Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a novel composition of a viscous lotion.

[0002]

2. Description of the Related Art Conventionally, oil-based lotions have been used because of their good sliding feeling on the skin. However, they have a drawback that they give a slimy feeling during use and are difficult to wash with water after use. was there. For this reason, recently, as it is used as a food additive, it can be used safely, and since it is relatively easy to wash with water after use, lotions containing starchy or seaweed extract components as main components have been used. It is used as a liquid lotion for massage and ultrasonic echo.

[0003]

However, the above-mentioned lotion containing a starch or seaweed extract as a main component has a glue-like shape, so that it easily clogs into the pores of the skin. Due to the property of being easily solidified, it is difficult to eliminate it, and there is a disadvantage that its main component is putrefactive. For this reason, the residue clogged in the pores may rot or generate mold, which often causes rough skin. In addition, preservatives, stabilizers, preservatives and the like may be blended to prevent the decay and the like, but additives such as the preservatives may cause symptoms such as rough skin and melasma. There is a disadvantage that there is also.

Therefore, according to the present invention, there is obtained a feeling of use having no slimy feeling and a good sliding feeling, and a residue clogged in pores with water can be easily washed away, and furthermore, it is safe to use, Another object of the present invention is to provide a viscous lotion comprising a composition suitable for long-term storage.

[0005]

In order to achieve the above object, the viscous lotion of the present invention comprises one or more selected from locust bean gum and xanthan gum, dextrin and water. It is characterized by the following.

In the above composition of the present invention, one or more selected from locust bean gum, carrageenan or xanthan gum generates a viscous fluid by reacting with water in the presence of dextrin. At this time, the dextrin works to increase the viscosity of the viscous fluid to a state suitable for a lotion and stabilize the viscosity.

[0007] That is, locust bean gum, carrageenan or xanthan gum, or a mixture of one or more of these, has a property of causing the aqueous solution to become viscous by a reaction with water itself. If the mixing amount is too small, the viscosity becomes too small, and if the mixing amount is too large, it becomes a gel-solidified state, and in any case, it is difficult to obtain a viscous fluid suitable for a lotion. . In other words, in this case, the range of the mixing amount with water in which a viscous fluid suitable for the lotion can be obtained is extremely limited. This is the same in the case of dextrin. In the case of dextrin, even when a relatively large amount thereof is mixed with water, a viscosity suitable for a lotion cannot be obtained.

Further, since the viscosity of the lotion of the present invention is enhanced and stabilized by dextrin, the lotion can be easily removed from pores or the like by rinsing with normal temperature water or warm water after use. Can be eliminated. For this reason, it does not remain in a state where the pores are clogged.

Further, since locust bean gum, carrageenan or xanthan gum and dextrin have been conventionally used as food additives,
It is safe against the skin and even if it enters the mouth.

[0010] Further, as described above, the compounding of dextrin exerts a stabilizing effect on the viscosity of the lotion, so that it is not necessary to separately add a stabilizer or the like as in the conventional product. Therefore, it does not cause troubles such as rough skin caused by such additives, and since these additional components are not separately required,
There are advantages that can be used more economically.

The viscous lotion of the present invention is not particularly limited. However, the total amount of locust bean gum, carrageenan, carrageenan or xanthan gum or a mixture of one or more of these with dextrin is preferred. Is preferably 1% by weight or more and 10% by weight or less of the whole lotion agent. If the amount is less than 1% by weight, sufficient viscosity as a lotion cannot be obtained, and if the amount exceeds 10% by weight, the viscosity tends to be too large as a lotion. However, as a lotion for massage, since the point of sliding feeling is particularly important, 3 to 6
%, And the range of 6 to 8% by weight is more preferable as the ultrasonic echo lotion agent, since the characteristics of the spread film are particularly important.

The mixing ratio of locust bean gum, carrageenan or xanthan gum or a mixture thereof and dextrin is not particularly limited. However, in view of the stability of the initial viscous state, locust bean gum, It is preferable that the dextrin is contained in a proportion of 2 parts by weight or more and less than 4 parts by weight with respect to 1 part by weight of one or more selected from carrageenan and xanthan gum.

In this range of the mixing ratio, a viscous state suitable for use as a lotion can be obtained, and the viscous state is maintained for at least a certain time (at least 3 hours) after preparation suitable for use. It is. If the mixing ratio is less than 1 to 2 parts by weight, a viscosity state required as a lotion cannot be obtained. If the mixing ratio exceeds 1 to 6 parts by weight, depending on the storage temperature, the time required to maintain the initial viscosity may be obtained. May be too short for use.

