Description

[0001] The present invention relates to detergent compositions. Specifically, the present invention relates to liquid or solid detergent compositions for use in toilet care, manual dishwashing, automatic dishwashing, laundry, fabric care, kitchen care, carpet cleaning, air fresheners, vehicle care, polishing products, machine cleaning and maintenance, pesticides, insecticides, fungicides, herbicides, oilfield chemical applications, marine applications, personal care, and institutional / industrial cleaning. The detergent compositions are particularly suitable for household cleaning applications, such as laundry.

[0002] Detergent compositions are generally known for use in the home, particularly in laundry and dishwashing applications. Such compositions may be provided in loose powder or liquid form, wherein the user measures the amount to be used before each use.

[0003] Many consumers prefer to purchase detergent compositions in unit dose form, where the dose is pre-measured and a single tablet or sachet is placed in the washing machine or dishwasher. Unit dose detergent compositions are typically provided in the form of compressed powder tablets or sachets containing a liquid encapsulated in a water-soluble polymer.

[0004] Environmental issues related to consumer products are becoming increasingly important, with many consumers seeking alternatives that have a lower environmental impact than established products. Therefore, there is a pressing need to provide cleaning compositions that are produced from sustainable chemical raw materials and have a wide range of uses.

[0005] Cleaning compositions for household use typically contain a mixture of surfactants. Commonly used are sulfate surfactants, which produce rich foam and have excellent cleaning properties. However, sulfate-containing surfactants can be irritating to the skin, so it is desirable to minimize skin and eye irritation.

[0006] As a result, consumers are seeking cleanser compositions with more sustainable ingredients and milder, sulfate-free ingredients.

[0007] Many sulfate-free laundry detergents typically contain linear alkylbenzene sulfonate as an active ingredient. These compounds are the surfactant of choice for such applications due to their good cleaning performance at low temperatures and relatively low cost. However, linear alkylbenzene sulfonates are synthetic anionic surfactants produced from petrochemical feedstocks and are currently unavailable from renewable resources. They can also pose further environmental concerns due to their potential toxicity to aquatic life. Therefore, it is desirable to minimize the content of these surfactants in detergent compositions.

[0008] Alkoxylated surfactants, such as alcohol ethoxylates, are also commonly present in detergent compositions and provide good foaming properties.

[0009] However, some materials in their production use ethylene oxide, which can find undesirable by-products 1,4-dioxane. For health and environmental reasons, governments and regulatory bodies are working to reduce the 1,4-dioxane content in waste water and have introduced limits on the amount of 1,4-dioxane in consumer products, including household cleaners. There is therefore an increasing demand for surfactants that are free of 1,4-dioxane.

[0010] It is an object of the present invention to provide a new cleaner composition which overcomes at least one of the disadvantages of the prior art, whether described herein or otherwise.

[0011] In particular, the present invention seeks to provide a cleaner composition which maintains cleaning performance whilst minimising the content of undesirable ingredients such as sulphate, ethoxylated surfactants and linear and / or branched alkyl benzene sulphonate surfactants.

[0264] Example 1 A composition of Example 1 was prepared comprising the following components: Table 1 Composition 1 2 3 4 (comparative) 5 6 7 SLMI (wt% active) 14.50 7.25 4.83 SCMI (wt% active) 14.50 7.25 4.83 APG (wt% active) 3.50 3.50 3.50 3.50 3.50 3.50 MOT (wt% active) 7.25 4.83 7.25 4.83 COT (wt% active) 4.83 4.83 SLS (wt% active) 11.0 AE (wt% active) 7.00 Water to 100% to 100% to 100% to 100% to 100% to 100% to 100% Total surfactant 18% 18% 18% 18% 18% 18% 18%

[0265] SLMI: Sodium lauroyl methyl isethionate - commercially available solid comprising 82 wt% active SCMI: Sodium cocoyl methyl isethionate - commercially available as a solid containing 82% by weight of active material APG: Alkyl polyglucoside (decyl glucoside) - commercially available as a 50% by weight aqueous solution MOT: Methyl oleyl taurate sodium - commercially available as a solid containing 70% by weight of active material COT: Methyl cocoyl taurate sodium - commercially available as a solid containing 75% by weight of active material SLS: Sodium lauryl sulfate - commercially available as a powder or solid containing 92% by weight of active material AE: Alcohol ethoxylate (C12-15 Pareth-7) - commercially available as 100% by weight of active material Compositions 1 to 3 and compositions 5 to 7 are inventive compositions. Composition 4 is a comparative composition.

