Abstract
The present invention provides a liquid laundry detergent with improved malodor control benefits containing from about 0.001 wt% to about 5 wt% of a hindered phenol antioxidant and a specific surfactant system comprising both a Nonionic (NI) surfactant and an Anionic (AI) surfactant at a NI to AI weight ratio of from about 1 to 20.
Description
Technical Field
The present invention relates to cleaning compositions and in particular to liquid laundry detergent compositions for treating fabrics which have improved malodour control benefits.
Background
Laundry washing processes are designed to remove soils and stains from fabrics. Some soils and stains can produce malodors on fabrics. In some cases, these malodors may persist even after laundry washing operations.
There is a continuing need to provide laundry detergent products with improved malodor control and reduced benefit without increasing the total surfactant content therein or enlarging the environmental "footprint".
Disclosure of Invention
It is a surprising discovery of the present invention that when a liquid laundry detergent composition employs a hindered phenolic antioxidant in combination with a specific surfactant system, i.e., in one instance comprising Nonionic (NI) and Anionic (AI) surfactants at a relatively high weight ratio of NI to AI, the resulting malodor control and reduction benefits are further improved when compared to a liquid laundry detergent composition comprising the same hindered phenolic antioxidant but comprising a different surfactant system (e.g., having a lower weight ratio of NI to AI). Furthermore, the presence of hindered phenolic antioxidants in the liquid laundry detergent compositions of the present invention may further improve perfume release from such compositions.
In one aspect, the present invention relates to a liquid laundry detergent composition comprising:
a) about 0.001 wt% to about 5 wt% of a hindered phenol antioxidant;
b) about 5% to about 60% by weight of one or more Nonionic (NI) surfactants; and
c) from about 1% to about 45% by weight of one or more Anionic (AI) surfactants;
while the NI to AI weight ratio is in the range of 1 to 20.
In a particularly preferred embodiment, the present invention relates to a liquid laundry detergent composition comprising:
1) from about 0.02 wt% to about 0.5 wt% of a hindered phenolic antioxidant selected from the group consisting of: c of 3, 5-bis (1, 1-dimethylethyl) -4-hydroxy-benzenepropanoic acid 1 -C 22 Linear alkyl esters and mixtures thereof;
2) from about 10% to about 40% by weight of a nonionic surfactant (NI) selected from the group consisting of: c with a weight average degree of ethoxylation in the range of about 7 to about 10 8 -C 18 Alkyl ethoxylated alcohols and mixtures thereof; and
3) about 5 wt% to about 20 wt% C 10 -C 20 Linear alkyl benzene sulphonate (LAS) and C having a weight average degree of ethoxylation in the range of from about 1 to about 3 10 -C 20 Linear or branched Alkyl Ethoxy Sulfates (AES),
wherein the weight ratio of NI to LAS + AES is in the range of about 1.5 to about 8.

In one aspect, the present invention relates to a method of treating a fabric using the above liquid laundry detergent composition, the method comprising the steps of: (i) providing a liquid laundry detergent composition as described above; (ii) forming a laundry liquor by diluting the liquid laundry detergent composition with water; (iii) washing the fabric in a laundry wash liquor; and (iv) rinsing the fabric in water.
The machine washing process may comprise treating soiled fabrics in a top-loading or front-loading automatic or semi-automatic washing machine with an aqueous wash solution having dissolved or dispersed therein an effective amount of a liquid laundry cleaning composition according to the present invention. By "effective amount" of a liquid laundry detergent composition is meant that from about 10g to about 300g of the product is dissolved or dispersed in a volume of wash solution of from about 5L to about 65L. The water temperature may range from about 5 ℃ to about 100 ℃. The ratio of water to soiled fabric may range from about 1:1 to about 30: 1. The liquid laundry detergent composition may be employed in solution at a concentration of from about 200ppm to about 15,000 ppm. Detergent dosage levels may also vary depending not only on the type and severity of the soil and stains, but also on the wash water temperature, the volume of wash water and the type of washing machine (e.g., top-loading, front-loading, vertical axis japanese-style automatic washing machines).
