Description

  The present invention relates to a cleaning agent having excellent dispersion stability.

  In the cleaning agent, a solvent suitable for the object to be cleaned and various components are mixed, and the dosage form is taken into consideration for convenience in use. Particularly in recent years, liquid soaps and shampoos, laundry detergents and softeners, kitchen detergents, etc., tend to be liquid.

  Chelating agents, dispersants, surfactants, soaps, polysaccharides and the like are added to the liquid detergent. Each of these components has a function necessary for forming a cleaning agent, but by combining them, it may react with other components to cause an unexpected inconvenience.

  For example, when a detergent containing soap is used in hard water containing a large amount of metal polyvalent ions such as calcium ions and magnesium ions, these metal ions react with the soap to produce insoluble lime soap, which is to be cleaned. There has been a problem in that it has changed to yellow due to adhesion to the surface, causing unpleasant odors.

  In order to solve such a problem of lime soap, a chelating agent capable of sequestering metal ions is added, and a dispersant is further added to suppress aggregation of the generated lime soap. ing.

  Also, laundry detergents contain enzymes such as proteases and cellulases. Protease is added to remove protein stains, and cellulase is added to decompose and remove cellulosic substances from stains and dirt that have entered the fiber.

  In this way, various components are added to the cleaning agent, but since various components with different properties are used in combination, the stability of the entire cleaning agent is improved while suppressing the influence between each component. In addition, there are various problems such as inability to use ingredients that excessively damage the skin and the object to be cleaned while maintaining the cleaning power and foaming feeling.

  In order to solve the problems related to the cleaning agent, various methods have been studied. Specifically, a cleaning agent containing a copolymer of dimethyldiallylammonium chloride and (meth) acrylamide, such as polyoxyalkylene alkyl ether sulfate, specific silicone compound, aromatic carboxylic acid or salt thereof, and cationized cellulose. A detergent composition (Patent Document 2) containing a composition (Patent Document 1), a polysaccharide containing soap and uronic acid (Gatti gum, gum arabic, soybean extract water-soluble hemicellulose, etc.), and an alkyl sulfate A liquid detergent for clothes (Patent Document 3), a solid oxidizing agent, preferably sodium perborate, and an alkali metal borate, boric acid, alkali metal chloride, or a mixture thereof. A phase-stable liquid detergent (Patent Document 4), a surfactant, an organic chelator, A cleaning agent (Patent Document 5) containing an enoic acid salt or a salt thereof and a regulator as a bulking agent, and a component derived from a natural product as a main component (Patent Document 5), a specific nonionic surfactant and an amino acid derivative as essential components A cleaning composition (Patent Document 6) and the like are disclosed.

  However, it is possible to solve the problems of cleaning agents (for example, imparting long-term stability, improving cleaning power, etc.) by using the above technology, but the added components diversify chemically synthesized products. There was a trend. Although these components have a significant effect on stabilizing the cleaning agent and the like, the influence on the natural environment after use cannot be ignored, and studies for suppressing its use are necessary.

  The inventor of the present application has conducted intensive research to solve the above-mentioned problems, and in order to improve the stability of the detergent, by using fermented cellulose that is naturally decomposed, the stability obtained in the prior art The inventors have reached the knowledge that the same effect can be imparted and the influence on the natural environment can be suppressed, and the present invention has been completed.

  According to the cleaning agent of the present invention, while having the same properties as the conventional cleaning agent, the components contained in the cleaning agent, in particular a scent and cleaning component, a granular gel containing a moisturizing component, a decorative lame and the like Even relatively large solids such as beads can be stably dispersed. Even when such components can be stably dispersed, a cleaning agent capable of suppressing the influence on the natural world can be provided.

  The fermented cellulose used in the present invention is obtained by industrially agitating and agitating acetic acid bacteria and separating and recovering very thin fibrous cellulose made from the cells. An example of a commercially available product is the Sun Artist [Trademark] series of Saneigen FFI Co., Ltd.

  The amount of fermented cellulose added can be appropriately adjusted according to the type and amount of components to be dispersed in the cleaning agent and the specific gravity of the solid matter, but generally 0.01 to 2% by mass, preferably Is 0.03-1 mass%. When the added amount of the fermented cellulose is 0.01% by mass or less, a preferable dispersion effect cannot be obtained, and when 2% by mass or more is added, the viscosity becomes high and handling at the time of use may be difficult.

  The method of adding fermented cellulose to the cleaning agent is only required to add fermented cellulose as one raw material of the cleaning agent to be prepared, and since there is no particular limitation on the timing of addition or temperature conditions, use a normal cleaning agent production line There is a merit that can be done.

