Description

Technical Field

[0001] The present invention relates to an aqueous cosmetic. Background Art

[0002] Aqueous cosmetics such as lotions are widely used for penetrating into the skin and imparting a moisturizing feel. Generally, in aqueous cosmetics, lipophilic components are solubilized and formulated, which is preferred because it allows simultaneous application of lipophilic components and hydrophilic components, and the product is transparent and excellent in aesthetic appearance (Patent Document 1, etc.).

[0003] D-pantothenyl alcohol is an alcohol-type derivative of pantothenic acid, and is a substance that is converted into vitamin B5 (pantothenic acid) in the body. Since D-pantothenyl alcohol has useful effects such as an effect of improving rough skin and a whitening effect, it has been conventionally formulated into external skin preparations (Patent Documents 2 and 3).

[0005] Generally, in order to achieve a sense of penetration into the skin in aqueous cosmetics, the formulation needs to have a certain viscosity, and water-soluble polymers such as carboxyvinyl polymers are usually incorporated. However, the present inventors have found that when D-pantothenyl alcohol is incorporated into aqueous cosmetics, the thickening effect of the water-soluble polymer is insufficient, and viscosity cannot be maintained. Increasing the content of water-soluble polymers can increase viscosity, but this results in poor adherence to the skin, a film-like feeling after drying, and other undesirable aspects of use. In this context, the present invention aims to provide a technology for an aqueous cosmetic composition containing D-pantothenyl alcohol that improves penetration and reduces the likelihood of a film-like feeling after application. [Means for solving the problem]

[0006] The inventors of the present invention conducted intensive research to solve the above problems and found that the above problems can be solved by combining an anionic polymer and locust bean gum in an aqueous cosmetic composition containing D-pantothenyl alcohol, thereby completing the present invention.

[0007] In other words, the present invention is as follows: [1] An aqueous cosmetic containing D-pantothenyl alcohol, an anionic polymer, and locust bean gum. [2] The aqueous cosmetic composition according to [1], wherein the anionic polymer is a carboxyvinyl polymer and / or an acrylates / alkyl acrylate (C10-30) crosspolymer. [3] The aqueous cosmetic composition according to [2], wherein the anionic polymer is a carboxyvinyl polymer. [4] The aqueous cosmetic according to any one of [1] to [3], wherein the total content of D-pantothenyl alcohol is 0.1 to 5.0% by weight of the total cosmetic. [5] The aqueous cosmetic according to any one of [1] to [4], wherein the total content of the locust bean gum is 0.001 to 0.02% by weight of the total cosmetic. [6] The aqueous cosmetic composition according to any one of [1] to [5], wherein the total content of the anionic polymer is 0.01 to 0.25% by weight of the entire cosmetic composition. [7] The aqueous cosmetic composition according to any one of [1] to [6], wherein the weight ratio of the total content of the anionic polymer to the content of the locust bean gum is 1:10 to 100:1. [8] The aqueous cosmetic composition according to any one of [1] to [7], wherein the total content of the anionic polymer and the locust bean gum is 0.02 to 0.25% by weight of the entire cosmetic composition. [9] Viscosity at 25°C is 3000-6000 m A water-based cosmetic product, Pa·s, as described in any of [1] to [9]. [Effects of the Invention]

[0008] The present invention provides an aqueous cosmetic composition that exhibits excellent penetration during application and is less likely to leave a film-like feeling after application. In this specification, "penetration" refers to the fact that when the cosmetic composition is applied to the skin, it settles into the skin without feeling sticky and blends well with the skin. [Modes for carrying out the invention]

[0009] The aqueous cosmetic composition of the present invention contains D-pantothenyl alcohol, an anionic polymer, and locust bean gum.

[0010] D-Panthenyl alcohol is a compound represented by the following structural formula (1). [ka]

[0011] D-pantothenyl alcohol is used as an ingredient in topical skin preparations such as cosmetics, and is readily available; commercially available products can be used as appropriate.

[0012] The content of D-pantothenyl alcohol in the cosmetic of the present invention is preferably 0.1% by weight or more, more preferably 0.5% by weight or more, and still more preferably 1.0% by weight or more, based on the total weight of the cosmetic. Further, it is preferably 5% by weight or less, more preferably 3% by weight or less, and still more preferably 2% by weight or less. In addition, the content may be within a range of any combination of these upper and lower limits that does not conflict with each other. Inclusion of D-pantothenyl alcohol within this range facilitates the exertion of desired effects exhibited by D-pantothenyl alcohol, such as whitening (suppression of pigment deposition) and anti-wrinkle effects.

[0013] The anionic polymer is not particularly limited, and examples thereof include carboxyvinyl polymer, alkyl-modified carboxyvinyl polymer, alginic acid or a salt thereof, acrylic acid-based water-soluble polymer, and any one or a combination of two or more of these can be used. Preferred examples of the acrylic acid-based water-soluble polymer include non-crosslinked acrylic acid-based polymers, and optionally crosslinked acrylic acid-based copolymers. Preferred examples of the non-crosslinked acrylic acid-based polymer include sodium polyacrylate, polyethyl acrylate, and polyacrylamide; and a preferred example of the optionally crosslinked acrylic acid-based copolymer is (acrylates / alkyl (C10-30) acrylate) crosspolymer. As the anionic polymer in the cosmetic of the present invention, it is particularly preferable to use carboxyvinyl polymer and / or (acrylates / alkyl (C10-30) acrylate) crosspoly mer.