The liquid laundry detergent compositions herein are useful for washing fabrics at reduced wash temperatures. These methods of laundering fabrics comprise the steps of: delivering a laundry detergent composition to water to form a wash liquor, and adding the washed fabric to the wash liquor, wherein the wash liquor has a temperature of from about 0 ℃ to about 20 ℃, or from about 0 ℃ to about 15 ℃, or from about 0 ℃ to about 9 ℃. The fabric may be contacted with the water before, after, or simultaneously with the contacting of the liquid laundry detergent composition with the water.
Hand wash/soak methods and hand wash and semi-automatic washing machine combinations are also included.
Test method
A. Sensory testing for malodor reduction/removal
To evaluate malodor and freshness, sensory tests were performed as follows. The sensory panelists consisted of at least 5 panelists. The panelists must wear safety glasses, lab coats and disposable gloves. The panelists' noses were unable to directly contact the test fabric during the evaluation. Panelists must follow appropriate rules to avoid nasal saturation and maintain good assessment quality.
1) Preparation of the Fabric
The test fabric was a 100% cotton terry cloth with dimensions 30cm x 30 cm. The test fabric will be checked to ensure that there are no stains and that it is a new towel before testing. The fabric is then washed in an elution operation to remove the starch from the towel. The elution wash test has two steps: the first step was washed and rinsed three times with powder detergent (without microcapsule perfume detergent) at 40 ℃ test conditions, then the second step was washed and rinsed three times with water at 40 ℃.
2) Preparation of 0.15% malodorous soil solution
A 0.15% malodorous soil solution was prepared by mixing the malodorous mixture and Artificial Body Soil (ABS) in this ratio: the 1% malodorous mixture was 105ml and the ABS solution was 14.525ml, ethanol was 581ml, for a total of 700ml for the 1 test.
Malodorous mixtures were prepared by dissolving malodors in ethanol (CAS #:64-17-,5) with the following composition. Artificial body fouling (ABS) can be detected by Accurate Product Development; 2028Bohlke Blvd, Fairfield, OH 45014 is commercially available. The operation should be carried out in a fume hood.
Table a: malodor mixture composition
| Material | CAS number |
| Capric acid | 334-48-5 |
| Undecanoic acid | 112-37-8 |
| Undecanal aldehyde | 112-44-7 |
| Squalene | 111-02-4 |
| 6-methyl-5-hepten-2-one | 110-93-0 |
| Phenol and its salts | 108-95-2 |
| Isovaleric acid | 503-74-2 |
| Skatole essence | 83-34-1 |
| Triethylamine | 121-44-8 |
| 3-methyl-3-sulfonylhex-1-ol | 307964-23-4 |
3) Application of malodorous soil solution to test fabrics
This process was operated in a fume hood. The test towel fabric was uniformly cut into 4 parts (1/4) for test pieces. The towels were soaked in tap water and excess water was removed by spin drying with a washing machine for 3 min. For the test piece (1/4 size fabric), 5ml of the cocktail solution (0.15% malodorous soil solution) was applied by pipette on the front side and 5ml on the back side of the test piece. For ballasted malodorous tarnished towels (full size fabric), 20ml of the blend solution (0.15% malodorous soil solution) was applied on the front and 20ml on the back. The test piece was wrapped with an aluminum sheet and sealed by folding the edges of the aluminum sheet (test piece x 4 wrapped together). The test pieces wrapped with aluminum sheets were tapped for 5 min. The wrapped towels were packed in plastic bags, kept in plastic boxes, and incubated for 7 days in a 40 ℃ 'CTCH or 40 ℃' calibrated incubator. The aluminum sheet was then removed and the towel was dried in a fume hood for about 3-4 hours. After 3-4 hours of drying, the fabric was checked for malodor and ready for use.
