DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail based on embodiments. Detergent composition of Example 1 Example 1, sodium palmitate 1
~ 30% by weight, salt 2 ~ 15% by weight, rice bran 0.5 ~
It contains 10% by weight and 45 to 96.5% by weight of water.

More specifically, for example, a rice bran 1 solution is prepared by dissolving 30 g of sodium palmitate in 50 g of water.
Add 0 g and heat to about 80 ° C., then slowly add 10 g of salt with stirring and cool naturally to room temperature with stirring, or forcibly cool with stirring to obtain palmitic acid or palmitic acid. An encapsulated rice bran powder coated with either or both of the sodium salts is produced, and the encapsulated rice bran powder can be manufactured as a detergent composition in which the powder is substantially uniformly dispersed. Then
When the obtained detergent composition is centrifuged, for example, and the insoluble fraction is separated, an encapsulated rice bran powder is obtained. Although rice bran is originally like a powder, it is preferable that the rice bran be dried once, re-pulverized, and reprocessed into a finer powder.

In place of rice bran, the above “natural product powder”
By using a single or a mixture of a plurality of these, various encapsulated "natural powders" and a detergent composition in which these are substantially uniformly dispersed can be produced.

Although the detailed mechanism of this phenomenon is not clear, the change in solubility due to a decrease in temperature and the effect of salting out of salt are combined to make palmitic acid or sodium palmitate difficult to dissolve and become insoluble. It can be guessed that this is because it adheres to the surface of.

The detergent composition of Example 2 Example 2, potassium palmitate 1
30% by weight, 2 to 15% by weight of salt, and 0% tea and leaf powder.
It contains 5 to 10% by weight and 45 to 96.5% by weight of water.

More specifically, for example, 15 g of salt is slowly added with stirring to a solution prepared by dissolving 20 g of potassium palmitate in 55 g of water, and then 10 g of cooled or frozen tea branch leaf powder is slowly added with stirring. Then, an encapsulated tea foliage powder whose entire surface is coated with palmitic acid or potassium palmitate or both is produced, and it can be manufactured as a detergent composition in which the encapsulated tea foliage powder is substantially uniformly dispersed. Subsequently, when the obtained detergent composition is centrifuged, for example, to separate the insoluble fraction, an encapsulated tea branch leaf powder is obtained. It is preferable that the tea leaf powder is also re-pulverized and re-processed into a finer powder.

When the above-mentioned “natural product powder” is used alone or in combination of a plurality of types instead of tea branch and leaf powder, various encapsulated “natural product powders” and detergents in which these are almost uniformly dispersed are used. A composition can be manufactured.

The encapsulation mechanism of the present tea branch leaf powder is as follows.
The tea or leaf powder, which has been cooled or frozen beforehand, is added to an aqueous solution containing salt at a salting-out concentration or less necessary for salting out the fatty acid salt while stirring, so that only the solution portion around the tea and leaf powder is abrupt. Is cooled. Then, it can be inferred that the solubility of the fatty acid salt is reduced in this solution portion, and the salting-out effect of the salt is added, so that the fatty acid salt becomes insoluble and adheres to the entire surface of the tea branch leaf powder.

The detergent composition of Example 3 Example 3, and 1 to 30 wt% of sodium polyoxyethylene lauryl ether sulfate, sodium chloride 2
15 wt%, aloe leaf 0.5-10 wt%, water 45
９６96.5% by weight.

More specifically, for example, 1.5 g of sodium polyoxyethylene lauryl ether sulfate and sodium chloride 1
1 g was slowly added to a solution of 77.5 g of water, and the mixture was heated to about 80 ° C. Then, 10 g of aloe leaf powder, which had been cooled or frozen in advance, was added with stirring and allowed to reach room temperature with stirring. Cooling or forcibly cooling with stirring produces an encapsulated aloe leaf powder, the entire surface of which is coated with polyoxyethylene lauryl ether sulfate or sodium polyoxyethylene lauryl ether sulfate or both, and the encapsulated aloe leaf powder is produced. It can be manufactured as a detergent composition in which leaf powder is dispersed almost uniformly. Then, the obtained detergent composition is centrifuged, for example, to separate an insoluble fraction, whereby an encapsulated aloe leaf powder is obtained.

When the above-mentioned “natural product powder” is used alone or in combination of a plurality of kinds instead of the aloe leaf powder, various encapsulated “natural product powders” and detergents in which these are almost uniformly dispersed are used. A composition can be manufactured.

[0043]

As described above, according to the method for producing a detergent composition of the present invention, encapsulated "natural powder" encapsulated with a surfactant and "natural powder" encapsulated with a surfactant. The formulated detergent composition can be produced very simply and at low cost.

Next, according to the cleaning composition of the present invention,
In addition to the excellent functions and effects such as the cleaning action and the foaming property of the conventional detergent mainly composed of a higher fatty acid salt derived from nature, the following special effects can be obtained.

First, the surface of the “natural product powder” is encapsulated with a surfactant, thereby preventing the “natural product powder” from being rancid, spoiled, and stimulated by air (oxygen). Release of odorous and odorous gases.

In addition, since an insoluble "natural powder" is blended, a massage effect is obtained at the time of use, whereby the skin after use feels moist without stretching.
It is possible to obtain a very effective operation and effect, such as being able to finish in a slippery state.
