TABLE 2 grading Standard of adverse skin reactions

TABLE 3 results of the spot test on human skin of the face cleansers prepared in examples 1 to 6 and comparative examples 1 to 11

As can be seen from the data in table 3, after the mild moisturizing facial cleanser prepared in examples 1 to 6 of the present invention is applied to the curved side of the arm, the skin reactions of the tested volunteers are all negative, the grade is 0, and the mild moisturizing facial cleanser prepared in examples 1 to 6 has no adverse reaction on the skin of the human body according to the judgment standard of the skin spot test of the human body in the cosmetic hygiene standard (2007 edition).

Compared example 1, because the lauryl glucoside solution and the lauryl hydroxy sulfobetaine alkali are not added in the phase C, the lauryl glucoside solution and the lauryl hydroxy sulfobetaine alkali are not added in the compared example 2, the mild performance of the facial cleanser prepared in the compared examples 1-2 is reduced, the irritation is increased, because the gentiana lutea root extracting solution and the cladosporium polysaccharum polysaccharide are not added in the compared example 4, because the gentiana lutea root extracting solution and the cladosporium polysaccharum polysaccharide are not added in the phase C, the antibacterial and anti-inflammatory effect is reduced in the compared example 5, the irritation caused by the surfactant is difficult to relieve, the irritation of the facial cleanser is expected to be increased, the skin is easy to generate erythema, and after the facial cleansers prepared in the other compared examples are smeared, the tested volunteers have no phenomena of edema, erythema and the like, the skin reactions are all negative, and the facial cleanser is milder, non-.

Second, long-acting water-locking and moisture-keeping effect test

170 female volunteers of 20-30 years old and dry skin were selected and randomly divided into 17 groups of 10 persons each, and 170 volunteers were acclimatized at room temperature of (23 + -1) ° c and humidity of (50 + -5)% for 30min before the test, and skin water content was measured using a corneometer CM825 test probe, wherein 6 groups of volunteers used the face cleansers prepared in examples 1-6, respectively, the remaining 11 groups used the face cleansers prepared in comparative examples 1-11, and the corneometer CM825 test probe was used to measure the water content of the stratum corneum of the volunteer's face once after 1h, 2h, and 3h, respectively, and the elasticity index R2 of the fixed region was measured using a skin elasticity tester MPA580 (germany CK), and the measurement results are shown in table 4.

Table 4 long-acting water-retaining and moisturizing effect test of facial cleansers prepared in examples 1 to 6 and comparative examples 1 to 11

As can be seen from the data in table 4, the mild moisturizing facial cleanser prepared in embodiments 1 to 7 of the present invention has the advantages of high facial moisture content and obvious moisturizing effect after 1 hour of facial cleansing, and has strong water locking and heat preserving effects after 2 to 3 hours of facial cleansing, so that the skin is not dry, the water locking effect is strong, the facial moisture is not easy to run off, the skin is kept moist and not tight for a long time, the skin elasticity is obviously increased, the stratum corneum can be repaired, and the skin is protected.

Comparative example 1 since lauryl glucoside solution and lauryl hydroxysultaine solution were not added to phase C, comparative example 2 As the amounts of lauryl glucoside solution and lauryl hydroxysulfobetaine solution used in phase C were decreased, it was found from the results that the facial cleanser prepared in comparative example 1 had a decreased water-holding and moisture-retaining ability on the facial skin as compared with examples 1 to 6, the facial cleanser prepared in comparative example 2 has increased water-holding and moisturizing abilities as compared to those of comparative example 1, but the effect is inferior to those of the facial cleansers of examples 1 to 6, comparative example 3 since the amounts of lauryl glucoside solution and lauryl hydroxysultaine solution in phase C were increased, the cleaning ability was strong, the moisturizing ability of the face is reduced, the face is easy to dry and stretch, and the water content is low, which shows that the water locking and moisturizing ability of the facial cleanser can be improved by adding the lauryl glucoside solution and the lauryl hydroxysulfobetaine solution with the specified dosage into the facial cleanser.

In comparative example 4, as the cladosporium cucumerinum polysaccharide and the gentiana lutea root extracting solution are not added in the phase C, the detection result shows that the moisture content of the face is 51.6% 1 hour after face cleaning, the moisture content is reduced to 43.7% after 1 hour, and the moisture content of the face is 39.2% after 1 hour, which is not much different from the moisture content of the face before cleaning and the elasticity is not obviously increased, which indicates that the cladosporium cucumerinum polysaccharide and the gentiana lutea root extracting solution are added in the facial cleanser, so that the moisture content and the elasticity of the face skin can be improved after the face skin is cleaned, and the skin has elasticity after long-time water moistening.