4) Washing operation and sensory evaluation for test fabrics
The test fabric pieces (1/4 cut towels) were used for washing by detergent and evaluated for malodor reduction/removal effects. For the test panel (typically 3 panels), 3 test fabric pieces (1/4 size x 3) were used for malodor assessment, and 3 full size towels with malodor solution applied were used for ballast, the others balanced to 3kg by a clean T-shirt. For the control panel, 15 test fabric pieces (1/4 size × 15) were used for malodor assessment and balanced to 3kg by a clean T-shirt. The washing test was performed in a washing machine with standard test conditions.
Reference is also made to laundry detergents included in the above method. The reference may be one of the laundry detergents to be tested. The malodor score of the sample relative to the reference was determined by the panelist according to the following sensory scale (9 point scale):
table B: sensory Scale definition
The test fabrics were evaluated by at least 5 qualified DoD panelists. 3 replicates were performed per pair (3 sets of pairs from different fabrics), each pair potentially being evaluated by up to 3 panelists. After the first panelist completed the evaluation, the 2 nd panelist began the evaluation. All test fabrics were held tightly in plastic bags until panelist 2 completed the evaluation. Panelists must complete the evaluation within 20 min. If they fail to complete the assessment of all pairs within 20min, they need to rest for at least 20min and then assess the remaining pairs. There were three time points to evaluate the fabric: after washing (which is within 1-2 hours after washing), after drying (which is within the next day after washing), rewetting (which is within the same day as after evaluation of drying and within 1-2 hours after spraying water on the test fabrics). Rewet refers to the application of water on a dry test fabric and it simulates wiping a wet hand on a towel.
B. Quantitative test for malodor reduction
The following methods were used to test the malodor reduction benefits of the compositions.
Fatty acids and malodor markers were added to a 100ml glass jar with a Teflon-lined lid according to table C and mixed thoroughly using a vortex.
Table C: malodor marker compositions
| Material | CAS number | Composition% | Required weight (g) |
| Isovaleric acid | 503-74-2 | 12.00 | 9.0 |
| Undecanal aldehyde | 112-44-7 | 0.20 | 0.15 |
| Undecanoic acid | 112-37-8 | 62.80 | 47.1 |
| Stink-eliminating agent | 83-34-1 | 1.00 | 0.75 |
| Capric acid | 334-48-5 | 22.00 | 16.5 |
| Undecanoic acid ethyl ester | 627-90-7 | 2.00 | 1.5 |
Body scale malodor compositions were then prepared by adding the specific amounts of each material according to table D to a 200mL glass jar with a Teflon-lined lid. Artificial body fouling (ABS) can be detected by Accurate Product Development; 2028Bohlke Blvd, Fairfield, OH 45014 are commercially available.
Table D: body dirt malodor composition
| Material | Weight (g) |
| Malodor marker (from watch C) | 17.1 |
| Artificial body dirt (ABS) | 15.8 |
| Dipropylene glycol monomethyl ether (CAS: 34590-94-8) | 105 |
| Squalene (CAS number 111-02-4) | 15.8 |
Next, sixteen (16) malodor test fabrics per wash load were prepared by applying 300 μ Ι of the body soil malodor composition described in table D to a degummed 2 x 5 inch white polyester cotton cloth 50/50(PCW50/50) specimen. About 51 grams of each liquid laundry detergent to be tested (see, e.g., example 2, table 3) was added to a japanese national top-loading automatic washing machine set to normal circulation; a 68 ° f wash cycle followed by a 68 ° f rinse cycle. Cincinnati, OH, USA soft water is mixed with hard water at a known ratio to meet hardness targets-this is done automatically by the mixing station equipment and coding algorithms installed on the washing machine. The malodor test fabrics were washed in 3gpg wash water with 2.7kg, 50 x 50cm clean cotton and polyester cotton ballast and then dried in a Maytag tumble dryer set low for 20 minutes. The dried fabric was placed in a polyester film bag and sealed for 24 hours.