  The cleaning agent according to the present invention can utilize various conventionally used components without limitation, except that fermented cellulose is an essential component. For example, soaps such as solid soap, powdered soap, composite soap; anionic surfactant (linear alkylbenzene sulfonate, alkyl sulfate ester, α-olefin sulfonate, ether sulfate ester, alkylphenyl polyethylene glycol ether, Alkyl polyethylene glycol ethers), nonionic surfactants (polyoxyethylene alkyl ethers, fatty acid alkanolamides, alkyl polyglucosides, etc.), cationic surfactants (di-long chain alkyl type quaternary ammonium salts, mono long chain alkyl quaternary salts) Grade ammonium salts), amphoteric surfactants (alkyldimethylaminoacetic acid betaine, fatty acid amidopropyl betaine, etc.), etc .; inorganic builders (various zeolites, amorphous aluminosilicates, sodium pyrophosphate, Acid sodium, crystalline sodium silicate, sodium sulfate, sodium tripolyphosphate, etc.), organic builder (aminocarboxylate, hydroxyaminocarboxylate, hydroxycarboxylate, cyclocarboxylate, ether carboxylate, organic carboxylate) Detergency aids such as polymers); alkaline agents such as carbonates, silicates, phosphates, borates and amines; enzyme agents such as proteases, lipases and amylases; recontamination such as carboxymethylcellulose and polyethylene glycol Inhibitors; moisturizing components such as chondroitin sulfate, hyaluronic acid and collagen; other bleaching agents, softening agents, foam control agents, fluorescent brighteners, reducing agents, fragrances, pigments, antibacterial agents and the like can be blended.

  In addition to fermented cellulose, one or more of gum arabic, locust bean gum, xanthan gum, karaya gum, guar gum, tragacanth gum, gati gum, alginic acid and its salts, starch, hyaluronic acid, pectin, gellan gum, karaya gum, water-soluble hemicellulose These can be used in combination as long as the effects of the present invention are not hindered.

  Furthermore, in the present invention, it is possible to stably disperse the solid material in the cleaning agent. As an example of such a solid material, it is possible to add a granular gel containing the above-described cleaning component, fragrance component, enzyme, or the like, lame added for decoration purposes, or plastic beads to the cleaning agent. Conventionally, there are particles in which a granular gel is contained in the cleaning agent or a decorative lame is dispersed, and if it has a small mass like lame, it has been dispersed in the cleaning agent, In some cases, precipitation occurred. If the granular gel is larger than lame, it easily settles on the bottom of the container immediately, and it is necessary to take measures such as shaking it when using it. However, when the detergent is shaken and used, unnecessary foaming occurs and inconvenience occurs during use. Therefore, it is not possible to expect any effect due to the added granular gel. Alternatively, there is also one in which a high molecular weight polymer is added to float a granular gel, but the viscosity is as high as about 2000 to 3000 mPa · s, and the influence of the components used on the environment becomes a problem. There is a fear.

  In the present invention, when added to a conventional cleaning agent, even a granular gel that sinks to the bottom of the container and is difficult to use can be stably and uniformly dispersed throughout the cleaning agent. In addition, even when decorative lamé and beads are stored for a long period of time, it can be kept uniformly dispersed throughout the cleaning agent.

  Here, an example of a solid material that can be added to the cleaning agent, specifically, a granular gel containing a scent component and a cleaning component is given. As a scent component that can be added to the granular gel, a scent component generally used for perfume can be used without limitation. Specifically, regardless of natural or synthetic, lemon flavor, orange flavor, pine flavor, sandalwood flavor, lavender flavor, geranium flavor, citronella flavor, lemon grass flavor, jasmine flavor, lilac flavor, rose flavor, rosemary flavor, A lime fragrance | flavor etc. are mentioned and 1 or more types of these can be used.

  Furthermore, chondroitin sulfate, hyaluronic acid, collagen and the like can be added as a moisturizing component.

  Moreover, it becomes possible to enjoy different detergency with one detergent by adding one or more of the aforementioned detergents to the granular gel.

  In order to prepare the granular gel, the gel can be easily prepared by using various thickening polysaccharides. Specifically, a thickening polysaccharide such as xanthan gum, gellan gum, carrageenan, guar gum, agar, gelatin, pectin, tamarind seed gum, glucomannan, water-soluble soybean hemicellulose, and alginic acid is mixed with an aroma component or a cleaning component to gel. A granular gel can be obtained by crushing the gel. Alternatively, by preparing a solution in which a gelling agent having calcium reactivity such as gellan gum, alginic acid or pectin and a fragrance component or a cleaning component are mixed, and dropping the prepared solution into a solution containing calcium, A gel can also be obtained.

