Description

  The present invention relates to an oil-in-water emulsified cosmetic excellent in use feeling at the time of application, skin feeling on the next day, and stability over time.

  Conventionally, cosmetics containing various types of oils have been developed in order to impart an excellent moisturizing feeling to cosmetics.

  However, with conventional cosmetics, by increasing the amount of oil, a moist feeling immediately after application can be obtained, but the feeling of use at the time of application is also poor, and the next day's skin feeling (moisture / softness of skin) is good Was not obtained.

  Recently, attempts have been made to prepare cosmetics using phospholipids, which are natural ingredients. For example, emulsified cosmetics that combine natural surfactants such as lecithin, higher alcohols that are liquid at room temperature, and glycerin have been introduced to have high safety, affinity for skin, and excellent moisture retention. (For example, refer to Patent Document 1).

  On the other hand, fats and oils extracted from plant seeds are widely used in conventional foods. For example, as fat raw materials for edible spreads, fat substitutes derived from palm fat, seed oil triacylglyceride components and optionally fat substitutes from seed oil There exists what mix | blended the thing (for example, refer patent document 2). In addition, there are health foods (for example, see Patent Document 3) containing cupuas fat derived from cupuas seeds.

  However, most of the oils and fats extracted from plant seeds that have been used in these conventional foods have not been studied for blending into cosmetics like the former, even if blended into cosmetics, Only the effect of improving the skin protection effect like the latter has been found, and there is no mention of effects such as a feeling of use at the time of application, a feeling of the skin on the next day, and a stability over time.

Furthermore, from the viewpoint of usability, the apparent viscosity at a shear rate of 10 ⁻³ (1 / s) is more preferably 1000 (Pa · s) or more.

In addition, the apparent viscosity in this invention is each viscosity measured at each shear rate using a viscoelasticity measuring apparatus etc. For example, with a rheometer (Physica MCR301) manufactured by Anton Paar, using a cone plate type (diameter 50 mm) as a measurement jig, at a measurement temperature of 25 ° C., a shear rate of 10 ⁻⁴ (1 / s) Increase the speed to 10 ⁴ (1 / s) and measure the apparent viscosity at each shear rate. At this time, the measurement time is set from 120 seconds at a shear rate of 10 ⁻⁴ (1 / s) to 3 seconds at 10 ⁴ (1 / s), and four points are measured for each digit of the shear rate.

The oil-in-water emulsified cosmetic of the present invention has a shear rate of 10 ⁻² (1 / s) to 10 ¹ (1) from the viewpoint of usability in the flow curve of shear rate (1 / s) and shear stress (Pa). More preferably, there are one or more inflection points between / s). The slope of the tangent at this inflection point may be positive or negative.

An example of the flow curve is shown in FIG. In FIG. 1, the horizontal axis is the shear rate (1 / s), the vertical axis is the shear stress (Pa), and both are logarithmic scales (log ₁₀ ). In this example, the flow curve 1 shows the value of the shear stress (Pa) in the coordinates when the speed is increased from a shear rate of 10 ⁻⁴ (1 / s) to 10 ⁴ (1 / s). This flow curve 1 has a first inflection point 2 between shear rates 10 ⁻³ (1 / s) and 10 ⁻² (1 / s), and 10 ⁻¹ (1 / s) and 100 ^0. There is a second inflection point 3 between (1 / s), and a third inflection point 4 between 10 ⁰ (1 / s) and 10 ¹ (1 / s). In the present invention, it is preferable to have the inflection points 3 and 4 between the shear rate of 10 ⁻² (1 / s) to 10 ¹ (1 / s), while the shear rate of 10 ⁻² ( Even if the inflection point 2 is outside the range of 1 / s) to 10 ¹ (1 / s), the effect of the present invention is not particularly affected. This flow curve 1 has two inflection points 3 and 4 between a shear rate of 10 ⁻² (1 / s) and 10 ¹ (1 / s), but in the present invention, there is at least one inflection point. If so, the effect of the present invention is preferable. On the other hand, there may be any number of inflection points outside the range of the shear rate of 10 ⁻² (1 / s) to 10 ¹ (1 / s). Of course, there are no particular restrictions on the slope of the tangent at the inflection point of the flow curve, the displacement of each convex portion, or the like.

  In addition, the oil-in-water type emulsified cosmetic which shows the flow curve 1 in FIG. 1 can also be represented by the curve 5 in which the value of the apparent viscosity (Pa · s) at the shear rate (1 / s) is shown as coordinates. In this case, the vertical axis represents the viscosity (Pa · s), and the value of the viscosity (Pa · s) at each point of the shear rate (1 / s) is the value of each point of the shear rate (1 / s) in the flow curve 1. The value obtained by dividing the value of each point of stress (Pa) there. (The notation and scale when the vertical axis is viscosity (Pa · s) are omitted in the figure.)