Subsequently, malodor reduction using ABS/squalene malodor sensor was quantified by gas chromatography mass spectrometry using Agilent gas chromatograph 7890B equipped with mass selective detector (5977B), Chemstation quantification package, and Gerstel multi-purpose sampler equipped with 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 purchased from Sigma Aldrich. The fabric was cut into uniform 2 inch by 2.5 inch pieces and placed in 10mL headspace jaw vials. Prior to analysis, vials were equilibrated for greater than 12 hours. The following settings were used in the autosampler: 80 ℃ incubation temperature, 90min incubation time, VT32-10 sample tray type, 22mm vial penetration, 20min extraction time, 54mm injection penetration and 300s desorption time. The following settings were used for the front split/no split inlet helium: split mode, 250 ℃ temperature, 12psi pressure, 79.5mL/min total flow, 3mL/min membrane purge flow, 50:1 split ratio, and 22.5min GC run time. The following settings were used in the oven: initial temperature of 40 deg.C, heating program of 12 deg.C/min, temperature of 250 deg.C and holding time of 5 min. The total nMol/L liter of 6-methyl-5-hepten-2-one (K ═ 3353), trans-2-heptenal (K ═ 3434), and 3-methyl-2-butenal (K ═ 1119) were calculated based on the partition coefficient (K at 80 ℃) of each component.
The values of these three measurements (in nmol/L) were added together to provide the total ABS/squalene marker (nmol/L) for the given test set.
Malodor reduction% oxidation products are provided as a percentage that compares the reduction in the amount of the selected malodor marker provided by the test composition compared to the (no-antioxidant) reference composition. The values were determined as follows:
reduction of oxidation product% (% marker (reference) -marker (test)) x 100/marker (reference)
The values for the marker (reference) and the marker (test) are defined as follows:
marker (reference) total ABS/squalene marker (nmol/L) of fabrics washed with a formulation without antioxidant (e.g. reference or control formulation)
Marker (test) total ABS/squalene marker (nmol/L) of fabrics washed with formulations containing the antioxidant tested
Since the measured oxidation products are generally considered malodorous, it is believed that the greater the% reduction in oxidation products provided by the composition, the less malodorous the treated fabric may have. Thus, a larger malodor reduction oxidation product% value is generally preferred. The compositions and methods of the present disclosure can provide a malodor reduction oxidation product% value 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%.
The malodor reduction may also be reported as the difference between the marker (reference) and the marker (test), showing an absolute difference (e.g. Δ ABS/squalene oxidation).
C. Perfume headspace test method
Using a mass selective detector equipped with Agilent Technologies 5977B and
J&W TM the total perfume intensity in the headspace of the fabric was determined using SPME (solid phase micro extraction) sampling technique and gas chromatography-mass spectrometry (GC-MS) with an Agilent Technologies gas chromatograph 7890B system of DB-5MS superanti-static columns (30m length x 0.25mm inner diameter x 0.25 μm film thickness). The fabric was cut into 5X 8cm and slid into a 20mL headspace vial. After three compressions with a 2kg weight, the headspace vials were conditioned on the bench for 1 hour and immediately sealed prior to analysis.
The following settings were used in the multipurpose autosampler mps (gerstel): incubation temperature of 65 ℃, incubation time of 15min, VT15-20-CVM sample tray type, 2cm gray notched SPME fiber coated with DVB/CAR/PDMS (Supelco 57299-U), vial penetration of 30mm, extraction time of 5min, injection penetration of 43mm and desorption time of 180 s. The following settings were used for the front split/no split inlet helium: no split mode, heating at 270 deg.C, 12.9psi pressure, 1.6ml/min flow. The following settings were used for the oven: initial temperature of 40 ℃ and holding time of 0.5min, heating program of 17 ℃/min, holding time of 270 ℃ and 1 min. The following settings were used for MSD: full scan mode in the range of 35 to 300 m/z.
