Description

Technical Field

[0001] This invention relates to a cleaning composition, and more particularly to a cleaning composition suitable for cleaning hard surface items, clothing, or the body. Background Technology

[0002] Biosurfactants are surface-active substances with unique functions, mainly produced by microorganisms, and are broadly classified into glycolipid, fatty acid, peptide, and polymeric types. Among them, glycolipid biosurfactants have received continuous attention in many fields in recent years due to their high production efficiency and functional utilization, and cleaning agent compositions combining them with various surfactants have also been developed.

[0003] For example, Patent Document 1 discloses an aqueous cleaning agent containing glycolipid-type biosurfactants, nonionic surfactants such as fatty alcohol polyethylene glycol ethers, and anionic surfactants such as fatty alcohol sulfates, intended for cleaning hard or soft surfaces. Patent Document 2 discloses a cleaning composition containing glycolipid-type biosurfactants, sorbitol esters with specific HLB values, and other surfactants, and attempts to apply it as a hard surface cleaning composition, a ship cleaning agent composition, etc.

[0004] Patent Document 1: International Publication No. 2015 / 091250

[0005] Patent Document 2: U.S. Patent Application Publication No. 2020 / 0199492 Summary of the Invention

[0006] This invention provides a cleaning agent composition containing the following components (A) to (C):

[0007] (A) Glycolipid-type biosurfactants

[0008] (B) An inner olefin sulfonate having an inner olefin sulfonic acid content of 40% by mass or less and having 8 or more carbon atoms and 24 or fewer carbon atoms at the 2-position.

[0009] (C) Water.

[0010] In the technologies described in the aforementioned patent documents, the surfactants used in combination with glycolipid-type biosurfactants are susceptible to changes in cleaning performance due to the hardness and temperature of the water used during washing. Furthermore, to prevent this reduction in cleaning performance, there is a tendency to overuse additives (such as detergent builders) and solvents, which can lead to surfactant precipitation, thickening due to the formation of a liquid crystal phase, and other factors that may compromise the stability of the composition. Moreover, these patent documents do not address the increased possibility of impaired low-temperature stability of the composition due to the higher-order structuring and elongation of hydrophobic chains in glycolipid-type biosurfactants, indicating that there is still room for improvement. Additionally, in some cases where surfactants are used in combination with glycolipid-type biosurfactants, they may adversely affect protein dissolution, potentially causing damage not only to the skin on the hands when using the cleaning agent composition but also to natural fibers such as wool and silk that are being cleaned.

[0011] In addition, in recent years, consumers' demands have become more sophisticated, requiring not only high quality and ease of use, but also a colorless and transparent appearance. However, it has been determined that existing technologies cannot adequately meet these requirements.

[0012] Therefore, the present invention relates to a cleaning agent composition that, while using glycolipid-type biosurfactants, exhibits excellent cleaning performance regardless of the hardness or temperature of the water used for cleaning, and also has excellent fluidity and presents a good appearance.

[0013] Furthermore, the present invention relates to a cleaning composition that, by effectively inhibiting the dissolution of proteins, not only effectively reduces damage to the skin of the hands when using the cleaning composition, but also effectively reduces damage to natural fibers such as wool and silk that are being cleaned.

[0014] The inventors conducted various studies and found that by containing a glycolipid-type biosurfactant and an inner olefin sulfonate with a specific amount and number of carbon atoms having a sulfonic acid group at the 2 position, a cleaning agent composition that can stably and excellently perform cleaning under various conditions of water used in cleaning can be obtained.

[0015] The cleaning agent composition according to the present invention, during the dilution process in cleaning, is unaffected by the hardness and temperature of the water used, and can stably exert excellent cleaning performance while avoiding the formation of unnecessary precipitates. Furthermore, the cleaning agent composition according to the present invention can reduce the amount of additives such as chelating agents and solvents used, and can achieve a highly useful cleaning agent composition that takes into account environmental impact.

[0016] Furthermore, in the case of the cleaning agent composition of the present invention, each component is in a uniformly dissolved state and also has moderate fluidity. Therefore, even when the cleaning agent composition is filled into a container, it can be taken out of the container without changing its composition. In addition, it has excellent colorless transparency, so it can effectively and comfortably enjoy excellent cleaning performance regardless of the method of use.

