Detailed Description

< detergent composition for fiber products >

The present inventors have found that the soil release effect by a detergent can be further improved by using, together with a detergent, an internal olefin sulfonate having 16 to 24 carbon atoms and having 16 to 24 carbon atoms in which the sulfonic acid group is present at the 2-4 position and the lower carbon atom is present at the 2-5 position, and an internal olefin sulfonate (IO-1S) having 16 to 24 carbon atoms in which the sulfonic acid group is present at the 5-5 position, the mass ratio of (IO-2S)/(IO-1S) being 0.30 to 5. It has not been known in the prior art that detergent compositions for fiber products containing an internal olefin sulfonate and a detergent differ in cleaning performance depending on the bonding position of the sulfonic acid group of the internal olefin sulfonate.

< ingredient (A) >

The component (A) of the present invention is an internal olefin sulfonate having 16 to 24 carbon atoms, wherein the mass ratio of an internal olefin sulfonate (IO-1S) having 16 to 24 carbon atoms in which a sulfonic acid group is present at 2 to 4 positions and the mass ratio of an internal olefin sulfonate (IO-2S) having 16 to 24 carbon atoms in which a sulfonic acid group is present at 5 positions is 0.30 to 5 inclusive in terms of (IO-2S)/(IO-1S), and the component (A) further improves the effect of releasing dirt attached to fibers from a textile product by a detergent.

In general, anionic surfactants sometimes have the following: it is also adsorbed on the fiber product in the cleaning liquid, and its adsorption ratio to the dirt attached to the fiber product is reduced. The inventors speculate that: in the component (a) of the present invention, the content ratio of the internal olefin sulfonate (IO-2S) having 16 or more and 24 or less carbon atoms in which the sulfonic acid group is present at the 5-position is increased, and the component (a) selectively adsorbs dirt adhering to a fiber product (particularly, a fiber product containing chemical fibers), thereby modifying the dirt into a state in which the dirt is easily released into a cleaning liquid, and further improving the detergency of the component (B).

The component (a) is an internal olefin sulfonate having 16 or more and 24 or less carbon atoms, which means an olefin having a double bond existing at a position more inside than the 2-position, and is obtained by isomerizing a 1-olefin obtained by dehydrating a 1-alcohol, for example, if the internal olefin is sulfonated, β -sultone is quantitatively produced, β -sultone is partially converted into γ -sultone and olefin sulfonic acid, which are further converted into hydroxyalkane sulfonate and olefin sulfonate in a neutralization and hydrolysis step (for example, j.am. oil chem.soc.69,39(1992)), where the hydroxyl group of the obtained hydroxyalkane sulfonate is located inside the alkane, and the double bond of the olefin sulfonate is located inside the olefin sulfonate, and the obtained product is mainly a mixture thereof, and further, a small amount of a component having a hydroxyl group at the terminal thereof is contained in a carbon chain of the obtained hydroxyalkane sulfonate, and a mixture thereof is also referred to as olefin sulfonate (hereinafter, also referred to as olefin sulfonate having a double bond at the terminal of the hydroxyl group in this specification).

The component (A) contains an internal olefin sulfonate (IO-1S) having 16 to 24 carbon atoms and having a sulfonic acid group at the 2-to 4-position and an internal olefin sulfonate (IO-2S) having 16 to 24 carbon atoms and having a sulfonic acid group at the 5-position, and the mass ratio of (IO-2S)/(IO-1S) is 0.30 to 5.

From the viewpoint of further improving the detergency of the component (B) by selectively adsorbing the dirt to modify the dirt into a state in which the dirt is easily released into the cleaning liquid, thereby further improving the detergency to the dirt adhering to the fiber product containing the chemical fiber, the mass ratio of the content of (IO-2S) to the content of (IO-1S) in the component (a), i.e., (IO-2S)/(IO-1S), is 0.30 or more, preferably 0.35 or more, more preferably 0.40 or more, further preferably 0.50 or more, further more preferably 0.60 or more, further more preferably 0.70 or more, further more preferably 0.80 or more, further more preferably 0.90 or more, further more preferably 1.0 or more, and 5 or less, preferably 4 or less, and more preferably 3 or less.

The content of each compound having a different sulfonic acid group position in the component (A) can be measured by a high performance liquid chromatography-mass spectrometer (hereinafter abbreviated as HP L C-MS). The content of each compound having a different sulfonic acid group position in the present specification is determined based on the mass ratio of the peak area of HP L C-MS of the compound having a sulfonic acid group at each position in the entire HAS form of the component (A). Here, HAS is a hydroxyalkanesulfonate, that is, a hydroxymer of an internal olefin sulfonate, in the compound produced by sulfonation of an internal olefin sulfonic acid.

In the present invention, the content of the internal olefin sulfonate (IO-1S) having 16 to 24 carbon atoms with the sulfonic acid group being present at the 2-or 4-or lower position is a value representing the peak area of HP L C-MS based on the sulfonate having 16 to 24 carbon atoms with the sulfonic acid group being present at the 2-or 4-or lower position in the HAS compound having 16 to 24 carbon atoms.

The content of the internal olefin sulfonate (IO-2S) having 16 to 24 carbon atoms and having the sulfonic acid group at the 5-position is represented by a value obtained by measuring the peak area of HP L C-MS based on the sulfonate having 16 to 24 carbon atoms and having 5 to 5 carbon atoms in the HAS monomer having 16 to 24 carbon atoms.

The internal olefin sulfonate as component (A) includes an internal olefin sulfonate (IO-1S) having 16 to 24 carbon atoms with the sulfonic acid group being present at the 2-4 position and an internal olefin sulfonate (IO-2S) having 16 to 24 carbon atoms with the sulfonic acid group being present at the 5-5 position. The maximum value of the position of bonding of sulfonic acid groups in the internal olefin sulfonate (IO-2S) differs depending on the number of carbon atoms.

