Description

Technical Field

[0001] This technology relates to multi-layer cosmetics.

Background Art

[0002] Conventionally, there has been known a multi-layer cosmetic that is separated into multiple layers before use and is shaken and mixed at the time of use and then applied to the skin or hair. This multi-layer cosmetic becomes a uniform emulsion or powder dispersion state by shaking, and when left standing, the dispersed oil or powder separates and becomes multi-layered again. In recent years, it has been widely accepted by consumers regarding the aesthetic appearance of this multi-layer cosmetic, and technologies for imparting and maintaining the aesthetic appearance have been studied. For example, Patent Document 1 discloses a technology for providing a multi-layer cosmetic that contains a polyoxyethylene alkyl ether and a polyoxyethylene hydrogenated castor oil having a specific HLB, an oil agent and a polysaccharide that are liquid at 25°C, and maintains a specific pH, and is excellent in stability over time and usability.

[0003] Furthermore, in recent years, technologies for blending polymer compounds such as resins to enhance the functionality of multi-layer cosmetics and meet the needs of consumers have also been studied. For example, Patent Document 2 discloses a technology for a makeup protective cosmetic that is used by spraying it from above makeup.

Summary of the Invention

Problems to be Solved by the Invention

[0005] [[ID=四十二]] However, it was not widely known that maintaining aesthetic appearance in multilayer cosmetics can lead to unpleasant odors derived from the base, such as characteristic oily odors, acidic odors, and organic solvent odors, and that this tends to exacerbate odor changes over time. This concern is particularly strong when resins are included to enhance functionality, and there was insufficient knowledge regarding which components are suitable for improving odor changes. [Means for solving the problem]

[0006] Therefore, the inventor focused on concerns about odor changes originating from multilayer cosmetics containing resins and conducted diligent research. As a result, they discovered a new fragrance component that, when blended with multilayer cosmetics, exhibits excellent masking and matching effects against odor changes originating from multilayer cosmetics, as well as superior fragrance release.

[0007] In other words, the present invention is as described below. [1] The following components (A) to (D); (A) Resin (B) Liquid oil at 25℃ (C)Water A fragrance composition containing at least two fragrance components whose (D)(d1)XlogP is 4 or less. It is a multi-layered cosmetic containing [ingredient]. [2] The fragrance composition of component (D) is a multilayer cosmetic composition according to [1], further containing one or more fragrance components in which component (d2)XlogP is greater than 4. [3] The multilayer cosmetic composition according to [2], wherein the mass ratio of component (d1) to component (d2) (d1) / (d2) is 3 or more. [4] A multilayer cosmetic composition according to [1] or [2], wherein the mass ratio (D) / (C) of component (D) to component (C) is 0.000005 or more. [Effects of the Invention]

[0008] The multilayer cosmetic composition of the present invention (hereinafter also simply referred to as "cosmetic composition") contains a resin and can improve the odor exacerbated by the multilayer structure. Effects of improving the odor originating from the multilayer cosmetic composition include, for example, masking effect, matching effect, and fragrance enhancement, and the present invention excels in these effects. Furthermore, the present invention also exhibits excellent layer separation properties and film formation speed as a multilayer cosmetic composition. It should be noted that the effects described herein are not necessarily limited, and any of the effects described herein may be used. [Modes for carrying out the invention]

[0009] The following describes preferred embodiments for carrying out the present invention. The embodiments described below are merely examples of representative embodiments of the present invention and should not be interpreted as narrowing the scope of the invention. Furthermore, unless otherwise specified, percentages in this specification are expressed in terms of mass. The upper limit (less than or equal to) and lower limit (greater than or equal to) of each numerical range (~) can be arbitrarily combined as desired. In this specification, "X~Y" indicating a range includes X and Y, meaning "X or greater and Y or less."

[0010] In the present invention, "unpleasant odor" refers to an unpleasant odor (hereinafter sometimes abbreviated as "unpleasant odor") that originates from a multilayer cosmetic and develops over time, and is particularly exacerbated by the inclusion of resin. In the present invention, the unpleasant odor originating from a multilayer cosmetic is not particularly limited, but is usually an oily odor. Furthermore, from the viewpoint of being able to better experience the masking effect, matching effect, and fragrance development of the present invention, it is more preferable that the multilayer cosmetic be a multilayer of at least two layers including an oil layer and a water layer, and that it targets odors under high-temperature conditions where there is a high concern about odor change (for example, 50°C for one month). Here, in the present invention, the oil layer is a layer of oil-soluble components and may include a W / O emulsion. The water layer is a layer of water-soluble components and may include an O / W emulsion.

[0011] In this invention, "masking effect" refers to the effect of relatively improving an unpleasant odor by having a strong, pleasant fragrance (aroma) compete with it.

[0012] In this invention, "matching effect" refers to the effect of improving an unpleasant odor by mixing it with a fragrance (aroma, scent) that harmonizes with the unpleasant odor, incorporating the unpleasant odor as a component of a pleasant fragrance, and harmonizing the overall scent.

[0013] In this invention, "fragrance release" refers to the fragrance that can be felt immediately after spraying the cosmetic onto the skin, or the fragrance that can be felt from immediately after application until it is spread and absorbed, and refers to the effect of making the cosmetic pleasant to use.

[0014] In this invention, "improvement of unpleasant odors" means making unpleasant odors undetectable through sensory means (elimination of unpleasant odors) or mitigating unpleasant odors. Furthermore, in this invention, "odor prevention" is synonymous with "improvement of unpleasant odors" unless otherwise specified.

[0015] <Component (A) Resin> The resin used in the present invention (hereinafter also referred to as "component (A) resin" or "component (A)") includes lipophilic resins and hydrophilic resins. It is not particularly limited as long as it can be used in cosmetics or topical skin preparations, and its origin is not limited to natural resins, semi-synthetic resins, synthetic resins, etc.

[0041] <Component (D) Fragrance composition> Component (D) used in the present invention is a fragrance composition, and component (D) contains at least two fragrance components of component (d1) with an XlogP of 4 or less. LogP is a partition coefficient that serves as an indicator of the hydrophobicity of a chemical substance, and because it is difficult to obtain an actual measured value, there are various prediction methods such as CLogP, ALogP, and SLogP. Among these prediction methods, XlogP is a prediction method that decomposes molecules into individual atoms, considers the contribution of each, and corrects for this. In this application, XlogP was examined using values ​​listed in PubChem (https: / / pubchem.ncbi.nlm.nih.gov / ).

[0099] <Evaluation method: (c) Aroma> Six fragrance experts evaluated each sample after storing it in a 50°C constant temperature bath for one month and then allowing it to cool to room temperature. They then assessed the fragrance (the scent perceived immediately after spraying the multi-layered cosmetic). A five-point scale was assigned according to the evaluation criteria below, and the average score of all evaluators was calculated. The results of the evaluations, based on the judgments below, are shown in Tables 1-4.

[0100] [5-point rating scale] (Rating) : (Evaluation) 5 points: Excellent fragrance development. 4 points: Good fragrance release 3 points: The fragrance is slightly better. 2 points: The fragrance is not very strong. 1 point: The fragrance is very poor.