The comparative example 5 is that the dosage of the cladosporium polysaccharide and the gentiana lutea root extracting solution in the C phase is reduced, and the moisturizing, water locking and moisture preserving effects of the facial cleanser are reduced, and the comparative example 6 is that the dosage of the cladosporium polysaccharide and the gentiana lutea root extracting solution is increased, so that the antioxidant effect is improved, the moisture preserving and water locking effects of the facial cleanser are reduced, and the phenomenon of dryness and tightness is easy to occur.

Comparative example 7 since no behenyl alcohol and polyglycerin-10 stearate were added to phase B, the spreadability of the cleanser on the face was poor, and after the cleanser prepared in comparative example 3 was used to clean the skin of the face, although the cleansing cleanser had the water-locking and moisturizing effects, the effects were not as prominent as those of the cleansers of examples 1 to 6, and the elasticity increased very slowly, indicating that the incorporation of behenyl alcohol and polyglycerin-10 stearate into the cleanser could increase the degree of facial moisturization and improve the elasticity of the skin.

In comparative example 8, as the hydrolyzed sodium hyaluronate is not added in the phase A, the water content of the skin is increased after the skin is cleaned, but after 3 hours, the water content is only 38.9%, the water locking and moisturizing effect is poor, and the elasticity is slowly increased, which indicates that the water locking and moisturizing effect of the facial cleanser can be improved by adding the hydrolyzed sodium hyaluronate.

Compared with the examples 1-6, the water retention and moisture retention capacity of the facial cleanser is not obviously increased due to the fact that the dosage of the hydrolyzed sodium hyaluronate is reduced in the comparative example 9, the water retention and moisture retention capacity of the facial cleanser to skin is reduced, and the elasticity is slowly increased due to the fact that the dosage of the hydrolyzed sodium hyaluronate is too large in the comparative example 10, so that the water retention and moisture retention capacity of the facial cleanser can be improved due to the fact that the hydrolyzed sodium hyaluronate of the facial cleanser is required to be within the specified dosage of the facial cleanser.

Comparative example 11 is a facial cleanser prepared in the prior art, and the facial cleansers prepared in examples 1 to 6 of the present invention have excellent long-acting moisturizing effect and skin elasticity improving effect by comparing the moisturizing effect and the elasticity increase.

Third, detection of decontamination and whitening effect

1. And (3) testing the decontamination effect: selecting 170 female volunteers aged 20-30 years, 85 of which are oily skin subjects and 85 of which are dry skin subjects, randomly dividing 170 volunteers into 17 groups of 10 persons each, wherein 5 oily skin subjects and 5 dry skin subjects, using forehead and bilateral nasal wings as test areas, applying the facial cleanser prepared in examples 1-6 to 1-6 groups of volunteers and the facial cleanser prepared in comparative examples 1-11 to 7-17 groups of volunteers, and using the method: the preparation is applied for 1 time in the morning and evening, and continuously for 30 days, and when in use, a small amount of water is mixed with the face cleanser, and the mixture is gently kneaded until the mixture is uniformly mixed, and then the mixture is coated to a designated area; skin oil content before and after using the cleanser was measured using the CBS skin test analysis system (CBS-1900) of tai-late borescope, and the skin oil removal rate, which is (skin oil content before use-skin oil content after use)/skin oil content before use × 100%, was calculated according to the following formula to evaluate the cleansing effect of the product, and the measurement results are recorded in table 5;

2. 170 female volunteers aged 18-50 years are selected and randomly divided into 17 groups of 10 persons, and the volunteers in each group are respectively cleaned in the morning and at night and are respectively cleaned in the morning and at night, the facial cleansers prepared in examples 1 to 6 and comparative examples 1 to 11 were applied to the face, continuously used for 30 days, under the environment of the ambient temperature of 25 plus or minus 4 ℃ and the relative humidity of 48 plus or minus 5 percent RH, a MEXAMETER MX16 skin pigment analyzer is adopted, the melanin contents of the facial skin of the volunteers were measured 1 day before the use of the product and 30 days after the continuous use (average value per group), and the melanin inhibition rate (black pigment content 1 day before the use-melanin content 30 days after the use)/melanin content 1 before the use x 100%, and the melanin inhibition rates obtained by the tests of the face cleansers prepared in examples 1 to 6 and comparative examples 1 to 11 were as shown in table 5.

