Description

Cleaning composition

[0001] The present invention relates to a cleaning composition, particularly a cleaning composition suitable for cleaning hard surface items, clothing, or the body.

[0002] Biosurfactants are surface-active substances that are mainly produced by microorganisms and have characteristic functions, and are broadly classified into glycolipid-type, fatty acid-type, peptide-type, polymer-type, etc. Among them, glycolipid-type biosurfactants have been attracting attention in many fields in recent years due to their high productivity and high functionality, and detergent compositions combining them with various surfactants have also been developed.

[0003] For example, Patent Document 1 discloses an aqueous detergent containing a glycolipid biosurfactant and a nonionic surfactant such as a fatty alcohol polyglycol ether or an anionic surfactant such as a fatty alcohol sulfate, and is intended for use in cleaning hard or soft surfaces, etc. Patent Document 2 discloses a cleaning composition containing a glycolipid biosurfactant, a sorbitan ester having a specific HLB value, and other surfactants, and attempts to use it as a hard surface cleaning composition, a ship detergent composition, etc.

[0004] (Patent Document 1) International Publication No. 2015 / 091250 (Patent Document 2) U.S. Patent Application Publication No. 2020 / 0199492

[0005] The present invention provides a detergent composition containing the following components (A) to (C): (A) a glycolipid-type biosurfactant; (B) an internal olefin sulfonate salt having from 8 to 24 carbon atoms, in which the content of an internal olefin sulfonic acid having a sulfonic acid group at the second position is 40 mass% or less; and (C) water.

[0006] In the techniques described in the above patent documents, the surfactant used in combination with the glycolipid biosurfactant may be affected by the hardness and temperature of the water used during washing, which may result in a decrease in cleaning performance. Furthermore, in order to prevent such a decrease in cleaning performance, excessive amounts of additives (e.g., builders) and solvents tend to be used, which may lead to surfactant precipitation or thickening due to the formation of a liquid crystal phase, thereby potentially impairing the stability of the composition. Furthermore, these patent documents do not address the fact that the formation of a higher-order structure or elongation of the hydrophobic chain of the glycolipid biosurfactant may increase the risk of impairing the low-temperature stability of the composition, indicating that there is still room for improvement. Furthermore, depending on the surfactant used in combination with the glycolipid biosurfactant, it may affect protein elution, which may damage not only the skin of the hands during use of the detergent composition but also natural fibers such as wool and silk that are to be washed. Furthermore, in recent years, consumer demands have increased, with demands for high quality and ease of handling, and a colorless and transparent appearance has also become more popular. However, it has been found that conventional technologies cannot adequately address these demands.

[0007] Therefore, the present invention relates to a detergent composition that uses a glycolipid biosurfactant and can exhibit excellent cleaning performance regardless of the hardness or temperature of the water used during cleaning, and that also has excellent fluidity and a good appearance.Furthermore, the present invention relates to a detergent composition that effectively suppresses protein elution, thereby effectively reducing damage not only to the skin of hands during use of the detergent composition but also to natural fibers such as wool and silk that are to be cleaned.

[0008] The present inventors have conducted extensive studies and found that by containing an internal olefin sulfonate having a specific carbon number in which the proportion of sulfonic acid groups present at the 2-position is specific, together with a glycolipid biosurfactant, a detergent composition can be obtained that is adaptable to a wide range of conditions for water used in washing and that exhibits stable and excellent cleaning performance.

[0009] The detergent composition of the present invention can stably exhibit excellent cleaning performance while avoiding the formation of unwanted precipitates when diluted during cleaning, regardless of the hardness or temperature of the water used. Furthermore, the detergent composition of the present invention also enables the use of fewer additives, such as chelating agents, and solvents, thereby realizing a highly useful detergent composition that is environmentally friendly. Furthermore, the detergent composition of the present invention has homogeneously dissolved components and moderate fluidity, allowing the detergent composition to be dispensed from a container without changing its composition even after being filled therein. Furthermore, the detergent composition of the present invention is colorless and transparent, allowing users to effectively and comfortably experience excellent cleaning performance regardless of the mode of use. Furthermore, the detergent composition of the present invention effectively suppresses protein elution, thereby effectively reducing damage to hand skin during use of the detergent composition as well as damage to natural fibers, such as wool and silk, to be cleaned. Detailed Description of the Invention

