Description
Technical Field
The invention relates to the field of cosmetics, in particular to a sunscreen cosmetic composition and application thereof in sunscreen cosmetics.

With the improvement of living standard of people, the demand of consumers for sunscreen and sunscreen products is higher and higher nowadays. The damage of ultraviolet rays to human bodies can cause the problems of skin darkness, luster reduction, pigmentation, accelerated aging, spots, wrinkles and other premature aging, and even cause some irreparable damage, such as skin cancer possibly caused by the influence of ultraviolet rays for a long time.
The chemical sunscreen agent is high-polarity and thick-skin-feel sunscreen grease, and a large amount of chemical sunscreen agent is added when a product with a high sunscreen value is manufactured, so that the stability and skin-feel experience of the product are seriously influenced. Therefore, a large amount of skin feel improving agents are added to improve the skin feel experience of the product in most cases, and the cost of the sunscreen product is improved accordingly. Secondly, the higher the amount of chemical sunscreen added, the irritation is also increased, and there are sunscreen products that use physical sunscreens in combination with chemical sunscreens to increase the sun protection index. However, most of the sunscreen products with high sun protection index, which are obtained by matching a physical sunscreen agent with a chemical sunscreen agent, on the market at present are water-in-oil systems, the sunscreen property and the water resistance of the sunscreen products are high, but the skin feel is still greasy and thick, the experience feel is poor, and the problems of whitening, dryness, pore blockage and the like frequently occur when the physical sunscreen agent is added. For sunscreen products in an oil-in-water system, the skin feel experience is better, but the sun durability and water resistance are relatively poor.
Therefore, the development of a high-index sunscreen cosmetic which can reduce the addition amount of a chemical sunscreen agent, and has excellent water resistance, sweat resistance and skin feeling is demanded in the current market.

TABLE 1
The sun protection value detection method comprises the following steps:
applying FilmQAPRO software in vitro UV detection method, adopting Gafchromic film (approximate skin tissue equivalence, precision of medical grade, average effective nuclear charge number Zeff 6.8, human skin Zeff 7.4. measuring material property change after receiving ray irradiation by charge number in the film, carrying out systematic analysis, dividing the film into two types of HD-V2 (for testing SPF value) and EBT-3 (for testing PA value)), smearing samples according to 2mg/cm2The components are weighed, evenly coated in a film, placed in a light-tight place for standing for 20min (film forming time), placed in a good light box simulating big sunlight and irradiated for 10 min. The charge number in the film is used for measuring the performance change of the material after being irradiated by rays, and then the irradiated film is analyzed and processed by FilmQAPRO software under a standard curve, and the result is shown in tables 2 and 3.
TABLE 2
TABLE 3
In-vitro UV detection results show that compared with comparative example 1, the SPF sun-screening value and the PA sun-screening value of the sun-screening sample with 1-8 wt% of VP/eicosene copolymer added in examples 1-4 are obviously improved. Wherein, the SPF value increase rate is 14-34%, and the PA value increase rate is 6-25%. Examples 5 to 6 can still reach the expected value by adding 1% to 8% of VP/eicosene copolymer when the addition ratio of the sunscreen agent is reduced. The addition of 1-8% of VP/eicosene copolymer is shown to have synergistic capability for sunscreen products.
Stability of VP/eicosene copolymer in sunscreen samples
The stability test method comprises the following steps:
1) placing the mixture in an electric heating constant temperature incubator at 40-50 ℃ for 24h, 72h, 7d, 14d and 30d, and observing the stability of the mixture after the temperature is recovered;
2) storing at-18 deg.C for 24h, 72h, 7d, 14d, 30d, and observing stability after recovering room temperature;
3) the stability was observed after long-term storage at ambient temperature (25 ℃ C.) (the stability was compared at ambient temperature for 24 hours, 72 hours, 7 days, 14 days, and 30 days).
The results are shown in tables 4 and 5, taking example 2 and comparative example 1 as examples.
TABLE 4
TABLE 5
Note that there is no abnormality in "√" and abnormality in "X". The judgment standard is that the sample is abnormal if the appearance of the material body is not separated into oil and the like after the sample is recovered to the normal temperature.
The chicken embryo irritation detection method comprises the following steps:
test samples: comparative example 1, example 4, example 5, and example 6
And (3) incubating eggs of SPF grade for 9-11 days, adding samples on chorioallantoic membranes of chicken embryos (each sample is subjected to parallel comparison detection on six eggs, and the average value is taken), observing vascular reaction, and evaluating the irritation of the samples. Evaluation criteria: see table 6, the SN/T2329-2009 eye irritation/corrosiveness test of chick embryo chorioallantoic membranes for cosmetic products, with results as in table 7.
TABLE 6
Note: larger NC value, larger irritation
TABLE 7
It can be seen that the addition of the VP/eicosene copolymer, with a reduced sunscreen ratio, has some product irritation reducing effect.
Water resistance of VP/eicosene copolymer in sunscreen samples:
equal amounts of the sunscreen samples of example 2 and comparative example 1 were spread evenly over Gafchromic film (HD-V2 for testing SPF value), and the spread was controlled at 2mg/cm2. And standing for 20min after smearing to form a film, placing the film in water flow (equal to the water flow size), flushing for 1min, naturally airing, placing the film in a dark box simulating big sunlight (testing the fluctuation of the irradiation intensity of a UV lamp in a specified range by an ultraviolet irradiator), and irradiating for 10min to perform FilmQAPRO software analysis processing. The change in sun protection index was analyzed as in table 8.
TABLE 8
The difference between the sunscreen value of example 2 after washing and the non-washing comparison is not obvious, and the sunscreen value of comparative example 1 after washing and the non-washing comparison are obviously reduced. Therefore, compared with the comparative example 1, the sunscreen sample added with a certain amount of VP/eicosene copolymer has a remarkable improvement effect on the water resistance under the same frame formula process.
Skin feel test applied in sunscreen samples:
test samples: comparative example 1, example 2, example 6, market sample 1, market sample 2
The test method comprises the following steps: the comparative example 1, example 2, example 6 and the two commercial conventional oil-in-water sunscreen products (SPF50, PA + + +) were scored on a blind scale and 30 testers performed the test to evaluate how clean and sticky the samples were, as shown in table 9.
TABLE 9
| Test set | Example 2 | Example 6 | Comparative example 1 | Market sample 1 | Market sample 2 |
| Refreshing and non-sticky | 22 | 26 | 18 | 16 | 13 |
| Greasy or sticky | 8 | 4 | 12 | 14 | 17 |
| Stimulation of | 0 | 0 | 1 | 1 | 2 |
The VP/eicosene copolymers were tested for sunscreen synergy with different chemical sunscreens the components and percentages of examples 7-12 are shown in table 10 and the results are shown in table 11.
Watch 10
TABLE 11
The addition of 1-8% of VP/eicosene copolymer has obvious synergistic effect on sun protection index in a sun protection formula, and can achieve high sun protection value, improve sun protection stability and water resistance and reduce product irritation at the same time of reducing the addition rate of a chemical sun protection agent. The synergistic capability of the VP/eicosene copolymer in different sun-screening agents is embodied in different ways, wherein the synergistic effect of the VP/eicosene copolymer and the bis-ethylhexyloxyphenol methoxyphenyl triazine sun-screening agent is remarkable in improvement effect.
