DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a reduction in the number of packaging containers,
The present invention relates to a concentrated liquid detergent composition having improved foamability, detergency, mildness, etc., which is improved in portability, distribution efficiency, and the like, and in particular, has improved finish on hard surfaces.

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. As a result, the concentrated liquid containing the following two components (A) and (B) as essential components first. A cleaning composition, that is, a polyalkylene glycol type nonionic surfactant which is the component (A) of the present invention, and a polyalkylene glycol type nonionic surfactant which is the component (B) of the present invention. 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.

Mixed in Indicates the critical micelle concentration of the combined system. ｝ The larger the value of β, the greater the repulsive interaction, and the larger the value of β, the greater the attractive interaction.

[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, in the cleaning of hard surfaces such as various dishes, cookware and home-use glass and ceramics which are one practical use of such a detergent composition, in recent years, the conventional foam performance It has been pointed out that, in addition to the cleaning performance and the mildness performance, the finish of the hard surface is also required. That is, for example, when the pottery dish with oil is washed with a sponge impregnated with detergent, rinsed and then dried as it is, the hydrophobic detergent or oil remaining on the hard surface, and the adhesion of the metal salt thereof, etc. In some cases, water is repelled and the surface finish is impaired. Similarly, in the case of washing glass, if a hydrophobic substance adheres, the rinsing treatment alone does not make the preparation easy, and the transparency of the glass may be impaired. This concentrated liquid detergent was not sufficiently satisfactory with respect to the finish of the hard surface.

[0010]

The present invention has been widely used in a wide variety of fields such as household goods and chemicals which have solved the above-mentioned problems. In addition, the present invention saves resources by reducing the number of packaging containers, protects the environment and protects consumers. In response to the needs of the times, such as ease of carrying, ease of use, and more efficient distribution, we realized a high concentration of liquid detergents and made effective use of polyalkylene glycol-type nonionic surfactants. In particular, it improves the finish of hard surfaces such as glass and ceramics, and furthermore, detergency,
An object of the present invention is to provide a high-concentration liquid detergent composition which is excellent in detergent performance such as mildness and fluidity.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The first feature of the present invention is that (A) 10 to 85% by weight of a polyalkylene glycol type nonionic surfactant and (B) 5 to 45% by weight of an isotropic agent component. And (C) a liquid detergent composition containing 0.001 to 5% by weight (solid content) of a specific plant extract as an essential component, to have a total surfactant content of 40 to 90% by weight. . By containing the components (A) and (B) and making the total surfactant content as high as 40 to 90% by weight, the composition is optically isotropic, has a low viscosity, and has good fluidity. Is high, and at the same time various kinds of tableware,
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 more preferably 60 to 80% by weight.
% By weight is more preferred.

Further, the second feature of the present invention is that (A)
It is to use a polyalkylene glycol-type nonionic surfactant, the (B) isotropic agent component, and the (C) extract obtained from a specific plant material in combination. By blending the component (C) in this manner, the finish of cleaning hard surfaces such as glass and ceramics can be improved.

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 10 to 85% by weight, preferably 20 to 60% by weight, more preferably 30% by weight. ５０50% by weight.

0% by weight, more preferably 15 to 35% by weight.
The mixing ratio of (A) the polyalkylene glycol type nonionic surfactant to (B) the isotropic agent component is 8: 2.
４4: 6 is particularly preferred. 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. Furthermore, the content of the plant extract of the component (C), which has an effect of improving the finish of cleaning hard surfaces such as glass porcelain, is 0.1%.
It is 001 to 5% by weight, preferably 0.01 to 3% by weight, and more preferably 0.1 to 1% by weight. If the content of the component (C) is less than 0.001% by weight, the desired improvement in finish cannot be sufficiently exhibited, while 5% by weight
If the ratio exceeds the above, the dispersion stability of the component (C) due to the component (A) and the component (B) becomes insufficient, the component (C) may precipitate, and the stability of the detergent composition may be reduced. It is not preferable because it is damaged.

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 commonly used as a detergent or an emulsifier as described above.

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. )

But are not limited to these.

Next, the (B) isotropic agent component used in the present invention will be described. The isotropic agent component (B) used in the present invention has a value of the intermolecular interaction parameter β obtained by the above formula (1) of -1 when mixed with a polyalkylene glycol type nonionic surfactant. It is a compound that is as small as 0.0 to 1.0 and is capable of optically isolating a 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.

Β = ln (αD ₁₂ / χ ₁ D ₁ ) / (1-χ ₁ ) ²

２ ₁ ² ln (αD ₁₂ / χ ₁ D ₁ ) = (1−χ ₁ ) ² ln

Is the interaction parameter between the molecule of the polyalkylene glycol-type nonionic surfactant and the molecule of the (B) isotropic agent component, where α is (A) the polyalkylene glycol-type nonionic surfactant in the solution phase. of the total amount of surfactant (B) and isotropic agent, represents the mole fraction of (a) polyalkylene glycol type nonionic surfactant, chi ₁ solves the above equation (2) Molar of (A) polyalkylene glycol type nonionic surfactant in the total amount of (A) polyalkylene glycol type nonionic surfactant and (B) isotropic agent required in mixed micelle Where D ₁ , D ₂ and D ₁₂ are (A) the critical micelle concentration of the polyalkylene glycol-type nonionic surfactant, (B) the critical micelle concentration of the isotropic agent, and the predetermined α, respectively. Mixed in Indicates the critical micelle concentration of the combined system. ｝

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 isotropic agent component (B) used in the present invention comprises:
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.