  Further, the solid matter suspended in the cleaning agent according to the present invention is not limited to the above-mentioned granular gel, but is a capsule having a coating prepared by a known method, a cut plastic piece or a lamellar. Plastic or nylon beads may be used.

  In the prior art, it is known that carboxymethyl cellulose is added to the cleaning agent as an anti-redeposition agent (for example, described in Patent Document 4). This is because the dirt removed by cleaning adheres to the cleaning object again. It is added in order to prevent this. As also shown in the experimental examples described later, carboxymethylcellulose did not have a dispersion stabilizing effect like fermented cellulose used in the present invention.

  EXAMPLES The present invention will be described below with reference to examples, but the present invention is not limited to these examples. In the following formula, unless otherwise stated, “%” means “mass%”. "*" In the text indicates that it is a registered trademark of San-Ei Gen FFI Co., Ltd., and "*" means that it is a product of San-Ei Gen FFI Co., Ltd.

Experimental example 1
A granular gel was added to a commercially available cleaning agent, and the dispersion stabilizing effect of fermented cellulose was examined.
<Preparation of fermented cellulose solution>
Sun Artist * (fermented cellulose preparation) * manufactured by San-Ei Gen FFI Co., Ltd. was added to water, and after stirring with a propeller, homogenized (150 kgf / cm ² ) to prepare a fermented cellulose solution.

<Evaluation method>
The fermented cellulose solution and nylon beads (19 mg / piece) were added to a commercially available cleaning agent, and the dispersion state of the beads after standing for 1 day was visually confirmed. The addition amount as the fermented cellulose added to each Example product is described for each. The results are shown in Table 1.

<Result>
From the above experiments, it was revealed that nylon beads can be stably dispersed in the detergent by adding fermented cellulose. In Example 3, the nylon beads were dispersed, but the nylon beads tended to sink slightly downward compared to the other examples. However, compared with the fact that the viscosity of the product in which the lame is dispersed with the existing cleaning agent is 2000 to 3000 mPa · s as described above, it is clear that the product can be dispersed in a much lower viscosity state. It became.

  From the above results, it is possible to stably float nylon beads in the cleaning agent in the commercially available cleaning agent, so that decorative nylon beads are added and various fragrance components and cleaning components are contained. It becomes possible to prepare a granular gel and provide a detergent with a new added value to which this is added.

Experimental example 2
In place of the fermented cellulose solution, the dispersion state of the beads when other polysaccharides were used to give the same viscosity was examined.

<Evaluation method>
A solution in which the amount of fermented cellulose prepared in Experimental Example 1 was adjusted to 0.03%, 0.05%, 0.1%, and 0.5% and the polysaccharide aqueous solution shown in Table 2 had the same viscosity. Each solution was prepared (cooled after heating at 80 ° C. for 10 minutes and then cooled), and each was mixed with a detergent (“Liquid Attack” manufactured by Kao Corporation) with propeller stirring, and nylon beads (0.27 mg / piece) ) Was added, and the dispersion state of the beads was visually confirmed (added 17 g of fermented cellulose solution or polysaccharide aqueous solution to 83 g of the cleaning agent).

<Result>
From the above experiment, it was revealed that the fermented cellulose solution was suitably mixed with the detergent compared to the polysaccharide, and the added beads were stably dispersed although the amount of the fermented cellulose increased slightly when it was added. In addition, the fermented cellulose exhibited a sufficient dispersion stabilizing effect even at an addition amount of 0.03% (Example 4). On the other hand, one of the polysaccharides was affected by the ingredients in the cleaning agent or produced a gel (Comparative Examples 6 and 7), and was not mixed so that no dispersion effect was obtained (Comparative Examples 4, 5, and 8). Results were obtained.
Experimental example 3

  Patent Document 4 and the like describe that carboxymethylcellulose (CMC) is used as an anti-redeposition agent for laundry detergents. The fermented cellulose which concerns on this invention was compared with the effect.

<Evaluation method>
The viscosity of the CMC solution was adjusted to the same level and added to the cleaning agent, and the dispersion effect was visually confirmed using the same beads as in Experimental Example 2. This was compared with Example 7 prepared in Experimental Example 2 of the product of the present invention. The results are shown in Table 3.

<Result>
From the above results, it was revealed that CMC added as an anti-redeposition agent to laundry detergents does not have a dispersing effect on beads and the like.