[0010] The present invention will be described in detail below. In the present invention, the "stability" of a cleaning composition or cleaning agent means that unnecessary precipitation of the components, formation of a liquid crystal phase, excessive thickening, etc. are prevented, and the components are kept uniformly dissolved (hereinafter also referred to as "uniform solubility"). In addition, in the present invention, the "colorless transparency" exhibited by a cleaning composition or cleaning agent means a state of high brightness and high transparency. Therefore, it includes not only a colorless state showing good transparency, but also a colored state that maintains brightness and transparency that does not cause problems in practical use. Therefore, "excellent colorless transparency" means that the cleaning composition or cleaning agent has an excellent appearance and a wide range of application.

[0011] The detergent composition of the present invention can be used to clean a variety of objects, but is particularly suitable as a composition for cleaning hard surface articles, clothing, or the body. That is, the detergent composition of the present invention is suitable as a detergent composition for cleaning hard surface articles, clothing, or the body (hereinafter also abbreviated as the "detergent composition" of the present invention), and can be suitably used as a detergent composition for hard surface articles, a detergent composition for clothing, or a cleansing composition for the body. The detergent composition of the present invention can also be used for the purpose of cleaning various stains. Specific examples of such stains include sebum, mud, beef tallow, foundation, lipstick, food-derived pigments such as carotene, scum, and limescale.

[0012] By hard surface article is meant an article whose surface is formed from resin, plastic, metal, glass, ceramic, wood, marble, or a combination thereof.

[0013] Clothing products refer to articles manufactured using fibers. Specific examples of such fibers include resin fibers such as protein-based fibers, polyester-based fibers, and polyvinylidene chloride-based fibers; hydrophobic fibers such as glass fibers, carbon fibers, and metal fibers (gold thread, silver thread, and steel fiber); and hydrophilic fibers such as cotton, hemp, silk fibers, wool, rush, and straw. Note that such fibers do not include hair, nor do they include fibers used in products for attaching to or decorating hair or the scalp. In other words, they do not include "fibers for head accessories" used in head accessories such as hair wigs, hairpieces, weaving, hair extensions, braided hair, hair accessories, and doll hair. Specific examples of clothing products manufactured using such fibers include fabrics such as woven fabrics, knitted fabrics, and nonwoven fabrics, as well as products manufactured using these fabrics, such as T-shirts, dress shirts, blouses, knitwear, slacks, hats, towels, handkerchiefs, socks, underwear, tights, and masks. Such clothing products do not include head accessories.

[0014] The body means the arms, legs, back, hands, neck, face, chest, and abdomen, the surfaces of which are made up of skin, but does not include the head, the surface of which is made up of scalp.

[0015] The detergent composition of the present invention contains a glycolipid biosurfactant as component (A). Biosurfactants are broadly classified into glycolipid, fatty acid, peptide, and polymer types based on the structure of their hydrophilic group. The detergent composition of the present invention contains a glycolipid biosurfactant composed of a sugar chain and a lipid. That is, the detergent composition of the present invention contains a glycolipid biosurfactant as component (A) and a specific internal olefin sulfonate salt as component (B), which will be described later, and the characteristic structures and performances of the two components exert a synergistic effect. This effectively suppresses the formation of unwanted precipitates and ensures good composition stability, regardless of the hardness or temperature of the water used during cleaning. Therefore, excellent cleaning performance can be achieved without the need for additives such as chelating agents or solvents.

[0016] Specific examples of component (A) include one or more lipids selected from the group consisting of sophorolipids, rhamnolipids, trehalose lipids, and mannosylalditol lipids. These components (A) may be protonated or may form a salt.

Alternatively, the sophorolipid may not contain LSL.

