Description

A kind of whitening and anti-wrinkle lady ointment and its preparation method

technical field

The present application relates to the field of cosmetics, more specifically, it relates to a whitening and anti-wrinkle lady cream and a preparation method thereof.

Background technique

For a long time, whitening and freckle removal has been a topic of keen concern to people. Pigmentation has long been a major problem that plagues human skin, especially as the age increases, the probability of skin pigmentation also increases significantly. The main reason for the formation of pigmentation is that there are many pigment cells distributed in the lower layer of the human epidermis. The pigmentation cells are catalyzed and oxidized by tyrosinase in the body to form melanin. Therefore, in order to achieve the effect of whitening and removing freckles, it is often necessary to add ingredients with whitening and removing freckle effects in skin care products.

But, along with the quickening of people's life rhythm, people are more and more higher to the requirement of skin care product, not only want skin care product to have the effect of whitening and freckle removal, also need to have certain anti-wrinkle effect. Yet the effect of present skin care product is all relatively single, can not satisfy people's different demands to skin care product simultaneously. Therefore, there is still room for improvement.

Experiment 1 Inhibition rate of elastase

The inhibition rate of elastase was determined by spectrophotometry. Congo red-elastin is used as the substrate. After the elastin is decomposed by the enzyme, the Congo red will fall off. The content of the Congo red in the solution is measured to characterize the enzyme activity. Dissolve the noble lady paste prepared in Examples 1-7 and Comparative Examples 1-4 in water respectively, and respectively configure a test solution with a concentration of 6 mg/mL; add Congo red-elastin and boric acid buffer solution into the Erlenmeyer flask, Place in a 37°C water bath to preheat for 10 minutes, then add the above test solution and 0.2 mg/mL elastase solution, see Table 8 for details.

Table 8

The above reaction system was placed in a constant temperature water bath shaker at 37°C and shaken for 20 minutes, and immediately added 5.0 mL of pH 6.0 phosphate buffer solution to mix to terminate the reaction, and centrifuged at 5000 r/min for 15 minutes. Accurately draw 2.0mL of the supernatant, add 2.0mL of the equal volume mixture of pH8.8 borate buffer and pH6.0 phosphate buffer, shake well and measure its absorbance at 495nm.
