Tablet Detergent Composition {DETERGENT COMPOSITION IN TABLET}

The present invention relates to a tablet detergent composition, and more particularly to a tablet detergent composition excellent in solubility.

Conventional detergents are mainly in the form of powders or liquids, so they do not get hygienic due to dirt on hands and use, and the inconvenience of using a measuring container. In order to solve this problem, recently, a technology for preparing tablets by tableting a certain amount of detergent has been developed.

Compared to conventional powder or liquid detergents, tablet detergents are easier to handle, do not get dirty when used, and are hygienic because they do not generate dust. In addition, there is an advantage that the metering container is not necessary separately, which is convenient and can prevent excessive use. When the tablet-type detergent is dissolved in the wash water to be quickly dissolved to appear when the washing effect appears, the washing effect appears, and the tablet strength is high to be transported and stored without being damaged.

However, in order to increase the tablet strength of the detergent, when prepared by applying a high tableting pressure to the detergent, there is a problem that the tablet strength of the detergent is high, but the tablet is not easily disintegrated. In addition, when manufacturing a detergent by reducing the tableting pressure in order to increase the disintegration of the tablet, there is a problem that the product value is low because the tablet strength is small and the product is likely to be damaged during transportation and storage.

British Patent Publication No. 2318575 A discloses sodium acetate and trihydrate (sodium acetate and 3H ₂ O) and sodium citrate and dihydrate (sodium citrate and 2H ₂ O) 7 to 50% by weight, and a water-soluble binder, 2 to 20 Disclosed is a tablet-type detergent having good disintegration properties, including weight percent, in particular the particle size of sodium acetate in the detergent composition of at least 0.3 mm. In addition, British Patent Publication No. 2320544 A uses a liquid phase having a viscosity of 1000 cP or less at room temperature so that the pore ratio of tablet detergents is 5% by weight or more, and sodium carbonate and sodium as water-soluble binders. A method for improving disintegration is disclosed using 15 to 85% by weight of citrate and the like.

However, the above manufacturing methods have a problem in that they are low in surfactant content, contain bleach, and are suitable for European washing conditions because they are suitable for drum washing machines. In the case of Korea, the washing time is short and the washing temperature is low, as well as different from the European washing conditions, there is a problem that it is not suitable for such a detergent.

In addition, Japanese Patent Application Laid-Open No. 9-87696 discloses a nonionic surfactant having a melting point of 40 ° C or lower, 10 to 35% by weight of an alkyl ester (AE) having an HLB of 9 to 16, and an oil absorption of 30 to 70 ml / 100 g. A tablet nonionic detergent containing 3 to 10% by weight of montmorillonite, active bentonite in the form of phosphorus Na, Ca is disclosed. The detergent is characterized by minimizing the dissolution of non-ion, but the fusion phenomenon between the non-ion and the builder (builder) occurs during compression, there is a problem that does not disintegrate when the tablet detergent is added to water.

In view of the problems in the prior art as described above, an object of the present invention is to provide a tablet detergent composition excellent in disintegration.

Another object of the present invention is to provide a tablet detergent composition having excellent solubility of particles after disintegration.

It is another object of the present invention to provide a tablet detergent composition which is excellent in disintegration and solubility of particles and excellent in aging stability.

Another object of the present invention is to provide a tablet detergent composition having excellent transport and storage properties.

The present invention, in order to achieve the above object, in the tablet detergent composition of the present invention, based on 100 parts by weight of the total detergent composition

a) 0.1 to 10 parts by weight of disintegrant; b) 0.5 to 15 parts by weight of lactose; c) 0.2 to 10 parts by weight of active bentonite; d) 2 to 25 parts by weight stability improver; And e) provides a tablet detergent composition comprising 3 to 30 parts by weight of salt.

Hereinafter, the present invention will be described in detail.

The present inventors have completed the present invention by finding that disintegration aids and dissolution accelerators are excellent in disintegration, stability, transport and storage when using a specific ingredient and a specific mixing ratio.

In the tablet detergent composition of the present invention, the disintegrant is preferably a polymer substance insoluble in water. Examples include starch and derivatives thereof such as corn, rice starch, potato starch, carboxylmethyl starch, sodium starch glyconate, and derivatives thereof; Cellulose and its derivatives include sodium carboxymehtyl cellulose, crosslinked cellulose, and fiber; Synthetic organic polymers and their derivatives as crosslinked polyvinyl pyrrolidone; And an inorganic substance may be used by mixing two or more kinds from the group consisting of clay or loess. More preferably cellulose or lignin which is characterized by expanding when in contact with water is preferred. The cellulose or lignin may be extracted and granulated other than wood or wood, the particle size is preferably 300 to 2000 ㎛. In addition, the materials that can be used as the disintegrant may be used by forming particles together with a material that can be mixed, such as inorganic / organic / water-soluble materials.