[0014] Anionic polymers are used as raw materials for external skin preparations such as cosmetics, are not difficult to obtain, and commercially available products can be appropriately used. The size of the anionic polymer is not particularly limited as long as it is of a size commonly used in cosmetics.

[0015] In the cosmetic of the present invention, the content of the anionic polymer is preferably 0.01% by weight or more, more preferably 0.05% by weight or more, and even more preferably 0.1% by weight or more, relative to the total mass of the cosmetic. Further, the content is preferably 0.25% by weight or less, more preferably 0.2% by weight or less, even more preferably 0.15% by weight or less, and particularly preferably 0.12% by weight or less. The content may be within a range of any non-contradictory combination of these upper limits and lower limits. Incorporation within this range facilitates improving the penetration feeling of the cosmetic and also facilitates suppressing the film-forming feeling.

[0016] Locust bean gum is obtained from the seeds of the carob tree (Celatonia siliqua Linne, also called locust bean), which is a leguminous plant, and is a polysaccharide. The main chain is composed of mannose and the side chains are composed of galactose, wherein galactose and mannose are randomly contained at a ratio of 1:4. The molecular weight of locust bean gum may be of a level commonly used in cosmetics, for example, may be about tens of thousands to hundreds of thousands.

[0017] Locust bean gum is used as a raw material for external preparations for skin such as cosmetics, is not difficult to obtain, and commercially available products can be appropriately used.

[0018] In the cosmetic of the present invention, the content of locust bean gum is preferably 0.001% by weight or more, more preferably 0.002% by weight or more, and even more preferably 0.004% by weight or more, relative to the total mass of the cosmetic. Further, the content is preferably 0.02% by weight or less, more preferably 0.015% by weight or less, and even more preferably 0.01% by weight or less. The content may be within a range of any non-contradictory combination of these upper limits and lower limits. Incorporation within this range facilitates improving the penetration feeling of the cosmetic and also facilitates suppressing the film-forming feeling.

[0019] In the cosmetic composition of the present invention, the weight ratio of the total content of anionic polymer to the content of locust bean gum is preferably 1:10 to 100:1, more preferably 1:5 to 50:1, and even more preferably 20:1 to 400:1. Furthermore, in the cosmetic composition of the present invention, the total content of the anionic polymer and the locust bean gum is preferably 0.02% by weight or more, more preferably 0.05% by weight or more, and even more preferably 0.1% by weight or more, relative to the total content of the cosmetic composition. It is also preferably 0.25% by weight or less, more preferably 0.2% by weight or less, and even more preferably 0.12% by weight or less. Furthermore, it may be within a range of a non-contradictory combination of these upper and lower limits. By combining and incorporating these elements within this range, the penetration of the cosmetic product becomes easier to improve, and the feeling of a film on the skin becomes easier to suppress.

[0020] The aqueous cosmetic composition of the present invention preferably has a viscosity of 3000 to 6000 at 20°C as measured by a B-type viscometer. m Pa·s, comfort 3500~5000 m Pa·s, more preferably 3700-4500 m It is Pa·s. This viscosity range makes it easy to achieve a good penetration feeling when applied to the skin. The measurements using a Type B viscometer are based on a VDA2 vismetron viscometer (manufactured by Shibaura Semtec Co., Ltd.) at 20°C, using rotor No. 1, at a rotation speed of 3 rpm, and performed for 1 minute.

[Examples]

[0056] The present invention will be described in more detail below with reference to examples, but the present invention is not limited to the following examples unless it exceeds the gist of the invention.

[0057] <Example Test> A water-based cosmetic was prepared by mixing the formulation ingredients listed in Table 1.

[0058] [Table 1]

[0059] <Viscosity> The viscosity of each obtained aqueous cosmetic was measured at 20°C using a B-type viscometer, a VDA2 bismetron viscometer (manufactured by Shibaura Semtec Co., Ltd.), with rotor No. 1, at a rotation speed of 3 rpm and for 1 minute.

[0060] <Penetration feeling> When the resulting aqueous cosmetic was applied to the skin, experienced evaluators assessed whether it had a certain viscosity initially and whether it subsequently settled without becoming sticky. ◎: Excellent penetration. ○: Good absorption. △: Does not penetrate well ×: Does not penetrate well

[0061] <Film feeling> After applying the resulting aqueous cosmetic to the skin and allowing it to dry, experienced evaluators assessed whether or not there was a feeling of tightness or film-like sensation on the skin. ◎: Very good, with no film-like feeling. ○: Excellent, with almost no film-like feeling. △: Has a slightly film-like feel. ×: It feels like it has a coating and is unpleasant.

[0062] The results are shown in Table 1. In the aqueous cosmetic compositions of Examples 1 to 6, both penetration and film-forming properties were good. In Comparative Example 1, an aqueous cosmetic composition that did not contain locust bean gum, viscosity decreased, impairing penetration and resulting in a film-forming property after application. Furthermore, in Comparative Example 2, an aqueous cosmetic composition that did not contain locust bean gum but had its viscosity increased with xanthan gum, penetration was insufficient. Therefore, it was found that in order to obtain good penetration in aqueous cosmetic compositions containing D-pantothenyl alcohol, simply increasing viscosity is insufficient; the inclusion of locust bean gum is necessary. [Industrial applicability]

[0063] The present invention provides an aqueous cosmetic composition that exhibits excellent penetration during application and is less likely to leave a film-like feeling after application. Such a cosmetic composition, along with the effects of D-pantothenyl alcohol, meets the needs of consumers seeking a superior user experience and is therefore highly useful in industry.
