Description

[Technical Field]

[0001] The present invention relates to detergent compositions. In particular, the present invention relates to liquid or solid detergent compositions for use in toilet care, hand dishwashing, automatic dishwashing, laundry, fabric care, kitchen care, carpet cleaning, air purifiers, vehicle care, abrasive products, machine cleaning and maintenance, pesticides, insecticides, fungicides, herbicides, oil field chemical applications, marine applications, personal care, and institutional / industrial cleaning. The detergent compositions may be particularly useful in household cleaning applications, such as for use in laundry. [Background technology]

[0002] Detergent compositions are commonly known for household use, particularly in laundry and dishwashing applications. Such compositions may be provided in loose powder or liquid form, with the user measuring out a dose each time before use.

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

[0004] Environmental concerns are becoming increasingly important in the context of consumer products, with many consumers striving to choose products that have a reduced environmental impact compared to established products, making it highly desirable to provide detergent compositions for a variety of uses that are produced from sustainable chemical raw materials.

[0005] Detergent compositions for home use typically contain a mixture of surfactants. Sulfate surfactants are commonly used because they have high foaming and excellent detergent properties. However, sulfate-containing surfactants can be harsh on the skin, and it is desirable to minimize skin and eye irritation as much as possible.

[0006] As a result, consumers are seeking detergent compositions that contain more sustainable ingredients and gentler sulfate-free blend ingredients.

[0007] Many sulfate-free laundry detergents generally contain linear alkylbenzene sulfonate active ingredients. These compounds are surfactants that have been favored for such applications due to their good cleaning performance at low temperatures and relatively low costs. However, linear alkylbenzene sulfonates are synthetic anionic surfactants produced from petrochemical raw materials and cannot currently be obtained from renewable sources. They also present additional environmental concerns due to potential toxicity to aquatic organisms. Therefore, it is desirable to minimize the level of such surfactants present in detergent compositions.

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

[0009] However, the undesirable by-product 1,4-dioxane is found in some materials that use ethylene oxide in production.Due to health and environmental concerns, governments and regulatory agencies are working to reduce the level of 1,4-dioxane in wastewater, and have introduced restrictions on the amount of 1,4-dioxane that can be tolerated in consumer products, including household cleaners.Therefore, the demand for 1,4-dioxane-free surfactants is increasing. Summary of the Invention [Problem to be solved by the invention]

[0010] It is a goal of the present invention to provide novel detergent compositions that overcome at least one disadvantage of the prior art, whether described herein or otherwise.

[0011] In particular, the present invention seeks to provide detergent compositions that maintain cleaning performance while minimizing levels of undesirable admixture components such as sulfates, ethoxylated surfactants, and linear and / or branched alkyl benzene sulfonate surfactants.

[0264] The invention will now be further described with reference to the following non-limiting examples. [Example]

[0265] A composition of Example 1 was prepared containing the following ingredients: [Table 1] SLMI: Sodium lauroyl methyl isethionate - commercially available as a solid containing 82 wt% active material SCMI: Sodium cocoyl methyl isethionate - commercially available as a solid containing 82 wt% active substance APG: Alkyl polyglucoside (decyl glucoside) - commercially available as a 50 wt% aqueous solution MOT: Sodium methyl oleoyl taurate - commercially available as a solid containing 70 wt% active substance COT: Sodium methyl cocoyl taurate - commercially available as a solid containing 75 wt% of the active substance SLS: Sodium lauryl sulfate - commercially available as a powder containing 92% active substance by weight AE: Alcohol ethoxylate (C12-15 Pareth-7) - commercially available as 100 wt% active material Compositions 1 to 3 and 5 to 7 are according to the invention, and composition 4 is a comparative example. [Example]

[0266] The composition of Example 1 was tested according to the following method, which corresponds to standard test ASTM D4265-21, modified for use in a tergotometer. Soiled and clean cotton and cotton / polyester swatches were cut into 5 cm x 5 cm squares. Compositions 1-7 from Example 1 were placed in separate tergotometer pots. After adjusting the temperature of each pot to approximately 100°F (37.8°C), a tergotometer paddle was lowered into each pot and covered to maintain temperature. The tergotometer was set to 100 RPM and inverted every 50 revolutions. Eight soiled swatches and four clean swatches were added to each pot and washed for 30 minutes. After the 30-minute wash was completed, the water was drained, and the swatches were squeezed to remove excess water and set aside. The tergotometer pots were refilled with 1 liter of water of the same hardness as used during the wash, and the swatches were rinsed by running the swatch at 100 RPM for 5 minutes. After rinsing, the water was drained, and the swatches were wrung out by hand and laid flat, away from direct sunlight, to air dry.

[0267] Stain Removal Index (SRI): A colorimeter was used to measure the reflectance of an unwashed, clean swatch (UF) (the unwashed fabric sample can be used as a reference for all products tested).

