Technical Field
The invention belongs to the technical field of cosmetics, and particularly relates to a sunscreen composition and application thereof.
Background
Ultraviolet rays contained in sunlight are classified into long-wavelength ultraviolet rays (UVA) of 320 to 400nm, medium-wavelength ultraviolet rays (UVB) of 280 to 320nm, and short-wavelength ultraviolet rays (UVC) of 200 to 280nm by the dermatology community. Ultraviolet rays of 280nm or less are absorbed by the ozone layer and do not reach the ground, but ultraviolet rays reaching the ground exert various influences on the skin of a person. Among them, UVB causes erythema or blisters on the skin, promotes melanin formation, causes pigmentation on the skin, and results in the formation of brown spots. UVA reaches the dermis of the skin, slowly changes elastic fibers in the blood vessel wall or combined tissues, so that the skin is browned, the elasticity of the skin is reduced, wrinkles are promoted to age people rapidly, and erythema reaction is promoted and even phototoxicity or photosensitive reaction is caused. Therefore, how to reduce the adverse effects of ultraviolet rays on human health by using sunscreen products has become a hot topic in the cosmetic industry in recent years.
The selection of the sunscreen agent is the core of the sunscreen cosmetic. Titanium dioxide and zinc oxide are generally adopted as sunscreen components in the current commercially available sunscreen cosmetics, the sunscreen effect is poor, the product is thick in texture, greasy in skin feel, easy to whiten, poor in skin affinity, and easy to remove or block pores.

| Example 1 | 57 |
| Example 2 | 62 |
| Example 3 | 66 |
| Example 4 | 60 |
| Example 5 | 55 |
| Example 6 | 53 |
| Example 7 | 51 |
| Comparative example 1 | 30 |
| Comparative example 2 | 45 |
| Comparative example 3 | 48 |
| Comparative example 4 | 61 |
| Commercial sunscreen cream | 29 |
From the test results in table 1, it can be seen that the sunscreen cosmetics of examples 1 to 7 of the present invention all have a large sunscreen coefficient, indicating that the sunscreen cosmetic has a high capability of protecting against ultraviolet rays, and the sunscreen effect of example 3 is the best. As can be seen from comparative examples 1 to 3, compared with the sunscreen cosmetic in example 3, the sunscreen coefficient of the sunscreen cosmetic in comparative examples 1 to 3 is significantly reduced, which indicates that the scallop polypeptide, the oat extract and the water-soluble nano cerium oxide are compounded and used at the same time, and have a synergistic effect in sunscreen. As shown in comparative example 4, the sunscreen cosmetic of the present invention has better sunscreen effect when used in combination with the film-forming agent PHYTODERMINA LIFTING.
Second, evaluation of skin feel and spreadability
The skin-feel stickiness, spreadability, and degree of whitening of the samples were evaluated in 20 subjects (aged 20 to 35 years) who had their left and right cheeks as the test areas and applied 0.1g of the sunscreen cosmetic of examples 1 to 5 and a commercial sunscreen cream (containing zinc oxide) to the test areas at different times. The results of the test are shown in Table 2, averaged over a 7 day study period.
Grading standard:
the skin feeling stickiness is 1-10 points, and the lower the point is, the stronger the stickiness is;
the spreading rate is 1-10 min, and the higher the spreading rate is, the better the spreading rate is.
The fraction of the degree of whitening is 1-10 points, and the higher the fraction is, the less whitening is likely to occur.
Table 2 evaluation results of skin feel and spreadability of sunscreen cosmetics
| Sample (I) | Tackiness of the coating | Spreadability | Degree of whitening |
| Example 1 | 9.5 | 9.9 | 9.8 |
| Example 2 | 9.8 | 9.6 | 10.0 |
| Example 3 | 9.7 | 9.8 | 10.0 |
| Example 4 | 9.7 | 9.7 | 9.9 |
| Example 5 | 9.6 | 9.8 | 9.7 |
| Example 6 | 9.3 | 9.5 | 9.7 |
| Example 7 | 9.6 | 9.4 | 9.6 |
| Commercial sunscreen cream | 5.4 | 6.7 | 5.0 |
From the evaluation results in the table 2, it can be seen that compared with the commercially available sunscreen cream, the sunscreen cosmetics in the embodiments 1 to 7 of the present invention have a good skin feel, are not sticky, and have good spreadability.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