[0266] Example 2 The compositions of Example 1 were tested according to the following method, which corresponds to the standard test ASTM D4265-21 modified for use in a tergotometer: Stained and clean cotton and cotton / polyester swatches were cut into 5 cm x 5 cm squares. Compositions 1 to 7 in Example 1 were placed in different pots of a tergotometer and the temperature of each pot was adjusted to about 100 °F (37.8 °C), then the paddles of the tergotometer were lowered into each pot and the lid was put on to maintain the constant temperature. The tergotometer was set to 100 RPM with a reverse every 50 revolutions. Eight stained swatches and four clean swatches were added to each pot and washed for 30 minutes. After 30 minutes of washing, the water was drained, the swatches were squeezed to remove excess water, and then set aside. One liter of water with the same hardness as during washing was re-injected into the pots of the tergotometer and the swatches were rinsed at 100 RPM for 5 minutes. After rinsing, the water was drained, the swatches were squeezed by hand, and then laid flat to dry, avoiding direct sunlight.

[0267] Stain removal index (SRI): A colorimeter was used to measure the reflectance of the unwashed clean swatches (UF) (unwashed fabric swatches can serve as a reference for all test products).

[0268] The reflectance of the unwashed stained swatches (US) was measured before washing.

[0269] The reflectance of the washed stained swatches (WS) was measured after washing, rinsing, and drying.

[0270] CIE L*, a*, b* color values were determined from the reflectance measurements.

[0271] The SRI can be calculated using the following formula: Where: US = unwashed soiled swatch, UF = unwashed (clean) swatch, WS = washed soiled swatch.

[0272] AE*(US-UF) = Delta-E color difference between the unwashed soiled swatch and the unwashed clean swatch, and AE*(WS-UF) = Delta-E color difference between the washed soiled swatch and the unwashed (clean) swatch.

[0273] The AE* value is calculated as follows: Residual stain index (RSI): The reflectance of the unwashed clean swatch (UF) is measured (the unwashed fabric sample can serve as a reference for all test products).

[0274] After washing, rinsing, and drying, the reflectance of the washed soiled swatch (WS) is measured.

[0275] The CIE L*, a*, b* color values are determined from the reflectance measurements.

[0276] The RSI can be calculated using the following formula: Where: UF = unwashed (clean) swatch, and WS = washed soiled swatch.

[0277] The AE* value is calculated as follows: Table 2 shows the test results for compositions 1 to 4 on olive oil stains on cotton or cotton and polyester blends.

[0278] Table 2 Composition Surfactant Stain Substrate AV. Stain Release Index (SRI) * ]] AV. Residual Stain Index (RSI) * ]]> 1 SLMI + APG Olive oil Cotton 11 69 1 SLMI + APG Olive oil Polyester / cotton blend 19 71 2 SLMI + APG + MOT Olive oil Cotton 8.5 68 2 SLMI + APG + MOT Olive oil Polyester / cotton blend 20.8 71.5 3 SLMI + APG + MOT + COT Olive oil Cotton 9 68.5 3 SLMI + APG + MOT + COT Olive oil Polyester / cotton blend 21.6 71.8 4 (comparative) SLS + AE Olive oil Cotton 11 69.5 4 (comparative) SLS + AE Olive oil Polyester / cotton blend 21.5 71.5 5 SLMI + APG Olive oil Cotton 8.49 61.67 6 SLMI + APG + MOT Olive oil Cotton 8.41 61.75 7 SLMI + APG + MOT + COT Olive oil Cotton 7.74 61.57 * Each test is repeated and the average of the results is taken.

[0279] The test results show that the detergent compositions of the present application (compositions 1 to 3 and 5 to 7) provide comparable performance to prior art compositions (composition 4) comprising a sulfate salt and an ethoxylated compound.

[0280] Example 3 A formulated solid laundry composition was prepared comprising the ingredients listed in Table 3: Table 3

[0281] The composition was prepared by mixing the dry components to uniform, then slowly adding the liquid components and stirring. The sample was mixed to uniform.

[0282] Sodium sulphate, sodium bicarbonate, sodium carbonate, sodium citrate and sodium percarbonate were supplied as powders at 100% active.

[0283] SLS, SLMI, SCMI, MOT, COT and AE were as defined in Example 1.

[0284] Lauryl and decyl glucoside were commercially available as 50% by weight aqueous solutions.

