Description

  The present invention relates to an effervescent cosmetic used by generating a carbon dioxide gas by mixing a plurality of compositions.

Conventionally, the effect of carbon dioxide on a living body has attracted attention. Carbon dioxide expands blood vessels through percutaneous absorption, promotes blood circulation, binds to hemoglobin, liberates oxygen, and promotes cell activity (cell activity due to Bohr effect).
In recent years, various cosmetics using carbon dioxide gas have been put on the market and are gaining popularity. Specifically, it has been proposed that a plurality of compositions are mixed at the time of use, carbon dioxide is generated by a chemical reaction, and applied to the skin as a foamy cosmetic.
However, conventional foamable cosmetics are: 1) Powder or granules of at least one of a composition containing carbonate and a composition containing acid and mixed with a liquid base at the time of use (Patent Document 1, etc.) 2) Carbon dioxide gas was previously put in a pressure-accumulation type aerosol container, etc., discharged during use, and mixed with other cosmetic bases.

These results indicate that the above-described effect can be obtained even when a salt other than sodium hydrogen carbonate, that is, various salts such as potassium hydrogen carbonate and sodium carbonate are coated with a coating agent.

As shown in Table 6, the facial cleanser of Example 9 comprising potassium bicarbonate coated with (acrylates / VA) copolymer and sodium carbonate coated with gelatin was compared to the shampoos of Examples 7 and 8. Excellent foam retention and cleaning power.
This result is similar to the result shown in Table 2 in that it includes two or more groups of hydrogen carbonates and / or carbonates coated with different coating agents, thereby improving foam retention and make-up removal effect (detergency). It shows that it can be improved further.
Combined with the results of Test Example 1 and Test Example 2, the effect of including two or more groups of bicarbonates and / or carbonates coated with different coatings is that when using various coatings. It also shows that it can be obtained.

<Test Example 4> Foam massage washing pack A foam massage washing pack having the formulation shown in Table 7 was prepared by the following method. That is, for tank A, (4) and (7) are previously dissolved in a part of (1), and (2), (3), (5), (6) and (8) are dissolved in the remaining (1). To (12) and (4) and (7) dissolved in advance were added and mixed in order, and the mixture was uniformly dissolved. As the coated sodium hydrogen carbonate of (11), the one previously coated with ethyl cellulose by the above-described method was used.
For tank B, (25) was previously dissolved in (22), and (13) to (17) were added thereto and mixed with stirring. On the other hand, (18) to (21), (23) and (24) were mixed and made uniform. B tank component was prepared by adding the latter liquid mixture to the former liquid mixture, emulsifying and homogenizing.

  A pouch container (packaging) separated into two tanks was filled separately with the A tank component and the B tank component. In the same manner as in Test Example 1, the foaming, foam retention, detergency, and uniform dispersibility when equal amounts of the A tank component and B tank component were mixed were evaluated. The results are shown in Table 8.

  As shown in Table 8, the cosmetic of Example 10 showed excellent foaming, foam retention, detergency, and uniform dispersibility of the coated sodium hydrogen carbonate.

<Test Example 5> Cleansing Cleansing of the formulation shown in Table 9 was produced by the following method. That is, for tank A, (5) and (6) are preliminarily dissolved in part of (1), (2) to (4), (7) and (8), and preliminarily dissolved in the remaining (1). (5) and (6) were sequentially added and mixed, and the mixture was uniformly dissolved. For (8), using the filler of (8-2) to (8-4) and (8-6), sodium bicarbonate (8-1) coated with ethyl cellulose by the above-mentioned method is used. It was.
About B tank, it prepared by mixing (9)-(17) uniformly.

Each tank of the two tank integrated tube was filled with the tank A component and the tank B component, respectively. Subsequently, 5 estheticians (special panel) discharged the usage amount of the A tank component and B tank component from the tube and mixed them for a certain period of time using fingers. Evaluated. The foam quality and ease of washing were also evaluated according to the following criteria. The average of the evaluations of five people is calculated and shown in Table 10.
Moreover, about foam retention, the time until the height of the said bubble became 1/3 was measured immediately after forming the bubble of 2 cm height. The results are shown in Table 10.

<Evaluation criteria-Foam quality>
3: Fine foam with creaminess and elasticity 2: Fine foam with creaminess but slightly lacking in elasticity 1: Coarse foam with no creaminess and lack of elasticity 0: Coarse with no creaminess and elasticity Bubbles

<Evaluation criteria-Ease of washing>
3: Easy to wash away (no residual feeling on the skin)
2: Feels somewhat difficult to wash away (feels a little residual on the skin)
1: Difficult to wash away (feels remaining on the skin)
0: Cannot be washed away (remains on skin)

As shown in Table 10, Example 11 containing saponin is superior to Example 12 not containing saponin in foaming, foam quality, and makeup removing effect (detergency).
This result has shown that the cosmetics of this invention are excellent in foaming, foam quality, and make-up removal effect (detergency) by containing saponin.
In addition, as shown in Table 10, Example 12 containing coated sodium hydrogen carbonate, compared to Example 14 not containing this, foaming, foam retention and make-off effect (detergency), foam quality and ease of washing away Excellent.
This result indicates that inclusion of bicarbonate and / or carbonate coated with a coating improves not only foaming, foam retention and make-up effect (detergency), but also foam quality and ease of washing. ing.

  The present invention can be applied to cosmetics.
