Description

Technical Field

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

Background Art

[0002] Biosurfactants are surfactants mainly produced by microorganisms and have characteristic functionalities. They are roughly classified into glycolipid type, fatty acid type, peptide type, and polymer type, etc. Among them, glycolipid type biosurfactants have been attracting attention in many fields in recent years because of their high utilization in terms of productivity and functionality, and the development of detergent compositions combined with various surfactants has also been carried out.

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

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the technologies described in the above patent documents, the surfactant used in combination with the glycolipid-type biosurfactant is affected by the hardness and temperature of the water used during washing, which may lead to a decrease in washing performance. In addition, in order to prevent such a decrease in washing performance, the amounts of additives (such as builders) and solvents used tend to be excessive, which may cause precipitation of the surfactant and thickening due to the formation of a liquid crystal phase, and may also be a factor that impairs the stability of the composition. Furthermore, these patent documents do not pay any attention to the fact that the higher-order structuring of the glycolipid-type biosurfactant and the lengthening of the hydrophobic chain may increase the risk of impairing the low-temperature stability of the composition, and it has been found that there is still room for improvement. Moreover, depending on the surfactant used in combination with the glycolipid-type biosurfactant, it may also affect the elution of proteins, and there is a risk of damage not only to the skin of the hands during the use of the detergent composition but also to natural fibers such as wool and silk of the object to be washed. Furthermore, in recent years, although consumers' required characteristics have increased, high quality and handleability are demanded, and it has also become preferable to exhibit a colorless and transparent appearance, it has been found that the prior art cannot sufficiently meet this requirement.

[0006] That is, the present invention relates to a detergent composition that can exhibit excellent washing performance without being affected by the hardness and temperature of the water used during washing while using a glycolipid-type biosurfactant, and that further has excellent fluidity and a good appearance. Moreover, the present invention relates to a washing composition that can effectively reduce not only the damage to the skin of the hands during the use of the detergent composition but also the damage to natural fibers such as wool and silk of the object to be washed in order to effectively suppress the elution of proteins.

Means for Solving the Problems

[0007] Therefore, the present inventors conducted various studies and found that by containing an internal olefin sulfonate having a specific number of carbon atoms and a specific ratio of sulfonic acid groups present at the 2-position together with a glycolipid-type biosurfactant, a detergent composition can be obtained that widely responds to various conditions of water used during washing and stably exhibits excellent washing performance.

[0008] Accordingly, the present invention provides the following components (A) to (C): (A) A glycolipid-type biosurfactant (B) An internal olefin sulfonate having 8 to 24 carbon atoms and a content of internal olefin sulfonic acid having a sulfonic acid group at the 2-position of 40% by mass or less (C) Water and provides a detergent composition containing the same.

Advantages of the Invention

[0009] According to the detergent composition of the present invention, when diluting during washing, it can stably exhibit excellent washing performance without being affected by the hardness and temperature of the water used and avoiding the formation of unnecessary precipitates. Further, according to the detergent composition of the present invention, it is also possible to reduce the usage amount of additives such as chelating agents and solvents, and realize a highly useful detergent composition considering the environmental load. Furthermore, in the case of the detergent composition of the present invention, since each component is in a state of being uniformly dissolved and has appropriate fluidity, when filling such a detergent composition into a container, it can be taken out from the container without changing the composition, and since it is also excellent in colorless transparency, it is possible to effectively and comfortably experience excellent washing performance without being affected by the usage mode. Moreover, in the case of the detergent composition of the present invention, since it can effectively suppress the elution of proteins, it can effectively reduce not only the damage to the skin of the hands during the use of the detergent composition but also the damage to natural fibers such as wool and silk of the washing target.

Embodiments for Carrying Out the Invention

[0010] The present invention will be described in detail below. In the present invention, the "stability" of the cleaning composition or the cleaning agent means preventing unnecessary precipitation of the contained components, formation of a liquid crystal phase, excessive thickening, etc., and maintaining a state in which each component is uniformly dissolved (hereinafter also referred to as "uniform solubility"). In the present invention, the "colorless transparency" exhibited by the cleaning composition or the cleaning agent means a state with high brightness and high transparency. Therefore, it includes not only a state that is colorless and exhibits good transparency, but also a state that is colored but maintains a brightness that causes no problems in actual use and has transparency. Therefore, "excellent colorless transparency" means presenting an excellent appearance and expanding the application range of the cleaning composition or the cleaning agent.

