The dry skin with lack of water can promote the secretion of grease, so that the water-oil imbalance is caused, the condition of external oil and internal dryness is likely to occur, and the skin moisture is supplemented when the secretion of grease is reduced, so that the water-oil balance of the skin can be maintained. Therefore, it has been desired to find a cosmetic product which is excellent in effect and which can control oil and supplement water to condition the skin. However, although more cosmetics are available on the market, the performance of the cosmetics is still poor, and more cosmetics can only better meet the single demands of people, such as single water supplementing capability or single oil control capability. This is far from sufficient for increasing demands and increasing quality requirements. Therefore, in the preparation of compositions for cosmetic applications, there is an urgent need to develop an oil-controlling and water-replenishing composition combining both functions of oil control and water replenishing to solve the problems of greasiness and dryness of the skin.

(2) Test items: oxidation resistance test

Taking 0.1mL of sample solution respectively, adding 2mL of 60 mu mol/L DPPH solution, mixing uniformly, standing for 30min, adjusting zero point by using the original solvent, and measuring absorbance at 517nm to be Ai; uniformly mixing 0.1mL of absolute ethyl alcohol solvent and 2mL of DPPH solution by the same method to determine that the absorbance is Ac; the absorbance was measured for Aj by mixing 0.1mL of the sample solution with 2mL of absolute ethanol solvent. The radical scavenging rate was calculated as follows:

Clearance (%) = [1- (Ai-Aj)/Ac ] ×100%;

Wherein Aj reflects the contribution of the sample itself to absorbance; absorbance values after action of Ai sample on DPPH; ac is the absorption of DPPH itself at the measured wavelength;

The results are shown in Table 4.
