Description

  The present invention relates to an emulsified composition.

  Conventionally, cosmetics with high skin moisture retention have been demanded. In order to keep the skin moisturizing property (hereinafter, also simply referred to as “moisturizing”), for example, a technique using petrolatum having a high occlusive property has been proposed (for example, see Patent Documents 1 and 2). Moreover, the technique of moisturizing skin using low molecular weight betaine and plant-derived moisturizing ingredients such as aloe has been proposed (see, for example, Patent Document 3).

  In the techniques of Patent Documents 1 and 2, since the amount of petrolatum is large, the stickiness when applied to the skin (hereinafter, also simply referred to as “stickiness”) is strong, and the elongation when applied to the skin (hereinafter simply “ Also called “elongation”) was not enough. Moreover, in the technique of patent document 3, although the alginic acid of polysaccharide is used for the purpose of improving moisture retention, the stickiness to the skin is strong, and the moisture retention is not sufficient when stickiness is suppressed. Therefore, an emulsion composition having little stickiness, good elongation and high moisture retention has been desired. In addition to moisture retention, an emulsified composition capable of imparting tension to the skin has also been desired. Such a technique is desired not only for cosmetics but also for pharmaceuticals and quasi drugs containing an emulsified composition.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the following means can be employed.

If this emulsified composition is used, it is possible to provide cosmetics, pharmaceuticals, quasi-drugs and the like having good elongation and high moisture retention.

(2) The emulsified composition, wherein (A) the semisolid oil at room temperature is contained in an amount of 5 to 7% by mass relative to the total amount of the emulsified composition. If it does in this way, the emulsification composition which does not have a sticky feeling (good sticky feeling) can be provided.

(3) The emulsified composition, wherein the (B) betaines are contained in an amount of 2 to 4% by mass relative to the total amount of the emulsified composition. Even if it does in this way, the emulsification composition which does not have a sticky feeling (good sticky feeling) can be provided.

(4) The emulsified composition, wherein the (C) dimethylsilanol / hyaluronic acid condensate is contained in an amount of 0.01 to 1% by mass relative to the total amount of the emulsified composition. If it does in this way, a moisturizing feeling (moist feeling) can be improved, and also a sticky feeling can be suppressed.

(5) The emulsion composition, further comprising (D) collagens. If it does in this way, tension can be given to skin and a feeling of firmness can be improved.

  Note that the present invention can be realized in various modes. For example, it can be realized in various forms such as cosmetics, pharmaceuticals, and quasi drugs containing an emulsified composition.

  As shown in Tables 1 to 4, although the creams of Examples 1 to 19 all have a difference in content, (A) a semi-solid oil at room temperature (in Tables 1 to 4, simply “semi-solid Oil ”) as petrolatum (component 1), dipentaerythritol fatty acid ester (component 2), (adipic acid, 2-ethylhexanoic acid, stearic acid) glyceryl oligoester (component 3) or hydrogenated dimer dilinoleic acid Contains castor oil (component 4). Further, (B) contains trimethylglycine (component 5) as betaines, and further contains (C) a dimethylsilanol / hyaluronic acid condensate (component 6). Examples 17 to 19 further contain water-soluble collagen (component 7), hydrolyzed collagen (component 8), and collagen (component 9) as (D) collagens. The creams of Examples 1 to 19 were excellent (◎ or ◯) in all the items of “base elongation”, “stickiness”, “familiarity”, “moist”, and “feel”.

  Examples 1 to 8 will be described based on Table 1 in comparison with Comparative Example 1. As shown in Table 1, the creams of Examples 1-5 are (A) petrolatum (component 1) as semi-solid oil, (B) trimethylglycine (component 5) as betaines, (C) dimethylsilanol / hyaluronic acid Condensation liquid (component 6) is contained. In the creams of Examples 6 to 8, instead of petrolatum (component 1) in the cream of Example 3, dipentaerythritol fatty acid ester (component 2) and (adipic acid, 2-ethylhexanoic acid, stearic acid), respectively Glyceryl oligoester (component 3) and dimerlinoleic acid hydrogenated castor oil (component 4) are contained as (A) semi-solid oil. On the other hand, the cream of Comparative Example 1 does not contain (A) semi-solid oil, and other components are the same as those in Examples 1-8.

