  Cosmetics such as lotion, milky lotion, cream, etc. are often applied directly to the skin from the container, and the skin feel when applying cosmetics is an important factor in evaluating and selecting cosmetics. It is considered as one of The user's favorite skin feel varies, and it is actually difficult to prepare a large number of cosmetics in order to satisfy all requirements. Therefore, the actual situation is that the user selects a product that is close to the taste from limited products.

In recent years, methods for evaluating skin properties such as the amount of sebum, moisture, and skin surface morphology of skin have been developed (Non-Patent Documents 1 and 2), and counseling and advice are given in the selection of cosmetics at the cosmetic sales site. It has been broken. In addition, (semi-) made-to-order cosmetics that contain optimal ingredients according to the individual skin characteristics and demands of users are also provided. However, when counseling or giving advice, cosmetics with a skin feel that matches the user's preference are prepared on the spot, and the skin feel of the product is not actually evaluated. Has not been fully satisfied.
Cosmetics are usually manufactured by measuring and blending a large number of raw materials individually at a production site such as a laboratory or a factory, but the work is complicated. This complication has also contributed to the fact that cosmetics having a skin feel that meets the user's preferences cannot be prepared and presented to the user.

The biaxial coordinates used in the present invention are composed of two axes in which the degree of the first cosmetic selection element is the X axis and the degree of the second cosmetic selection element is the Y axis. On the biaxial coordinate plane, the degrees of the first and second cosmetic selection elements of each adjustment cosmetic and each sample cosmetic are plotted as coordinate values. The number of X-axis scales and the number of Y-axis scales indicating the degree of the first and second cosmetic material selection elements are appropriately selected. The number of scales indicates a number of 1 or more, but it is usually 3 to 200, particularly 5 to 100 is practical. In addition, it is preferable that the number of scales of the X axis and the Y axis is the same from the viewpoint of easy evaluation and positioning of the cosmetic selection element.
Hereinafter, the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows two-axis coordinates in which the degree of the first cosmetic selection element is the X axis and the degree of the second cosmetic selection element is the Y axis, and the scale number of the X axis is n and the scale of the Y axis. On the biaxial coordinate plane whose number is m, the degree of the first and second cosmetic selection elements of the first to fourth adjustment cosmetics P to S and the first to fifth sample cosmetics A to E is set. These are the biaxial coordinates plotted as coordinate values. n and m each represent a number of 1 or more. The coordinate values of the adjustment cosmetics P to S are P (0, m), Q (0, 0), R (n, 0), and S (n, m). The coordinate values of the sample cosmetics A to E are A (n / 2, m / 2), B (0, m / 2), C (n, m / 2), D (n / 2, 0), E (n / 2, m).

First, at least two or more of the sample cosmetics A to E are evaluated by a cosmetics selector. The sample cosmetic to be evaluated for trial use is preferably at least one of sample cosmetic A and sample cosmetics B to E, and particularly preferably all five types of sample cosmetics A to E.
In the trial evaluation, when one of the cosmetic selection elements is a color, for example, the color of the sample cosmetic is evaluated, and when it is a scent, the scent of the sample cosmetic is evaluated. When one of the cosmetic selection elements is skin feel, the skin feel of the sample cosmetic is evaluated. The skin feel is evaluated by applying a sample cosmetic to the skin of the cosmetics user. The skin to which the sample cosmetic is applied is not particularly limited, and examples thereof include skins such as the face, hands, and arms. The application amount per application is not particularly limited, but is preferably 0.5 to 5 ml when only the face is used, and 0.1 to 0.5 ml is preferable for the back of the hand.

  Next, the cosmetic material selector is made to select the positions of the first and second cosmetic material selection elements that are preferred on the biaxial coordinate plane. FIG. 1 shows a state in which the coordinates a and i 'selected by the cosmetics selection person are plotted.

Next, the blending mass ratio of the first to fourth adjustment cosmetics P to S at the selected position is calculated from the selected coordinate value and the coordinate value of each adjustment cosmetic.
Specifically, a combination of three cosmetics from the first to fourth adjustment cosmetics P, Q, R, and S according to the coordinate values (a, b) of the coordinates a, i ′ selected in FIG. Is selected, and the blending mass ratio is calculated for these three cosmetics. There are four combinations of the three cosmetics for adjustment (P, Q, R), (P, R, S), (P, Q, S), (Q, R, S), and (P, Q , R) or (P, R, S), or (P, Q, S) or (Q, R, S).

Taking the case where the combination of the cosmetics for adjustment is (P, Q, R) and (P, R, S) as an example, the blending mass ratio is calculated as follows.
When the coordinate value (a, b) of the selected coordinate a is a + b ≦ (n + m) / 2, the following formula (1):
Q: R: P = {(n + m) / 2} -ab: a: b (1)
Thus, the blending ratio of the first adjustment cosmetic P, the second adjustment cosmetic Q, and the third adjustment cosmetic R is calculated.
On the other hand, when the coordinate value (a, b) of the coordinate a ′ is (n + m) / 2 <a + b ≦ n + m, the following formula (2):
S: P: R = a + b-{(n + m) / 2}: {(n + m) / 2} -a: {(n + m) / 2} -b (2)
Thus, the blending ratio of the fourth adjustment cosmetic S, the third adjustment cosmetic R, and the first adjustment cosmetic P is calculated.
In the above formula, n is the X coordinate value of R and S, and m is the Y coordinate value of P and S.

  The cosmetic of the present invention is obtained by blending the first to fourth adjustment cosmetics based on the calculated blending mass ratio.

  In the present invention, it is preferable to prepare the first to fourth adjustment cosmetics and the first to fifth sample cosmetics according to the skin quality classification. Here, examples of the skin quality classification include oily skin, oily dry skin, normal skin, oil-deficient skin, and dry skin. Preliminarily evaluate the skin properties such as the amount of sebum and moisture of the subject's skin, the skin surface form, etc., determine the skin quality, and then use the above-described steps using each adjustment cosmetic and each sample cosmetic according to the skin quality By preparing a cosmetic, the cosmetic more suitable for the skin of the subject can be provided.

  The cosmetic of the present invention can be produced according to a conventional method, and can be in any dosage form, but is preferably in a liquid, gel, or emulsion form, and particularly preferably in a liquid form. . The emulsified cosmetic may have any shape of a water-in-oil type, an oil-in-water type, and a multi-emulsion. The cosmetics of the present invention are preferably skin care cosmetics such as lotions, emulsions, creams, cleaning agents, massages and the like.