The content of the disintegrant is preferably 0.1 to 10 parts by weight, more preferably 1 to 8 parts by weight, based on 100 parts by weight of the total tablet detergent composition. When the content of the disintegrant is less than 0.1 part by weight, the disintegration power is reduced and the tablet may not be dissolved and may not function as a laundry detergent. When the content of the disintegrant exceeds 10 parts by weight, the detergent may be deteriorated. In addition, the disintegrant component may remain after washing because it contains a large amount of water-insoluble material, and there is a problem that the product price may be increased due to expensive raw material costs.

In the tablet detergent composition of the present invention, lactose acts as a disintegration aid. Lactose has its own disintegration ability, of course, when used in combination with a disintegrant to increase the disintegration power. In particular, since lactose is a water-soluble disintegration aid, the content of the water-insoluble disintegrant can be relatively reduced, thereby minimizing the residue of the disintegrant after washing to further improve the solubility of the product. The lactose of the present invention may use a derivative thereof. In addition, the lactose may be used by mixing with other materials capable of granulating the lactose. It is preferable that the particle size of lactose is 50-80 micrometers, and what is fine powder may be used. As the other granular material, a water-insoluble polymer, a water-soluble polymer, or an inorganic substance may be used.

In the present invention, the content of lactose is preferably 0.5 to 15 parts by weight, more preferably 1 to 10 parts by weight based on 100 parts by weight of the total tablet detergent composition. If the content of the lactose is less than 0.5 parts by weight may not function as a disintegration aid, when it exceeds 15 parts by weight may lead to an increase in raw material costs and lowering of the cleaning power.

The tablet detergent composition of the present invention includes active bentonite. The active bentonite is a substance that promotes dissolution so that disintegrated detergent particles can be dissolved in a short time, and serves to increase the cleaning power of the tablet detergent by dissolving the detergent particles once again after the tablet detergent disintegrates. do. In the present invention, the active bentonite may be used by mixing one or more from the group consisting of inorganic substances such as clay, montmorillonite, or talc, and materials usable as the disintegrant. The amount of the active bentonite is preferably used in an amount of 0.2 to 10 parts by weight, and more preferably 0.5 to 8 parts by weight, based on 100 parts by weight of the whole tablet detergent composition of the present invention. If the amount of the active bentonite is less than 0.2 parts by weight, the amount of use may be insignificant and may not function as a dissolution accelerator. If the amount is more than 10 parts by weight, detergent particles may not be properly formed, which is not preferable.

The present invention also includes a stability stabilizer over time. The stability stabilizer over time improves the stability over time of the tablet-type detergent, and serves to prevent the deformation of the tablet due to the infiltration of water, and thus the deterioration of quality even when stored for a long time. In the present invention, it is preferable to use silicates as stability stabilizers over time. The silicates include sodium silicate (Na-silicate), potassium silicate (K-silicate), layered silicate (Layered-silicated), meta-silicate, di-silicate, and silica. (silica) may be used alone or in combination of two or more kinds. The silicate has a water absorbing ability to prevent the degradation of the detergent due to water infiltration, and to prevent the fluctuation of the tablet, the alkalinity can improve the washing power of the detergent of the present invention.                     

The content of the stability agent over time is preferably 2 to 25 parts by weight, more preferably 5 to 15 parts by weight based on 100 parts by weight of the total tablet detergent composition of the present invention. When the content of the stability stabilizer over time is less than 2 parts by weight it may be difficult to store the tablet detergent for a long time, when it exceeds 25 parts by weight may not be well tableted because it is not preferable.

Tablet detergents of the present invention include salt. The salt has a high solubility and dissolution rate to increase the dissolution rate of the tablet, in particular, because the salt is well dissolved in water can promote the function of the disintegrant. In addition, the salt is an organic salt of sodium acetate trihydrate (sodium acetate 3 H ₂ O, sodium acetate anhydrate, potassium acetate, sodium citrate dihydrate (sodium citarate 2 H ₂ O) , Urea derivatives, and sodium succinate, and potassium chloride, which is an inorganic salt, may be selected singly or in combination of two or more thereof.

The salt content is preferably 0.5 to 40 parts by weight, more preferably 1 to 35 parts by weight based on 100 parts by weight of the total tablet detergent composition of the present invention. When the salt content is less than 0.5 parts by weight, the disintegration of the tablet detergent may drop, and when it exceeds 40 parts by weight, the disintegration is excellent, but the washing ability is relatively low, so that the washing agent may lose its original function. It can be undesirable.

