preparation example Construction
[0027] Wherein, the preparation method of black tea fruit extract comprises the following steps:
[0028] Step 1: First weigh the clean black tea seeds according to the weight ratio: ethanol: water = 1:2:1 and add it to the stainless steel heating reflux pot, turn on the heating, set the temperature to 98°C, and reflux cooking for 2 hours , then lower the temperature, and wait for natural cooling to about 50°C for filtration.
[0029] Step 2: Filter the above extract with 200-mesh clean gauze. After the filtration is completed, transfer the filtrate to a rotary evaporator, vacuumize, and set the temperature at 62°C for low-temperature distillation. When the filtrate is evaporated to 20% remaining, add and The first step is the same amount of butanediol, and stir evenly.
[0030] The third step: transfer the mixed solution of the second step to the rotary evaporator in batches, then vacuumize, set the temperature to 58°C, continue to evaporate the remaining ethanol, and then t...

Abstract
The invention relates to the field of skin care products, and particularly discloses a whitening composition, a preparation method and application. The whitening composition is prepared from the following components in percentage by mass: 0.5 to 5.0 percent of ribes nigrum fruit extract and 0.5 to 3.0 percent of inositol. The ribes nigrum fruit extract and the inositol are reasonably matched according to a specific ratio to obtain the whitening composition. The ribes nigrum fruit extract is rich in natural vitamin C, and can reduce the activity of tyrosinase and reduce the formation of melanin. The transdermal absorption of the natural vitamin C is limited, and the absorption degree limits the efficacy of the product. The inositol can enhance the conveying capacity of other components in a cosmetic formula, thereby enhancing the use effect of cosmetics. The inositol can promote the transdermal absorption of the ribes nigrum fruit extract and enhance the repair and anti-aging effects of the ribes nigrum fruit extract. The whitening composition can be applied to product forms of various whitening cosmetics, and has the characteristics of simple preparation method, wide application and capability of meeting market requirements.
Description
technical field [0001] The invention relates to the field of skin care products, in particular to a whitening composition, a preparation method and an application. Background technique [0002] "Whitening skin" is the eternal topic and pursuit of beauty lovers. The research and development, safety and efficacy evaluation of whitening skin care products have naturally become the focus of attention of researchers, producers, operators and consumers. The color of the skin is mainly determined by the content and distribution of skin pigments, and melanin is the most important determinant. Melanocytes in the skin produce melanin, and the melanin granules transfer to the keratinocytes through the melanocyte dendrites, and the melanin granules transferred to the keratinocytes go up to the stratum corneum along with the epidermal cells, thereby affecting the color of the skin or forming spots, and finally with the stratum corneum shed and excreted. [0003] In addition, the irrad...
