BACKGROUND OF THE INVENTION
The present invention relates to a cleaning composition. More specifically, it is suitable for washing hair and skin, glassware such as tableware, washing of houses, washing of industrial products, etc., and has excellent detergency and sufficient consideration for environmental impact The agent composition.
[0002]
[Prior art]
Surfactant-type detergents that utilize emulsification, dispersion, solubilization, etc., which are the characteristics of surfactants, have been used mainly for hair and skin, glass such as tableware, and various detergents for residential use. .
[0003]
In addition, some dish cleaners and household cleaners use alkaline agents, and these alkaline cleaners saponify fatty acids generated by the transformation of fats and oils contained in dirt. Soap is produced and washed.
[0004]
On the other hand, an acid-type cleaning agent is used for dirt in a bathroom or the like, and decomposes and cleans fatty acid calcium which is a main component of dirt. Furthermore, a solvent-type cleaning agent using a solvent such as trichloroethylene may be used as a cleaning agent having a special purpose that requires a very high cleaning power in the cleaning of industrial products.
[0005]
Surfactant-type cleaning agents are concerned with the impact of the waste liquid on the environment when a large amount of surfactant is used, and therefore a cleaning agent having a high detergency even with a small amount of surfactant is required. .
In addition, solvent-type cleaning agents have problems of toxicity and adverse effects on the environment. Alkali-type cleaners and acid-type cleaners are dangerous to the skin and eyes, and also have problems such as corroding metals and having a great influence on the environment.
[0006]
On the other hand, Patent Document 1 describes a detergent using an isotropic surfactant continuous phase as a detergent composition having excellent cleaning performance while being of a surfactant type. However, this detergent composition is characterized by using liquid alcohol / liquid fatty acid having 4 to 8 carbon atoms, and such liquid alcohol / liquid fatty acid has a problem in odor.
[0007]
Non-Patent Document 1 describes a technique for generating a surfactant continuous phase using a fatty acid methyl ester α-sulfonic acid calcium salt as a surfactant and mono-2-ethylhexanoic acid glyceride as a cosurfactant. However, in the case of a calcium salt, foaming tends to be reduced among the performance required for the detergent. Further, when a fatty acid derived from fats and oils is included as a soil component, insoluble fatty acid calcium is generated, and the cleaning performance is remarkably lowered. Furthermore, glycerin and mono-2-ethylhexanoic acid are chemically bonded to each other by ester bonds in mono-2-ethylhexanoic acid glycerides, so the ester bonds decompose when stored for a long period of time, resulting in undesirable mono-2-ethylhexanoic acid May cause odor.

Furthermore, this invention provides the cleaning composition which contains sodium chloride or potassium chloride in the said cleaning composition further.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail.
[0020]
The amphoteric surfactant of component (A) used in the present invention has at least one cationic functional group and one anionic functional group, becomes cationic when the solution is acidic, and anionic when the solution is alkaline, and has an isoelectric point. In the vicinity, it has a property close to that of a nonionic surfactant.
Amphoteric surfactants are classified into carboxylic acid type, sulfate ester type, sulfonic acid type and phosphate ester type depending on the type of anionic group. Carboxylic acid type, sulfuric acid ester type and sulfonic acid type are preferred. Carboxylic acid types are further classified into amino acid types and betaine types. The betaine type is preferable in the present invention. Specific examples include imidazolinium betaine, alkyl betaine, and amide betaine.
[0021]
Component (B) anionic surfactant used in the present invention includes fatty acid soap, N-acyl glutamate, carboxylate type such as alkyl ether acetic acid, α-olefin sulfonate, alkane sulfonate, alkyl benzene sulfonate, etc. Sulfonic acid type, sulfate ester salt type such as higher alcohol sulfate ester salt, phosphate ester salt type and the like. Carboxylate type, sulfonic acid type and sulfate ester type are preferred, and sulfate ester type is particularly preferred. Specific examples include alkyl ethoxy sulfate salts.
[0022]
Of the sulfonate types, alkylbenzene sulfonic acids include branched-chain alkyl types and straight-chain alkyl types, which are undesirable in terms of environmental impact (biodegradability). Particularly preferred are branched alkylbenzene sulfonates.
[0023]
It is known that the amphoteric surfactant of component (A) and the anionic surfactant of component (B) have a reduced interfacial tension with oil when mixed in an aqueous solution. Interfacial tension is an important factor especially for cleaning oil, and in a solution with low interfacial tension with oil, the oil stain spontaneously becomes spherical and detaches from the base. Are known.