[0017] Furthermore, the cleaning agent composition of the present invention effectively inhibits the dissolution of proteins, thus not only effectively reducing damage to the skin of the hands when using the cleaning agent composition, but also effectively reducing damage to natural fibers such as wool and silk that are being cleaned. Detailed Implementation

[0018] The present invention will now be described in detail.

[0019] It should be noted that the so-called "stability" of the cleaning agent composition or cleaning agent in this invention means preventing unnecessary precipitation of the components, formation of liquid crystal phase, and excessive thickening, and maintaining a uniformly dissolved state of each component (hereinafter also referred to as "uniform solubility").

[0020] Furthermore, the so-called "colorless transparency" exhibited by the cleaning composition or cleaning agent in this invention refers to a state of high brightness and high transparency. Therefore, it encompasses not only a state of being colorless and exhibiting good transparency, but also a state of being colored yet maintaining brightness without problems in practical use and possessing transparency. Thus, the term "excellent colorless transparency" signifies exhibiting an excellent appearance, thereby expanding the applicability of the cleaning composition or cleaning agent.

[0021] The cleaning composition of the present invention can be used on a variety of objects, and is particularly suitable for use as a composition for cleaning hard surface articles, clothing articles, or the body. That is, the cleaning composition of the present invention is suitable for use as a cleaning composition for cleaning hard surface articles, clothing articles, or the body (hereinafter also simply referred to as the "cleaning composition" of the present invention), and can be suitably used as a cleaning composition for hard surface articles, a cleaning composition for clothing articles, or a cleaning composition for the body.

[0022] Furthermore, the cleaning agent composition of the present invention can also be used to clean various types of dirt. Specifically, examples of such dirt include sebum, dirt, tallow, foundation, lipstick, food-derived pigments such as carotene, soap scum, and limescale.

[0023] Hard-surfaced objects are those whose surfaces are made of resin, plastic, metal, glass, ceramics, wood, marble, or a combination thereof.

[0024] The term "clothing products" refers to items made from fibers. Specifically, these fibers include, for example, resin-based fibers such as protein fibers, polyester fibers, and polyvinylidene chloride fibers; hydrophobic fibers such as glass fibers, carbon fibers, and metal fibers (gold threads, silver threads, steel fibers); and hydrophilic fibers such as cotton, linen, silk fibers, wool, rush, and straw.

[0025] It should be noted that this fiber does not include hair, nor does it include fibers used in products for wearing or modifying hair or scalp. That is, it also does not include "fibers for headwear" used in headwear products such as wigs, hairpieces, hair extensions, hair braids, hair accessories, and doll wigs.

[0026] As for clothing products made using this fiber, examples include fabrics such as textiles, woven fabrics, and nonwoven fabrics, as well as products made from them such as T-shirts, shirts, women's shirts, knitwear, trousers, hats, towels, handkerchiefs, socks, underwear, pantyhose, and face masks.

[0027] It should be noted that this clothing product does not include headwear.

[0028] The term "body" refers to the parts of the body that are covered by skin, including the arms, legs, back, hands, neck, face, chest, and abdomen.

[0029] It should be noted that the body does not include the head, which is covered by scalp.

[0030] The cleaning agent composition of the present invention contains a glycolipid-type biosurfactant as component (A). Biosurfactants are generally classified into glycolipid-type, fatty acid-type, peptide-type, and polymer-type according to the structure of their hydrophilic groups. In the present invention, a glycolipid-type biosurfactant composed of sugar chains and lipids is contained.

[0031] That is, in the cleaning agent composition of the present invention, by containing both the glycolipid-type biosurfactant of component (A) and a specific intraolefinic sulfonate of component (B) (described later), the unique structure and properties of the two components create a synergistic effect, effectively suppressing the formation of unnecessary precipitates regardless of the hardness and temperature of the water used for cleaning, thus ensuring good composition stability. Therefore, excellent cleaning performance can be achieved without the need for additives or solvents such as chelating agents.