[0014] In addition, these compounding ratios, especially, 1 to 2
When the amount is in the range of 4 to 4 parts by weight, the viscosity can be maintained for a longer time after preparation,
More preferred. As described above, for the lotion of the present invention, the initial viscous state is maintained for a certain period of time after the adjustment, but after the certain period of time, the viscosity tends to decrease with time. Becomes Although the cause is not clear, it is considered to be due to deterioration of the lotion component, and it is recognized that the tendency of the viscosity to decrease increases as the blending ratio of dextrin increases and the storage temperature increases. It is recognized that the temperature dependence of the viscosity decrease is particularly remarkable when the storage temperature is 30 ° C. or higher. However, by setting the mixing ratio of each component described above, such a defect can be further improved. Because it can be.

The above-mentioned viscous lotion of the present invention can be produced by mixing locust bean gum or the like and dextrin in order, or mixing and mixing the mixture in warm water of 30 ° C. or higher, preferably 40 ° C. or higher. In addition,
When the water temperature is lower than 30 ° C., it takes a long time to form a viscous fluid.

The present invention also includes a composition having a composition in which the initial PH value of the preparation is adjusted to a range of 7.5 or more and 8.0 or less. That is, as the above-mentioned viscosity decreases with time, the pH value of the lotion agent also decreases, and the initial weak alkaline (PH 7.0 to 7.5) is weakly acidified (PH 6 to 6. 5) Yes. Accordingly, the pH value of the lotion agent is set to 7. so that the weak alkaline property is maintained for a longer time.
It is adjusted so as to increase the value to 5 or more and 8.0 or less.
According to this lotion agent whose PH value has been initially adjusted, with the weakly alkaline state being maintained for a long time,
The effect of further improving the stability of the viscous state is exhibited.

In this case, the range of the PH value is limited by the fact that the lotion prepared under the above-mentioned ordinary conditions exhibits a PH value of about 7.5. It is not preferable to do so because there is no point in adjusting the PH, and if the adjusted PH value exceeds 8.0, the skin surface may be adversely affected.

A lotion having a composition with an initially increased PH value can be easily obtained by adding an alkaline agent such as caustic soda or caustic potash, which is less likely to damage the skin. in this case,
The powder of the alkaline agent can be prepared as a mixture prepared by mixing the powder of locust bee gum or the like or the powder of dextrin. Alternatively, a separately prepared diluted alkaline aqueous solution may be supplied.

Locust bean gum, carrageenan, xanthan gum, and dextrin are in powder form at normal temperature. Therefore, each of these components can be used in the form of being separated from water and dissolved in warm water each time it is used. According to such a method of use, locust bean gum, carrageenan or xanthan gum or a mixture of one or more of these, and dextrin, and in some cases, an alkaline agent can be stored in a stable state as a powder. Therefore, it is suitable for long-term storage.

[0020]

Next, embodiments of the present invention will be described. (Examples 1 to 19) 100 g, 150 g, 200 g, or 280 g of dextrin D powder was uniformly mixed with 50 g of locust bee gum A, carrageenan B, and xanthan gum C, respectively, to obtain admixtures, respectively. Next, 12 g of each of these mixed agents was added to 40
℃ warm water, stir this with a spatula, 200ml
Lotions were prepared (Examples 1-1)

6.5 g, 16.5 g of carrageenan B powder and 16.5 g of xanthan gum C powder were uniformly mixed with 150 g of dextrin D powder to obtain admixtures, respectively. , And stirred with a spatula to prepare 200 ml of lotion preparations (Examples 16 to 19).

Each of these lotions was used as a sample, immediately after its preparation, and stored in a beaker at room temperature (25 ° C.).
C.), the viscosity was checked 3 hours after the preparation and 24 hours after the preparation, and the results were shown in Table 1.
It was shown to.

[0023]

[Table 1]

In the test of the viscous state, 5 g of the prepared lotion was rubbed against the skin surface of a human, and the slipping feeling at that time was confirmed. That is, when the lotion had good viscosity as a massage lotion, it was evaluated as ○, when it could be used as a lotion, but when the viscosity was low, and when it had little viscosity or was unsuitable as a lotion, ×.

Locust bee gum A, carrageenan B, xanthan gum C and dextrin D powder 12
g was added to warm water at 40 ° C., respectively, and the mixture was stirred with a spatula to prepare 200 ml of each solution, and these were used as comparative samples (Comparative Examples 1 to 4).

