preparation example Construction

[0024] The preparation method of the plant composition of Examples 1 to 5 is as follows: take mulberry, wolfberry and Dijincao, mix and wash, dry, then immerse in 85% ethanol solution according to the ratio of solid to liquid of 1:10, soak for 70min; take the above mixed The solution was placed in a water bath and heated under reflux for extraction for 1.5 hours, filtered, and the filtrate was collected. The filter residue was extracted once with 8 times the amount of 85% ethanol, and the filtrate was combined twice; 8 macroporous resin columns for adsorption, first eluted with distilled water, and then eluted with 65% ethanol, collected ethanol eluate, concentrated under reduced pressure to obtain the plant composition.

[0025] Examples 1-5 The preparation method of the skin rejuvenation essence includes the following steps: mixing and stirring the moisturizing agent, chelating agent, and deionized water and heating to 80°C to dissolve them completely; after cooling down to 4...

Embodiment 1

[0038] Example 1 Plant composition in skin rejuvenation essence (self-made); 95% ethanol (Sinopharm Chemical Reagent Co., Ltd.); DPPH (Tokyo Chemical Co., Ltd., analytically pure); AB204-E electronic analytical balance (METTLE TOLEDO); UV-1600 ultraviolet spectrophotometer (METTLE TOLEDO).

[0039] DPPH appears dark purple in absolute ethanol and ethanol-water systems, and has maximum absorption at 517nm and 525nm, respectively. The free radical scavenger can make the purple fade gradually, and the content of DPPH and the scavenging ability of the reactive free radical scavenger to DPPH are measured according to the change of absorbance.

[0040] Accurately weigh 3.00 mg of DPPH, dissolve it with 95% ethanol and set the volume to 100 ml, the solubility of DPPH is 20 mg / L, take 4 ml of DPPH standard solution, place it in a test tube, add 1 ml of plant composition extract, leave it for 30 min, Absorbance A was measured at 517 nm. Determination of DPPH clearance rate according ...

Abstract

The invention discloses essence for skin rejuvenation. The essence comprises a composition of the following plants in parts by weight: 0.02-2.2 parts of a mulberry extract, 0.01-2 parts of a wolfberry extract and 0.01-2.5 parts of a humifuse euphorbia herb extract. The composition is formed by compounding the mulberry extract, the wolfberry extract and the humifuse euphorbia herb extract and is added to cosmetics, so that the antioxidant enzyme activity of organisms can be improved, excessive free radicals in a body can be eliminated, ultraviolet light can be absorbed, and the essence plays a good sunscreen role and is capable of making the skin white, moisturized, delicate and smooth after long-term use; and the composition is high in active ingredient extraction rate, and the best whitening and skin rejuvenation effects can be developed.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a skin rejuvenating essence. Background technique [0002] White, smooth, and supple skin is what people yearn for. From the composition of the skin, it can be seen that the skin's water retention and anti-oxidation are very important. The skin is divided into epidermis, dermis and subcutaneous fat. The outermost layer of the epidermis is the stratum corneum. Due to the water absorption and barrier function of the stratum corneum itself, as well as the natural moisturizing factors contained in the stratum corneum, such as amino acids, lactate and sugars, the stratum corneum maintains a certain moisture content. Amount of water to keep the skin moisturized. The appearance of the skin is related to the moisture content of the stratum corneum, which usually contains 10%-30% moisture to maintain the softness and elasticity of the skin. However, with age, the moisture content of the stratu...