[0032] As component (A), specifically, one or more of the following can be selected: sophorolipids, rhamnolipids, trehalolipids, and mannose polyhydroxyol esters. These components (A) can be protonated or form salts.

[0033] Sophorolipids have a structure formed by the bonding of long-chain hydroxy fatty acids to sophorose. This structure can be either a lactone type (LSL) formed by the cyclic ester bond between the carboxyl group of the long-chain hydroxy fatty acid and the hydroxyl group of sophorose, or an acid type (ASL) formed by the hydrolysis of the lactone type.

[0034] Lactone-type sophorolipids are represented by the following formula (1), and acid-type sophorolipids are represented by the following formula (2).

[0058] The cleaning agent composition of the present invention contains, as component (A), an inner olefin sulfonate having a sulfonic acid group at position 2 in an amount of 40% by mass or less and having 8 or more and 24 carbon atoms, as component (B). This component (B) can be obtained by sulfonating the inner olefin.

[0059] Regarding the carbon number of component (B), from the viewpoint of balancing cleaning performance and the stability of the cleaning agent composition, it is 8 or more, preferably 12 or more, more preferably 16 or more, and 24 or less, preferably 22 or less, more preferably 20 or less, and even more preferably 18 or less. Furthermore, the carbon number of component (B) is 8 or more and 24 or less, preferably 12 or more and 24 or less, more preferably 16 or more and 20 or less, and even more preferably 16 or more and 18 or less.

[0060] Regarding the content of the alkylene sulfonate with a sulfonic acid group at the 2-position in component (B), from the viewpoint of the stability of the cleaning agent composition, it is preferably 40% by mass or less, more preferably 35% by mass or less, more preferably 30% by mass or less, and even more preferably 28% by mass or less. From the viewpoint of the production efficiency of component (B), it is preferably 10% by mass or more, and even more preferably 15% by mass or more.

[0061] From the viewpoint of balancing cleaning performance and the stability of the cleaning agent composition, component (B) preferably includes an inner olefin sulfonate (IO-1S) with 8 or more and 24 carbons having sulfonic acid groups at positions 2 or more and 4 or less, and an inner olefin sulfonate (IO-2S) with 8 or more and 24 carbons having sulfonic acid groups at positions 5 or more.

[0062] Regarding the mass ratio ((IO-1S) / (IO-2S)) of the content of (IO-1S) in component (B), from the above viewpoint, it is preferably 0.50 or more, more preferably 0.60 or more, even more preferably 0.70 or more, and preferably 6.5 or less, more preferably 6.0 or less, even more preferably 5.5 or less, even more preferably 5.0 or less, even more preferably 4.5 or less, even more preferably 4.0 or less, even more preferably 3.5 or less, even more preferably 3.0 or less, even more preferably 2.5 or less, even more preferably 2.0 or less, and even more preferably 1.5 or less.

[0063] It should be noted that the contents of compounds with different sulfonic acid group positions in component (B) can be determined using high-performance liquid chromatography-mass spectrometry (hereinafter referred to as HPLC-MS). The contents of compounds with different sulfonic acid group positions in this invention are determined as the mass ratio of the HPLC-MS peak areas of compounds with sulfonic acid group positions in all HAS of component (B).

[0064] Here, the hydroxyl group of the hydroxyl alkane sulfonate in the compound formed by the sulfonation of the inner alkene sulfonic acid is referred to as HAS. Therefore, in this invention, the term "inner alkene sulfonate with 8 or more carbons and 24 or fewer carbons having a sulfonic acid group at positions 2 or more and 4 or fewer" (IO-1S) refers to the sulfonate with 8 or more carbons and 24 or fewer carbons having a sulfonic acid group at positions 2 or more and 4 or fewer in the HAS form.

[0065] In addition, the term "inner olefin sulfonate (IO-2S) with sulfonic acid groups at positions 5 and above and having 8 or more but less than 24 carbons" refers to sulfonates with sulfonic acid groups at positions 5 and above and having 8 or more but less than 24 carbons in the HAS body.

