Description
Technical Field
The invention discloses a sunscreen cosmetic. More specifically, the invention relates to a high-power oil-in-water sunscreen cosmetic, belonging to the technical field of cosmetics.
Background
The skin is exposed to ultraviolet radiation for a long time, and then is subjected to erythema, edema, thickening, pigmentation, sunburn of cells, immunosuppressive photoaging and tumorigenesis. The sun-screening product is used for reducing the damage of ultraviolet rays to the skin, and becomes a relatively accepted skin care mode.
For emulsion type sunscreen products, two general types of emulsion systems can be distinguished: oil-in-water type, water-in-oil type. The water-in-oil sunscreen product usually has thick and sticky skin feel due to high-content oil and high-molecular-weight main emulsifier in the external phase, and the experience of consumers is not good when the sunscreen product is used in summer. The oil-in-water type emulsion has a great advantage in summer due to its water-moist feeling. However, most oil-in-water emulsion cosmetics have poor water resistance as compared with water-in-oil emulsion products. Particularly in summer, people easily sweat or frequently soak in water for swimming, and the sun-proof product has more chance of being exposed to water. Oil-in-water type cosmetics are more likely to cause the loss of the ultraviolet ray protection agent due to poor water resistance, thereby reducing the ultraviolet ray protection function of sunscreen products. Therefore, it has been a subject of research to maintain excellent water resistance as an oil-in-water emulsion cosmetic while maintaining its ideal feeling of use.
Chinese patent CN105188648A proposes that when a salt of a higher fatty acid component containing a liquid higher fatty acid is used as a surfactant and the pH of the system is controlled to be in the range of 7.1 to 9.5, a cosmetic composition which is not irritating when applied to the skin, has high water resistance, is excellent in feel and storage stability, and is easy to wash with soap can be obtained.
Chinese patent CN107951734A discloses a sunscreen additive consisting of C20-22 alcohol phosphate and C20-22 alcohol, and an O/W type sunscreen using the sunscreen additive, which has light, thin and soft use feel and good durability, and avoids the defects of poor water resistance, low skin-sticking property and the like of the conventional O/W type sunscreen.
Chinese patent CN105934232A proposes an aqueous dispersion containing a hydrophobic organic surface-treated fine inorganic powder in a blending amount of 30 mass% or more, and containing a polyol, water and a nonionic surfactant, and by blending the dispersion in a cosmetic, a cosmetic having a stable O/W preparation having an ultraviolet shielding effect, a good touch feeling, sweat resistance, water resistance and water resistance can be provided.
However, in the research and development of these oil-in-water emulsion cosmetics, most of the research and development focuses on improving water resistance, and the research on improving both water resistance and sun protection index is less. Therefore, it is very important to develop a sunscreen cosmetic having a good touch, a high sun protection index and strong water resistance.
In terms of increasing the sun protection factor, the simplest and most effective method is to increase the amount of sunscreen added. However, most sunscreens are irritant and light sensitive substances, and the more concentrated the sunscreen is, the more potential it is to cause allergy, and the more negative effects are caused, and the excessive addition of sunscreen is prohibited by national regulations.
Therefore, a method of selecting oils and fats having high polarity and good spreadability and dispersibility by using a sunscreen agent in combination is also a method of increasing the sun protection index.

In order to better prove the technical scheme provided by the application, the following provides a detection test of the technical scheme provided by the application:
1. test of Water resistance
In the invention, the components such as the organic silicon film-forming agent, the film-forming auxiliary agent, the emollient and the like are added into the composition in a certain content, so that the sunscreen cosmetic has a better waterproof effect. Thus, the water-proof test was performed for examples 1 to 7 and comparative examples 1 to 6, respectively.
Generally, the water resistance test is mainly for oil-in-water type sunscreen cosmetics. The compositions of examples 1 to 7 and comparative examples 1 to 6 were drawn by a film drawing machine into uniform films of 60 μm thickness on a drawn film board of BYK. After drying, contact angle measurements were performed using a DSA 25 contact angle analyzer to assess the hydrophobic ability of the different compositions. Deionized water is used as contact liquid in the experiment, at least 3 points of one sample are taken for contact angle test, and the test result is averaged. The contact angle data is the data of 1s after the drop, the drop volume is 3.8 muL, and the experimental temperature is room temperature.
The results of the water repellency test of the compositions of examples 1 to 7 and comparative examples 1 to 6 are shown in Table 3. Generally, the larger the static contact angle, the more excellent the hydrophobic property of the waterproof film is.
TABLE 3 Water repellency test results
From the experimental results in table 3, it can be seen that when the composition is added with the components such as the organosilicon film-forming agent, the film-forming assistant, the emollient, the nonionic surfactant and the like at the same time, and the components are in a certain content range, the static contact angle of the sunscreen cosmetic of the invention is above 66 °. When relevant components such as organosilicon film forming agents or film forming aids are absent from the composition or the content of each relevant component is not in a proper range, the static contact angle value is low. Therefore, the invention can greatly improve the waterproof performance of the sunscreen cosmetic by reasonably combining various components and selecting proper addition proportion.
