Description
Technical Field
The invention belongs to the technical field of beauty and skin care, and particularly relates to a preparation method of a natural plant extract for a whitening skin care product.
Background
At present, with the continuous improvement of living standard, people pay more and more attention to their skin conditions, the scale of the skin care product industry is continuously increased, as the industry is continuously developed, more enterprises pay more attention to the requirements of consumers and the individual characteristics of the consumers, and people in China are already in the stage of widely using skin care products, so that the market scale of the skin care product industry is continuously enlarged, the quality requirements of the skin care products for people are higher and higher, especially in recent years, natural extracted active ingredients such as whitening and moisturizing are more and more favored by the consumers, and the natural extract is sought as a raw material of the skin care products to become a high-end beauty and skin care product.
However, a single plant extract is added into the traditional beauty skin care product, and because the quality of the plant extracts in the current market is uneven, and most plant raw materials contain effective components such as polysaccharide, and the drying is difficult, a certain proportion of auxiliary materials are added into the prepared extracts, and meanwhile, the same natural active component comes from different species of raw materials, so that the reliable source of the effective components in the beauty skin care product cannot be ensured, and the natural extraction is really realized without adding. Therefore, a new natural plant extract which is free of additives and can be used as a whitening skin care product and a preparation method thereof are needed.
Through the above analysis, the problems and defects of the prior art are as follows:
(1) the traditional beauty skin care product is added with a single plant extract, and the plant extracts in the current market have different quality, and most plant raw materials contain effective components such as polysaccharide mixture and the like, so the drying is difficult.
(2) The traditional beauty skin care product can be added with a certain proportion of auxiliary materials when preparing the extract, and simultaneously the same natural active ingredient comes from different species of raw materials, so that the reliable source of the active ingredients in the beauty skin care product can not be ensured, and the natural extraction can be really realized without adding.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a preparation method of a natural plant extract for a whitening skin care product, and particularly relates to a compound extract for beautifying and protecting skin and a preparation method thereof.
The invention is realized in such a way that the preparation method of the natural plant extract for the whitening skin care product comprises the following steps:
mixing folium cortex eucommiae, scutellaria baicalensis, leonurus and centella asiatica, washing with purified water, and drying in the air;
step two, extracting the mixed raw materials by using ethanol to obtain a compound extracting solution;
step three, decompressing and concentrating the compound extracting solution to obtain alcohol-free extract;
step four, preserving the heat of the alcohol-free extract, adding purified water while stirring, heating, preserving the heat, standing at room temperature, standing, filtering by adopting diatomite, washing a filter cake by a small amount of purified water, and collecting filtrate;
step five, after the filtrate is decompressed and concentrated, performing water bath reaction in a four-mouth bottle; after the reaction is finished, adding propylene glycol for heat preservation without cooling the extract, and stirring while adding to obtain a reaction solution;
and step six, cooling the reaction liquid to room temperature, and filtering by adopting medium-speed filter paper to obtain the beauty and skin care extract.
Further, in the first step, the eucommia ulmoides leaves, the scutellaria baicalensis, the motherwort herb and the centella asiatica are mixed according to the ratio of 5:2:1: 2.
Further, in step two, the extracting includes:
extracting with 70% ethanol at 70 + -2 deg.C twice, 8 times and 7 times of solvent, each for 3 hr.
Further, in the third step, the compound extracting solution is decompressed and concentrated at the temperature of 65 ℃ until the sugar degree is more than 40 percent and the water content is 60-65 percent.
Further, in the fourth step, the alcohol-free extract is kept at 60 +/-2 ℃, 4 times of purified water is added while the extract is hot, the temperature is raised until the temperature of the system reaches 60 +/-2 ℃, the extract is kept at the temperature for 1 hour, and then the extract is placed at the room temperature and kept still for 12 hours.
Further, in the fifth step, the filtrate is concentrated under reduced pressure at 65 ℃ until the sugar degree is 40% and the water content is 60-65%.
Further, in the fifth step, reacting in a four-mouth bottle, heating to 85 ℃ in a water bath, preserving the temperature for 5 hours, recording the temperature of the extract every 1 hour, and ensuring that the temperature of the extract is 85 +/-2 ℃; adding propylene glycol, keeping the temperature for 5-10 min, controlling the solid content to be 20% of the propylene glycol, and stirring while adding.
Further, in the sixth step, the room temperature is 25-35 ℃.
Further, in the sixth step, the solid content of the beauty and skin care extract is strictly controlled to be 20%.
The invention also aims to provide the natural plant extract for the whitening skin care product, which is prepared by applying the preparation method of the natural plant extract for the whitening skin care product, wherein the natural plant extract for the whitening skin care product is prepared from folium cortex eucommiae, scutellaria baicalensis, leonurus and centella asiatica in a ratio of 5:2:1: 2.