When only one of component (A) or component (B) is used, at 25 ° C Isotropic surfactant continuous phase Even if it is obtained, the interfacial tension is not sufficiently lowered, so that the region is narrow, and the stability may not be sufficiently satisfied in practical use.
A desirable mixing ratio of the amphoteric surfactant of component (A) to the anionic surfactant of component (B) is 9: 1 to 1: 9. When this range is deviated, the interfacial tension is not sufficiently lowered and the cleaning effect may not be sufficient.
[0024]
In the present invention, the amphoteric surfactant of component (A) and the anionic surfactant of component (B) are mixed and used. When mixed in an aqueous solution, the complex is formed by electrostatic interaction between them. And irritation to eyes and skin is greatly reduced.
[0025]
The component (C) used in the present invention is mono 2-ethylhexyl glyceryl ether or mono 2-ethyl hexanoic acid glyceride. These function as a liquid surface active aid at 25 ° C. That is, the 2-ethylhexyl group functions as a lipophilic group. Of the three —OH groups possessed by glycerin, two —OH groups other than the one —blocked by an ester bond or an ether bond of a 2-ethylhexyl group function as hydrophilic groups.
The component (C) changes the hydrophilic-lipophilic balance (HLB) of the system by forming an interface film mixed with the surfactant at a certain ratio. Specifically, the HLB of the anionic / amphoteric surfactant complex, which is a mixture of the component (A) and the component (B) that forms hydrophilic spherical micelles, rod-like micelles, etc., is slightly changed in the lipophilic direction. Therefore, the total amount of the component (A) and the component (B) and the ratio of the component (C) are very important.
When the cleaning agent according to the present invention is diluted with water, the ratio of the total amount of the component (A) and the component (B) and the component (C) is kept constant. Maintained.
[0026]
Of the component (C) of the present invention, mono 2-ethylhexyl glyceryl ether is preferable in terms of stability over time. Mono-2-ethylhexanoic acid glyceride has a lipophilic group and a hydrophilic group bonded through an ester bond, and the ester bond tends to hydrolyze over time, resulting in a slight odor derived from mono-2-ethylhexanoic acid. There is.
[0027]
The cleaning composition of the present invention contains the components (A) to (C) and the water of the component (D) at 25 ° C. Isotropic surfactant continuous phase one phase solution and It is what has become.
An isotropic surfactant continuous phase is a solution in which surfactants are infinitely associated, and means an optically isotropic transparent low-viscosity solution in which both water and oil are continuous. Middle phase microemulsion phase, bicontinuous phase, L _Three It is also called a phase, a D phase, etc., and provides an excellent cleaning effect in the present invention. By adopting the composition of the present invention, an isotropic surfactant continuous phase can be stably obtained in a wide composition range (region).
[0028]
The cleaning composition of the present invention is a mixture of the essential components (A), (B), (C) and the water of the component (D), and other components blended in the cleaning agent or cosmetic as necessary. It adds suitably in the range which does not impair the effect of this invention, and is manufactured by a conventional method according to the target dosage form. It is particularly preferable to add sodium chloride and potassium chloride. These are easy to obtain, inexpensive, and balance the hydrophilic-lipophilic balance of the anionic / amphoteric surfactant composite system, which is a hydrophilic surfactant, by the effect of salting out, that is, slightly changing in the direction of lipophilicity. As a result, the compounding amount of mono-2-ethylhexyl glyceryl ether and mono 2-ethylhexanoic acid glyceride can be reduced, which is a desirable additive.
In the present invention, the cleaning composition which is one phase of the isotropic surfactant can be specifically produced by the following steps.
The final cleaning composition to which the above essential components and other blending components have been added is placed in a screw test tube (sample), shaken vigorously, and left in a constant temperature water bath at 25 ° C. Visually confirm that the composition solution is in one phase. The “single phase state” means that the entire solution is uniform and transparent (first determin step).
Thereafter, it is confirmed that the sample has a low viscosity by gently shaking the screw test tube. When the test tube is turned upside down, if the solution does not immediately fall to the screw mouth side or gels and the solution hardly moves, there is a possibility that it is a liquid crystal phase. In particular, when it is completely gelled, it is a cubic liquid crystal phase, so it is not the one-phase region of the isotropic surfactant of the present invention (second determin step).
Further, the cleaning composition solution is held while combining two polarizing plates with a phase difference of 90 degrees, and it is confirmed that there is no light transmission. When light is transmitted, it is a lamellar liquid crystal phase or a hexagonal liquid crystal phase, and is not a one-phase region of the isotropic surfactant of the present invention (third determin step).
