Embodiment 1

[0048] 1. The preparation of black tea extract:

[0049] Dark tea extract is prepared from black brick tea as raw material through crushing, leaching, filtration, fine filtration, reverse osmosis concentration, single-effect concentration, and spray drying. The specific preparation method is: crush the brick tea to 80 mesh particles, At a temperature of 45°C, the particles and deionized water were leached in a countercurrent extraction processor for 25 minutes according to a weight-to-volume ratio of 1:15, and filtered to obtain filtrate I and filter residue; at a temperature of 50°C, according to 1: The weight-to-volume ratio of the above-mentioned filter residue and deionized water was leached in a countercurrent extraction processor for 30 minutes, and the filtrate II was filtered, and the filtrate I and the filtrate II were combined and filtered with a 400-mesh screen to obtain the extract; The fine filtration step is as follows: the above-mentioned extract is finely filte...

Embodiment 2

[0054] 1. The preparation of black tea extract:

[0055] Dark tea extract is prepared from black brick tea as raw material through crushing, leaching, filtration, fine filtration, reverse osmosis concentration, single-effect concentration, and spray drying. The specific preparation method is: crush the brick tea to 100 mesh particles, At a temperature of 45°C, the particles and deionized water were leached in a countercurrent extraction processor for 30 minutes according to a weight-to-volume ratio of 1:20, and filtered to obtain filtrate I and filter residue; at a temperature of 50°C, according to 1: The weight-to-volume ratio of the above filter residue and deionized water was leached in a countercurrent extraction processor for 15 minutes, filtered to obtain filtrate II, and the filtrate I and filtrate II were combined and filtered with a 400-mesh screen to obtain the extract; The fine filtration step is: finely filter the above extract through an ultrafiltration membrane u...

Embodiment 3

[0060] 1. The preparation of black tea extract:

[0061] Dark tea extract is prepared from black brick tea as raw material through crushing, leaching, filtration, fine filtration, reverse osmosis concentration, single-effect concentration, and spray drying. The specific preparation method is: crush the brick tea to 60 mesh particles, At a temperature of 45°C, the particles and deionized water were leached in a countercurrent extraction processor for 15 minutes according to a weight-to-volume ratio of 1:15, and filtered to obtain filtrate I and filter residue; at a temperature of 50°C, according to 1: The weight-to-volume ratio of the above-mentioned filter residue and deionized water was extracted in a countercurrent extraction processor for 15 minutes, and the filtrate II was filtered, and the filtrate I and the filtrate II were combined and filtered with a 400-mesh screen to obtain the extract; The fine filtration step is as follows: the above extract is finely filtered thro...

Abstract

The invention relates to the field of skin care products, and particularly relates to a natural anti-aging skin care product containing black tea extracts and a preparation method thereof. The skin care product is a composite comprising an A part, a B part, a C part, a D part, an E part and an F part. Composition of each of the parts is described in the specification. The preparation method comprises a step of individually stirring the A part and the B part, and individually heating the A part and the B part to 80-85 DEG C until the A part and the B part are completely dissolved; a step of adding the A part into the B part under stirring, and adding the C part, after uniformly homogenizing and emulsifying, to obtain a mixture; a step of cooling the mixture after the mixture is uniformly homogenized; and a step of, when the temperature decreased to be lower than 45 DEG C, individually adding the D part, the E part and the F part into the mixture, and stirring and dispersing uniformly to obtain the anti-aging natural skin care product. The skin care product takes regard of anti-aging from all aspects. Functional components adopted by the skin care product are extracted from plants. The skin care product can achieve an anti-aging objective in a safe and effective manner.

Description

technical field [0001] The invention relates to the field of skin care products, in particular to a natural anti-aging skin care product containing black tea extract and a preparation method thereof. Background technique [0002] Among the skin care products currently on the market, anti-aging skin care products have increasingly become the pursuit of more and more people. Delaying skin aging has been the dream pursuit of many women since ancient times. With the advancement of science and technology, human beings have relatively clear research on aging. Among the current theories about aging, the free radical theory is more acceptable to most people. With the growth of one's own age and the influence of the external environment, especially the exposure of ultraviolet rays, free radicals in the human body will increase, which is most closely related to aging. Free radicals include reactive oxygen species (ROS) and reactive carbonyl compounds (RCS), both of which are highly re...
