Description

Manufacturing method of capsule laundry detergent

The present invention relates to a method for producing a capsule laundry detergent.

Existing detergents have problems such as physical property and content deterioration due to interactions between moisture and other constituents in long-term storage of powdered detergents. For example, moisture in the air accelerates the cake of the powder and, in terms of solvent content, forms a complex between the zeolite and sodium silicate used in the powder detergent, producing a large, water-insoluble substance. . In particular, when the enzyme and bleach are mixed with detergent components, long-term stability tends to be inferior. If too much liquid is contained in the detergent in the powder detergent, the powder sticks, making it impossible to apply a large amount of liquid ingredient. In terms of use, it is difficult to weigh when using the detergent of the above type, which causes inconvenience in use due to the blowing of the powder, spillage or leakage of the liquid.

Accordingly, the present inventors can easily weigh and significantly reduce the deterioration of contents by measuring and packing detergent components in capsules with a detergent having a different concept from powder, liquid, and paste-type detergents. We have developed a capsule laundry detergent to provide.

The present invention is characterized in that a gelatine sheet prepared from a liquid mixed with a gelatin: water: elasticizing agent in a weight ratio of (1: 2.8: 0.2) to (1: 0.5: 1.5) as a shell and a laundry detergent as a content It relates to a capsule laundry detergent manufacturing method.

According to the invention, almost any type of solid, liquid and dough can be put into the contents of the capsule. Therefore, not only the ingredients of the finished prescription can be added, but also the enzymes, bleaches, etc., which are good to be sequestered in terms of long-term stability, can be preserved by encapsulating the substances. The problem can be solved by encapsulating liquid components that could not be applied at higher contents due to prescription problems in separate capsules, and by changing the ratio of gelatin, emulsifier, and water to change the surface properties of the capsule, that is, the degree of elasticity. It can give a time-releasing effect by controlling the time the capsule is dissolved in the aqueous solution.

More specifically, the capsule is divided into hard capsules and soft capsules according to the surface properties of the capsule. Hard capsules are suitable for powdery or granular materials, while liquid or dough-like materials are more elastic than capsules and soft capsules that are spherical or ovoidally encapsulated. First, the hard capsule is composed of a body and a cap made of gelatin, and in order to give elasticity to the body and the cap, sometimes a glycerin, gum arabic, or agar can be used, and a coloring agent and a light shielding agent are added to distinguish and preserve the contents. Can be. The soft capsule is a capsule that gives elasticity by using polyhydric alcohols such as glycerin and D-sorbitol in gelatin as a plasticizer. The components of the capsule should swell and dissolve easily in aqueous solution.

In the present invention, the sheet is prepared from a liquid in which a gelatin: water: elastizing agent is mixed in a weight ratio of (1: 2.8: 0.2) to (1: 0.5: 1.5) to prepare a gelatin sheet forming the envelope of the capsule. As a method of manufacturing the capsule for detergent, Hofliger & Karg inserting the raw material by (a) auger as shown in Figure 1, Hofliger & Karg inserting the raw material by DOS type (poison), Lilly type and (b) plunger. Type (c) Disc type (d) Disc type (d) Filling tube is inserted into the raw material and plunged into a plunger to make a slug and a capsule filled with Zanasi type capsules, Flat plate method of inserting raw materials between sheets and compressing them with a press, rotary method for preparing capsules for continuous introduction of two sheets by rotary and dispensing the contents with the metering pump as shown in Figure 2, and seamless seamless with liquid raw materials. There is a method for producing a soft capsule, such as a dropping method for producing a capsule.

All of the above production methods can be applied to the preparation of the capsule-type detergent, the production method may be applied differently in some cases. The amount of content contained in the capsule may be applied by first selecting the size of the capsule according to the concentration of the detergent content. In the actual laundry, when washing using a washing machine, the amount of water required at the time of washing is about 20 ~ 100ℓ, and depending on the detergent, the amount of detergent used is 10 ~ 200g. However, in general, about 30 to 100g at a time is the most used detergent.

The volume and capacity of the convenient capsule for metering when used depends largely on the physicochemical properties of the contents. Firstly, the dosage of the capsules is preferably 0.1 to 30 g, more suitably 0.5 to 10 g, unless the contents are separated separately. And the capsule volume is suitable from 0.2 to 40cc. However, the volume of the capsule is greatly affected by the specific gravity of the contents. In the case of separating the components of the contents separately in terms of long-term stability of the detergent, the volume and capacity of the capsule cannot be as large as in the above case for convenience and accuracy of weighing. Therefore, the dose is preferably 0.01 to 5 g and the volume is preferably 0.02 to 6 cc.

