Description

  The present invention relates to a water-in-oil type cosmetic for cosmetics having excellent adhesion and friction resistance, good curl-up and volume-up effects, and excellent storage stability.

  Traditionally, eyelash cosmetics are applied to eyelashes for the purpose of making the eyelashes stand out, such as curl-up and volume-up effects, and are easily affected by sweat and tears due to the characteristics of the application site. receive. For this reason, sweat resistance, water resistance, and the like have been indispensable functions. In order to obtain these functions, we have developed oily or water-in-oil mascara and put it on the market more. For oil-in-water types, these functions have been imparted by blending film-forming resins. As described above, vaginal cosmetics of various dosage forms have been developed at present. In particular, water-in-oil type vaginal cosmetics are generally more resistant to sweat and water than oil-in-water types, have a smoother feeling than oil-based types, and have excellent cosmetic effects such as curling up and volume up. Since it has the advantage of being easy to release, it tends to be preferred by consumers, and many products are on the market.

  Furthermore, in recent years, in addition to the basic functions described above, a cosmetic coating film has an adhesive function that allows a sufficient amount of cosmetic liquid to adhere well to the eyelashes and generate a volume in one application, and an external frictional force. There is a strong demand from consumers for vaginal cosmetics that also have a friction-resistant function to prevent peeling and color transfer to the skin and clothing. In order to satisfy these needs, various compounding studies have been made, and attempts have been made to improve adhesion and friction resistance by increasing the compounding amount of waxes having appropriate properties.

  However, there is a problem that if the amount of the wax is increased, the amount of the wax is likely to become lumpy at the time of application, and the amount of the wax needs to be limited. In addition, as described above, water-in-oil vaginal cosmetics have the advantages of sweat resistance, water resistance, smooth use feeling, and excellent cosmetic effects such as curling up and volume up. There was a drawback of poor stability. Originally, the emulsion has the property of being weak against external frictional resistance. Furthermore, waxes and the like that are generally blended in cosmetics for vaginal skin have a problem in that they have low frictional resistance due to their weak bonding force, and the cosmetic film is easily peeled off after application.

  For this reason, there exist some which provided migration resistance by mix | blending a polysaccharide resin and the film formation agent other than that, for example (refer patent document 1). Several inventions have been reported that attempt to reinforce the decorative film by blending various resins in this way. However, in these inventions, the film strength of the decorative film is not always sufficient, and it has been difficult to keep the decorative film uniform for a long time. Moreover, in order to produce the effect of strengthening the film, it has been necessary to cause dullness during coating or sacrifice other functions such as curl-up force, friction resistance and adhesion.

  In addition, efforts have been made to incorporate organically modified viscosity minerals such as dimethyl distearyl ammonium hectolite and dimethyl distearyl ammonium bentonite for the purpose of improving the storage stability of water-in-oil cosmetics (see Patent Document 2). ). However, in these inventions, it cannot be said that the storage stability is sufficient, the friction resistance is very poor, and peeling of the decorative coating frequently occurs.

Special table 2003-508472 gazette Special table 2001-506608 gazette

  Under such circumstances, the object of the present invention is to provide a makeup-in-the-water cocoon that makes the eyes stand out, such as curl-up and volume-up effect, excellent adhesion to eyelashes and friction resistance, and excellent storage stability. In providing cosmetics.

  Therefore, as a result of diligent research to solve the above problems, the present inventors have formulated curl-up and volume-up effects by blending water, a nonionic surfactant, an eicosene vinylpyrrolidone copolymer, and a dextrin fatty acid ester. As a result, the present inventors have found that a cosmetic for water-in-oil type with excellent makeup effect, eyelash adhesion, friction resistance, and storage stability can be obtained. It was.

That is, the present invention includes the following components (A), (B), (C) and (D):

(B) Nonionic surfactant 0.1-5 mass%
(C) Eicosene / vinylpyrrolidone copolymer 0.1 to 5% by mass
(D) Dextrin fatty acid ester 0.1-10 mass%
A water-in-oil cosmetic for cosmetics, characterized by containing

  By applying the above-mentioned formulation, the vaginal cosmetic of the present invention has the advantages of a water-in-oil vaginal cosmetic that has a smooth feel during application and is water and sweat resistant. However, it was possible to exhibit moderate tackiness, and it was possible to attach a large amount of cosmetic liquid by a single application. In addition, the network between the water layer and the oil layer, which originally caused the peeling of the decorative film, and the network between the various components such as waxes and resins in the oil layer are effective. It has become possible to dramatically improve the friction resistance of the decorative coating by adhering to the surface.

As is clear from the results in Table 1, the mascara of Examples 1 to 3 which are the products of the present invention are compared with the mascara of Comparative Examples 1 to 5, and the cosmetic effect and friction resistance that make the eyes stand out, and the durability thereof, It can be seen that it has excellent properties in all aspects of adhesion, feeling of use, and storage stability. On the other hand, the sample of Comparative Example 1 in which the blending amount of the wax was less than 10% had a poor cosmetic effect and a poor usability. The samples of Comparative Examples 1 and 2, in which no eicosene / vinylpyrrolidone copolymer was blended, had poor adhesion and did not provide satisfactory friction resistance. Moreover, the sample of the comparative example 2 whose compounding quantity of water is less than 1% had a bad usability, and the sample of the comparative examples 3 and 4 which does not contain dextrin fatty acid ester had bad friction resistance and its durability. Further, the sample of Comparative Example 3 in which no nonionic surfactant was blended was remarkably poor in storage stability. Moreover, the comparative example 5 which does not contain a nonionic surfactant was inferior in all aspects. From the above, satisfactory results were not obtained with the mascaras of Comparative Examples 1 to 5.

  The water-in-oil type cosmetic for cosmetics of the present invention is water and sweat resistant and has a good feeling of use, and is excellent in cosmetic effect such as volume up and curl up, adhesion and friction resistance. Can meet the various needs of consumers.