[0011] The cleaning composition of the present invention can be used to clean various objects, and is particularly suitable as a composition for cleaning hard surface articles, clothing products, or the body, that is, for cleaning hard surface articles, clothing products, or the body.

In addition, the cleaning composition of the present invention can also be used for the purpose of cleaning various stains. Such stains specifically include, for example, sebum, mud, beef tallow, foundation, lipstick, food-derived pigments such as carotene, scum, scale, and the like.

[0012] Hard surface articles mean articles whose surfaces are formed of resin, plastic, metal, glass, pottery, wood, marble, or a combination thereof.

Biosurfactants are roughly classified into glycolipid-type, fatty acid-type, peptide-type, polymer-type, etc. according to the structure of their hydrophilic groups. In the present invention, however, it contains a glycolipid-type biosurfactant composed of a sugar chain and a lipid. That is, in the detergent composition of the present invention, by containing the specific internal olefin sulfonate of component (B) described later together with the glycolipid-type biosurfactant of component (A), the characteristic structures and performances of each other exhibit a synergistic effect, and without being affected by the hardness and temperature of the water used during washing, the generation of unnecessary precipitates and the like can be effectively suppressed, and good stability of the composition can be ensured. Therefore, excellent washing performance can be exhibited without the need to contain additives such as chelating agents and solvents.

Such component (B) can be obtained by sulfonating an internal olefin. The carbon number of component (B) is 8 or more, preferably 12 or more, more preferably 16 or more, 24 or less, preferably 22 or less, more preferably 20 or less, and still more preferably 18 or less from the viewpoint of achieving both cleaning performance and stability of the detergent composition. And the carbon number of component (B) is 8 to 24, preferably 12 to 24, more preferably 16 to 20, and still more preferably 16 to 18.

From the above viewpoints, the mass ratio ((IO-1S) / (IO-2S)) of the content of (IO-1S) to the content of (IO-2S) in component (B) is preferably 0.50 or more, more preferably 0.60 or more, still more preferably 0.70 or more, preferably 6.5 or less, more preferably 6.0 or less, still 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, even more preferably 1.5 or less.

[0038] In addition, the content of each compound with a different position of the sulfonic acid group in component (B) can be measured by a high performance liquid chromatography mass spectrometer (hereinafter abbreviated as HPLC-MS). The content of each compound with a different position of the sulfonic acid group in the present invention is determined as the mass ratio based on the HPLC-MS peak area of the compound having the sulfonic acid group at each position in all HAS of component (B). Here, among the compounds produced by sulfonation of internal olefin sulfonic acid, the hydroxyalkane sulfonate, that is, the hydroxy form of the internal olefin sulfonate is referred to as HAS. Therefore, in the present invention, the internal olefin sulfonate (IO-1S) having 8 to 24 carbon atoms in which the sulfonic acid group is present at the 2nd to 4th positions means the sulfonate having 8 to 24 carbon atoms in the HAS form in which the sulfonic acid group is present at the 2nd to 4th positions. In addition, the internal olefin sulfonate (IO-2S) having 8 to 24 carbon atoms in which the sulfonic acid group is present at the 5th position or higher means the sulfonate having 8 to 24 carbon atoms in the HAS form in which the sulfonic acid group is present at the 5th position or higher.

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

Examples of the alkali metal salts include sodium salts and potassium salts. Examples of the organic ammonium salts include alkanolammonium salts having 1 to 6 carbon atoms.