In the aspect of improving long-term stability among the detergent components, two or more capsules may be distinguished by adding color to the capsules when the components are properly separated.

In the present invention, the manufacturing method of the capsule for detergents is not limited to the above methods. The content of water is very important in the mixture of gelatin, elasticizing agent, and water for preparing the gelatin sheet. The water content is preferably 17 to 70 parts by weight. If the amount of water exceeds too much weight, the viscosity of the mixed liquid is lowered, and a sheet is not made, or the prepared sheet is too thin, which is not suitable for preparing capsules. If the content of water is 17 parts by weight or less, the viscosity of the swelling liquid is too high. Is difficult.

As mentioned above, an emollient is applied to give the capsule elasticity. The content of the emulsifier is 5 to 50 parts by weight. If the content of the emulsifier is too small, the elasticity of the capsule is too low, too much, making the capsule difficult. In addition, as the elasticizing agent that can be applied in the present invention, there are polyhydric alcohols such as gum arabic, agar, polyvinyl alcohol, glycerin and D-sorbitol.

In addition, the content of water of the prepared gelatin sheet is suitable 5 to 20 parts by weight. Because, if the content of water is too small, the capsule is brittle, and if too much, the surface properties of the capsule not only deteriorate but also may cause deterioration by moisture in the detergent contents. And the moisture contained in the gelatin sheet prepared by the appropriate content is very insignificant or does not affect the contents.

In addition to improving the long-term stability of the contents by packing the detergent components into one capsule or by dividing them into two or more capsules according to the nature of the ingredients, the metering on the use and the flow of powder or spilled liquid / Makes the user's environment comfortable by eliminating inconvenience caused by water leakage.

Hereinafter, although this invention is demonstrated based on a comparative example and an Example, these are not restrict | limited the technical scope of this invention.

Comparative Example and Example

Comparative Example 1

A powder slurry was prepared by spraying a detergent slurry (solid content: 60% by weight) containing a detergent composition having the ingredients and contents shown in Table 1 from the top of the countercurrent spray drying tower.

Table 1.

* Fluorescent Dye: Tinopal CBS-X

Example 1

According to the method for preparing a rotary capsule, a gelatin sheet was prepared by mixing a gelatin: water: arabic rubber: glycerin in a 1: 1.5: 0.1: 0.8 weight ratio, and the contents were prepared by adding 1 g of a detergent component of the comparative example. It was.

Example 2

A slurry was prepared by separating only sodium silicate from the detergent components of the comparative example, followed by spray drying to prepare beads. And the soda silicate and the bead-shaped particles were prepared in different capsules to prepare a capsule and mixed according to the content.

As a result of comparing the comparative example and the examples, there was no blowing of dust when used, and it was convenient to use, and it was much easier to measure the detergent during washing. In case of storage at room temperature, the comparative example caused cake formation when stored at a temperature of 30 ° C. and a relative humidity of 60% RH for a long time of 6 months to 1 year or more. Did not look.

As a result of comparing the comparative examples with Examples 1 and 2 in terms of long-term stability, the production of water-insoluble complexes between sodium silicate and zeolite in the Examples was not significantly reduced or shown in comparison with the Comparative Examples. Because the capsule avoids contact with the outside air, it prevents the acceleration of the complex formation by the moisture contained in the air. And as in Example 2, it is preferable to isolate components in terms of long-term stability.

In order to measure the influence of the gelatin sheet on the contents, the moisture content of Examples 1 and 2 and the formation of water-insoluble complex were measured under the same conditions. In the aspect of complex formation, the result was examined based on the above description, and it was found that the gelatin sheet had little influence on the change of physical properties of the detergent.

Therefore, applying capsules to laundry detergents will have many advantages such as long-term stability of the contents, aspects of use, and effective aspects. As a result of the panel of small groups, it was well received for the convenience of weighing and convenience.

Capsule laundry detergent prepared according to the present invention is a detergent of a different concept from the conventional powder, liquid, paste (type) detergent, and weighs the detergent components in the capsule, so that it is easy to weigh and remarkably deteriorate the contents. It can be reduced and also provides convenience for use.