[0035] The cleaning composition of the present invention contains, in addition to the above-mentioned component (A), component (B), an internal olefin sulfonate having from 8 to 24 carbon atoms, in which the content of internal olefin sulfonate in which the sulfonic acid group is located at the 2-position is 40 mass% or less. Component (B) can be obtained by sulfonating an internal olefin. From the viewpoint of achieving both cleaning performance and stability of the cleaning composition, the number of carbon atoms in component (B) 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. The number of carbon atoms in component (B) is 8 or more, preferably 12 or more, more preferably 16 or more, and 20 or less, and even more preferably 16 or more, and 18 or less.

[0036] In the internal olefin sulfonate of component (B), the content of the internal olefin sulfonate having the sulfonic acid group at the 2-position is 40% by mass or less, 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 stability of the detergent composition, and is preferably 10% by mass or more, and even more preferably 15% by mass or more, from the viewpoint of the productivity of component (B). The content of the internal olefin sulfonate having the sulfonic acid group at the 2-position is 40% by mass or less, preferably 10% by mass or more and 35% by mass or less, more preferably 10% by mass or more and 30% by mass or less, and even more preferably 15% by mass or more and 28% by mass or less, from the viewpoint of the productivity of component (B).

[0037] From the viewpoint of achieving both cleaning performance and stability of the detergent composition, component (B) preferably contains an internal olefin sulfonate (IO-1S) having from 8 to 24 carbon atoms in which the sulfonic acid group is located at the second to fourth position, and an internal olefin sulfonate (IO-2S) having from 8 to 24 carbon atoms in which the sulfonic acid group is located at the fifth position or higher. From the above viewpoints, the mass ratio of the content of (IO-1S) to the content of (IO-2S) in component (B) ((IO-1S) / (IO-2S)) is preferably 0.50 or more, more preferably 0.60 or more, even more preferably 0.70 or more, preferably 6.5 or less, more preferably 6.0 or less, even more preferably 5.5 or less, still more preferably 5.0 or less, still more preferably 4.5 or less, still more preferably 4.0 or less, still more preferably 3.5 or less, still more preferably 3.0 or less, still more preferably 2.5 or less, still more preferably 2.0 or less, and still more preferably 1.5 or less. The mass ratio of the content of (IO-1S) to the content of (IO-2S) in component (B), ((IO-1S) / (IO-2S)), is preferably 0.50 or more and 6.5 or less, more preferably 0.60 or more and 6.0 or less, even more preferably 0.70 or more and 5.5 or less, still more preferably 0.70 or more and 5.0 or less, still more preferably 0.70 or more and 4.5 or less, still more preferably 0.70 or more and 4.0 or less, still more preferably 0.70 or more and 3.5 or less, still more preferably 0.70 or more and 3.0 or less, still more preferably 0.70 or more and 2.5 or less, still more preferably 0.70 or more and 2.0 or less, and still more preferably 0.70 or more and 1.5 or less.

[0038] The content of each compound having a sulfonic acid group at a different position in component (B) can be measured using a high-performance liquid chromatography mass spectrometer (hereinafter abbreviated as HPLC-MS). In the present invention, the content of each compound having a sulfonic acid group at a different position is determined as a mass ratio based on the HPLC-MS peak area of ​​the compound having the sulfonic acid group at each position relative to the total HAS in component (B). Here, among the compounds produced by the sulfonation of internal olefin sulfonic acid, hydroxyalkanesulfonates, i.e., hydroxy forms of internal olefin sulfonates, are referred to as HAS. Therefore, in the present invention, an internal olefin sulfonate (IO-1S) having from 8 to 24 carbon atoms and in which the sulfonic acid group is located at positions 2 to 4 refers to a sulfonate having from 8 to 24 carbon atoms and in which the sulfonic acid group is located at positions 2 to 4 in an HAS having from 8 to 24 carbon atoms. Furthermore, the internal olefin sulfonate (IO-2S) having from 8 to 24 carbon atoms and in which a sulfonic acid group is located at the 5th or higher position means a sulfonate having from 8 to 24 carbon atoms in an HAS form having from 8 to 24 carbon atoms and in which a sulfonic acid group is located at the 5th or higher position.