Table 5 stain removal and whitening effect test of the facial cleansers prepared in examples 1 to 6 and comparative examples 1 to 11

As the oil secretion of dry skin is less, it can be seen from the data in table 5 that the cleansing cream prepared according to the method in examples 1 to 6 has a small cleansing power for dry skin, which indicates that the cleansing cream prepared according to examples 1 to 6 of the present invention does not excessively remove the oil of dry skin, does not harm skin, has a strong cleansing power for oily skin, can remove excessive oil secreted on the skin surface of a user with oily skin, and has a good melanin inhibiting effect, can inhibit the yellow and dark complexion of the face, prevent melanin deposition, improve complexion, and have a good whitening effect.

Comparative example 1 since lauryl glucoside solution and lauryl hydroxysulfobetaine solution were not added to phase C, it can be seen from the data in table 5 that the cleansing effect of the cleansing cream prepared in comparative example 1 was reduced regardless of dry skin or oily skin, indicating that the cleansing cream could improve the cleansing power of the cleansing cream on oily skin and dry skin by the synergistic use of lauryl glucoside solution and lauryl hydroxysulfobetaine solution.

Comparative example 2 because the dosage of lauryl glucoside liquid and lauryl hydroxy sulfobetaine solution in the C phase is reduced, compared with the detection result of comparative example 1, the cleaning power of the comparative example 2 on dry skin and oily skin is increased, but the effect is not as good as that of examples 1-6 of the invention, and the dosage of lauryl glucoside liquid and lauryl hydroxy sulfobetaine solution in the C phase is obviously increased, so that the cleaning power of the facial cleanser on dry skin and oily skin is higher, the skin is easy to dry and stretch, and the water content is reduced, which shows that the dosage of lauryl glucoside liquid and lauryl hydroxy sulfobetaine solution in the facial cleansers prepared in examples 1-6 of the invention can effectively control the cleaning power on the faces of people with different skin types within the dosage specified by the invention, and the facial water is not tight.

Comparative example 4, the starfish branch and tube polysaccharide and the radix gentianae lutescens extract are not added in the phase C, the cleansing cream prepared in comparative example 4 has a slightly different decontamination effect on dry skin and oily skin from examples 1-6, but has a small melanin inhibition rate and a poor whitening and skin brightening effect, and comparative example 5, the dosage of the starfish branch and tube polysaccharide and the radix gentianae lutescens extract in the phase C is reduced, although the melanin inhibition rate is improved compared with comparative example 4, the effect is poor compared with examples 1-6 of the invention, comparative example 6, the dosage of the starfish branch and tube polysaccharide and the radix gentianae lutescens extract in the phase C is increased, the removal rate of oil is obviously increased, the face is easy to dry and tight, and the melanin inhibition rate has no obvious change compared with examples 1-6, which shows that the dosage of the starfish branch and tube polysaccharide and the radix gentianae lutescens extract in the cleansing cream of the invention is within the dosage specified in the invention, can effectively inhibit melanin pigmentation, brighten skin color, and achieve the effects of whitening and brightening skin.

In comparative example 7, since behenyl alcohol and polyglycerin-10 stearate were not added to phase B, the spreadability on the facial skin was poor, and it was difficult to remove much oil and fat, the oil and fat removal rate decreased, and the melanin inhibition rate was not greatly affected.

In comparative example 8, as the hydrolyzed sodium hyaluronate is not added in phase A, the free radical scavenging effect and the lipid peroxidation inhibiting effect of the facial cleanser are reduced, so that the oil scavenging rate and the melanin inhibiting rate of the facial cleanser are reduced, which indicates that the hydrolyzed sodium hyaluronate can improve the cleaning power and the whitening and skin-brightening effects of the facial cleanser.

In comparative example 9, the amount of hydrolyzed sodium hyaluronate in phase A is reduced, the efficiency of scavenging free radicals and inhibiting lipid peroxidation is reduced, so that the oil removal rate and the melanin inhibition rate are reduced compared with those in examples 1-6, while in comparative example 10, the amount of hydrolyzed sodium hyaluronate in phase A is increased, the capacity of scavenging free radicals is increased, the oil removal rate is improved, and dry and tight face is easy to appear after face cleaning, but the melanin inhibition rate is not much different from that in examples 1-6, so that the amount of hydrolyzed sodium hyaluronate in the facial cleanser of the invention can be controlled within a specified amount to ensure that the facial cleanser has better cleaning power on dry skin and oily skin, and the water is not tight after face cleaning, so that the pigmentation can be prevented, and the skin color can be improved.

Comparative example 11 is a cleanser prepared by the prior art, which has a large cleansing power for dry skin, easily causes dry and tense facial skin, has an insufficient cleansing power for oily skin, and has a small melanin inhibition rate.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
