Description

High-precision foundation toning method and foundation obtained by same

Technical Field

The application belongs to the technical field of cosmetics, and particularly relates to a high-precision foundation toning method and a foundation obtained by the same.

Background

In recent years, color cosmetics have become increasingly popular with modern urban women in china. The facial makeup is the largest sub-class in the market of the Chinese makeup (secondly, the lip makeup), and data show that the makeup market in the facial makeup is more rapidly developed, and the statistical data of Chinese makeup product market demand and investment planning analysis report issued by the forward-looking industry research institute shows that the Chinese makeup market scale reaches 344 hundred million yuan in 2017 and is about 206 million yuan; in 2018, the makeup market in China reaches 376 billion yuan, and the makeup market is about 226 billion yuan. By combining the proportion of the makeup market scale and the makeup base product, the makeup market scale reaches 430 billions even more until 2019, 670 billion yuan RMB is expected to be reached in 2024, undoubtedly, the makeup base is steadily increased along with the increase of the makeup market, and 400 billion yuan RMB is expected to be broken through in 2024.

The base makeup broadly includes foundation liquid, foundation cream, concealer, foundation cream, BB/CC cream, air cushion, facial make-up cream, etc. Among them, foundation can be said to be the most basic product in the foundation products, and other foundation products can be considered to be foundation derived products. Different base makeup products are used in different makeup links, and can achieve the effects of correcting skin color, covering skin flaws, hiding pores and fine lines, brightening skin color, modifying the face and presenting healthy and perfect skin visually.

Super Minimod Cindy Crawford states in her book facial basic color cosmetics that "foundation make-up" is the most personal style item in cosmetics and is not always available to her even if she is willing to share with a friend. Since skin tone, skin type, demand are the most critical factors and they can change over time. "make-up is well drawn, and foundation makes up seven components", so it can be seen that foundation makes up the most important place in color cosmetic products.

Foundation is a cosmetic product that is applied to the entire face to provide a cosmetic finish and coverage. Common foundation colors are divided into ivory white, skin tone, purple, green, blue, yellow, and the like. The skin colors of different races, different individuals of the same race and even different parts of the face of an individual are different, so different foundations suitable for the skin colors of the individuals and even different parts must be selected for the individuals to achieve perfect makeup.

Skin color is currently measured internationally using the chromaticity system defined by the international commission on illumination (CIE for short) convention (CIE-LAB 1976 chromaticity system). CIE represents all colors by three values of L x a x B and is defined by three-dimensional coordinates, L being the vertical axis, representing luminance, and taking values from 0 (black) to 100 (white); a, B is the horizontal axis, the value of a represents the balance between red-green, positive values represent red and negative values represent green, which is mainly affected by the degree of oxygenation of the haemoglobin, the more red the skin, the higher the value of a; b represents the balance between yellow-blue, positive values indicate yellow, negative values indicate blue, and the greater the B value, the more yellow the skin.

PANTONE COLOR CARD CORPORATION scientifically measures over 1000 kinds of human skin (different ages and races) by using a spectrophotometer, collects and arranges the measured values, and then deduces the PANTONE SKINTone integrating 110 kinds of different skin colors. The color chip is specifically designed to reproduce the closest physical skin color and is the only international universal color standard that accurately matches the skin color of all humans.

Foundation colors are available on the market today in a few numbers and do not match human skin tone very precisely.

The main factors affecting the value of L were therefore found to be: titanium dioxide, red iron oxide, black iron oxide and 'titanium dioxide and black iron oxide'. The F value is 959.15 and the p value is less than 0.01 in the second equation of the a value, which shows that the second equation of the a value has significance, and the main factors influencing the a value are found as follows: titanium dioxide, red iron oxide, black iron oxide, red iron oxide and black iron oxide. The F value in the third equation of the B value is 1366.53, the p value is less than 0.0001, which shows that the third equation of the B value has significance, and the main factors influencing the B value are: titanium dioxide, yellow iron oxide, black iron oxide, yellow iron oxide and black iron oxide.

The addition amounts of titanium dioxide, iron oxide yellow, iron oxide red and iron oxide black in the phase B are respectively added and toned according to the 110 colors in the PANTONE Skinone color card.

