The hair conditioner is matched with various surfactants to enhance the cleaning capability to scalp and skin; the pH regulator is used for regulating the pH value of the shampoo and shower gel, so that the shampoo and shower gel can better protect the skin and reduce the stimulation to the skin.

In conclusion, at least one of the saponaria officinalis extract and the carrageen crispa is selected as the skin conditioner, and the cocamidopropyl betaine in the first surfactant and the sorbitan laurate in the second surfactant are respectively and uniformly mixed with water, so that the effective dispersion is realized. The post-skin conditioner is compounded with various surfactants, so that the irritation to the skin and the scalp is further reduced while the cleaning effect of the shampoo and the shower gel is improved. The moisturizer, the chelating agent and the pH regulator are added for cooperation, so that the skin cleaning effect of the shampoo and the shower gel is further improved, and the irritation to the skin is reduced.

Preferably, the components of the skin conditioner and the weight percentage of each component in the total amount of the shampoo and the shower gel are as follows:

0.4-0.6% of soapwort extract;

0.2-0.4% of Chondrus crispus.

By adopting the technical scheme, the components of the skin conditioner are preferably selected, and the weight percentage of the components is controlled, so that the moisturizing performance of the shampoo and the shower gel is enhanced, and the irritation is reduced.

Preferably, the components of the third surfactant and the weight percentage of each component in the total amount of the shampoo and shower gel are as follows:

2-3% of sodium lauroamphoacetate;

the third surfactant is water 4-6.4%.

By adopting the technical scheme, firstly, the lauroyl amphoacetate is dispersed by adopting a third surfactant, namely water, and then the third surfactant is added into the shampoo and shower gel to be dissolved with surfactants such as cocamidopropyl betaine, sorbitan laurate and the like, so that the cleaning capability of the shampoo and shower gel is further enhanced. Meanwhile, the sodium lauroamphoacetate has small irritation and is mild, and the irritation of the shampoo and the shower gel can be reduced.

Preferably, the components of the fourth surfactant and the weight percentage of each component in the total amount of the shampoo and shower gel are as follows:

decyl glucoside 0.5-1%;

the fourth surfactant is 0.6-0.8% of water.

By adopting the technical scheme, decyl glucoside is taken as one of novel nonionic surfactants APG, has the characteristics of both nonionic and anionic surfactants, and has relatively low irritation due to extraction from plants. When decyl glucoside is compounded with surfactants such as cocamidopropyl betaine, sorbitan laurate and the like, the irritation of other surfactants is effectively reduced, and the moisturizing effect of the shampoo and the bath cream is enhanced by being matched with a moisturizing agent and a skin conditioner.

Preferably, the components of the moisturizer and the weight percentage of each component in the total amount of the shampoo and the shower gel are as follows:

The preparation method comprises the following steps: the components are mixed and stirred uniformly to obtain the shampoo shower gel.

Detection method

Experiment one: irritation test

Experimental samples: examples 1-21 and comparative examples 1-6.

Subject: 54 healthy adult Japanese big-ear rabbits (2.5-3 kg in body weight) were used and divided into 17 groups, corresponding to examples 1-21 and comparative examples 1-6, respectively.

The experimental method comprises the following steps:

the rabbit eyes were checked to be normal, and the next day 0.1mL of a shampoo/10 distilled water dilution was dropped directly into one side of each rabbit, into the conjunctival sac of the eyes, and allowed to passively close for 30 seconds.

Evaluation of irritation: the conjunctiva, cornea and iris of the tested side eye were observed 24 hours after eye dropping to see whether there was any abnormal change.

The scoring criteria were as follows: the score is 1-10, the score is given according to the change degree of the abnormal condition, and the larger the change degree is, the higher the score is, the larger the irritation is; the smaller the degree of change, the lower the score, indicating less irritation. The specified fraction is less than or equal to 3, namely the irritation meets the safety standard.

Experimental results the results of the irritation experiments of examples 1-21 and comparative examples 1-6 are shown in Table 3.

Experiment two: sensory evaluation experimental subjects: in the same area, 81 women in China with healthy lips and 25-35 years old who had no obvious skin wounds and diseases were recruited and divided into 27 experimental groups on average, and the groups were assigned to examples 1-21 and comparative examples 1-6, respectively.

The experimental method comprises the following steps:

grading the cleanliness degree; the subjects used the shampoo and bath according to examples 1-21 and comparative examples 1-6, respectively, with 5ml per shampoo and 6ml per bath. Two weeks of continuous use, the testers scored according to the experience of use.

The scoring criteria were as follows:

the degree of cleanliness: 1-10 points, the better and the fresher the degree of cleaning, the higher the score, the worse the degree of cleaning, the worse the degree of refreshing, and the lower the score.

The hair care effect is as follows: 1-10 points, the better the clean, the fresher the hair, the softer the hair, the higher the score, the worse the clean, the less cool, the softer the hair, the lower the score.

The experimental results are as follows: the experimental results of examples 1 to 21 and comparative examples 1 to 6 are shown in Table 3.

Experiment three: moisture retention test

Experimental samples: examples 1-21 and comparative examples 1-6.