Finally, the electrical conductivity of the composition solution is measured. It is known that the electrical conductivity of a one-phase solution of an isotropic surfactant is about 2/3 of the value of an aqueous micelle solution produced in the same system. Further, the reverse micelle oil solution does not have electrical conductivity. When preparing an aqueous micelle solution produced in the same system, the mono-ethylhexyl glyceryl ether and mono-2-ethylhexanoic acid glyceride as component (C) are extracted without exception. Since the (A) component and the (B) component used in the present invention are ionic and highly hydrophilic, the solution composed of the water of the (A) component, the (B) component, and the (D) component is a micellar aqueous solution. That is obvious. In rare cases, crystals may precipitate, such as when the chain length of the hydrophobic group of component (A) and / or component (B) is long. In such a case, even when the component (C) is further added, one phase of the isotropic surfactant is not generated, and thus the obtained solution is not the one-phase solution of the isotropic surfactant of the present invention. .
That is, the isotropic surfactant continuous phase is an optically isotropic and transparent low-viscosity one-phase region, and if the above steps can be confirmed, the one-phase region of the isotropic surfactant continuous phase of the present invention Can be confirmed.
[0029]
Also, Isotropic surfactant continuous phase in one phase region In order to produce the resulting cleaning composition, the blending amounts of the essential components (A) to (D) can be determined simply by creating a phase diagram as shown in FIG.
FIG. 1 shows that (A) amphoteric surfactant is 2-alkyl-N-carboxymethyl-N-hydroxyethylimidazolinium betaine 5% by mass, (B) anionic surfactant is polyoxyethylene (1.5 mol) lauryl ether 5% by mass of potassium sulfate, (C) 1 to 25% by mass of mono-2-ethylhexanoic acid glyceride, (D) the temperature of the detergent composition when water is used as the residue, and mono-2-ethylhexanoic acid glyceride Is a region in which a one-phase region of an isotropic surfactant continuous phase is generated when the content of is used as a parameter.
L ₁ Is the micellar aqueous phase, L _α Represents a lamellar liquid crystal phase, D represents an isotropic surfactant continuous phase, and O represents an oil phase (excess mono 2-ethylhexanoic acid glyceride phase). The present invention provides D at 25 ° C. 1 phase region where (isotropic surfactant continuous phase) exists It is.
That is, 5% by mass of 2-alkyl-N-carboxymethyl-N-hydroxyethylimidazolinium betaine, (B) 5% by mass of polyoxyethylene (1.5 mol) potassium lauryl ether sulfate as an anionic surfactant, (C) mono The composition range in which 2-ethylhexanoic acid glyceride is 11.3 to 22.5% by mass and (D) water is the remaining amount is the present invention.
This figure is created by the following method.
1: First, the components (A), (B), (C), and (D) are weighed into a screw test tube, shaken vigorously, and then left in a constant temperature bath to observe the state of the solution. . If it is clear and completely transparent, it is one phase. If turbidity is present, leave it for a longer period of time and wait for separation of each phase. When phase separation is complete, all of the existing phases are transparent. In rare cases, when the phase separation is very slow and there is a concern about deterioration of components, a centrifugal separator is used. In this case, it is necessary to use a type capable of temperature control.
2: Next, when the solution is one phase, there is a possibility of an isotropic surfactant continuous phase, a micellar aqueous solution phase, a lamellar liquid crystal phase, and the like, and therefore, which phase is determined. The determination method uses the methods such as determination by viscosity, optical isotropy (anisotropy), and conductivity measurement described in the above paragraph “0028”.
3: When the solution is in a multiphase coexistence state, the optical isotropy (anisotropy) of each phase is confirmed after complete phase separation. One of the coexisting phases is a phase in the adjacent one-phase region. To ensure confirmation, prepare several solutions in which the composition of the solution is gradually changed toward the adjacent one-phase region. Of the multi-phase coexisting solution, the volume occupied by the total solution of the phase gradually increases. It can be confirmed from the fact that it finally increases to one phase. In addition, it is possible to check from the position of each phase in the test tube in consideration of the specific gravity. The isotropic surfactant phase of the present invention usually has a lower specific gravity than the aqueous phase and the aqueous micelle aqueous phase, and is usually lighter than the oil phase (excess mono-2-ethylhexanoic acid glyceride) and the reverse micelle oil solution phase. It is. The specific gravity of the isotropic surfactant phase and the lamellar liquid crystal phase is close, but both can be distinguished by optical isotropy.
4: According to the above procedure, a large number of solutions are prepared, phases appearing in each composition are identified, and regions are determined.
5: Next, the phase diagram is completed by changing the temperature of the thermostatic water tank and repeatedly specifying the region.