[0066] It should be noted that the maximum number of positions for the sulfonic acid group in alkylene sulfonates (IO-2S) with 8 to 24 carbon atoms and a sulfonic acid group at position 5 or higher varies depending on the number of carbon atoms.

[0067] Furthermore, the mass ratio of the content of (IO-1S) to the content of (IO-2S) ((IO-1S) / (IO-2S)) is based on the final obtained component (B). For example, even if an internal olefin sulfonate is obtained by mixing internal olefin sulfonates with a mass ratio ((IO-1S) / (IO-2S)) outside the above range, it is considered to be an internal olefin sulfonate equivalent to component (B) in the present invention if the mass ratio ((IO-1S) / (IO-2S)) is within the above range in the composition of the internal olefin sulfonate.

[0068] Regarding the content of (IO-1S) in component (B), from the viewpoint of balancing cleaning performance and the stability of the cleaning agent composition, it is preferably 90% by mass or less, more preferably 85% by mass or less, even more preferably 80% by mass or less, and preferably 30% by mass or more, even more preferably 40% by mass or more. Furthermore, the content of (IO-1S) in component (B) is preferably 30% by mass or more and 90% by mass or less, more preferably 40% by mass or more and 85% by mass or less, even more preferably 40% by mass or more and 80% by mass or less.

[0069] Examples of salts of alkene sulfonates that are component (B) include alkali metal salts, alkaline earth metal (1 / 2 atom) salts, ammonium salts, or organic ammonium salts. Examples of alkali metal salts include sodium salts and potassium salts. Examples of organic ammonium salts include alkanol ammonium salts with 1 or more carbon atoms and 6 or fewer carbon atoms.

[0070] Component (B) in this invention can be obtained, for example, by sulfonating an internal olefin with 8 or more and 24 or less carbon atoms. It can be obtained by using an internal olefin (IO-1) with 8 or more and 24 or less carbon atoms whose double bond exists at position 1 or more and position 3 or less, and an internal olefin (IO-2) with 8 or more and 24 or less carbon atoms whose double bond exists at position 5 or more (IO-1 / IO-2) as a raw material with a mass ratio ((IO-1) / (IO-2)) of 0.50 or more.

[0071] It should be noted that the internal olefins used to obtain component (B) consist of olefins with 8 to 24 carbons having a double bond at positions 1 to 3 (IO-1), olefins with 8 to 24 carbons having a double bond at position 4, and olefins with 8 to 24 carbons having a double bond at position 5 or higher (IO-2). The maximum value of the double bond position in olefins with 8 to 24 carbons having a double bond at position 5 or higher (IO-2) varies depending on the number of carbons.

[0072] Regarding the mass ratio ((IO-1) / (IO-2)) of olefins with 8 or more and 24 or less carbon atoms, where the double bond exists at position 1 or more and position 3 or less (IO-1), to olefins with 8 or more and 24 or less carbon atoms, where the double bond exists at position 5 or more (IO-2), from the viewpoint of cleaning performance, it is preferably 6.5 or less, more preferably 6.0 or less, further preferably 5.5 or less, even more preferably 5.0 or less, even more preferably 4.5 or less, even more preferably 3.0 or less, even more preferably 2.5 or less, even more preferably 2.0 or less, even more preferably 1.5 or less, and preferably 0.50 or more, more preferably 0.55 or more, and even more preferably 0.60 or more. Furthermore, the mass ratio ((IO-1) / (IO-2)) of olefins with 8 or more and 24 or fewer carbon atoms, where the double bond exists at position 1 or more and position 3 or less (IO-1) to olefins with 8 or more and 24 or fewer carbon atoms, where the double bond exists at position 5 or more (IO-2) is preferably 0.50 or more and 6.5 or less, more preferably 0.55 or more and 6.0 or less, even more preferably 0.60 or more and 5.5 or less, even more preferably 0.60 or more and 5.0 or less, even more preferably 0.60 or more and 4.5 or less, even more preferably 0.60 or more and 3.0 or less, even more preferably 0.60 or more and 2.5 or less, even more preferably 0.60 or more and 2.0 or less, and even more preferably 0.60 or more and 1.5 or less.