[0268] Prior to washing, the reflectance of an unwashed soiled swatch (US) was measured.

[0269] After washing, rinsing and drying, the reflectance of the washed soiled swatches (WS) was measured.

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

[0271] SRI is calculated using the following equation:

[0273] Residual Stain Index (RSI): The reflectance of an unwashed clean swatch (UF) was measured (the unwashed fabric sample can be used as a reference for all products tested).

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

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

[0276] RSI is calculated using the equation:

[0277] Value Delta E * teeth,

number

[0278] The results of testing compositions 1-4 for olive oil staining on cotton or cotton-polyester blends are shown in Table 2. [Table 2]

[0279] The test results show that the detergent compositions of the present invention (Compositions 1-3 and 5-7) provide performance that closely approximates that of a prior art composition containing a sulfate and an ethoxylated compound (Composition 4). [Example]

[0280] Formulated solid laundry compositions were prepared containing the mixture ingredients listed in Table 3. [Table 3]

[0281] The compositions were prepared by blending the dry ingredients until uniform, then slowly adding the liquid ingredients while mixing. The samples were blended until uniform.

[0282] Sodium sulfate, sodium bicarbonate, sodium carbonate, sodium citrate, and sodium percarbonate were provided as 100% active ingredients in powder form.

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

[0284] Lauryl glucoside and decyl glucoside are commercially available as 50 wt % aqueous solutions. [Example]

[0285] The composition prepared in Example 3 was dissolved in hard water (150 ppm calcium carbonate) at a dosage of 3.6 g / L and then tested according to the procedure described in Example 2. The results are in Table 4. [Table 4] [Example]

[0286] Formulated liquid laundry compositions containing the mixture ingredients listed in Table 5 were prepared. [Table 5]

[0287] The compositions were prepared at room temperature by combining the mixture ingredients sequentially in the order listed in the table, with thorough mixing to ensure homogenization before each addition.

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

[0289] MGDA: Methylglycine diacetic acid - commercially available as a solid containing 78 wt% active. CAPB: Cocoamidopropyl betaine - commercially available as a powder containing 78 wt% actives (Compositions 13-15) or as a solution containing 34 wt% actives (Composition 16). Cocoglucoside: Commercially available as an aqueous solution containing 50 wt% active ingredient.

[0290] The viscosities of compositions 13-17 were measured using a Brookfield Viscosimeter at 25°C, spindles 21-29, 10-50 RPM, using a small sample adapter fixture.

[0291] Each of Compositions 13 to 16 is a transparent, isotropic viscous liquid. [Example]

[0292] The laundry cleaning performance of the compositions in Table 5 was evaluated on panels of various soil types using the Linitest procedure described below.

[0293] The Linitest procedure evaluates the ability of detergent formulations to remove applied soil from fabrics. Swatches of soiled fabric are washed in a laboratory washing machine (Linitest, SDL Atlas) under specified conditions of temperature, detergent solution, wash time, and water hardness. The Linitest machine rotates closed canisters (8 x 500 mL) in a thermostatically controlled water bath at 40 ± 2 RPM.

[0294] The washing conditions for the washing test were as shown in Table 6. [Table 6]

[0295] For each run, seven swatches of the same type were placed in each closed canister in the Linitest washing machine. The run was repeated four times. The swatches were each 6 cm x 6 cm in size and represented different types of fabrics and dirty soiling. Further details about the type of soiling of the different swatches and their product codes are given in Table 7. The swatches are commercially available from CFT Center for Test Material (Vlaardingen, The Netherlands). [Table 7]

[0296] After the wash cycle, the wash waste was emptied and the rags were rinsed under running cold tap water and then dried on a clothesline in a fume hood (in the dark, with the fume hood airflow switched on).

[0297] The effectiveness of test detergents on a given type of swatch (e.g., a specific fabric and stain type) was evaluated by reflectance measurements. A Datacolor 400 high-performance, reflectance-only benchtop spectrophotometer was used. The spectrophotometer had a D65 light source and a UV-cut filter (400 nm). Reflectance measurements were taken by the spectrophotometer using the Y value of the Y, x, y color coordinate measurement (in accordance with the AISE protocol standard for laundry wash testing).

[0298] Measurements were taken of the soiled swatches before washing and of the cleaned swatches after washing. Measurements were taken of each swatch at a defined set of various locations and the average value was used to generate the results. The measurements (before and after washing) for the seven swatches used in each test were averaged to generate the results discussed herein. Detergency was calculated as the percentage change in reflectance compared to the initial reflectance before the wash cycle using the following formula:

number

[0299] For the detergency calculation above, a positive value means that the swatch material became more reflective after washing, indicating that the detergent composition removed or partially removed the stain from the swatch during the test.

[0300] The results of these tests are provided in Table 8.

[0301] The values ​​in the table are the detergency scores for each swatch and stain type. Table 8