6: When the blending amounts of (A) and (B) are different from the above, a phase diagram can be prepared in exactly the same manner as in FIG. From the figure, it is possible to easily manufacture the cleaning composition of the present invention by determining the blending range of (C).
For example, when arbitrary (A) and (B) are selected, and a cleaning composition is manufactured such that (A) :( B) = 7: 3 according to the cleaning ability of the target product First, the respective blending amounts are determined so that (A) :( B) = 7: 3. Then, a phase diagram is created in the same manner as when FIG. 1 is created, and the range that (C) can take is determined. Using it as a basic formulation, add other ingredients, and at 25 ° C, Isotropic surfactant continuous phase one phase region Check.
[0030]
The isotropic surfactant continuous phase, which is a requirement of the present invention, is in a thermodynamic equilibrium state and is generated regardless of the order of addition. Therefore, any order of addition can be produced. However, in order to reach the equilibrium state most promptly, after mixing water, a surfactant, a salt and a water-soluble substance, the mono-2-ethylhexyl glyceryl ether and the mono-2-ethylhexanoic acid glyceride are gradually stirred. It is desirable to attach. In particular, when mono-2-ethylhexyl glyceryl ether or mono-2-ethylhexanoic acid glyceride is added, a lamellar liquid crystal phase having a relatively high viscosity is produced, and then an isotropic surfactant continuous phase is produced. It is desirable to add gradually using a strong stirring force.
[0031]
Whether or not the detergent composition containing the components (A) to (D) is an isotropic surfactant continuous phase is determined by (1) determination by appearance, (2) creation of a phase equilibrium diagram, (3) It can be determined by measuring electrical conductivity, (4) measuring the self-diffusion coefficient by NMR, (5) observing a replica prepared using the freeze fracture method, and the like. It may be determined by any method.
(1) In the determination by appearance, the isotropic surfactant continuous phase is a transparent low-viscosity one-phase region and is optically isotropic. The optically anisotropic liquid crystal phase can be distinguished by holding the sample while combining two polarizing plates with a phase difference of 90 degrees and confirming that there is no light transmission. The methods (2) to (5) are further effective for distinguishing between the isotropic surfactant continuous phase and the other micelle aqueous solution and reverse micelle oil solution which are other isotropic one-phase regions.
(2) In creating a phase equilibrium diagram, creating a three-component phase equilibrium diagram composed of water / oil / surfactant (surfactant includes cosurfactant surfactant) isotropic. It can be identified by having features such as a low-viscosity, low-viscosity, one-phase region, and a region that is not continuous from either water or oil, but this feature varies depending on the system (component) .
(3) In electrical conductivity measurement, it is known that the electrical conductivity of the isotropic surfactant continuous phase takes about 2/3 of the aqueous micelle phase obtained in the same system.
(4) The measurement of self-diffusion coefficient by NMR is a method described in detail by Lindman et al. In J. Colloid Interface Sci. 1981, 83, 569 and the like.
(5) According to an electron microscope observation of an isotropic surfactant continuous phase sample prepared using a freeze fracture method, an image in which both water and oil are continuous can be obtained. According to this image, water or oil can be easily distinguished from a spherical aggregate image obtained in a continuous micelle aqueous solution phase. This method is described in detail in the colloid polym. Sci. 1994, 272, 604 by Imae et al.
[0032]
Various components to be blended in the present invention are required to have good biodegradability with little influence on the environment. In the case of an alkyl group, those having a double bond have the best biodegradability, followed by linear alkyl. Among the straight-chain types, those having a short alkyl chain length are considered good. Branched alkyls are not considered biodegradable. Also, the benzene ring has a problem in biodegradability. A highly biodegradable material that has little environmental impact is desirable. The method for obtaining the degradation rate (biodegradation rate) by microorganisms is defined by the OECD Guidelines (Economic Cooperation Development Organization). Actually, TOD (Theological Oxygen Demand) obtained by theoretically calculating the amount of oxygen consumed by aerobic decomposition (BOD: Biological Oxygen Demand) from the chemical structure of the cleaning agent due to the activated mud rich in aerobic bacteria Calculated by dividing by the theoretical oxygen demand). Both the branched alkylbenzene sulfonate and the linear alkylbenzene sulfonate, which are considered to have problems in biodegradability, have a 5-day biodegradation rate of less than 5%.
The cleaning composition of the present invention is a five-day cleaning composition based on the BOD (Biological Oxygen Demand) method described in the OECD Guidelines (Chemical Substance Testing Method 301C) with due consideration for the environment. The biodegradation rate is preferably 50% or more.
