Description

Composition with instant and long-acting oil control and moisture retention functions and preparation method and application thereof

Technical Field

The invention belongs to the technical field of cosmetics, relates to an oil-control and moisture-keeping composition, and a preparation method and application thereof, and particularly relates to an instant and long-acting oil-control and moisture-keeping composition, and a preparation method and application thereof.

Background

Oily skin is a global problem, more common in men and adolescents, and especially prominent among groups of 15-39 years of age, and is rooted in the exuberance of sebum secretion. Sebum from healthy skin plays an important role in protecting the skin barrier, protecting skin and hair from abrasion, regulating transepidermal water loss, maintaining skin biofilms, and delivering antioxidants. However, modern people face more stress and environmental pollution, sebum secretion may be disordered, oil secretion is excessive, and lipophilicity bacteria, fungi and parasitic bacteria are excessively bred, so that a series of skin problems are caused, such as inflammation, oily light, large pores, pore blockage, acne, skin thickening and darkness and the like.

In order to suppress excessive secretion of sebum and to restore the skin to a normal state, it is necessary to develop cosmetics having immediate and long-lasting oil control. Most of the oil control related cosmetics on the market aim at inhibiting sebum secretion, or simply cleaning oil, or adding powder for instantly adsorbing oil, such as silicon powder, kaolin and the like into the product by adopting a physical adsorption method, although a certain effect is achieved, the effects of instantly getting rid of oil gloss, persistently controlling oil and improving skin quality which are required by consumers are not solved. Thus, the combined effects of immediate and long-term oil control are not achieved. The oily skin can be relieved to a certain extent but the skin can not really get rid of oily light by simply cleaning the oil or adding powder for instantly adsorbing the oil, such as silicon powder, kaolin and the like, into the product by adopting a physical adsorption method.

CN106983692B discloses a plant enzyme oil-controlling acne-removing mask, which consists of a skin conditioner component, a matrix component and water, wherein the skin conditioner component comprises the following components in percentage by mass: 0.1-2% of laminaria saccharina extract, 0.5-3% of witch hazel extract, 1-5% of phellodendron extract, 0.1-1% of rapeseed oleic acid fermentation product, 0.05-0.2% of candida, 1-5% of glycerol, 0.5-10% of butanediol, 1-3% of hydroxyethyl urea, 0.5-2% of trehalose, 0.1-1% of glucose and 0.1-0.1% of sodium hyaluronate. The plant enzyme oil-control acne-removal mask provided by the invention helps skin to continuously control oil, dredge pores, refine pores, remove acnes, smooth acne marks, smooth skin feel and the like in all-around repair. Although the product has a certain long-acting oil control effect, the instant oil control effect is not good.

CN109276513A discloses a composite plant oil-control double-layer skin care water containing Acanthopanax trifoliatus powder, which consists of deionized water, EDTA disodium, glycerol, 1, 3-propylene glycol, nicotinamide, p-hydroxyacetophenone, sodium magnesium lithium silicate/tetrasodium pyrophosphate, hydroxypropyl trimethyl ammonium chloride hyaluronic acid, xylitol-based glucoside/anhydroxylitol/xylitol/glucose/water, hydrolyzed algin, grape seed extract, Acanthopanax trifoliatus stem powder, peppermint leaf extract, pterospermum pterocarpum seed extract, Chondrus crispus extract/Chondrus litura extract, sodium chloride, calcium aluminum borosilicate/silicon dioxide/titanium dioxide/tin oxide, phenoxyethanol and ethylhexyl glycerol. The natural Indian trifoliate acanthopanax bamboo stem powder is used for physically adsorbing redundant sebum, refreshing the skin, adding a plurality of natural plants, and crushing to form a skin protective film, preventing pollution and fine dust, chelating harmful heavy metals, and having the effects of relieving allergic skin, resisting oxidation, nourishing and tendering the skin. The product has good instant oil control effect, but the long-acting oil control effect is not good.

The skin really achieves the oil control, namely the oil control is acted on sebaceous glands to inhibit the excessive secretion of sebum, then a physical adsorption method is combined to achieve the combination of instant action and long-acting action, sufficient moisture is supplemented to the skin, the water and oil balance is achieved, and the skin can be healthy.