[0285] Example 4 The composition prepared in Example 3 was dosed at 3.6g / L into hard water (150ppm calcium carbonate) and then tested following the procedure outlined in Example 2. The results are in Table 4: Table 4 Composition Stain Substrate SRI RSI 8 Olive oil Cotton 6.8 63.4 9 Olive oil Cotton 11.1 64.8 10 Olive oil Cotton 6.6 63.4 11 Olive oil Cotton 6.1 63.1 12 Olive oil Cotton 6.9 63.2 8 Olive oil Polyester / cotton blend 15.9 70.1 9 Olive oil Polyester / cotton blend 18.5 71.4 10 Olive oil Polyester / cotton blend 22.6 71.8 11 Olive oil Polyester / cotton blend 19.4 70.7 12 Olive oil Polyester / cotton blend 29.2 74.4

[0286] Example 5 A formulated liquid laundry composition was prepared comprising the ingredients listed in Table 5: Table 5

[0287] The composition was prepared by mixing the ingredients in the order listed in the table at room temperature, one after the other, and mixing well to ensure uniform before each addition.

[0288] SLMI, SLS and AE were as defined in Example 1.

[0289] MGDA: Methyl glycine diacetic acid - commercially available solid comprising 78% by weight active material.

[0290] CAPB: Cocamidopropyl betaine - commercially available powder comprising 78% by weight active material (compositions 13-15) or commercially available solution comprising 34% by weight active material (composition 16).

[0291] Coco glucoside: commercially available aqueous solution comprising 50% by weight active material.

[0292] The viscosity of compositions 13 to 17 was measured using a Brookfield viscometer at 25°C, spindle 21-29, 10-50 RPM and using the small sample adapter tool.

[0293] Each of Compositions 13 to 16 is a clear isotropic viscous liquid.

[0294] Example 6 The laundry wash performance of the compositions of Table 5 was evaluated on panels of different stain types using the Linitest procedure described below.

[0295] The Linitest test procedure evaluates the ability of a detergent formulation to remove applied soil on fabrics. The soiled fabric swatches are washed in a laboratory washing machine (Linitest, SDL Atlas) under specific temperature, detergent solution, wash time and water hardness conditions. The Linitest machine rotates the closed containers (8 x 500 ml) in a thermostatically controlled water bath at 40 ± 2 RPM.

[0296] The wash conditions for the wash test are shown in Table 6: Table 6 Conditions Liquid laundry detergent dose (g / L) 1 Wash time (minutes) 30 Temperature (°C) 30 Water hardness (ppm CaCO3) 300

[0297] For each run, seven swatches of the same type are placed in each closed container in the Linitest washing machine. The run is repeated four times. Each swatch is 6 cm x 6 cm in size and simulates different types of fabric and soiled stains. Table 7 lists more details of the different swatches and their product codes. The swatches are commercially available from CFT Test Material Center (Vlaardingen, The Netherlands).

[0298] Table 7 Swatch Fabric Stain A Cotton Mineral oil B Cotton Olive oil C Polyester / cotton blend Olive oil D Cotton Type A sebum E Polyester / cotton blend Type A sebum F Cotton Type B sebum G Polyester / cotton blend Type B sebum

[0299] After the wash cycle, the wash liquor is emptied and the swatches are rinsed under flowing cold tap water and then air dried on a clothesline in a fume hood (in the dark and with the fume hood air flow turned on).

[0300] The effectiveness of the test detergent on a given type of swatch (e.g. specific fabric and stain type) is evaluated by reflectance. A Datacolor 400 high performance reflectance only benchtop spectrophotometer is used. The spectrophotometer is equipped with a D65 light source and a UV cut-off filter (400 nm). The reflectance measurements are taken by the spectrophotometer as the Y value from the Y, x, y color coordinate measurements (according to the AISE protocol standard for laundry wash testing).

[0301] Measurements are taken on the soiled swatches before washing and on the cleaned swatches after washing. Measurements are taken by having each swatch in a defined set of different positions and using the average to produce the result. The results discussed herein are derived by averaging the measurements from the seven swatches (before and after washing) used in each test. The soil removal power is calculated using the following formula, which is the percent change in reflectance from the initial reflectance before the wash cycle. where: R1 = reflectance of the soiled swatch before washing R2 = reflectance of the soiled swatch after washing.

[0302] The above soil removal results are positive values, indicating that the reflectivity of the swatch material was enhanced after washing. This indicates that the cleaner composition removed or partially removed the soil from the swatch during the test.

[0303] The results of these tests are shown in Table 8.

[0304] The values in the table are the soil removal ratings for each swatch and type of soil.