The mass ratio of component (A), (IO-2S)/(IO-1S), was set based on the finally obtained component (A). For example, even if an internal olefin sulfonate obtained by mixing an internal olefin sulfonate having a mass ratio (IO-2S)/(IO-1S) deviating from the above range is used, the internal olefin sulfonate corresponding to the component (A) is considered to be present as long as the mass ratio (IO-2S)/(IO-1S) in the composition of the internal olefin sulfonate is within the above range.

(A) The internal olefin sulfonate of component (b) has 16 or more carbon atoms and 24 or less, preferably 22 or less, more preferably 20 or less, and still more preferably 18 or less. (A) The component (B) is preferably an internal olefin sulfonate having 16 carbon atoms. That is, the detergent composition for textile products of the present invention preferably contains an internal olefin sulfonate having 16 carbon atoms as the component (a). The number of carbon atoms of the salt moiety is not included in the number of carbon atoms of the component (A). That is, the number of carbon atoms in the olefin moiety is the number of carbon atoms in the component (A).

As the salt of the internal olefin sulfonate, an alkali metal salt, an alkaline earth metal (1/2 atom) salt, an ammonium salt or an organic ammonium salt may be mentioned. Examples of the alkali metal salt include sodium salt and potassium salt. Examples of the organic ammonium salt include an alkanolammonium salt having 1 to 6 carbon atoms.

(A) The content of the α -olefin sulfonate in the internal olefin sulfonate is limited from the viewpoint of further improving the cleaning property of the dirt adhering to the textile product including the chemical fiber, and the upper limit of the content is 10 mass% or less, more preferably 7 mass% or less, further preferably 5 mass% or less, further more preferably 3 mass% or less, and preferably 0.01 mass% or more from the viewpoint of reducing the production cost and improving the productivity.

The component (a) of the present invention can be obtained by sulfonating an olefin having 16 to 24 carbon atoms in which a double bond is present at the 2-position or more as a main component, and if the internal olefin is sulfonated, β -sultone is quantitatively produced, part of β -sultone is converted into γ -sultone and alkene sulfonic acid, and further, they are converted into hydroxyalkane sulfonate and alkene sulfonate in the neutralization and hydrolysis steps (for example, j.am.oil chem.soc.69,39 (1992)).

In the present specification, these respective products and their mixtures are collectively referred to as internal olefin sulfonates ((a) component). The hydroxyalkane sulfonate is referred to as internal olefin sulfonate hydroxo group (HAS), and the olefin sulfonate is referred to as internal olefin sulfonate olefin body (hereinafter, also referred to as IOS).

The mass ratio of the compound in component (A) can be measured by high HP L C-MS, and specifically, the mass ratio can be determined from the peak area of HP L C-MS of component (A).

In addition, the meaning of "1 or more groups selected from a cationic group and a hydrocarbon group having 1 or more and 18 or less carbon atoms are bonded to a group obtained by removing a hydrogen atom from a hydroxyl group of a polysaccharide or a derivative thereof directly or via a linking group" does not include the following forms: that is, a cationic group (for example, a nitrogen cation) is directly and covalently bonded to a group (that is, an oxygen atom) obtained by removing a hydrogen atom from a hydroxyl group of a polysaccharide or a derivative thereof.

Examples of the polysaccharide include 1 or more polysaccharides selected from cellulose, guar gum, and starch. (b1) The component (c) is a polysaccharide derivative, and a polysaccharide derivative can be used as a precursor compound for obtaining the polysaccharide derivative.

The polysaccharide derivative as the precursor compound of the component (b1) includes a polysaccharide derivative in which a part or all of the hydrogen atoms of the hydroxyl groups of the polysaccharide are substituted with a hydroxyalkyl group having 1 to 4 carbon atoms (hereinafter, also referred to as a "hydroxyalkyl substituent").

If the degree of substitution of the cationic group of the polysaccharide derivative having a cationic group in the component (b1) is high, the component (a) having an anionic group interacts with the component (b1) having a cationic group in a large amount during cleaning, so that the hydrophobicity of the component (a) and the component (b1) having a cationic group becomes high, and the hydrophobicity becomes higher than that of water contained in the cleaning liquid, and the release from the fiber product becomes difficult. On the other hand, from the viewpoint that the fiber product is easily negatively charged in the cleaning liquid, interacts with the component (b1) having a cationic group, and is easily adsorbed to the fiber product, the cationic group-containing component (b1) preferably has a high substitution degree of the cationic group. Further, the inventors consider that: the soil release agent of component (b1) containing a cationic group attached to the fiber product has a smaller number of moles of the cationic group than the anionic group of component (a), and thus the soil release agent is easily detached from the fiber product together with dirt during cleaning by interaction with the anionic group. In view of these points, in the present invention, it is preferable to select a value of the degree of substitution of the cationic group. From the above-described viewpoint, the substitution degree of the cationic group of the polysaccharide derivative having a cationic group as the component (b1) is preferably 0.001 or more, more preferably 0.005 or more, further preferably 0.01 or more, and preferably 1 or less, more preferably 0.7 or less, further preferably 0.4 or less, further more preferably 0.35 or less, further more preferably 0.3 or less, further more preferably 0.25 or less, and further more preferably 0.2 or less.

For example, when the polysaccharide is cellulose, the "degree of substitution with a group" represents the average number of moles of the group introduced per 1 mole of anhydroglucose unit. The degree of substitution of the cationic group and the degree of substitution of the hydrocarbon group having 1 to 18 carbon atoms in the polysaccharide derivative were determined by the methods described in examples.