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

[0043] In the internal olefins having 8 to 24 carbon atoms, the mass ratio ((IO-1) / (IO-2)) of the olefin having 8 to 24 carbon atoms (IO-1) in which the double bond is present at the 1st to 3rd positions and the olefin having 8 to 24 carbon atoms (IO-2) in which the double bond is present at the 5th position or higher is preferably 6.5 or less, more preferably 6.0 or less, still more 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, preferably 0.50 or more, more preferably 0.55 or more, and still more preferably 0.60 or more. And, in the internal olefins having 8 to 24 carbon atoms, the mass ratio ((IO-1) / (IO-2)) of the olefin having 8 to 24 carbon atoms (IO-1) in which the double bond is present at the 1st to 3rd positions and the olefin having 8 to 24 carbon atoms (IO-2) in which the double bond is present at the 5th position or higher is preferably 0.50 or more and 6.5 or less, more preferably 0.55 or more and 6.0 or less, still 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.

[0044] Note that the mass ratio ((IO-1) / (IO-2)) of the internal olefin for obtaining component (B) may be based on the finally obtained component (B). For example, even if it is an internal olefin sulfonate obtained by further mixing an internal olefin sulfonate obtained from an olefin having a mass ratio ((IO-1) / (IO-2)) outside the above range as a raw material, when the mass ratio ((IO-1) / (IO-2)) is within the above range in the composition of the olefin corresponding to the raw material olefin, it can be regarded as corresponding to the internal olefin sulfonate of component (A) obtained from a predetermined olefin as a raw material.

[0045] From the viewpoint of achieving both cleaning performance and the stability of the cleaning composition, the number of carbon atoms of the olefin serving as the raw material for component (B) is preferably 8 or more, more preferably 12 or more, still more preferably 16 or more. Also, from the viewpoint of improving the cleaning performance, the number of carbon atoms of the olefin serving as the raw material for component (B) is preferably 24 or less, more preferably 22 or less, still more preferably 20 or less, and even more preferably 18 or less. And the number of carbon atoms of the olefin serving as the raw material for component (B) is preferably from 8 to 24, more preferably from 12 to 22, still more preferably from 16 to 20, and even more preferably from 16 to 18.

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

[0047] When the internal olefin is sulfonated, β-sultone is quantitatively produced, and a part of the β-sultone is changed to γ-sultone and olefin sulfonic acid, and further these are converted to hydroxyalkane sulfonate and olefin sulfonate in the neutralization / hydrolysis step (for example, J. Am. Oil Chem. Soc. 69, 39(1992)). Here, the hydroxy group of the obtained hydroxyalkane sulfonate is inside the alkane chain, and the double bond of the olefin sulfonate is inside the olefin chain. Also, the obtained product is mainly a mixture of these, and in a part thereof, there may be contained in trace amounts a hydroxyalkane sulfonate having a hydroxy group at the end of the carbon chain or an olefin sulfonate having a double bond at the end of the carbon chain. In the present invention, these respective products and their mixtures are collectively referred to as internal olefin sulfonates (component (B)). Further, hydroxyalkane sulfonates are referred to as the hydroxy form (HAS) of internal olefin sulfonates, and olefin sulfonates are referred to as the olefin form of internal olefin sulfonates (hereinafter also referred to as IOS). Note that 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, each component having a different carbon chain length and double bond position is accurately separated by a gas chromatograph analyzer (hereinafter abbreviated as GC), and each is subjected to a mass spectrometer (hereinafter abbreviated as MS), whereby the double bond position can be identified, and the ratio of each can be determined from the GC peak area. The content of the olefin having a double bond at the specific position shall be determined using the value obtained from the GC peak area. Further, the position distribution of double bonds in the case of using a mixture of olefins having different carbon numbers shall be represented by the position distribution of double bonds in olefins having the same carbon number.

[0049] Note that in the present invention, when a plurality of internal olefin sulfonates obtained from a plurality of raw material olefins having different double bond positions are mixed and used, the position distribution of the double bonds of the olefins serving as the raw materials of the internal olefin sulfonates shall be calculated for olefins having the same carbon number. Specifically, for example, the average double bond position in a raw material olefin having 16 carbon atoms is a value obtained by the following formula (6), and the average double bond position in a raw material olefin having 18 carbon atoms is a value obtained by the following formula (7).
