Description

Sun-screening composition with foaming function and preparation method and application thereof

Technical Field

The application relates to the technical field of cosmetics, in particular to a sun-screening composition with a foaming function, and a preparation method and application thereof.

Background

The skin is a barrier for the human body to substances such as external microorganisms, dust, chemicals, etc., so whether the skin structure is intact or not is related to whether the skin functions normally or not. The damage caused by excessive ultraviolet irradiation is often one of the important factors for skin aging, namely photoaging. Particularly, the skin is rough, the wrinkles are deepened and thickened, the structure is abnormal, the pigmentation, the vasodilation, the epidermis hyperkeratosis and the like, and even in some cases, the skin cancer with pigment can be developed. With the cognitive upgrading of consumers on sun-screening products, the sun-screening demand has gradually changed from happiness to daily rigid demand, outdoor sun-screening gradually changes to urban commute sun-screening, the sales of sun-screening related products increases year by year for several years, and the market demand increases gradually.

At present, sun protection products are continuously refined and customized according to skin, and various sun protection product forms, such as water-in-oil sun protection, pure sun protection, physical and physical combination sun protection, pure physical sun protection, oil-in-water sun protection and the like, appear. The traditional sun-proof formulation mainly comprises milk, cream and shake emulsion, and the formulation of the traditional sun-proof formulation is generally added with more grease and sun-proof agent, however, the compound mode can cause pore blockage, the skin feel is thicker, and the use experience of a user is poor. Some sun-proof products are even added with a plurality of mineral powder, which is very easy to cause burden to skin and can generate frequent mud rubbing phenomenon. Also, if not cleaned in place after use of the sunscreen, the user's skin is prone to become sensitive to irritation, even acne. While aerosol products containing nanoscale titanium dioxide and zinc oxide have been banned by the european union, since the implementation of new laws, child sun protection products do not allow new technology-made raw materials such as nanotechnology. Therefore, there is a need for a sunscreen product that has good sunscreen performance and good use experience.

The flos Rosae Rugosae contains about 300 or more volatile aromatic components dissolved in water, mainly alcohol, acid, aldehyde, ether, ester, etc., and contains phenethyl alcohol at the highest level, flavonoids, minerals, etc. The components have different functions, and can improve skin darkness, roughness, tarnish and relaxation, and also have effects of moisturizing, regulating water-oil balance, reducing skin sensitivity, and enhancing skin activity. The rose hydrosol has high-efficiency moisturizing performance, excellent whitening effect and better antioxidation effect, is widely applied to the development of cosmetics at present, and is a promising cosmetic raw material. Studies have shown that the rose hydrosol has strong antibacterial activity on bacteria. Specifically, vitamin E, carotene and phenolic compounds in the rose hydrosol have strong inhibition effect on escherichia coli, bacillus subtilis, pseudomonas aeruginosa and erwinia (reference document: [1] Zhao Bingyi, chen Qingsheng, chengzhao ] preparation of rose essential oil and rose water and skin care efficacy introduction of the rose essential oil and the rose water [ J ]. Daily chemical science, 2018,41 (11): 30-33.DOI: 10.13222/j.cnki.dc.2018.11.006).

The specific proportions and the addition amounts are shown in Table 1.

TABLE 1

Using the compositions prepared in test examples 1 to 9 as samples, foaming and skin feel in use were measured. The specific test method comprises the following steps: pressing the sun-proof mousse into a sample bottle with 80mL, and comparing the foam conditions of the products after waiting for 15 min; the body is directly pressed to the hand to perform skin feel test.

TABLE 2

Sample of	Foam condition of the product	Skin feel	pH
				Test example 1	The foam is relatively large	Light and thin skin feel and easy application	7.8
Test example 2	Foam density	The skin feel is thick and heavy, and the spreadability is slightly poor	7.9
				Test example 3	The foam is the most dense and the foam durability is the best	Light and thin skin feel and easy application	7.9
Test example 4	The foam is relatively large	Light and thin skin feel and easy application	7.0
				Test example 5	The foam is slightly bigger	Light and thin skin feel and easy application	7.1
Test example 6	The foam is dense and has good foam persistence	The skin feel is light and thin and easy to smear, and the skin has slight tingling pain feel	9.6
				Test example 7	The foam persistence is slightly worse	Light and thin skin feel and easy application	8.0
Test example 8	The foam is the most dense and the foam durability is the best	Light and thin skin feel and easy application	7.9
				Test example 9	The foam is the most dense and the foam durability is the best	Light and thin skin feel and easy application	7.8

As can be seen from the results in Table 2, the samples prepared by the methods of test examples 3, 8 and 9 have the advantages of the most dense foam, the best foam durability, light and thin skin feel and easy application, and the problem of poor use feeling of the existing sun-screening products is solved.

Wherein, since the test example 6 has a pH of 9.6 and has a tingling sensation after the human skin test, the later test has been excluded from the related tests such as SPF, PA and patch test of human body.

