low for 20 minutes. The dried fabrics were placed in polyester film bags and sealed for 24 hours.

[0201] D. Odor analysis and detection on fabrics

[0202] Odor reduction using an ABS / squalene odor sensor was quantitatively determined by gas chromatography-mass spectrometry (GC-MS) using an Agilent 7890B gas chromatograph equipped with a mass-selective detector (5977B), a Chemstation quantification kit, and a Gerstel multi-purpose sampler with a solid-phase microextraction (SPME) probe. Calibration standards for 6-methyl-5-hepten-2-one (CAS 110-93-0), trans-2-heptenal (18829-55-5), and 3-methyl-2-butenal (107-86-8) were prepared by dissolving known weights of these materials in light mineral oil (CAS 8020-83-5) (each material was purchased from Sigma-Aldrich). Fabric was cut into uniform 2-inch by 2.5-inch pieces and placed in 10 mL headspace vials. The vials were equilibrated for more than 12 hours prior to analysis. Use the following settings in the autosampler: incubation temperature 80°C, incubation time 90 min, VT32-10 sample tray type, 22 mm vial breakthrough, 20 min extraction time, 54 mm injection breakthrough, and 300 s desorption time. For the split / splitless inlet helium, use the following settings: split mode, 250°C temperature, 12 psi pressure, 79.5 mL / min total flow rate, 3 mL / min diaphragm purge flow rate, 50:1 split ratio, and 22.5 min GC run time. Use the following settings in the oven: initial temperature 40°C, heating program 12°C / min, 250°C temperature, and 5 min holding time. Calculate the total nMol / L for 6-methyl-5-hepten-2-one (K = 3353), trans-2-heptenal (K = 3434), and 3-methyl-2-butenal (K = 1119) based on the partition coefficient (K at 80°C).

[0203] These three measurements (in nmol / L) are added together to provide the total ABS / squalene marker (nmol / L) for a given test group.

[0204] E. Calculation of Odor Reduction Oxidation Products

[0205] The odor reduction percentage (% of oxidized products) is provided as a percentage, comparing the reduction in the amount of selected odor markers provided by the test composition to that of a (non-oligoamine) reference composition. This value is determined as follows:

[0206] Oxidation product reduction % = (marker) ref - markers test )×100 / marker ref

[0207] markers ref and markers test The value is defined as follows:

[0208] markers ref = Total ABS / squalene marker (nmol / L) of fabrics washed with a formulation that does not contain oligoamines (e.g., a reference or control formulation).

[0209] markers test =Total ABS / squalene marker (nmol / L) of fabric washed with a formulation containing the tested oligoamine.

[0210] Since the measured oxidation products are generally considered to be malodorous, it is believed that the greater the reduction in oxidation products provided by the composition, the less malodor the treated fabric may have. Therefore, a larger malodor reduction oxidation product % value is generally preferred. The compositions and methods disclosed herein can provide malodor reduction oxidation product % values ​​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%.

[0211] A reduction in odor can also be reported by markers. ref and Markers test The differences between them show absolute differences (e.g., ΔABS / squalene oxidation).

[0212] Whiteness loss test method test

[0213] Test whiteness loss (e.g., ΔWI) according to the following procedure.

[0214] A. Preparation of fabrics for whiteness testing

[0215] Degummed cotton, polyester-cotton blends, and polyester whiteness test fabrics were available from WFK (WFK Testgewebe GmbH, Christenfeld 10, D-41379Brüggen, Germany). Four fabrics of each type (a total of 12 fabrics) were prepared for whiteness testing by washing four times in a Kenmore top-loading washer set to normal wash cycle, 77°F wash, 60°F rinse, 7 grains / gallon, with 48 g (750 ppm) Tide Free and Clear and 25 g (390 ppm) Downy Free rinse solution. Initial whiteness reference measurements were performed using a Konica Minolta spectrophotometer and reported as the initial whiteness index (CIE). The CIE value is a common whiteness index and refers to measurements taken under D65 illumination (the standard representation of outdoor daylight). For perfectly reflective, non-fluorescent white materials, the CIE whiteness will be 100. In technical terms, whiteness is a single numerical index that refers to the relative degree of whiteness of a near-white material under specific lighting conditions. This index is designed so that most people would agree that the higher the whiteness index, the whiter the material.

[0216] B. Whiteness Test

[0217] Under the conditions summarized in Table 3 below, place the fabric in a 7.57-liter custom wash tub. During the wash cycle, use 5.65 grams (746 ppm) of detergent (liquid). Wash the fabric with background dirt, then rinse with 3 grams (396 ppm) of liquid fabric softener in the rinse cycle. (Free) Wash. Once the rinsing cycle is complete, remove all fabrics and place them in a tumble dryer. Repeat the wash, rinse, and dry cycle 10 times. After 10 cycles, measure the whiteness loss of the fabrics using a Konica Minolta spectrophotometer and report the measurements as the final whiteness index. Calculate the average ΔWI (i.e., ΔWI) for each test fabric (representing the difference between the initial and treated whiteness index measurements) and express it as follows: ΔWI = Initial whiteness index after preparation - Treated whiteness index after 10 to 20 cycles. Typically, ΔWI is negative because whiteness tends to decrease after washing with background dirt. The whiteness index is reported in the table as Δ ΔWI = ΔWI tested with oligoamines - ΔWI REF (without oligoamines). If whiteness tends to decrease after washing with a test liquid detergent composition containing oligoamines compared to a reference liquid detergent composition that does not contain oligoamines, then Δ ΔWI is negative. A number close to zero will indicate oligoamines that have little effect on yellowing of the fabric.

[0241] Example 2A is a high-quality laundry detergent containing a conventional chelating agent (diethylenetetraminepentaacetic 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 linear oligoamines of this disclosure, detailed in Table 2 below. The reduction in oxidation products of the compositions was tested according to the test methods provided above. The results are shown in Table 2.

Examples 2C, 2D, and 2E also showed improved odor control compared to Example 2B, indicating that the oligoamines performed better than EDDS, a different amine-containing chelating agent.

[0247] Example 3: Odor control of linear oligoamines combined with LAS and optional AES

[0248] To demonstrate the beneficial effects of the linear oligoamines of this disclosure combined with LAS and optionally with AES, liquid detergent compositions having the components shown in Table 3A below were prepared. Group A does not contain the linear oligoamines according to this disclosure; Group B contains 0.2% by weight of diethylenetriamine (DETA), a representative linear oligoamine. Furthermore, the compositions in each group contain a surfactant system at an amount of 18.1%. However, the surfactant system contains various ratios of LAS and AES, as shown in Table 3B.

[0249] To test the beneficial effects of DETA on odor control in various surfactant systems, fabrics were treated as described above (North American top-loading washing machine, water: 87℉ / 7gpg) and odor removal was tested. The results of the odor removal tests are shown in Table 3B.

[0264] 2. C12-15 alkylethoxy(1,8) sulfate

[0265] As shown in Table 3B, compositions containing a combination of LAS and DETA provide improved odor reduction benefits compared to LAS-free surfactant systems (e.g., Example 3G). Furthermore, the beneficial effects become more pronounced as the relative amount of LAS in the surfactant system increases (e.g., an LAS:AES weight ratio greater than 40:60). This is particularly surprising considering that the amount of odor oxidation products generally increases with increasing relative LAS in the DETA-free group (Group A).

[0266] Example 4: Combinations of linear oligoamines with LAS and optionally with nonionic ethoxylated alcohol surfactants. Combination of odor control

[0267] To demonstrate the beneficial effects of combining the linear oligoamines of this disclosure with LAS, and optionally with nonionic ethoxylated alcohol surfactants, liquid detergent compositions having the general composition shown in Table 3A of Example 3 above were prepared. Group A does not contain the linear oligoamines according to this disclosure; Group B contains 0.2% by weight of diethylenetriamine (DETA), a representative linear oligoamine. Furthermore, the compositions of each group contain a surfactant system at an amount of 18.1%. However, for the purposes of Example 4, the surfactant system contains LAS and nonionic ethoxylated alcohol surfactants in various ratios, as shown in Table 4.

[0268] To test the beneficial effects of DETA on odor control in various surfactant systems, fabrics were treated as described above (North American top-loaded, water: 87℉ / 7gpg) and odor reduction was tested. The results of the odor reduction test are shown in Table 4.