  Examples 1 to 5 will be described based on Table 1 in comparison with Comparative Example 1. As shown in Table 1, the creams of Examples 1 to 5 contain petrolatum (component 1) as (A) semi-solid oil, (B) trimethylglycine (component 5) as betaines, and (C) dimethylsilanol. -Contains a hyaluronic acid condensate (component 6). On the other hand, the cream of Comparative Example 1 does not contain petrolatum (component 1) as (A) semi-solid oil, and the other components are the same as in Examples 1-5.

  The cream of Comparative Example 1 was not good in “base elongation” and “moist feeling”. On the other hand, in the creams of Examples 1 to 5, “base elongation” was higher than that of Comparative Example 1. Furthermore, Examples 1 to 5 were superior to Comparative Example 1 in “moist feeling”. This is considered because (A) petrolatum (component 1) as a semi-solid oil has a high occlusion property, so that moisture in the skin can be prevented from drying. Since Examples 1-5 are the composition which added petrolatum (component 1) as semi-solid oil (A) to comparative example 1, (A) By petrolatum (component 1) as semi-solid oil It can be said that “base elongation” and “moist feeling” were improved.

  Next, the content of petrolatum (component 1) as (A) semi-solid oil will be described based on Table 1. As shown in Table 1, the creams of Examples 1 to 5 contain (B) 3% by mass of trimethylglycine (component 5) as betaines, and (C) a dimethylsilanol / hyaluronic acid condensate ( It contains 0.1% by mass of component 6). (A) Petrolatum (component 1) as a semi-solid oil contains 3% by mass, 5% by mass, 6% by mass, 7% by mass, and 9% by mass, respectively. In Examples 1 to 5, “base elongation” and “moist feeling” were improved as compared with Comparative Example 1 as described above. When the evaluation of Examples 1-5 is seen, although "base elongation" and "moist feeling" improve with the increase in content of petrolatum (component 1), "stickiness" is petrolatum (component 1). It may become worse with the increase of the content of. From the above results, it contains (A) petrolatum (component 1) as semi-solid oil, (B) trimethylglycine (component 5) as betaines, (C) dimethylsilanol / hyaluronic acid condensate (component 6) In the cream to be used, the content of petrolatum (component 1) is preferably 9% by mass or less, and more preferably 5-7% by mass.

  In Examples 1-5, the cream which used petrolatum (component 1) as (A) semi-solid oil was illustrated. Next, creams (Examples 6 to 8) using components other than petrolatum (component 1) as (A) semi-solid oil will be described based on Table 1. In the creams of Examples 6 to 8, instead of petrolatum (component 1) in the cream of Example 3, dipentaerythritol fatty acid ester (component 2) and (adipic acid, 2-ethylhexanoic acid, stearic acid), respectively Glyceryl oligoester (component 3) and dimerlinoleic acid hydrogenated castor oil (component 4) are contained as (A) semi-solid oil. In the creams of Examples 6 to 8, the content of (A) semi-solid oil is 6% by mass, respectively. As described above, this content is a preferable content of petrolatum (component 1) as (A) semi-solid oil, and is the same as the content (mass%) of petrolatum (component 1) in Example 3.

  As shown in Table 1, all of the creams of Examples 6 to 8 were “base elongation”, “stickiness”, “familiarity”, “moistness”, and “harshness”. Excellent (◎ or ○). In addition, as in the case of using petroleum jelly (component 1) as the (A) semi-solid oil, “base elongation” and “moist feeling” were improved with respect to Comparative Example 1. That is, the creams of Examples 6 to 8 are similar to (A) when petrolatum (component 1) is used as a semi-solid oil (Example 3), and there is no stickiness, good elongation, and excellent moisture retention. It is a cream that can give a firm feeling. However, the cream of Example 3 using (A) petrolatum as a semi-solid oil has better base elongation than Examples 6-8, so it is preferable to use petrolatum as the (A) semi-solid oil. .