[0073] It should be noted that the mass ratio ((IO-1) / (IO-2)) of the inner olefin used to obtain component (B) can be based on the final obtained component (B). For example, even an inner olefin sulfonate obtained by further mixing inner olefin sulfonates obtained from olefins with a mass ratio ((IO-1) / (IO-2)) outside the above range can be regarded as an inner olefin sulfonate equivalent to component (A) obtained from a given olefin as a raw material, as long as the mass ratio ((IO-1) / (IO-2)) in the olefin composition equivalent to the raw material olefin is within the above range.

[0074] Regarding the carbon number of the olefin that forms the raw material of component (B), from the viewpoint of balancing cleaning performance and the stability of the cleaning agent composition, it is preferably 8 or more, more preferably 12 or more, and even more preferably 16 or more. Furthermore, regarding the carbon number of the olefin that forms the raw material of component (B), from the viewpoint of improving cleaning performance, it is preferably 24 or less, more preferably 22 or less, even more preferably 20 or less, and even more preferably 18 or less. Moreover, the carbon number of the olefin that forms the raw material of component (B) is preferably 8 or more and 24 or less, more preferably 12 or more and 22 or less, even more preferably 16 or more and 20 or less, and even more preferably 16 or more and 18 or less.

[0075] Among the internal olefins that form component (B), trace amounts of so-called alpha-olefins (hereinafter also referred to as α-olefins) containing a double bond located at position 1 of the carbon chain are also included. Regarding the content of alpha-olefins in these internal olefins, from the viewpoint of ensuring the stability of the composition in the low-temperature range, reducing production costs, and improving production efficiency, it is preferably 10% by mass or less, more preferably 5% by mass or less, further preferably 3% by mass or less, and preferably 0.01% by mass or more, more preferably 0.05% by mass or more.

[0076] When an inner olefin is sulfonated, β-sulfonolactone is quantitatively generated. A portion of the β-sulfonolactone is converted into γ-sulfonolactone and olefin sulfonic acid. Subsequently, these substances are further converted into hydroxyalkane sulfonates and olefin sulfonates in neutralization and hydrolysis processes (e.g., J. Am. Oil Chem. Soc. 69, 39 (1992)). Here, the hydroxyl group of the resulting hydroxyalkane sulfonate is located inside the alkane chain, and the double bond of the olefin sulfonate is located inside the olefin chain. In addition, the resulting products are mainly mixtures of these, and sometimes also contain trace amounts of hydroxyalkane sulfonates with hydroxyl groups at the ends of the carbon chains, or olefin sulfonates with double bonds at the ends of the carbon chains.

[0077] In this invention, these products and mixtures thereof are collectively referred to as internal olefin sulfonates (component (B)). Furthermore, hydroxyalkane sulfonates are referred to as the hydroxyl form of internal olefin sulfonates (HAS), and olefin sulfonates are referred to as the olefin form of internal olefin sulfonates (hereinafter also referred to as IOS).

[0078] It should be noted that the mass ratio of the compounds in component (B) can be determined using HPLC-MS. Specifically, the mass ratio can be calculated based on the HPLC-MS peak area of ​​component (B).

[0079] The distribution of double bonds in alkenes can be determined, for example, using gas chromatography-mass spectrometry (GC-MS). Specifically, components with different carbon chain lengths and double bond positions are precisely separated using a gas chromatograph (GC) and introduced separately into a mass spectrometer (MS). This allows for the identification of double bond positions, and the proportions of each component can be calculated based on their GC peak areas. The content of alkenes with double bonds at specific positions is given using values ​​calculated from the GC peak areas. Furthermore, the double bond position distribution when alkenes with different carbon numbers are mixed is represented by the double bond position distribution in alkenes with the same carbon number.

[0080] It should be noted that in this invention, when multiple inner olefin sulfonates are obtained by mixing multiple raw material olefins with different double bond positions, the double bond position distribution of the raw material olefins that become inner olefin sulfonates is calculated using olefins with the same number of carbons. Specifically, for example, the average double bond position in a raw material olefin with 16 carbons is a value obtained using the following formula (6), and the average double bond position in a raw material olefin with 18 carbons is a value obtained using the following formula (7).