[0039] In addition, the maximum value of the bonding position of the sulfonic acid group in an internal olefin sulfonate (IO-2S) having from 8 to 24 carbon atoms and in which the sulfonic acid group is present at position 5 or higher varies depending on the number of carbon atoms. In addition, the mass ratio of the content of (IO-1S) to the content of (IO-2S) ((IO-1S) / (IO-2S)) is based on the finally obtained component (B). For example, even if an internal olefin sulfonate is obtained by mixing internal olefin sulfonates having a mass ratio ((IO-1S) / (IO-2S)) outside the above range, if the mass ratio ((IO-1S) / (IO-2S)) in the composition of the internal olefin sulfonate is within the above range, it is still considered to fall under the internal olefin sulfonate of component (B) in the present invention.

[0040] From the viewpoint of achieving both cleaning performance and stability of the detergent composition, the content of (IO-1S) in component (B) is preferably 90% by mass or less, more preferably 85% by mass or less, even more preferably 80% by mass or less, preferably 30% by mass or more, and more preferably 40% by mass or more. 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, and even more preferably 40% by mass or more and 80% by mass or less.

[0041] Examples of the salt of the internal olefin sulfonate salt of component (B) include alkali metal salts, alkaline earth metal (half atom) salts, ammonium salts, and organic ammonium salts. Examples of the alkali metal salts include sodium salts and potassium salts. Examples of the organic ammonium salts include alkanolammonium salts having from 1 to 6 carbon atoms.

[0042] Component (B) in the present invention can be obtained, for example, by sulfonating an internal olefin having from 8 to 24 carbon atoms, using as a raw material an internal olefin in which the mass ratio ((IO-1) / (IO-2)) of the olefin (IO-1) having from 8 to 24 carbon atoms and in which the double bond is located at the 1st to 3rd position to the olefin (IO-2) having from 8 to 24 carbon atoms and in which the double bond is located at the 5th position or higher is from 0.50 to 6.5. The internal olefins used to obtain component (B) are composed of the olefin (IO-1) having from 8 to 24 carbon atoms and in which the double bond is located at the 1st to 3rd position, the olefin (IO-2) having from 8 to 24 carbon atoms and in which the double bond is located at the 4th position, and the olefin (IO-2) having from 8 to 24 carbon atoms and in which the double bond is located at the 5th position or higher. The maximum value of the position of the double bond in the olefin (IO-2) having from 8 to 24 carbon atoms and in which the double bond is located at the 5th position or higher varies depending on the carbon number.

[0043] In the internal olefins having from 8 to 24 carbon atoms, the mass ratio ((IO-1) / (IO-2)) of the olefin (IO-1) having from 8 to 24 carbon atoms and having a double bond at position 1 to 3 to the olefin (IO-2) having from 8 to 24 carbon atoms and having a double bond at position 5 or higher is, from the viewpoint of cleaning performance, preferably 6.5 or less, more preferably 6.0 or less, even more preferably 5.5 or less, still more preferably 5.0 or less, still more preferably 4.5 or less, still more preferably 3.0 or less, still more preferably 2.5 or less, still more preferably 2.0 or less, still more preferably 1.5 or less, preferably 0.50 or more, more preferably 0.55 or more, and still more preferably 0.60 or more. In the internal olefins having from 8 to 24 carbon atoms, the mass ratio ((IO-1) / (IO-2)) of the olefin (IO-1) having from 8 to 24 carbon atoms and having a double bond present at position 1 to 3 to the olefin (IO-2) having from 8 to 24 carbon atoms and having a double bond present at position 5 or higher is preferably from 0.50 to 6.5, more preferably from 0.55 to 6.0, even more preferably from 0.60 to 5.5, still more preferably from 0.60 to 5.0, still more preferably from 0.60 to 4.5, still more preferably from 0.60 to 3.0, still more preferably from 0.60 to 2.5, still more preferably from 0.60 to 2.0, and still more preferably from 0.60 to 1.5.