  Examples 9 to 12 will be described based on Table 2 in comparison with Comparative Example 2. As shown in Table 2, the creams of Examples 9 to 12 contain petrolatum (component 1) as (A) semi-solid oil, (B) trimethylglycine (component 5) as betaines, and (C) dimethylsilanol. -Contains a hyaluronic acid condensate (component 6). On the other hand, the cream of Comparative Example 2 does not contain trimethylglycine (component 5) as (B) betaines, and the other components are the same as in Examples 9-12.

  The cream of Comparative Example 2 did not have a “familiar feeling”. On the other hand, the creams of Examples 9 to 12 were more “familiar” than Comparative Example 2. Since Examples 9-12 are the composition which added trimethylglycine (component 5) as (B) betaines compared with comparative example 2, (B) by trimethylglycine (component 5) as betaines, It can be said that the “familiarity” has been improved. As described above, Comparative Example 2 contains (A) petrolatum (component 1) as semisolid oil and (C) dimethylsilanol / hyaluronic acid condensate (component 6), but (B) trimethylglycine as betaines. (Component 5) is not contained. Compared to Comparative Example 2, trimethylglycine (component 5) was added as (B) betaines to improve the “feel of familiarity”, resulting in “base elongation”, “stickiness”, “feel of familiarity”, “moist” Excellent creams were obtained in all items of “feel” and “feel” (Examples 9 to 12).

  Next, the content of trimethylglycine (component 5) as (B) betaines will be described based on Table 2. As shown in Table 2, the creams of Examples 9 to 12 contain 6% by mass of (A) petrolatum (component 1) as a semi-solid oil, and (C) a dimethylsilanol / hyaluronic acid condensate ( It contains 0.1% of component 6). (B) The trimethylglycine (component 5) as betaines contains 1 mass%, 2 mass%, 3 mass%, and 4 mass%, respectively. Examples 9-12 were excellent in all the evaluation items as described above. Among them, Examples 10 to 12 were more “familiar” than Example 9. On the other hand, if the amount of trimethylglycine is too large, it may become sticky (feels sticky worse). Therefore, in a cream containing (A) petrolatum (component 1) as semi-solid oil, (B) trimethylglycine (component 5) as betaines, (C) dimethylsilanol / hyaluronic acid condensate (component 6) The content of trimethylglycine (component 5) is preferably 1 to 4% by mass. Furthermore, 2-4 mass% is more preferable.

  Next, Examples 13 to 16 will be described based on Table 3.

On the other hand, the cream of Comparative Example 3 does not contain (C) dimethylsilanol / hyaluronic acid condensate (component 6), and other components are the same as in Examples 13-16.

  The cream of Comparative Example 3 was not good in “stickiness” and “familiarity”. On the other hand, the creams of Examples 13 to 16 were more “sticky” and “familiar” than Comparative Example 3. Since Examples 13-16 were the composition which added (C) dimethylsilanol and hyaluronic acid condensate (component 6) to Comparative Example 3, (C) dimethylsilanol and hyaluronic acid condensate (component 6) ) Improved the “stickiness” and “familiarity”. As described above, Comparative Example 3 contains (A) petrolatum (component 1) as a semi-solid oil and (B) trimethylglycine (component 5) as a betaine, but (C) a dimethylsilanol / hyaluronic acid condensate. (Component 6) is not contained. As a result of adding (C) dimethylsilanol / hyaluronic acid condensate (component 6) to Comparative Example 3 to improve “stickiness” and “feeling of familiarity”, “base elongation”, “stickiness”, Excellent creams were obtained in all items of “feeling of familiarity”, “moist feeling”, and “feeling of firmness” (Examples 9 to 12). Therefore, a composition containing (A) petrolatum (component 1) as a semi-solid oil, (B) trimethylglycine (component 5) as betaines, and (C) a dimethylsilanol / hyaluronic acid condensate (component 6). Is preferable.

  Next, the content of the (C) dimethylsilanol / hyaluronic acid condensate (component 6) will be described based on Table 3. As shown in Table 3, the creams of Examples 13 to 16 contain 6% by mass of (A) petrolatum (component 1) as a semi-solid oil, and (B) trimethylglycine (component 5) as betaines. ) 3% by mass. (C) Dimethylsilanol / hyaluronic acid condensate (component 6) contains 0.01% by mass, 0.05% by mass, 0.1% by mass and 1% by mass, respectively.
