Firstly, in order to verify the stability of the skin care products prepared in the example 1 and the comparative examples 1 to 4 in the storage and use processes, the skin care products are strictly tested for the high-temperature and low-temperature storage stability according to GB/T29665-.
Test 1: 3000 r min-1Centrifuging for 30min, and observing whether the skin care product is layered;
and (3) testing 2: continuously keeping the temperature at 48 ℃ for 20 days, then recovering the room temperature and keeping the room temperature for more than 8 hours, and observing whether the skin care product has layering, solid precipitation or other inhomogeneous phenomena;
and (3) testing: continuously freezing at-25 deg.C for 20d, recovering to room temperature, maintaining for more than 8h, and observing whether the skin care product has layering, solid precipitation or other inhomogeneous phenomenon;
and (4) testing: alternately circulating for 24h at 48 deg.C and-25 deg.C for 20d, recovering to room temperature, maintaining for more than 8h, and observing whether the skin care milk has layering, solid precipitation or other inhomogeneous phenomenon.
In the above test, if the skin care product has no delamination, solids precipitation or other inhomogeneities, the stability test is passed, otherwise the stability test is failed.
After testing, the skin care products of example 1 all passed the above tests, while none of the skin care milks of comparative examples 1-4 completely passed the above tests, which indicates the high stability of the sunscreen skin care system of the present invention.
Secondly, measuring the sun protection index of the sun protection skin care emulsion
The tested samples are the sunscreen skin care products prepared in the example 1 and the comparative examples 1 to 4 of the invention. The measurement is carried out according to the relevant requirements and measurement methods of the sun protection cosmetic sun protection index (SPF value) measurement method and the sun protection cosmetic long-wave ultraviolet protection index (PFA value) measurement method in the cosmetic hygiene Specification (2007 edition) of the Ministry of health, and specific results are shown in Table 2.
TABLE 2 Sun protection index assay results
| Group of | Example 1 | Comparative example 1 | Comparative example 2 | Comparative example 3 | Comparative example 4 |
| SPF value | 27 | 6 | 7 | 7 | 8 |
| PFA value | 9 | 2 | 3 | 2 | 3 |
| PA grade | PA+++ | PA+ | PA+ | PA+ | PA+ |
Remarking:
the sun Protection factor spf (sun Protection factor) is a measure of the protective ability of a sunscreen against the ultraviolet UVB in sunlight, indicating how high or low the sunscreen can exert. It is determined based on the lowest erythemal dose of the skin. The sun protection index of the low-grade sun protection product is 2-6, the sun protection index of the medium-grade sun protection product is 6-8, the sun protection index of the high-grade sun protection product is 8-12, and the product with the SPF value within the range of 12-30 belongs to a high-strength or ultra-high-strength sun protection product.
The ultraviolet A-protection index PFA (protection Factor of UVA) refers to the ability to defend against UVA. The calculation formula is PFA = MPPD value for sun block coated skin/MPPD value for sun block not coated skin. Higher PFA values indicate longer guard times.
Sunscreen index PA (protective UVA) is a 'UVA prevention effect measuring method standard' published by the Japan cosmetic industry Association in 1996, refers to an effective degree index for preventing UVA, is the most widely adopted standard in daily commodities, and has three grades of defense effects, namely PA +, PA + + +, and PA + + +, which is added in 2013.
Therefore, the compound plant extract is prepared by compounding four raw materials of the centella extract, the asparagus extract, the lonicera confusa extract and the scutellaria baicalensis extract according to a specific proportion, has an obvious synergistic effect in the aspect of sunscreen and skin care, and achieves an unexpected technical effect.
The above-mentioned embodiments are merely preferred embodiments of the present invention, and the scope of the present invention should not be limited thereby, and those skilled in the art should not make any insubstantial changes and substitutions based on the present invention.
