Description

  The present invention is a stage called “when it stops” at the stage when the cosmetic film is almost completed on the skin, and there is no sense of discomfort that suddenly increases in weight (hereinafter abbreviated as “discomfort when stopping”), and storage over time The present invention relates to an oil-in-water emulsified cosmetic that is excellent in stability and provides a flexible decorative film.

Conventionally, it is known that the water resistance and makeup sustainability of cosmetics are improved by blending a resin component with an oil-in-water emulsified cosmetic (see, for example, Patent Documents 1 to 3).
However, when a resin having a high film-forming property such as those in References 1 to 3 is blended, the secondary adhesion prevention effect and water resistance of the cosmetic itself are improved, but the composition of the volatile component such as water in the outer phase volatilizes. When the ratio of the resin component in the interior increases, the spread spreads worsens, and at the time when it is called “when it stops” at the stage when the decorative film is almost completed, there may be a feeling of strangeness that the spread suddenly becomes heavy. Furthermore, with conventional film-forming resins, the decorative film is hard and lacks flexibility, so the decorative film cannot follow the movement due to changes in facial expression, causing the film to sway, feel sticky, and maintain stable storage. Sexuality sometimes worsened.

  Therefore, it is conceivable to increase the content of liquid oils and polyhydric alcohols in order to solve the uncomfortable feeling when stopping with the conventional film-forming resin and the tension of the decorative film. In some cases, the storage stability of the emulsified cosmetic composition may be deteriorated, such as a feeling of use such as a fresh spread, and a separation may be observed. Moreover, the fresh feeling of use and the uncomfortable feeling at the time of a stop have the tendency to worsen by containing powder. In particular, makeup bases need to improve the makeup effect of the cosmetics themselves, and make it easier to apply cosmetics on top of them. The flexibility of the cosmetic film that can be followed is an important factor.

  The present invention provides a makeup effect that is durable, has a fresh feeling of use and good storage stability of an oil-in-water emulsified cosmetic, has no discomfort when stopping, and provides a flexible cosmetic film An oil-type emulsified cosmetic is provided.

  In view of the above situation, as a result of intensive studies, the present inventor found that a combination of (sodium acrylate / acryloyldimethyltaurine sodium) copolymer and a specific dextrin fatty acid ester does not cause a sense of incongruity when stopping and is fresh. It was found that the feeling of use was maintained, and that the makeup effect was sustained by forming a flexible cosmetic film on the skin, and the present invention was completed.

That is, the present invention includes the following components (a) to (c):
(A) An esterified product of dextrin and a fatty acid, wherein the dextrin has an average polymerization degree of glucose of 3 to 150, and the fatty acid is one or more of branched saturated fatty acids having 4 to 26 carbon atoms. More than 50 mol% and not more than 100 mol%, linear saturated fatty acid having 2 to 22 carbon atoms, linear or branched unsaturated fatty acid having 6 to 30 carbon atoms and cyclic saturated or unsaturated having 6 to 30 carbon atoms A dextrin fatty acid ester containing 0 mol% or more and less than 50 mol% of one or more selected from the group consisting of fatty acids and having a degree of substitution of fatty acids per glucose unit of 1.0 to 3.0 (B) (Sodium acrylate / acryloyldimethyltaurine sodium) copolymer (c) An oil-in-water emulsified cosmetic comprising water.

It is an oil-in-water emulsified cosmetic from which a certain cosmetic film is obtained.

Hereinafter, the present invention will be described in detail.
The component (a) used in the present invention is an esterified product of dextrin and fatty acid, and the average polymerization degree of glucose of dextrin is 3 to 150, and the fatty acid is one or two of branched saturated fatty acids having 4 to 26 carbon atoms.

The degree of substitution of fatty acids with component (a) dextrin is 1.0 to 3.0, preferably 1.2 to 2.8 per glucose unit. When the degree of substitution is less than 1.0, the dissolution temperature in liquid oil or the like is as high as 100 ° C. or higher, and coloring or a specific odor is not preferable. Component (a) can enhance the durability of the cosmetic effect by forming a film.

The dextrin fatty acid ester of component (a) of the present invention has the following characteristics.
(1) Liquid oil does not gel when mixed with liquid oil.
“Liquid oil does not gel” means that when liquid paraffin having a kinematic viscosity of 8 mm 2 / s at 40 ° C. according to ASTM D445 measurement method is liquid oil, the liquid paraffin containing 5% by mass of dextrin fatty acid ester is 100 When it melt | dissolves at degreeC and a viscosity is measured at 25 degreeC after 24 hours, it means that a viscosity is below the detection limit of Yamaco DIGITAL VISCOMATE viscometer VM-100A (vibration type) (made by Yamaichi Denki Co., Ltd.). In addition, when gelatinizing, it can confirm by detecting a viscosity.

(2) The film formed by the dextrin fatty acid ester of component (a) has a specific range of tackiness.
The “tackiness” is determined by applying the dextrin fatty acid ester to a support and bringing the other support into surface contact from a state where they are separated from each other, then retracting them and separating them. When expressed by the load change (maximum stress value) applied to the contact point until the film is formed, a light liquid isoparaffin solution containing 40% by mass of the dextrin fatty acid ester is formed on a glass plate with a 400 μm-thick applicator and dried. , Texture analyzers, eg texture analyzer TA.

(Evaluation method)
Each of the 10 professional evaluation panels evaluated each sample in the above (i) to (d) using the following absolute evaluation in five levels, and the average score of each sample was determined using a four-step criterion. . Regarding (d), after applying the sample, the panel was allowed to live a normal life, and the decorative film after 6 hours was evaluated. (B) is whether you can get a fresh feeling when used, (b) whether you feel a sense of incongruity that suddenly grows heavy at the time called "stop", We evaluated whether we felt flexibility.

(Absolute evaluation criteria)

From the results shown in Table 1, the oil-in-water makeup base of the present invention has a good cosmetic effect, has the fresh feeling of use and good storage stability of oil-in-water emulsified cosmetics, Thus, it was possible to obtain a flexible decorative film.
In Comparative Example 1 which does not contain the component (a), the durability of the makeup effect was not particularly obtained, and the uncomfortable feeling at the time of stopping was inferior.
In the comparative example 2 which does not contain a component (b), especially storage stability was bad, and it was inferior in the point of the discomfort at the time of a stop, and the softness | flexibility of a decorative film. On the other hand, Comparative Example 3 using a carboxyvinyl polymer instead of the component (b) did not have a durable cosmetic effect and was not satisfactory in that it was separated and poor in storage stability. In Comparative Example 4 in which trimethylsiloxysilicic acid was used instead of component (a), the cosmetic film lacked in flexibility, and the cosmetic film became hard, so that it was satisfactory in that the durability of the cosmetic effect was reduced. I couldn't. In Comparative Example 5 in which a vinyl acetate polymer was used instead of component (a), the feeling of discomfort at the time of stopping was felt, the cosmetic film lacked in flexibility, and the cosmetic film became hard, which is satisfactory in terms of durability of the makeup effect. I couldn't get anything.