2. Evaluation of sunscreen Effect
Main apparatus and reagents: the carrier to which the sunscreen product is applied is a PMMA plate (HD2, Schonberg company, germany); the instrument for testing SPF values was a uv-vis spectrophotometer Cary300(Varian, usa) and a built-in integrating sphere device (Labsphere, usa); analytical balance XS205(Mettler Toledo, Switzerland); antistatic disposable finger cuffs (Duracots, japan); a disposable 1mL sterile syringe (Shanghai Kangdelai).
Reagent: examples 1-7 sunscreen formulations and the formulations of comparative examples 1-6.
The test method comprises the following steps: in the testing process, a 1mL disposable syringe is used for sucking a sample and adding the sample on a PMMA plate, the sample is dripped on the plate (0.75mg/cm) in enough uniform size in a dripping mode, then a finger cot is worn for smearing, smearing time is not too long but the uniformity of the smeared sample is guaranteed at best, and the sample adding amount and the residual amount of the smeared sample are accurately controlled by an analytical balance. The carrier coated with the sunscreen sample is horizontally placed at a dark direct light place at normal temperature, dried and balanced for 20min, then placed in a Cary300 with a built-in Labsphere integrating sphere for testing, each carrier plate tests 12 different positions, and each position respectively performs 290-400 nm transmittance scanning. The SPF of the sample was then calculated from the scan data for the 12 positions. The calculation formula of the SPF is:
wherein E (λ) — the erythema effect coefficient (CIE-1987);
i (λ) — the irradiation intensity of the UV light source of the instrument for SPF testing;
A0(λ) — the average monochromatic absorbance of each sample plate before UV irradiation;
d (λ) — step size of wavelength (1 nm).
And (3) testing results:
table 4 SPF test results of examples and comparative examples
| Group of | SPF for PMMA Board test |
| Example 1 | 42.6 |
| Example 2 | 43.7 |
| Example 3 | 45.2 |
| Example 4 | 51.5 |
| Example 5 | 52.7 |
| Example 6 | 51.9 |
| Example 7 | 52.3 |
| Comparative example 1 | 20.3 |
| Comparative example 2 | 22.9 |
| Comparative example 3 | 17.7 |
| Comparative example 4 | 19.4 |
| Comparative example 5 | 17.5 |
| Comparative example 6 | 23.4 |
From the test results in table 4, it can be seen that the sunscreen cosmetic of the present invention can be reasonably combined with uv ray protection agents, silicone film-forming agents, film-forming aids, emollients, nonionic surfactants, etc., to obtain sunscreen cosmetic with high SPF value. When the organosilicon film forming agent is not added in the composition (such as comparative example 1), or the content of the added film forming aid is small (such as comparative example 2), the use of the hydrophilic ultraviolet scattering agent (comparative example 3), the improper proportion of the scattering agent and the absorbing agent in the ultraviolet ray defense agent and the like can cause the poor sunscreen effect of the product. In addition, it can be seen from the results of the examples of the present invention that when the liquid higher fatty acid is used in the emollient of the present invention, the improvement of the sun protection index of the whole formula is greatly facilitated.
3. Skin feel test
Skin feel evaluation was performed on the high-power oil-in-water sunscreen cosmetics obtained in examples 1 to 7 and the cosmetics of comparative examples 1 to 6 according to the sensory analysis method in the cosmetics industry.
(1) Evaluation items: spreadability, freshness, absorbency, mildness, overall effect;
(2) a grading system: the score is 1-10, and the higher the score is, the stronger the characteristic of the project index is;
(3) the experimental scheme is as follows: 60 trained evaluators were selected, with an average of 12 groups of 5. Female, age 25-35; the preparation is carried out in a constant temperature independent environment (22 +/-1 ℃), the relative humidity is 50 +/-5%, and the preparation is carried out after the rest is carried out for 1 h;
(4) the evaluation results are shown in Table 5:
table 5 skin feel test results
As can be seen from Table 5, the sunscreen cosmetic prepared according to the present invention is superior to comparative examples 1 to 6 in terms of spreadability, freshness, absorption, mildness and overall effect in use; the formula of the invention is better in use effect.
In conclusion, the invention provides the high-power oil-in-water sunscreen cosmetic, the organosilicon film forming agent is used to combine the components such as the film auxiliary agent, the ultraviolet ray defending agent combined by the ultraviolet ray absorbent and the ultraviolet ray scattering agent, and the like, and the waterproof performance of the oil-in-water sunscreen product is synergistically enhanced through a large amount of experiments, scientific and reasonable proportioning, so that the sunscreen index is improved on the premise of reducing the usage amount of the chemical sunscreen agent as much as possible. Meanwhile, the sun-screening agent has excellent touch under the condition of high content of the ultraviolet scattering agent, and the sun-screening formula is milder and has a larger application prospect.
