Description

[Technical Field]

[0001] The present invention relates to an emulsion composition. [Background technology]

[0002] In addition to the basic function of concealing skin imperfections such as blemishes, base makeup cosmetics such as foundations are preferred for their ability to create a natural skin appearance. There is also demand for cosmetics with UV protection. To achieve this, base makeup cosmetics typically contain powders such as pigments. Emulsifier types are often used to stably incorporate these powders and to simplify application to the skin. Emulsifier types include water-in-oil emulsions, in which an oily component is present in the continuous phase, and oil-in-water emulsions, in which an aqueous component is present in the continuous phase.

[0003] In formulations containing a large amount of powder, the powder may aggregate, causing uneven application and impairing the finish of the makeup. To solve this problem, it has been proposed to use inorganic color pigments that have been treated with amino acids or inorganic extender pigments that have been hydrophobized, or to use color pigments or extender pigments that have been subjected to a specific coating treatment (Patent Document 1).

[0004] Furthermore, in the field of cosmetics, niacinamide (also known as nicotinamide) has recently been attracting attention as an ingredient that improves skin conditions that deteriorate with age, such as wrinkles and firmness, and there are examples of it being included in oil-in-water emulsion cosmetics (Patent Document 2).

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-35094 [Patent Document 2] Special Publication No. 2003-502435 Summary of the Invention [Problem to be solved by the invention]

[0006] Compositions containing powders such as pigments may feel rough when applied to the skin or may cause the applied film to become wrinkled over time. Niacinamide also imparts smoothness to the composition and improves the feel after application, but may also cause a sticky feeling when applied. In view of the above circumstances, an object of the present invention is to provide an emulsion composition that does not cause stickiness or squeaking when applied and that does not cause the applied film to wrinkle even after a long time has passed since application. [Means for solving the problem]

[0007] As a result of extensive research, the present inventors have discovered that the above problems can be solved by using (A) niacinamide and (B) an acrylic silicone-treated color pigment in combination, and have thus completed the present invention.

[0008] That is, the present invention is as follows. [1] An emulsion composition comprising the following components (A) and (B): (A) Niacinamide (B) Acrylic silicone treated color pigment [2] The composition according to [1], wherein the content of component (A) is 1 to 10% by weight of the total composition. [3] The composition according to [1] or [2], wherein the content of component (B) is 0.05 to 30% by weight of the total composition. [4] The composition according to any one of [1] to [3], wherein the weight ratio (A) / (B) of the content of component (A) to the content of component (B) is 0.1 to 10. [5] The composition according to any one of [1] to [4], which is an external preparation for skin. [Effects of the Invention]

[0009] The emulsion composition of the present invention does not leave a sticky or squeaky feeling when applied, and the applied film does not become wrinkled even after a long time has passed since application. Therefore, the present invention provides an emulsion composition that is particularly suitable for use as a base makeup cosmetic. DETAILED DESCRIPTION OF THE INVENTION

[0010] The present invention will be described in detail below. In this specification, the symbol "to" means a range including the numerical values ​​before and after it. The emulsion composition of the present invention contains (A) niacinamide and (B) an acrylic silicone-treated color pigment.

[0011] (A) Niacinamide Niacinamide provides a moisturizing feeling to the skin to which the composition is applied and prevents dryness. It also has the effect of imparting a firmness to the skin to which the cosmetic composition is applied. The firmness refers to the feeling that the skin is elastic and resilient to stress.

[0012] The content of niacinamide in the cosmetic of the present invention is preferably 1 to 10 wt %, more preferably 2 to 6 wt %, even more preferably 4 to 5.4 wt %, and particularly preferably 2.5 to 5.4 wt %, based on the total amount of the cosmetic. By using the composition in such a range, the skin feels less sticky when applied, and is less likely to feel dry even after a long time has passed since application.Furthermore, the skin is more likely to feel firm after application of the composition.

[0013] (B) Acrylic silicone treated color pigment An acrylic silicone-treated color pigment refers to a color pigment that has been coated with an acrylic silicone. Here, "coating" may refer to chemical bonding or physical adsorption of the acrylic silicone to the color pigment. Typically, the coating is carried out by a standard method such as a dry treatment or a wet treatment. The acrylic silicone is a copolymer of acrylic acid monomer and silicone, and may be any of those commonly used in cosmetics. The size of the copolymer is not particularly limited, but examples include those in which the dynamic viscosity of component (B) measured at room temperature using a Cannon-Fenske viscometer is 50 to 5,000 mPa·s. Specifically, preferred examples include acrylates / dimethicone copolymers. Examples of commercially available acrylates / dimethicone copolymers include "KP-545" from Shin-Etsu Chemical Co., Ltd. The surface of the color pigment coated with the acrylic silicone is made hydrophilic.

[0053] <Production Example and Evaluation 1> Using the formulation components shown in Table 1, the oil phase component and the aqueous phase component were each heated to 70°C to dissolve, the aqueous phase component was added to the oil phase component, and the mixture was emulsified while stirring with a homomixer to prepare a water-in-oil emulsion composition. The resulting compositions were evaluated according to the following criteria, and the results are shown in Table 1.

[0054] (Non-sticky when applied) Ten expert evaluators took 0.16 g of each composition onto a sponge and applied it to the face to evaluate whether it felt sticky or not, using the following five-point scale. The total of the scores from the 10 evaluators was used to determine the evaluation result. 5: No stickiness at all 4: Almost no stickiness 3: Feels slightly sticky 2: Feeling sticky 1: Feels very sticky

[0055] (No squeaking when applied) Ten expert evaluators evaluated whether or not a creaky sensation was felt when 0.16 g of each composition was applied to a sponge and applied to the face, using the following five-point scale. The total of the scores given by the ten experts was used to determine the evaluation result. 5: No creaking at all 4: Almost no creaking 3: I feel a slight creaking sound 2: I feel a creak 1: Very creaky

[0056] (No wrinkling over time) 0.16 g of each composition was applied to a sponge on the face, and after 4 hours, 10 expert evaluators evaluated the skin creases observed using the following 4-point scale, and the total of the scores from the 10 experts was used to determine the evaluation result. 4: No wrinkles at all 3: Almost no wrinkles 2: Slightly wrinkled 1: There is obvious crease

[0057] [Table 1]

[0058] <Production Example and Evaluation 2> Using the formulation components shown in Table 2, the oil phase component and the aqueous phase component were each heated to 70°C to dissolve, the oil phase component was added to the aqueous phase component, and emulsified while stirring with a homomixer to prepare an oil-in-water emulsion composition. Each of the resulting compositions was evaluated according to the same items and criteria as in <Production Example and Evaluation 1>. The results are also shown in Table 2.