In the method of test example 3 in this example, triethanolamine salt formed by reacting triethanolamine with fatty acid in a specific ratio is used as foaming component, so that the foaming performance can be enriched in the presence of propellant to form a mousse-like foam, and the purpose of mild foaming can be achieved by using the weak alkalinity of the mousse-like foam. The obtained composition can be used in resident cosmetics while foaming and maintaining pH below 8.5, and can avoid adverse effect on skin of user due to excessive pH.

EXAMPLE 2 Sun protection index SPF, PA test

In this example, the sun protection factor SPF and PA were tested in test examples 1 to 9 in example 1.

The SPF value (calculated by the minimum erythema MED) is tested according to the standard of 2015 cosmetic safety technical specification, wherein the SPF value is expressed as follows:

the protection capability index for protecting ultraviolet UVA is SPF value PFA, also called PA (test index is minimum continuous blackening amount MPPD), and the formula of the test PFA value is:

the sunscreen effect of the product was tested according to the cosmetic safety Specification (2015 edition) Sun protection cosmetic sun protection index test method (human body method), and the test results are shown in Table 3 below.

Test example 2	56.0	9.5
			Test example 3	52.2	9
Test example 4	50.8	9.5
			Test example 5	52.0	8.5
Test example 6	/	/
			Test example 7	48.0	7
Test example 8	50.4	8
			Test example 9	49.0	7.4

Among them, the higher the SPF value and the PA value, the better the sunscreen effect of the composition is proved. As can be seen from Table 3, the composition prepared by the method of test example 3 has excellent sunscreen properties, SPF value of up to 52.2 and PA value of up to 9.

In addition, the difference between test example 9 and test example 3 is only whether or not rose syrup is added, and the result proves that the addition of rose syrup in the composition can effectively improve the sun-screening performance of the composition.

Thus, the composition prepared by the method of test example 3 combines excellent sunscreen properties with a better use experience and a long lasting foam.

Example 3 skin closed patch test

The compositions of test examples 1 to 9 were used as test substances for the skin closed patch test, and a blank group without using the composition was used as a negative control, and the test was carried out in 33 subjects, and finally 33 subjects were tested, wherein men 2, women 31, and ages 21 to 45.

The specific test method comprises the following steps: the selected area is not more than 50mm ² A plaque test apparatus of about 1mm depth. The test agent is added to the plaque assay in an amount of about 0.020g to about 0.025g (solid or semi-solid) or from about 0.020mL to about 0.025mL (liquid). The plaque assay with the test and negative control was applied to the forearm of the subject and removed after 24 hours. Skin reactions were observed according to the criteria of Table 4 for 30min (after the disappearance of the indentation), 24h and 48h, respectively, after removal of the plaque tester, and the observations were recorded, and the results are shown in Table 5.

Table 4 is the skin response grading criteria in the current effective specifications: cited from the "cosmetic safety Specification"/(2015 edition) chapter 2 human body patch test (national food and drug administration).

TABLE 4 skin response grading Standard for skin seal Patch test

TABLE 5 Patch results

As can be seen from the results in Table 5, none of test examples 1-5 showed allergic reactions, demonstrating that the ingredients described in this application are safe and reliable, and are suitable for use in a variety of skin conditions. The safety properties of the composition described in test example 3 are further demonstrated.

Example 4 product Performance test

The sunscreen products with foaming function obtained in test examples 1 to 9 were tested, and the specific test results are shown in Table 6 below. Specific test criteria and test results are shown in table 6.

Table 6 foaming functional sunscreens product test performance

As can be seen from analysis Table 6, the viscosity properties of the products prepared by the methods of test examples 1 to 9 in the present application are: 120-350mpa.s (standard 100-1000 mpa.s), the relative density is: 0.81-1.00 (standard is 0.80-1.10), which all meet the industry standard, and the appearance, the fragrance, the cold resistance and the heat resistance are all qualified.

In conclusion, various results show that the performance of the test example 3 is optimal, the mildness and the foam performance are realized, and the combination and the compounding of the RIVETOR and the rose hydrosol can play a role in relieving skin, and are also beneficial to improving the sun protection index and enhancing the skin tolerance.

In addition, it was found in the present application that the product prepared by the method of test example 3 was easier to clean than the existing sunscreen products after using the product. When the material is put in water, uniform dispersion can be realized, and during the use process, because of the existence of triethanolamine salt, the product can be removed with little effort or by adding other small amount of detergent.

The system added with mineral powder in the market at present is generally a water-in-oil system, is viscous and relatively low in HLB value, has better skin fit, is easy to be hidden in the gully of the skin when being adhered to the skin, is easy to cause the condition of incomplete cleaning by the same detergent, is easy to cause blocking pores and growing acnes, and is easier to destroy skin barrier and cause skin allergy after being cleaned by the detergent for many times. The product of the application effectively avoids the problems, and is safe and easier to clean.

The foregoing is merely exemplary of the present application and is not intended to limit the present application. Various modifications and changes may be made to the present application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. which are within the spirit and principles of the present application are intended to be included within the scope of the claims of the present application.