In addition, the tablet detergent composition of the present invention may include a binder. The binder serves to increase the binding force of the tablet, in the present invention, the molecular weight of 1500 to 1800 polyethylene glycol (polyethylene glycol) or polypropylene glycol (polypropylene glycol), polyvinylpyrrolidone (polyvinylpyrrolidone), polyacrylate (polyacrylate), polymers such as water-soluble acrylate copolymers (acrylate copolymer), silicates, starch (starch) is preferably used. The binder may be used by dissolving a tablet in a detergent particle before spraying the tablet into a liquid and spraying, or adding and mixing the detergent particle itself with granulation.

The amount of the binder is preferably 0.1 to 10 parts by weight based on 100 parts by weight of the total tablet detergent composition of the present invention.

In addition, the tablet detergent composition of the present invention may include a lubricant. The lubricant acts not only to smoothly tablet tablet detergent during the process, but also serves as a lubricant to prevent the tablet from sticking to the tablet machine during tabletting. The lubricant may include calcium stearate, magnesium stearate, sodium benzoate, silica, talc, clay, silicate or zeolite ( zeolite). When the tablet detergent composition of the present invention comprises a lubricant, the amount of the lubricant is preferably 0.2 to 5 parts by weight based on 100 parts by weight of the entire tablet detergent composition of the present invention. When the amount of the lubricant is less than 0.2 parts by weight, the tablet may stick to the mold of the tableting machine, thereby reducing workability. When the amount of the lubricant is greater than 5 parts by weight, the tablet may not be easily manufactured by weakening the binding force of the tablet. It is not preferable because a lot of dust may blow and may adversely affect the working environment.

In addition, the tablet detergent composition of the present invention may include an anionic or nonionic surfactant. As the anionic surfactant, at least one selected from the group consisting of linear alkyl benzene sulfonates of Formula 1, fatty acid salts of Formula 2, alkanesulfonates of Formula 3, and alphaolefin sulfonates of Formula 4 Can be used.

Experimental Example: Performance Evaluation Experiment

In Example 1 and 2 and the tablet detergents of Comparative Examples 1 to 4, performance evaluation experiments were conducted under the following conditions. In order to reduce the experimental deviation for the performance evaluation of the tablet detergents of Examples 1 and 2, and Comparative Examples 1 to 4, 20 tablets of each tablet was evaluated and compared with the average value.

(Soluble evaluation)

 1 L of water at 25 ° C. was placed in a Terg-O-tometer, which is a washing power evaluation device, and one tablet of detergent of Examples 1 and 2 and Comparative Examples 1 to 4 was added thereto, and the stirring speed was 100 rpm for 10 minutes. Stirred. Next, the tablet was passed through a sieve of 270 mesh, the residual weight thereof was measured, and the solubility was evaluated by converting the residual ratio (%) relative to the initial weight. The solubility evaluation results are shown in Table 2 below.                     

(Degradability evaluation)

For the evaluation of disintegration, the tablet detergents of Examples 1 and 2 and Comparative Examples 1 to 4 were placed in a steel frame structure in which a tablet detergent was placed at a height of 10 cm in a 1 l beaker. The detergents were measured as the disintegration time of the cross-shaped bowl is completely disintegrated at the top and completely disappeared. The disintegration was evaluated by the disintegration time, and the evaluation results are shown in Table 2 below.

(Time stability evaluation)

The tablet detergents of Examples 1 and 2, and Comparative Examples 1 to 4 were left in a constant temperature and humidity chamber at a temperature of 30 ° C. and a relative humidity of 80% for 10 hours, and then the modified state of the tablets was visually examined by skilled subjects. Was evaluated. The evaluation results of aging stability are shown in Table 2 below, in which the state of almost no change in form is ○, the tablet has a strain of 20 to 50%, △, the tablet has a strain of 50% or more, and the state of being severely deformed × Indicated as.

As shown in Table 2, the tablet detergents of Examples 1 and 2 are excellent in solubility and hardly remain, and it can be confirmed that the disintegration time is short and easily disintegrates. In addition, the strain after aging also appears small, it can be seen that the stability over time.                     

On the other hand, the tablet detergent of Comparative Example 1, which does not use a disintegrant, was poor in both solubility and disintegration, and the tablet detergent of Comparative Example 2, which did not use lactose, was excellent in disintegration, but the disintegration time was slightly longer. . In addition, the tablet detergent of Comparative Example 3 without the use of active bentonite showed poor solubility, and the detergent of Comparative Example 4 without the time-lapse stability improving agent had a large deformation rate of the product, indicating poor transportation and storage. You can check it.

Since the tablet-type detergent composition of the present invention is excellent in disintegration but excellent in stability over time, it can prevent the quality degradation due to the penetration of moisture when transporting or storing for a long time. Thus, the disintegration power or solubility may show similar performance as the initial one, and the shape of the tablet may also be maintained.