The separated upper phase was then recovered. 10 kg of distilled water was added to the recovered upper phase, and the mixture was stirred and dispersed. It was then heated again at 30°C while standing for 1 hour. This recovered upper phase was designated as the rapeseed oil-derived fatty acid. A culture medium containing 5% rapeseed oil-derived fatty acid, 12.5% ​​glucose, 2% yeast extract, and 0.1% urea was prepared and brought to a final volume of 15 L.

[0351] The results are shown in Table 3.

[0352] pH of the cleaning agent composition at 25°C

[0353] The pH was measured at 25°C using a pH electrode (Horiba Manufacturing Co., Ltd., model F-22).

[0354] Evaluation of the Flowability of Cleaning Agent Compositions at 25°C

[0355] Under conditions where the room temperature was adjusted to 25°C, 5 mL of the obtained cleaning agent composition was collected and contained in a glass threaded tube. The appearance was then visually inspected and evaluated according to the following criteria.

[0356] X: When the threaded tube is rotated horizontally, the cleaning agent composition flows with this action and can be easily and uniformly removed, indicating excellent flowability.

[0357] Z: The cleaning agent composition separates inside the threaded tube, or the high-viscosity phase exists unevenly and is difficult to remove evenly, indicating poor fluidity.

[0358] Evaluation of the colorless and transparent properties of cleaning agent compositions at 25°C

[0359] For cleaning agent compositions contained in glass threaded tubes, the same criteria as for evaluating flowability are applied, and their appearance is visually confirmed and evaluated according to the following standards.

[0361] B: Although it is pale yellow, it is transparent.

[0362] C: Although it is dark yellow, it is transparent and there is no problem in actual use.

[0363] D: Although it is transparent, it is brown in color, which poses a problem in actual use.

[0364] E: It is brown and opaque, and has problems in actual use.

[0365] pH of the cleaning solution at 25°C

[0366] The pH was measured at 25°C using a pH electrode (Horiba Manufacturing Co., Ltd., model F-22).

[0367] Evaluation of the cleaning performance of cleaning solutions for fabrics contaminated with artificial sebum.

[0368] 1.) Fabrication of artificial sebum-stained fabric

[0369] The artificial sebum solution (WFK 09D Synthetic sebum, BEY formulation, manufactured by wfk - Testgewebe GmbH) was uniformly dissolved at 60°C. Sudan III (manufactured by Fujifilm and Kohden Chemical Industries Co., Ltd.) was added to a concentration of 0.1 wt%, and the solution was stirred until homogeneous in a 60°C water bath. This mixture was then added dropwise in 0.1 mL increments to 6 cm square pieces of polyester / cotton blended fabric (densely woven plain weave fabric, provided by Taniguchi Shoten (4-11-15 Komatsu, Higashiyodogawa-ku, Osaka City, Osaka Prefecture)). The mixture was allowed to stand in a 55°C constant temperature bath for 3 hours to spread evenly on the white fabric. Afterward, it was allowed to stand at 25°C for 2 hours to produce the artificial sebum-stained fabric.

[0370] 2.) Evaluation of cleaning performance

[0371] The cleaning performance of the cleaning equipment was evaluated using a Terg-O-Tometer (Ueshima, MS-8212). It should be noted that this Terg-O-Tometer is a rotary cleaning device, commonly used as a model cleaning device for household fully automatic washing machines, including front-loading, top-loading, and agitator-type washing machines. It is particularly suitable for model cleaning devices equivalent to household top-loading or agitator-type fully automatic washing machines.

[0372] Four fabric pieces of artificial sebum-contaminated fabric prepared in step 1) above were cleaned using the Terg-O-Tometer at 85 rpm for 10 minutes. After cleaning, they were rinsed with tap water (20°C) for 3 minutes. The reflectance at 550 nm before and after cleaning was measured using a colorimeter (Nippon Denshoku Co., Ltd., Z-300A). The cleaning rate (%) was calculated using the following formula (x), and the average value of the four fabric pieces of artificial sebum-contaminated fabric was obtained as the evaluation index.