Examples
Example 1: malodor reduction benefits of antioxidant-containing liquid laundry detergent compositions
Four (4) liquid laundry detergent compositions a-D are provided, all of which contain about 22.0 wt% surfactant comprising both NI surfactant and two AI surfactants (LAS and AES). Compositions a and C contained about 0.075 wt.% of hindered phenolic antioxidant, while compositions B and C did not contain such antioxidant. The weight ratios of NI to AI in these liquid laundry detergent compositions varied, with such ratios in compositions a and B being about 1.5, and such ratios in compositions C and D being about 0.5. The following are detailed compositional decompositions of the liquid laundry detergent compositions A-D:
TABLE 1
1 Methyl ester of 3, 5-bis (1, 1-dimethylethyl) -4-hydroxy-benzenepropanoic acid.
2 C with a weight average degree of ethoxylation of 7 12 -C 14 An alkyl ethoxylated alcohol.
3 C 11 -C 12 Linear alkylbenzene sulfonates.
4 C with a weight average degree of ethoxylation of about 3 12-14 Alkyl ethoxylated sulfates.
To show the malodor reduction effect of hindered phenol antioxidants in different surfactant systems with different NI to AI ratios, according to "test method a: sensory test for malodor reduction ", sensory tests for malodor were performed on liquid detergent compositions a-D. Composition a was used as a reference and the malodor scores for compositions B-D relative to composition a were determined by the panelists. The results of the malodor sensory test are shown in the following table.
TABLE 2
This clearly shows that the addition of hindered phenolic antioxidant can deliver improved malodor reduction at different NI to AI ratios, i.e., composition a with hindered phenolic antioxidant is superior to composition B without hindered phenolic antioxidant, and composition C with hindered phenolic antioxidant is superior to composition D without hindered phenolic antioxidant. More surprisingly, the malodor reduction effect was further improved in the high NI background (i.e., at a relatively high NI to AI weight ratio) because composition a with an NI to AI weight ratio of 1.5 was superior to composition C with an NI to AI weight ratio of 0.5, and the addition of Ralox resulted in a greater malodor reduction (i.e., 0.2 after wash and 0.7 after dry/rewet, a versus B) in the high NI background compared to the low NI background (i.e., 0 after wash and 0.2 or 0.3 after dry/rewet, C versus D).
Example 2: the comparative examples show different weight ratios of NI to AI for liquid laundry detergent compositions containing antioxidants
The effect of the malodour reducing benefit of the substance
Seven (7) liquid laundry detergent compositions E-K are provided, all of which contain about 0.075 wt% of a hindered phenolic antioxidant polymer and about 22.0 wt% of a surfactant comprising both an NI surfactant and two AI surfactants (LAS and AES). The weight ratio of NI to AI in these liquid laundry detergent compositions varies from about 0.5 to about 5, for example, about 0.5, 0.8, 1, 1.2, 1.5, 2, and 5. The following are detailed compositional decompositions of liquid laundry detergent compositions E-K:
TABLE 3
1 Methyl ester of 3, 5-bis (1, 1-dimethylethyl) -4-hydroxy-benzenepropanoic acid.
2 C with a weight average degree of ethoxylation of 7 12 -C 14 An alkyl ethoxylated alcohol.
3 C 11 -C 12 Linear alkylbenzene sulfonates.
4 C with a weight average degree of ethoxylation of about 3 12-14 Alkyl ethoxylated sulfates.
To demonstrate the malodor reduction effect of hindered phenolic antioxidants in different surfactant systems having different NI to AI ratios, the malodor reduction oxidation product values of the liquid detergent compositions E-K were tested according to test method B disclosed above (i.e., reduction relative to a control composition comprising the same ingredients but without the hindered phenolic antioxidants).

Liquid laundry detergent compositions 1-6 are made by mixing together the ingredients listed in the proportions indicated:
TABLE 4
1 Methyl ester of 3, 5-bis (1, 1-dimethylethyl) -4-hydroxy-benzenepropanoic acid.
2 Octadecyl ester of 3, 5-bis (1, 1-dimethylethyl) -4-hydroxy-benzenepropanoic acid.
3 A C12-C14 alkyl ethoxylated alcohol having a weight average degree of ethoxylation of 7.