Nonlinear regression equation

As a preferred embodiment, the nonlinear regression equation is:

equation seven: l =43.097+, 3.293, titanium dioxide-13.360, red iron oxide-0.918, titanium dioxide black iron oxide (R) ² Is 0.990,<0.01，VIF<5)；

the eighth equation: a = -3.727+1.185 titanium dioxide +14.960 iron oxide red-0.292 iron oxide black (R +) ² Is 0.922,P value<0.01，VIF<5)；

Equation nine: b =7.319+0.597 titanium dioxide +1.316 titanium dioxide yellow iron oxide-0.388 titanium dioxide black iron oxide (R) ² Has a P value of 0.958<0.01，VIF<5)；

In comparison to the linear regression equation, R ² Not only are the degrees improved, but also the VIF is less than 5, and the collinearity among the factors is eliminated. From the equations seven, eight and nine, the titanium dioxide and the iron oxide black are related to the values of L, A and B; the iron oxide red is related to L value and A value; yellow iron oxide is only related to the B value. The three-equation belongs to a quadric quadratic equation. If the required L, A and B are confirmed, only one variable (any one of titanium dioxide, iron oxide yellow, iron oxide red and iron oxide black) is confirmed, and the values of the corresponding other three variables can be easily obtained through simultaneous equations.

The method for obtaining the seventh equation, the eighth equation and the ninth equation comprises the following steps: and combining the main factors of the L, A and B values analyzed by the linear regression equation, and performing nonlinear regression analysis by means of SPSS17.0 to obtain equation four, equation five and equation six, wherein the equation four, equation five and equation six are respectively as follows:

equation four: l = +44.75458125641255+ 3.249883977183 titanium dioxide-14.34730100767540 iron oxide red +5.41364331118951 iron oxide black-1.87380078756456 iron dioxide black (R) = + 44.754581251255 + 3.2498977183 iron oxide black-1.873 ² The P value was 0.9907<0.01)。

Equation five: a = + 8.28964227091939-0.01170036319105: -12.51179865559: + 13.985724015779: + 3.49485732341327: -2.697202158545: -titanium dioxide black iron oxide (R =) ² The P value was 0.978<0.01)。

Equation six: b = +16.10348-0.025888 titanium dioxide-7.83411 iron oxide yellow +14.09569 iron oxide black +2.07520 titanium dioxide iron oxide yellow-2.88481 iron oxide black (R = iron oxide black) ² The P value was 0.9843<0.01). The analysis finds equation four, equation five and equation six R ² All the factors are higher than the linear regression equation in different degrees, but partial factors VIF are larger than 10, which indicates that collinearity exists among some factors, and the collinearity factors are tried to be eliminated by combining the linear regression result and the nonlinear regression result, so that an equation seven, an equation eight and an equation nine are obtained after optimization.

And verifying the seventh equation, the eighth equation and the ninth equation, and judging the verification indexes by using the color difference value delta E. Color in LABIn the system, the color difference Δ E represents the distance between two color points in the color space. Since Δ E integrates LAB tristimulus variations, representing a stereoscopic variation in chromaticity, this index is the most suitable evaluation index in the LAB chromaticity system. Δ E is calculated as:

color difference identification is as follows in table 5:

TABLE 5 color difference identification Table

Determination of the degree of chromatic aberration	ΔE
		Micro (difficult to distinguish with naked eyes)	0～0.5
Light and slight	0.6～2.0
		Can feel	2.1～4.0
Is obvious	4.1～6.0
		Is very big	6.1～12.0
Distinct from each other	12.1 or more

The toner ratio in table 4 is substituted into the regression equation, and the color difference Δ E between the simulated value and the measured value is verified, as a result of the verification, 102 of the 110 simulated calculated values have a color difference of less than 2 with the measured value, the occupancy rate of 92.73%, and the occupancy rate of the color difference of less than 1 of 37.3%, which means that it is difficult for a normal person to determine the color difference between the simulated value and the measured value.

Compounding design equation

The D-optimal design can minimize the variance of the regression coefficient of the fitting model and improve the prediction accuracy of the regression model. The D-optimal mixing design (D-optimal mixing design) is a design method for applying the D-optimal design to a mixing test, and has the characteristics of less experiment times, sufficient information quantity, high parameter prediction precision and multi-objective synchronous optimization.

In the model study, only table 4 is taken as a study object, the matrix material ratios (substances except titanium dioxide, iron oxide yellow, iron oxide red and iron oxide black) are simultaneously taken as a factor, and the existing data are combined for analysis to respectively obtain the following regression equations:
