Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a W / O type shoe cream, and more particularly to a method for producing a W / O type shoe cream in which a small amount of water is dispersed in wax. .

[0002]

2. Description of the Related Art Conventionally, W / O type shoe creams that have been tried and tested contain 40 to 50% of water and a maximum wax content of about 20%.
Therefore, it is difficult to stabilize. For this reason, it is considered that the water is contained by using a surfactant, but in order to stabilize the water by containing the water, the surfactant is inevitably used excessively. This type of W / O type shoe cream is not currently sold in the market due to its poor properties and gloss effect and the need for large-scale equipment such as high-speed stirring and cooling devices.

Further, a general emulsifying shoe cream is made of a soft paste and is easy to use and has a wide variety of colors. However, it is water-soluble, so that it has a gloss effect and a water resistance. Is inferior to oily shoe cream. On the other hand, oil-based shoe cream has the drawback that it is harder than the emulsifiable shoe cream, and thus is not easy to use,
It has various defects such as solvent separation due to temperature change, evaporation, and restrictions on the type of container. Therefore, the emulsifying shoe cream is predominant in the market.

[0004]

The present invention overcomes the disadvantages of the emulsifying shoe creams and oily shoe creams described above, and
The purpose is to utilize each of these strengths to achieve a high gloss effect and enhance its sustainability.

[0005]

Means for Solving the Problems The present invention has been proposed in order to achieve the above-mentioned object, and a surfactant is added to a mixed solution of a molten wax and an organic solvent and stirred, W / 5-15% of water is added to disperse W /
The present invention provides a method for producing an O-type shoe cream.

[0006]

Function: The melted wax and the organic solvent are mixed well. Therefore, a surfactant is added to this mixed solution, and the mixture is stirred to evenly distribute the surfactant. And
By adding 5 to 15% of water, the water is absorbed and dispersed by the surfactant distributed in the solution,
A stable W / O shoe cream is produced. In this way, it becomes possible to disperse a small amount of water uniformly, thus suppressing the crystallization of the wax. Therefore, even if a large amount of high molecular weight ester wax having a high gloss effect is used, a soft paste W / O type shoe cream can be manufactured by a simple manufacturing method.

[0007]

EXAMPLE An example of the present invention will be described in detail below. First,
The present invention was made by using an oily shoe cream and focusing on the point that the polishing and polishing effects are improved by adding a small amount of water when polishing, but based on this point An experiment was conducted on the production of a shoe cream in which a small amount of water was dispersed in an oily shoe cream, and it was found that polyoxyethylene sorbitol tetrachloride as a nonionic surfactant was added to a mixed solution of dissolved wax, solvent mineral spirit and turpentine oil. It has been found that 5 to 15% of water can be dispersed with particles of about 1 micron by using stearate and polyoxyethylene monostearate in a specific ratio.

According to the method of the present invention, it is possible to disperse water in most waxes, and when a large amount of water which has been tried so far is used, the shoe cream is hardened,
Although it becomes a destabilizing factor, it is possible to use a high-molecular-weight wax where the polishing effect is extremely high. Furthermore,
A trace amount of polyoxyethylene stearyl ether, sodium lauryl sulfate and stearyl alcohol as a surfactant and 1 to 2% of ethylene glycol or propylene glycol are added and uniformly distributed, and 5 to 15% of the surfactant is added. A stable W / O type shoe cream can be obtained by dispersing the water.

Therefore, in the present invention, the wax is used in the specified ratio at the same time when the surfactant and the additive are selected. That is, by using a combination of ester wax synthesized from high molecular weight hydrocarbon, ester wax synthesized from montanic acid, microwax, paraffin wax, and insect wax, it has a high gloss effect and water resistance in a soft paste. A W / O type shoe cream is obtained.

In the present invention, water is dispersed in an amount of 5 to 15%. However, it is possible to make the performance equal to or higher than that of oily shoe cream having a high gloss effect, and to use the small amount of water. This is because the wax coating film is cooled by the heat of vaporization to become a coating film having a high density when the shoe cream is used, and the durability of the polishing effect is enhanced. Further, when the water content is 15% or more, the glossing effect is lowered, and at the same time, it takes a considerable amount of time to polish and it is difficult to polish the shoe cream.

Further, in the present invention, a hydrocarbon organic solvent is used together with the wax. However, if the wax concentration is too high, the wax becomes solid and lacks extensibility. Therefore, it is because it was avoided in advance that it would not be suitable for use as a shoe cream. Also, as the solvent, mineral spirit and turpentine oil are used, but it was adopted in consideration of the solubility of the colorant and the high boiling point of 150 to 200 ° C., flammability, toxicity and the like. However, any of them may be used and should not be limited to the above.

The amount of wax used in the present invention is 28.
~ 29%, solvent amount about 50-55%, activator amount 4-5
% Has been found to be optimal, but should not be limited to this. That is, the ratio of the amount of the wax to the solvent is that given above due to the extensibility in use and the ease of polishing, and the effect of the surfactant increases even if the amount is increased. Does not increase, it becomes uneconomical if used excessively, and in turn, it causes deterioration of water resistance.

Further, in the present invention, the above-mentioned surfactant is added to the mixed liquid of the above wax and solvent, and the mixture is 80-85.
Although 5 to 15% of warm water is dispersed at ℃, water may evaporate at higher temperature, and wax may precipitate at 80 ℃ or less, thus deteriorating the stability of the product. Therefore, the above temperature was found to be the most appropriate.

Thus, according to the above-mentioned production method of the present invention, water can be uniformly dispersed by the action of simply mixing, as long as there is a device capable of melting the wax, and the produced cream is liquid. Or, it can be poured into a container even if it is in paste form. In addition, a soft paste W / O type shoe cream can be obtained by leaving it to stand at room temperature without requiring a special cooling device. Thus, in selecting the material of the container, any material can be used as long as it can withstand mineral spirits and turpentine oil.

The W / O type shoe cream thus obtained maintains a soft paste state even at 0 ° C.
Even at a high temperature of 45 ° C., the solvent and water are not separated and liquefied, and the shoe paste is a very stable soft paste. Further, the manufacturing process is extremely simplified and no special equipment is required, which contributes to cost reduction.

INDUSTRIAL APPLICABILITY The present invention uses a surfactant in a mixed solution of a dissolved wax and a hydrocarbon-based organic solvent to add 5 to 5 parts of water.
Since it was dispersed by 15%, the water could be uniformly dispersed with particles of about 1 micron. Thus, the present invention has the following effects. Even if a large amount of wax with a high gloss effect is used, a soft paste and stable shoe cream can be made, and since a small amount of water is used, the wax coating film is cooled by the heat of evaporation of water during use. As a result, the coating film has a higher density, and the polishing effect and its sustainability are enhanced. As it has the same level of water resistance as oil-based shoe cream,
Wax loss due to rain or the like is reduced, and as a result, durability of gloss is improved. The solvent does not separate due to temperature changes and changes with time, and the amount used is small, so the product has a long life and is economical. Since both water-soluble and oil-soluble colorants can be used,
Similar to general O / W shoe cream, it has a wide variety of colors. The leather to be used always contains water, and it can be expected to have a leather-retaining effect of keeping the flexibility of the leather as compared with oil-based shoe cream. Furthermore, since the manufacturing process is extremely simple, no special equipment is required, which also contributes to cost reduction.