[0044] The mass ratio ((IO-1) / (IO-2)) of the internal olefins for obtaining component (B) may be based on the finally obtained component (B). For example, even if an internal olefin sulfonate is obtained by further mixing an internal olefin sulfonate obtained using an olefin as a raw material whose mass ratio ((IO-1) / (IO-2)) is outside the above range, it can be considered to correspond to an internal olefin sulfonate of component (A) obtained using a specified olefin as a raw material, as long as the mass ratio ((IO-1) / (IO-2)) in the composition of the olefin corresponding to the raw material olefin is within the above range.

[0045] From the viewpoint of achieving both cleaning performance and stability of the detergent composition, the carbon number of the olefin used as a raw material for component (B) is preferably 8 or more, more preferably 12 or more, and even more preferably 16 or more. From the viewpoint of improving cleaning performance, the carbon number of the olefin used as a raw material for component (B) is preferably 24 or less, more preferably 22 or less, even more preferably 20 or less, and even more preferably 18 or less. The carbon number of the olefin used as a raw material for 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.

[0046] The internal olefins used as raw materials for component (B) also include those containing trace amounts of so-called alpha olefins (hereinafter also referred to as α-olefins), in which the double bond is located at position 1 of the carbon chain. From the viewpoints of ensuring the stability of the composition in the low temperature range, reducing production costs, and improving productivity, the content of alpha olefins in such internal olefins is preferably 10% by mass or less, more preferably 5% by mass or less, even more preferably 3% by mass or less, and preferably 0.01% by mass or more, more preferably 0.05% by mass or more.

[0047] When an internal olefin is sulfonated, β-sultone is produced quantitatively, and a portion of the β-sultone is converted to γ-sultone and olefin sulfonic acid. These are then converted to hydroxyalkanesulfonate and olefin sulfonate in the neutralization and hydrolysis step (e.g., J. Am. Oil Chem. Soc. 69, 39 (1992)). Here, the hydroxy group of the resulting hydroxyalkanesulfonate is located within the alkane chain, while the double bond of the olefin sulfonate is located within the olefin chain. The resulting product is primarily a mixture of these, and some of the product may contain trace amounts of hydroxyalkanesulfonate having a hydroxy group at the end of the carbon chain or olefin sulfonate having a double bond at the end of the carbon chain. In the present invention, these products and their mixtures are collectively referred to as internal olefin sulfonate (component (B)). Furthermore, hydroxyalkanesulfonate is referred to as a hydroxy form of internal olefinsulfonate (HAS), and olefinsulfonate is referred to as an olefin form of internal olefinsulfonate (hereinafter also referred to as IOS). The mass ratio of the compounds in component (B) can be measured by HPLC-MS. Specifically, the mass ratio can be determined from the HPLC-MS peak area of ​​component (B).

[0048] The distribution of double bonds in internal olefins can be measured, for example, by a gas chromatograph mass spectrometer (hereinafter abbreviated as GC-MS). Specifically, components differing in carbon chain length and double bond position are accurately separated using a gas chromatograph analyzer (hereinafter abbreviated as GC), and each component is subjected to a mass spectrometer (hereinafter abbreviated as MS), whereby the double bond positions can be identified and the proportions of each component can be determined from the GC peak areas. The content of the olefin having a double bond at a specific position is determined from the GC peak area. Furthermore, when olefins with different carbon numbers are mixed, the positional distribution of double bonds is expressed as the positional distribution of double bonds in olefins with the same carbon number.

[0049] In the present invention, when a mixture of multiple internal olefin sulfonates obtained from multiple types of raw material olefins having different double bond positions is used, the double bond position distribution of the olefins used as raw materials for the internal olefin sulfonate is calculated using olefins having the same number of carbon atoms. Specifically, for example, the average double bond position in a raw material olefin having 16 carbon atoms is a value calculated by the following formula (6), and the average double bond position in a raw material olefin having 18 carbon atoms is a value calculated by the following formula (7).