Test example 1

Erythrocyte hemolysis assay:

the erythrocyte hemolysis test is one of the alternatives of the rabbit eye irritation test (Draize test), and the basic principle is to evaluate the damage of chemicals to eye tissue cells by measuring the dissolution amount and denaturation degree of hemoglobin. The RBC test is used internationally for evaluating eye irritation studies on chemicals such as cosmetics and raw materials.

The samples of examples 1 to 6 and comparative examples 1 to 6 were subjected to hemolysis test of erythrocytes, and the irritativeness of the test samples to the surface layer of skin was evaluated based on the principle that lipids and proteins on the surface of human skin are similar to the cell membrane of erythrocytes. The test results were judged according to the RBC experimental test method and grading standards of the European Alternatives validation center (ECVAM). As shown in table 1:

TABLE 1

L/D	Grading
		>100	Has no irritation
10<L/D<100	Micro-stimulation
		1<L/D<10	Mild stimulation
0.1<L/D<1	Moderate stimulation
		L/D≦1	Severe stimulation

The test results are shown in table 2:

TABLE 2

Sample name	L/D	Evaluation of results
			Example 1	369.76	Has no irritation
Example 2	318.45	Has no irritation
			Example 3	256.55	Has no irritation
Example 4	235.78	Has no irritation
			Example 5	268.74	Has no irritation
Example 6	232.43	Has no irritation
			Comparative example 1	168.87	Has no irritation

			Comparative example 3	195.24	Has no irritation
Comparative example 4	135.27	Has no irritation
			Comparative example 5	109.36	Micro-stimulation
Comparative example 6	146.28	Micro-stimulation

As can be seen from the data in Table 2: the irritation of the composition with the functions of instant oil control and long-acting moisture retention is graded as no irritation, which shows that the composition has the characteristics of nature, mildness and no irritation.

Test example 2

Immediate skin oil secretion test:

the oil content test adopts the world recognized

The method is based on the principle of photometer, a special extinction adhesive tape with the thickness of 0.1mm absorbs grease on human skin and then becomes a semitransparent adhesive tape, the light transmittance of the semitransparent adhesive tape changes, the more grease is absorbed, the greater the light transmittance is, and therefore the content of the grease on the skin can be measured. The test probe has the greatest advantages of small volume and convenient use, and can test any part of the skin. This is an indirect measurement of the secretion of the oil glands, and the result can be used to distinguish between different skin types, making it possible to accurately understand the changes in oil caused by internal and external causes.

Selecting 12 volunteers with the age of 16-50 years, male and female, wherein the screening conditions are as follows: the sebum level is more than or equal to 150 mu g/cm after three hours of face cleaning in the morning, a half-face test comparison method is adopted, a test subject firstly cleans the face, sits for 30min in a set environment, takes the eyebrow as a boundary, divides the forehead of the test subject into a left half and a right half, firstly measures the skin oil of the left forehead and the right forehead, tests 3 times in each test area and takes an average value, respectively takes a proper amount of the oil-control moisturizing composition prepared in the examples 1-6 and the composition prepared in the comparative examples 1-6 to be smeared on the set test area of the forehead, and the test data are recorded before the test. The samples were used 30min, 60min, 120min later. Then, the change in the amount of sebum secretion from the left and right cheek halves was measured in the same manner, and the data was recorded. The results of the experiment are shown in table 3.

TABLE 3

As can be seen from the data in Table 3: the composition has good instant oil control effect, wherein the instant oil control effect of the example 1 is the best, the comparative example 3 only contains xylitol, and the test result shows that the composition does not have the oil control effect, and the comparative examples 1, 2, 4, 5 and 6 have certain oil control effect, but the oil control effect is much worse than that of the oil control moisturizing compositions of the examples 1 to 6, which shows that the synergistic effect exists in each active formula in the oil control moisturizing composition.

Test example 3

Sebum Level (CSL) test:

selecting 60 volunteers, the age of which is 16-50 years old, male and female are unlimited, and the screening conditions are as follows: after the face is cleaned in the morning for three hours, the sebum level is more than or equal to 150 mu g/cm, the face is randomly divided into 12 groups, and after the face is cleaned, each group respectively takes a proper amount of the oil-controlling moisturizing composition prepared in the example 1-6 and the composition prepared in the comparative example 1-6 to be smeared on the forehead and slightly patted to absorb the sebum, and the face-cleaning oil-controlling moisturizing composition is used once a day in the morning and at night. And testing the sebum level (CSL) of the 4 th week by using a sebum test analyzer, and taking the average value of the test results of the user and taking the sebum level 30min after the test area is cleaned as an initial value. The test results are shown in table 4:

TABLE 4

Sample name	Degree of reduction in sebum levels
		Example 1	-42.35％
Example 2	-22.87％
		Example 3	-26.56％
Example 4	-31.58％
		Example 5	-39.87％
Example 6	-33.48％
		Comparative example 1	-13.20％
Comparative example 2	9.82％
		Comparative example 3	1.73％
Comparative example 4	-9.62％
		Comparative example 5	8.32％
Comparative example 6	-5.69％

From the data in table 4, it can be seen that: the oil-controlling and moisturizing compositions prepared in examples 1-6 all have good effect of reducing the sebum level, and the sebum level is reduced by-22.87% -42.35%. Compared with the single component or the composition lacking any active ingredient prepared in comparative examples 1-6, the oil and fat secretion inhibiting degree is higher, which shows that the oil-controlling and moisture-preserving composition has scientific and reasonable component proportion, plays a role in synergy and can inhibit effective oil and fat secretion.

Test example 4

Number of Active Pores (NAP) and percent skin Surface Sebum (SSP) test:

selecting 60 volunteers, the age of which is 16-50 years old, male and female are unlimited, and the screening conditions are as follows: the sebum level is more than or equal to 150 mu g/cm after three hours of face cleaning in the morning². The skin care composition was randomly divided into 12 groups, and after cleansing the face, an appropriate amount of the oil-controlling moisturizing composition prepared in examples 1 to 6 and the composition prepared in comparative examples 1 to 6 was applied to the forehead and gently patted to absorb the moisture, and the composition was used once a day, morning and evening. The Number of Active Pores (NAP) and the percentage of skin Surface Sebum (SSP) were measured at week 4 using the active skin surface analysis system, and the user test results were averaged to take the Number of Active Pores (NAP) and the percentage of skin Surface Sebum (SSP) 30min after cleaning the test area as initial values. The test results are shown in table 5:

TABLE 5

Sample name	Reduction degree of active pore number	Reduction of sebum percentage on skin surface
			Example 1	-39.71％	-51.84％
Example 2	-23.67％	-35.53％
			Example 3	-25.48％	-41.66％
Example 4	-30.20％	-43.82％
			Example 5	-36.39％	-49.69％
Example 6	-33.49％	-45.35％
			Comparative example 1	-16.34％	-20.47％
Comparative example 2	5.68％	18.21％
			Comparative example 3	-3.08％	-5.12％
Comparative example 4	-17.23％	-24.65％
			Comparative example 5	2.82％	6.22％
Comparative example 6	-14.35％	22.58％

From the data in table 5, it can be seen that: the oil control and moisture preservation composition has the advantages that the oil control effect of the oil control and moisture preservation composition is stronger than that of a single component or a composition lacking any active component, and the oil control and moisture preservation composition has good oil control and pore shrinkage effects after the three active components are matched with each other and have synergistic effects. Meanwhile, as shown in the experimental structure oil control, in the comparative examples 2 and 5, natural bamboo powder is used alone or natural bamboo powder is compounded with xylitol, although the instant physical adsorption oil control effect is achieved, from the result of an oil control test for 4 weeks, the activity of pores is increased, and the phenomenon of controlling oil over time is shown, which indicates that the combination of physical and biological methods is required to be considered for improving the condition of oily skin, so that the instant oil control effect is required, and the secretion of sebaceous gland sebum, the activity of pores and other indexes are improved.

Test example 5

In vitro efficacy evaluation test:

3 liver homogenates of male SD rats were used to prepare 12 groups of identical 5 alpha-reductase solutions, each group was supplemented with one of the samples of the compositions of examples 1-6 or comparative examples 1-6, and the inhibition rate of the oil control composition containing the oil control composition on the 5 alpha-reductase solution was examined through a series of reaction systems, and the higher the inhibition rate is, the better the oil control effect is. The test results are shown in table 6:

TABLE 6

From the data in table 6, it can be seen that: the oil-controlling and moisturizing compositions prepared in examples 1-6 generally have higher inhibition rate on 5 alpha-reductase liquid than the compositions prepared in comparative examples 1-6, and the inhibition rate on 5 alpha-reductase liquid is between 35.74% and 67.43%, wherein the inhibition rate of example 1 is the highest and reaches 67.43%, so that the oil-controlling effect is the best.
