Detailed Description of the Invention

[0001]

The present invention relates to a concentrated liquid detergent composition which is improved in portability, foam efficiency, detergency, mildness, fluidity and the like, which is improved in portability and distribution efficiency.

2. Description of the Related Art Conventionally, surfactants such as lyotropic liquid crystals represented by hexagonal liquid crystals and lamellar liquid crystals have been used in a specific concentration range, generally in a high concentration region, regardless of whether they are ionic or non-ionic. It is known to form a high-viscosity, high-order association structure. For example, one of the representative anionic surfactants, alkyl ethoxy sulfate salt, forms a liquid crystal that has no fluidity in a highly concentrated aqueous solution, and polyethylene, which is a typical nonionic surfactant, Glycol monoalkyl ethers also form highly viscous liquid crystals over a fairly wide concentration range in highly concentrated aqueous systems (Mitchell DJ et al., J. Chem.
Soc., Faraday Trans. 79, 975 (1983)).

[0003] This property is that the conventional surfactant concentration is 5 ~
In the case of a 25% by weight aqueous liquid detergent, there was no effect. However, in recent years, the reduction of packaging containers has led to resource savings, environmental protection, and ease of carrying and use by consumers. In addition, it is a serious problem in realizing a high concentration of a liquid detergent, which has been inevitably required due to needs of the times such as distribution efficiency. That is, when the concentration of the surfactant is increased, a highly viscous high-order association structure having extremely low fluidity is formed, so that the handling properties within the range acceptable to consumers, the dispersibility upon dilution, and the ease of use Still, it was difficult to provide foam performance. In addition, it was impossible to produce such a high-viscosity composition.

[0004] As a method of realizing a detergent composition having a high surfactant concentration, a method of adding a lower alcohol such as ethanol as a hydrotroping agent has been conventionally known, and it is actually used in many liquid detergents. However, hydrotropes composed of such lower alcohols do not have surfactant activity, so if added in an excessive amount, they may impair the original high washing performance and emulsification performance of surfactants. there were. Therefore, there has been a strong demand for the development of a method that can replace the addition of a lower alcohol-based hydrotrope.

However, the formation of such a high-viscosity association phase is a property common to almost all surfactants. Conversely, the formation of a high-viscosity association phase has a hydrophobic group and a hydrophilic group in the molecule, and the formation of micelles and the like. This is a phenomenon derived from the essence of a surfactant, which expresses many functions by forming a coalescence. For this reason, it has been extremely difficult to suppress the formation of this phase while maintaining high surface activity and cleaning performance by a conventionally known method, but development of a new technology that can solve this technical problem has been developed. Was what many researchers and engineers aspired to.

[0006] Polyalkylene glycol type nonionic surfactants are surfactants that are commonly used as detergents and emulsifiers. The polyalkylene glycol-type nonionic surfactant forms micelles that control interfacial properties such as washing in a dilute aqueous solution, but has an optically anisotropic property such as hexagonal liquid crystal and lamellar liquid crystal in a high concentration aqueous solution. It is well known to form lyotropic liquid crystals having high viscosity and poor fluidity. 40 to 70% by weight of a polyalkylene glycol type nonionic surfactant
Hexagonal liquid crystal, which is easy to form in concentrated aqueous solution of, is a kind of infinite aggregate, and a string-like aggregate in which countless surfactant molecules are associated in a cylindrical shape is densely packed in a hexagonal system when viewed in cross section. You are. Since the string-like aggregate can also be spatially entangled, the degree of freedom is very small from the viewpoint of the motility of the system. Therefore, hexagonal liquid crystals have a very high viscosity and no fluidity. on the other hand,
Polyalkylene glycol type nonionic surfactant is 7
A lamellar liquid crystal which is easy to form in a concentrated aqueous solution of 0 to 90% by weight is also a kind of infinite aggregate, in which a myriad of surfactant molecules are spread two-dimensionally in a plate shape, and the flat plate has a hydrophobic base surface. In this case, the hydrophilic base surface faces the hydrophilic base surface, and has a layered structure. The water present in the lamella liquid crystal is very small, and even if it exists, most of it is different from ordinary free water. Also, since the packing between the surfactant molecules is dense, the lamellar liquid crystal also has a very high viscosity.

For this surfactant, a method of adding a lower alcohol such as ethanol as a hydrotrope to break the liquid crystal structure in a high-concentration aqueous solution has been conventionally known. As described above, since it does not have surface activity, when added in an excessive amount, the problem of impairing the high cleaning performance and emulsification performance of the original polyalkylene glycol type nonionic surfactant and the like. there were.

The inventors of the present invention have conducted intensive studies in order to solve the above-mentioned problems.

At the time of mixing, the value of the intermolecular interaction parameter β determined by the following formula (1) is as small as -1.0 to 1.0, and the polyalkylene glycol-type nonionic surfactant is formed in a high-concentration aqueous solution. The present invention has proposed a concentrated liquid detergent composition containing at least one or more isotropic agent components having an action of optically isolating a higher-order association structure and having a water content of 50% by weight or less.

[0009] This concentrated liquid detergent composition exhibits good performance with respect to the detergency of a propylene cup to which artificial fats and oils are adhered, the foaming power by shaking a graduated glass tube, and the mild property by protein denaturation. I do. On the other hand, as a basic performance of cleaning on hard surfaces such as various tableware, glass used for cooking appliances and homes, pottery, etc., which is one practical use of such a cleaning composition, foam performance / cleaning Performance is mentioned. However, although the above-mentioned concentrated liquid detergent composition exhibits good foaming performance / washing performance, it has a foaming property in the actual usage form of foaming performance in cleaning on hard surfaces such as glass and pottery. In terms of foam durability and pottery dish / glass container cleaning performance, sufficient performance was not obtained yet.

[0010]

The present invention is widely used in various fields such as household products and chemical products which have solved the above-mentioned problems, and moreover, the reduction of packaging containers contributes to resource saving, environmental protection, and consumer protection. In response to the needs of the times such as portability, ease of use, and efficiency of distribution, we achieved a high concentration of liquid detergents and made effective use of polyalkylene glycol-type nonionic surfactants. , Especially various tableware,

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION The first feature of the present invention is that (A) the polyalkylene glycol type nonionic surfactant is 10 to 85% by weight, and (B) the isotropic agent component is 5 to 45% by weight. , And (C) 1 to 25% by weight of anionic surfactant
In a liquid detergent composition containing and as an essential component, the total surfactant content is to be 40 to 90% by weight. As described above, by setting the total surfactant content to a high concentration of 40 to 90% by weight, various types of tableware that are optically isotropic, have low viscosity, and have high fluidity, and are used at the same time, Excels in foaming and persistence when washing hard surfaces such as glass and ceramics used in cookers and dwellings, and is excellent in cleaning pottery dishes and glass containers, and also reduces distribution costs and packaging materials. Thus, a flowable, high-concentration, isotropic liquid detergent composition having a large effect on environmental preservation can be obtained. In the present invention, as described above, the total surfactant content is 40 to 90% by weight, preferably 50 to 80% by weight, and 60 to 8% by weight.
0% by weight is more preferred.

Further, the second feature of the present invention is that (A)
A polyalkylene glycol type nonionic surfactant,
It is to use the (B) isotropic agent component in combination with the (C) anionic surfactant. Thus, (C)
Mixing of ingredients makes it a fluid that has excellent foaming properties, long-lasting foamability, and cleaning properties for pottery dishes and glass containers, especially when cleaning glass, pottery, etc. used in various types of tableware, cookers, and dwellings, especially on hard surfaces. It becomes a highly concentrated isotropic liquid detergent composition.

In the present invention, the content of the component (A), which is a main component that exerts the cleaning function of the liquid detergent composition, is from 10 to 85% by weight, preferably from 20 to 60% by weight, more preferably from 20 to 60% by weight. Is 30 to 50% by weight. Also,
The content of the component (B) having the effect of isolating the component (A) is 5 to 45% by weight, preferably 10 to 40% by weight, and more preferably 15 to 35% by weight. still,
The mixing ratio of (A) the polyalkylene glycol type nonionic surfactant and (B) the isotropic agent component is 8: 2 to 2:
It is particularly preferred that the ratio be 4: 6. If the content of the component (A) or the component (B) is too low, or if the content is too close to one of the components, the effect of disturbing the orientation of the activator molecules due to mixing is insufficient, so that it is completely optically isotropic. Can not be sex,
Viscosity reduction may not be sufficient. Further, the content of the anionic surfactant as the component (C) having an effect of improving the cleaning function on the hard surface is 1 to 25% by weight, preferably 1 to 20% by weight. When the content of the component (C) is too large, it becomes insufficient to disturb the blending property of the activator molecules by mixing the components (A) and (B), and it is impossible to completely make it optically isotropic. In some cases, the decrease in viscosity may not be sufficient.

As described above, each component will be described in detail. First, the polyalkylene glycol-type nonionic surfactant component (A) of the present invention is a known surfactant that is often used as a detergent or an emulsifier as described above. Specific examples of preferred structures include polyalkylene glycol-type nonionic surfactants represented by the following general formula (2).

Embedded image R ² —O— (AO) n—R ³ (2) (In the formula, R ² is a linear or branched alkyl group or alkenyl group having 8 to 18 carbon atoms, and preferably has 2 or more carbon atoms. It is a linear or branched alkyl group having 10 to 14, and more preferably an aliphatic hydrocarbon having 9 to 12 carbon atoms.
Specific examples include an octyl group, a decyl group, a dodecyl group, a tetradecyl group and an oleyl group. R ³ is a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, and more preferably a hydrogen atom, a methyl group or an ethyl group. AO is a linear or branched oxyalkylene group having 2 to 4 carbon atoms, and an oxyethylene group and an oxypropylene group are particularly preferable. Furthermore, n represents a number of 3 to 25, and 7 to 15
Is particularly preferred. )

Specific examples of the polyalkylene glycol-type nonionic surfactant represented by the general formula (2) used in the present invention include polyethylene glycol dodecyl ether having an average degree of polymerization of oxyethylene groups of 5. Polyethylene glycol dodecyl ether having an average degree of polymerization of oxyethylene groups of 10, polyethylene glycol dodecyl ether having an average degree of polymerization of oxyethylene groups of 15, polyethylene glycol dodecyl ether having an average degree of polymerization of oxyethylene groups of 25, average of oxyethylene groups Polyethylene glycol decyl ether having a degree of polymerization of 7, polyethylene glycol tetradecyl ether having an average degree of polymerization of oxyethylene groups of 15, polyethylene glycol oleyl ether having an average degree of polymerization of oxyethylene groups of 15,

But are not limited to these.

Next, the (B) isotropic agent component used in the present invention will be described. The (B) isotropic agent component used in the present invention has a value of the intermolecular interaction parameter β obtained by the above mathematical formula (1) at the time of mixing with the polyalkylene glycol type nonionic surfactant is −1. It is a compound as small as 0.0 to 1.0, and is a compound capable of optically isotropy the higher-order association structure formed by a polyalkylene glycol-type nonionic surfactant in a high-concentration aqueous solution.

As described above, in order to collapse the lyotropic liquid crystal structure of (A) the polyalkylene glycol-type nonionic surfactant component, the polyalkylene glycol-type nonionic surfactant molecule and the isotropic agent are used. Not only that the components are well compatible, but also the interaction between the two molecules is very important. That is, if an attractive interaction between both molecules acts strongly, even if there is an effect of disturbing the orientation of the molecules by a geometric steric effect by mixing, even if there is an effect of disturbing the orientation of the molecules by the attractive intermolecular interaction. Since the packing becomes denser, the resulting liquid crystal formation is promoted, the system is not isotropic, the viscosity remains high and the handling properties are not improved. Therefore, in order for the disorder of packing and orientation due to geometric steric effects to act preferentially when mixed, an isotropic agent having a small attractive interaction between molecules is required. This intermolecular interaction is called Rose
n Proposed by MJ et al. (Rosen MJ, J. Colloid Interfac
e Sci., 86, 164 (1982)), which can be estimated by the β parameter, an interaction parameter in micelles formed in a dilute solution. That is, when two different surfactants are mixed, attractive or repulsive interactions occur between the molecules different from those when the same molecules are adjacent to each other, so that the surface adsorption phenomenon and the critical micelle concentration alone Changes occur that cannot be considered from the behavior of the system alone. This change,
When analyzed using the following equations (1) and (2), which are derived based on the Gibbs free energy equation, the interaction between two different molecules is positive for repulsive interaction,
The attractive interaction can be quantified as a negative value, and the stronger the interaction, the larger the absolute value. Therefore, in the present invention, an isotropic agent having no repulsive interaction and having a small attractive interaction is preferable as the compatibility with the polyalkylene glycol-type nonionic surfactant becomes poor, that is, β Those having a small absolute value are preferred.

The β value of the intermolecular interaction parameter with the polyalkylene glycol-type nonionic surfactant molecule determined by the above formula (1) is small, from -1.0 to 1.0.
In the case where those in the range of 0 are mixed, the polyalkylene glycol-type nonionic interface is formed by the action of geometric randomization without causing attractive interaction that promotes the structuring of the aggregate when mixed. The activator can effectively disrupt higher-order association structures such as lyotropic liquid crystals formed in highly concentrated aqueous solutions.

The (B) isotropic agent component used in the present invention is
Compounds having an alkyl group having 8 to 14 carbon atoms in the molecule are particularly preferred. In that case, the carbon number of the alkyl group is 10
The number is more preferably from 12 to 12, and specific examples include, but are not limited to, an octyl group, a decyl group, a dodecyl group, and a tetradecyl group. If the alkyl group is too short, it may not be completely compatible with the polyalkylene glycol type nonionic surfactant at the molecular level, or the surface activity may be reduced, and functions such as detergency may be impaired. On the other hand, if the length is too long, the attractive interaction between the hydrophobic groups becomes too strong when mixed with the polyalkylene glycol-type nonionic surfactant, so that it does not destroy the higher-order structure of the lyotropic liquid crystal. Rather, they often promote structuring.