[0269] Table 4 :

[0273] As shown in Table 4, compositions containing a combination of LAS and DETA provide improved odor reduction benefits compared to LAS-free surfactant systems (e.g., Example 4G). Furthermore, the odor reduction benefits become more pronounced with increasing relative amounts of LAS in the surfactant system (e.g., a LAS:NI weight ratio of 40:60 or greater).

[0274] Example 5: Adverse effects of combinations of linear oligoamines with LAS and alkyl ethoxylated carboxylates (AEC) surfactants Odor control

[0275] To demonstrate the beneficial effects of combining the linear oligoamines of this disclosure with LAS and AEC surfactants, liquid detergent compositions having the general composition shown in Table 3A of Example 3 above were prepared. Group A does not contain the linear oligoamines according to this disclosure; Group B contains 0.2% by weight of diethylenetriamine (DETA), a representative linear oligoamine. Furthermore, the compositions of each group contain the surfactant system at an amount of 18.1%. However, for the purposes of Example 5, the surfactant system contains LAS and alkyl ethoxylated carboxylate (AEC) surfactants in various ratios, as shown in Table 5.

[0276] Fabrics were treated in a top-loading automatic washing machine (water: 30.6°C, 7 gpg) in North America. The beneficial effects of odor reduction are provided in Table 5 as a percentage reduction in oxidative products on textiles treated in Group 2 (Group B, with DETA) relative to Group 1 (Group A, without DETA).

[0280] 2. C12-C14 alcohol polyethylene glycol ether carboxylic acid (Marlowet 4541, supplied by Sasol)

[0281] As shown in Table 5, Example 5D, which includes the maximum relative amount of LAS, provides the greatest odor reduction benefit.

[0282] Example 6: Effects of Alkylation

[0283] To demonstrate the effect of various degrees of alkylation of the oligoamines described in this invention on the beneficial effect of odor reduction, the following molecules were tested at the provided levels according to the test methods described above. The oligoamines were added to a liquid detergent containing LAS, AES, and a nonionic surfactant. Tests were conducted in a North American front-loading automatic washing machine.

[0284] The percentage reduction in oxidation products for each compound relative to the reference composition is provided in Tables 6A and 6B below.

[0285] Table 6A :

[0286]

[0287] As shown in the structures above, Example 6B is characterized by a terminal primary amine, Example 6C by a terminal secondary amine, and Example 6D by a terminal tertiary amine. As shown in Table 6A, Examples 6B-6D each provide a beneficial effect of odor reduction, with Example 6B providing the largest relative odor reduction.

[0288] Table 6B :

[0289]

[0290]

[0291] As shown in Table 6B, Example 6F provides the largest relative reduction in odor.

[0292] Example 7: Effect of oligoamines on whiteness

[0293] To demonstrate the effect of oligoamines (and their percentage content) on whiteness, certain amines were added to the North American liquids provided in Table 7. (Commercially available heavy-duty liquid laundry detergent). The detergent composition contains LAS, AES, and nonionic surfactants. Various fabrics (cotton, cotton-polyester blends, and polyester) were treated with these compositions for ten wash cycles under North American conditions.

[0294] After ten cycles, whiteness loss was determined according to the ΔWI test provided in the Test Methods section above. The results are provided in Table 7. Negative numbers indicate whiteness loss, with larger values ​​indicating greater whiteness loss (e.g., -10 indicates a whiteness loss greater than -5). Whiteness loss is preferably between 0 and -5, or between 0 and -4. Larger whiteness loss values ​​indicate that the product may be suboptimal for consumer use.

[0295] Table 7 :

[0296]

[0297] As shown in Table 7, the presence of amines may result in a loss of whiteness with repeated processing. However, the whiteness loss provided by, for example, less than 0.1% by weight of amine content (see Tests 7B and 7C) is relatively acceptable to manufacturers. By comparison, Test 7D (which contains more than 1% DETA) shows what is believed to be a suboptimal whiteness loss. Alkylation of oligoamines is believed to further improve whiteness loss and / or allow oligoamines to be formulated at relatively high levels while keeping whiteness loss within acceptable limits.