From the results shown in Table 1, all of the samples of Examples 1 to 19 according to the present invention were obtained as having a good viscous state.
It can be confirmed that the initial viscous state is maintained.
In addition, the viscous state of these samples was determined in Comparative Examples 1 to 4.
It can be seen from the comparison with the sample of Example 1 that the lotion agent is excellent in the viscous state immediately after preparation, and that the stability of the viscous state is also excellent. In addition, from the results of the samples of Examples 10 to 15, it is confirmed that when the blending ratio of dextrin D increases, the viscosity state decreases 24 hours after the preparation. On the other hand, it can be seen that the stability of the viscous state is further improved when the blending ratio of the dextrin in Examples 1 to 9 is lower.

The samples of Examples 1 to 19 are as follows.
The state of rinsing with warm water (37 ° C.) after use was all good, and no residue was confirmed.

(Examples 20 to 27) 50 g of powder of locust bee gum A, carrageenan B or xanthan gum C
Dextrin D powder 150g and 200g respectively
The mixture was uniformly mixed, and a predetermined amount of each of these mixtures was added to warm water at 40 ° C., and the mixture was stirred with a spatula to prepare 200 ml of lotions (Examples 20 to 28).

Each of these lotion preparations was used as a sample, immediately after preparation, and stored in a beaker at room temperature (25 ° C.).
With the sample left standing, the pH value was measured 24 hours after the preparation and 48 hours after the preparation, and the viscosity was tested and confirmed. The results are shown in Table 2. In addition,
The test method for the viscous state and the criterion for the test result are the same as those in Examples 1 to 19.

[0030]

[Table 2]

From the results shown in Table 2, for each sample,
It can be seen that the PH value gradually decreases over time, and the PH value after the decrease reaches the acidic side. It can also be seen that as the pH value of the sample becomes more acidic, the viscosity decreases in each case. Such a tendency for the PH value to decrease is observed in Examples 20, 22, 24 and 26 and Examples 21 and 2.
In comparison with 3, 25, and 27, it can be seen that the smaller the blending ratio of dextrin is, the smaller the blending ratio of dextrin is, and the more stable the viscous state is. In addition, for the samples of Examples 20 to 27, the state of rinsing with warm water (37 ° C.) after use was all good, and no residue was confirmed.

(Embodiments 28 to 31) Embodiment 2 described above
For each of the samples 0, 21, 24 and 25,
By adding and mixing a 0.5% aqueous solution of sodium hydroxide, their pH values were adjusted to PH 8.0,
These were used as samples (Examples 28 to 31).

With respect to these samples, PH values are measured immediately after preparation and in a state in which they are stored in a beaker and left at room temperature (25 ° C.), 24 hours after preparation and 48 hours after preparation. At the same time, the viscous state was tested and confirmed, and the results are shown in Table 3. The test method for the viscous state and the standard of the test result are the same as those in Examples 1 to 19.

[0034]

[Table 3]

From the results shown in Table 3, Examples 28 to 31 were obtained.
Regarding any of the samples, although a decrease in the PH value over time is observed, 48 hours after the adjustment,
In any case, it is more than neutral alkaline, and moreover,
In each case, it can be seen that the initial viscous state is stably maintained. In particular, in the case of the samples of Examples 29, 30, and 31, when the PH value of each of the samples was increased in advance in comparison with Examples 21, 24, and 25 described above, It can be seen that the stability is improved. In addition, as for the samples of Examples 28 to 31, the state of rinsing with warm water (37 ° C) after use was all good, and no residue was confirmed.

[0036]

As described above, since the present invention is constituted, the following effects are exhibited. First, the viscous lotion agent according to the present invention, since locust bean gum, one or more selected from carrageenan and xanthan gum, dextrin, and water as components,
A lotion having a suitable viscosity can be obtained as a lotion for massage or ultrasonic echo.

In addition, this viscous state is obtained as a substance that is required to be used as a lotion and that maintains stability for at least 3 hours after preparation. Furthermore, since a relatively large amount of dextrin is contained as a component, the dextrin can be easily washed away with room temperature water or warm water with little residue left on the skin surface. Accordingly, skin roughness due to the decay of the residue hardly occurs, and all of these components are food additives, so that they can be used safely.

In particular, a composition in which the blending ratio of locust bean gum or the like and dextrin is in the range of 1 to 2 or more and less than 4 in terms of parts by weight, and further, the PH value of the preparation is 7.
According to the configuration adjusted to be in the range of 5 or more and 8.0 or less, the effect of maintaining the stability of the above-mentioned viscous state for a longer time is exhibited.
