Definitions
- the present invention relates to an oil-in-water emulsified cosmetic, and more specifically, an oil-in-water emulsified cosmetic that can bring elasticity and firmness to the application site of the cosmetic without the addition of a drug or the addition of a powder or a film agent. It is about the fee.
- vitamin A and its derivatives are known as drugs effective for these.
- Patent Document 1 describes that skin penetration of vitamin A ester is improved by blending casein. However, it is difficult to mix these ingredients in cosmetics and maintain them stably in an effective state for the skin.
- Patent Document 2 describes a technique for preventing and stabilizing the hydrolysis of vitamin A ester by blending an antioxidant and a specific amount of a nonionic surfactant. Since the addition of an emulsifier, which is essential, is limited, a desirable cosmetic is not always obtained in terms of viscosity and feel. In addition, in order to clarify the effects of the above-mentioned drugs, continuous application is necessary, and also in the sense of promoting the continuation, it is possible to feel a firmness and recovery of elasticity in a relatively short time after application, It is an important element for cosmetics.
- Ingredients that can impart a sense of elasticity and elasticity in a short period of time include, for example, polyvinyl alcohol, sodium alginate, mucopolysaccharides and collagen, eggshell proteins, and their decomposition products, film-forming components such as acrylic resins, Spherical and other powders (Patent Document 3), cross-linked methylpolysiloxane (Patent Document 4), and the like have been used.
- blended with the oil-based base (patent document 5) containing the ester of dimer acid and / or dimer diol excellent in water retention in combination with the film forming component and the moisturizing component as described above are applied to the skin. It is also known that a good gloss and firmness can be given (Patent Document 6).
- JP-A-8-245366 Japanese Patent No. 3634139 Japanese Patent Laid-Open No. 5-933 JP 9-315936 A JP 2004-256515 A JP 2007-269723 A
- the present invention has been made in order to solve the conventional problems as described above, and has elasticity and firmness of the skin regardless of the presence or absence of a drug such as vitamin A, a film-forming component or powder.
- An object of the present invention is to provide an oil-in-water emulsified cosmetic obtained and having good stability.
- a composition prepared with a higher alcohol, a polyoxyethylene alkyl ether, and a glycerin monoalkyl ether brings about elasticity and firmness of the skin. It has been found that there is an effect, and further, it has been found that long-term stability is maintained by making the ratio specific.
- the present invention (A) one or more selected from higher alcohols having 14 to 22 carbon atoms; (B) one or more selected from hydrophilic polyoxyethylene alkyl ethers; (C) one or more selected from glycerin monoalkyl ethers; Containing