Experimental subjects in the same area, 81 women in China with healthy lips and without obvious skin wounds and diseases in the age of 25-35 years were recruited and divided into 27 experimental groups on average, which correspond to examples 1-21 and comparative examples 1-6, respectively.

An experimental instrument: skin moisture meter Corneometer CM 825.

The experimental method comprises the following steps: the subjects used 6ml of the shampoo and shower gel corresponding to examples 1 to 21 and comparative examples 1 to 6, respectively, for bathing; a skin moisture tester CM 825 is adopted to respectively detect the skin moisture content of the forearm part of the human arm after 1h and 2h of bathing, and the increase rate of the 2h compared with the 1h of the back moisture content is calculated, wherein the calculation formula is (namely the skin moisture content of 2 h-the skin moisture content of 1 h)/the skin moisture content of 1h multiplied by 100%.

Because the moisture of the skin of the human body is not completely dispersed within 1 hour after the human body is bathed, the moisture content is high, and the test accuracy is low. The water after bathing is dissipated after 1h, the effect on the water content of the skin is small, and the influence degree is small, so that 1h after bathing is selected as the starting point for testing the water content of the skin.

The results of the moisturizing performance tests of examples 1-21 and comparative examples 1-6 were obtained using the above test methods, respectively.

The experimental results are as follows: the results of the moisturizing performance tests of examples 1 to 21 and comparative examples 1 to 6 are shown in Table 3

TABLE 3 results of experiments of examples 1 to 21 and comparative examples 1 to 6

As can be seen from the experimental data in Table 3, the irritation scores of examples 1 to 21 were 0.7 to 2.6, the cleansing degree was 8.1 to 9.4, the hair care effect was 7.7 to 8.8, and the moisture content increase rate was 4.09 to 5.38%; comparative examples 1 to 6 had irritation scores of 3.1 to 5.3, cleansing degrees of 4.5 to 7.3, hair care effects of 5.3 to 7.5, and moisture content growth rates of 1.31 to 3.28%. Examples 1-21 are less irritating and more clean than comparative examples 1-6, while also having better moisturizing properties.

As can be seen from the comparison of example 1 and comparative examples 1 to 3, the combination of soapwort extract and bornel is more effective in moisturizing than the combination of soapwort extract and bornel, while having less irritation and higher cleaning degree than the combination of soapwort extract and bornel. The two have better cooperation effect, and can better enhance the moisturizing performance and the cleaning strength of the shampoo and the shower gel. It can be seen from comparative example 1 and comparative examples 3 to 5 that the second surfactant and the skin conditioner, when added together, provide better moisturizing and cleansing effects and less irritation than the shampoo and body wash obtained by adding them separately.

As can be seen from comparing example 1 with examples 4 to 5, the components and weight of the skin conditioner are preferred, and the moisturizing performance of the shampoo and body wash is improved while the irritation is small; it is demonstrated that the combination of soapwort extract and Chondrus crispus helps to enhance the moisturizing properties of the shampoo compositions.

As can be seen from comparative examples 5-7, a third surfactant component is preferred to help enhance the cleaning benefits of the shampoo compositions, with less irritation. The sodium lauroamphoacetate in the third surfactant can be effectively dispersed and is dissolved with surfactants such as cocamidopropyl betaine, sorbitan laurate and the like, so that the cleaning capability of the shampoo and the shower gel is further enhanced. As is clear from comparative examples 7 to 9, decyl glucoside is preferred as the main component of the fourth surfactant, and the cleansing power of the shampoo and body wash is improved while the irritancy is reduced, and the moisturizing effect is improved; probably, when the surfactants are preferably selected, the first surfactant, the second surfactant, the third surfactant and the fourth surfactant are compounded, so that the irritation to the skin and the scalp is further reduced and the moisturizing effect is improved while the cleaning effect of the shampoo and the shower gel is improved. Comparative examples 9 to 11 show that the moisturizer consisting of trehalose and glyceryl caprylate can enhance the moisturizing performance of the shampoo composition.

As can be seen from comparative examples 11 to 13, the moisturizing performance of the shampoo and body wash was improved by adding the Phyllostachys nigra extract to the hair conditioner, and the hair care effect of the hair was improved by combining the Phyllostachys nigra extract with various surfactants, indicating that the hair care effect of the shampoo and body wash and the moisturizing performance were improved by adding the Phyllostachys nigra extract.

As can be seen from comparative examples 13 to 15, the specific formulation of the chelating agent is preferred to improve the cleansing power of the shampoo composition to some extent. Comparative examples 15 to 17 show that citric acid as a pH adjuster improves the cleansing ability and moisturizing ability of the shampoo and body wash and is less irritating. Probably because the citric acid is acidic, the irritation of the alkaline surfactant to the skin can be effectively reduced, the stratum corneum is accelerated to be renewed, and the moisturizing state of the skin is further enhanced. As is clear from comparative examples 19 to 21, the stirring speed and the stirring time in the production method are preferable, and the irritation of the shampoo and body wash can be reduced.

The present embodiment is only for explaining the present application, and it is not limited to the present application, 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 application.