As the isotropic agent component (B) used in the present invention, a compound having a sterically bulky polar group containing a nitrogen atom in the molecule is particularly preferred. Specific examples of the polar group include, but are not limited to, an amine oxide group, a carboxybetaine group, a sulfobetaine group, an amidopropylcarboxybetaine group, a trimethylammonium halide group, a pyridinium halide group, and the like. . The driving force in which a polyalkylene glycol-type nonionic surfactant forms a high-viscosity higher-order structure such as a lyotropic liquid crystal is used. Because of the orientation, the polar group of the isotropic agent component (B) is sterically bulky, so that the polyalkylene glycol type nonionic surfactant molecule which forms a lyotropic liquid crystal when mixed is used. This is preferable because the effect of disturbing the orientation is large. Further, the polyalkylene glycol group, which is a polar group of the polyalkylene glycol-type nonionic surfactant, has ether oxygen which has been anionically polarized, so that it strongly hydrates with water in an aqueous solution, and apparently as a polar group, It is known to exhibit cationic behavior (Rosen MJ, J. Colloid Interface Sci., 95, 443).
(1983)). Therefore, when mixed with a molecule having an anionic polar group, the attractive interaction between the molecules acts strongly through water, so that the polyalkylene glycol type nonionic surfactant is used in a highly concentrated aqueous solution. It promotes a higher-order structure of the lyotropic liquid crystal to be formed. Therefore,
(B) The isotropic agent component preferably has a polar group containing a cationically charged nitrogen atom in the molecule.

In the present invention, (B) the isotropic agent component comprises:
Although they can be used alone, they can be used preferably even if two or more kinds are mixed. In that case, the mixing ratio of the two (B) isotropic agent components is 2: 8 to 8:
Particularly preferred is 2. Some specific examples of preferred isotropic agent components used in the present invention are shown below, but the present invention is not limited to these.

As described above, the (A) polyalkylene glycol type nonionic surfactant and the (B) isotropic agent component, which were previously proposed by the present applicant, were mixed with 50% by weight.
The two-component concentrated liquid detergent composition containing the following water as an essential component is optically isotropic, has a low viscosity,
Although it has high fluidity, it is practically used in terms of foam performance and cleaning performance, which are important performances when cleaning various tableware, cookers, glass used in homes, pottery, etc. It was not sufficient in terms of foamability, foam persistence, and washability of pottery dishes and glass containers in the usage form. On the other hand, the concentrated liquid detergent composition of the present invention is optically isotropic by the above-mentioned (A) polyalkylene glycol type nonionic surfactant and (B) isotropic agent component, By adding (C) an anionic surfactant as an essential component without impairing the features of low viscosity and high fluidity, foaming property, foam sustainability in actual use during cleaning of hard surface,
It is a high-concentration isotropic liquid detergent composition having sufficient cleaning properties for pottery dishes and glass containers. That is, by adding (C) an anionic surfactant, a two-component system of (A) a polyalkylene glycol type nonionic surfactant and (B) an isotropic component has no texture and is short in a small amount. A foam that can only exist for a time is improved, a texture with a creamy feel, a good foaming property, and a foam lasting foam are obtained. In addition, a two-component system containing (A) a polyalkylene glycol type nonionic surfactant and (B) an isotropic component, which does not contain an anionic surfactant, can be used for cleaning pottery dishes and glass containers. Although the surface of the dish does not drain evenly, the system in which the anionic surfactant (C) is added drains water evenly, resulting in excellent cleaning of the dish surface of the pottery. This phenomenon is considered as follows. Dirt is peeled off from the ceramic dish by the action of the surfactant centering on the nonionic surfactant and the mechanical force of the sponge. A surface-active agent surrounds this dirt, and the dirt solubilized in the micelles is dispersed in water. In general, some of the dispersed material comes into contact with the ceramic dish and redeposits dirt to contaminate the ceramic dish. However, in the present invention, the addition of an anionic surfactant imparted a negative charge to the micelles surrounding the dirt. Since the surface of the ceramic dish has a negative charge, it is believed that it repels the micelles and prevents redeposition of dirt.

Next, the (C) anionic surfactant used in the present invention will be explained. Specific examples of preferable anionic surfactants used in the present invention are shown below, but the present invention is not limited thereto. Further, the following anionic surfactants can be used alone, but can also be preferably used by mixing two or more kinds.
