Plant extract for external use, cosmetics and preparation method thereof with the effect of restoring skin elasticity and luster

Abstract

The invention discloses a plant extract for external use with the effect of restoring skin elasticity and luster. The plant extract for external use is prepared from the following raw materials with the following proportions by weight: (1) Weigh and mix the raw materials according to the following proportions by weight; , ginseng 1-10, peony seed oil 1-10; (2) the first extraction: mix raw materials and solvent 1 according to the material-liquid ratio of 1:10-100m / m, extract at 40-90°C for 0.5-2h; (3) The second extraction: according to the solid-liquid ratio of 1:10-100m / m, add solvent two, extract at 40-90°C for 0.5-2h; (4) remove solvent one; (5) fine filter until clarification, The extract is obtained; solvent one is a mixture of one or more of ethanol, chloroform and acetone; solvent two is white oil, hydrogenated polyisobutene, hydrogenated polydecene, caprylic / capric triglyceride, isostearic acid A mixture of one or more of isostearyl esters and vegetable oils.

Description

technical field [0001] The invention relates to a plant extract for external use, in particular to a plant extract for external use with the effect of smoothing skin, restoring skin elasticity and luster, a preparation method thereof, and a cosmetic prepared from the plant extract. Background technique [0002] The skin is the body's first barrier against external stimuli, and it is always subject to multiple challenges from inside and outside. Modern people have high work pressure, fast pace of life, staying up late, irregular diet, and increasingly serious environmental pollution, which has accelerated a series of problems such as sagging, rough, dull and dull skin. How to obtain a safe and effective plant extract that can effectively smooth the skin, restore skin elasticity and luster is a hot topic of research by those skilled in the art. [0003] Plant extracts have many advantages as cosmetic additives, such as natural ingredients of plant extracts, low irritation and...

AI Technical Summary

Problems solved by technology

At present, the main reasons for the difficulties in the application of plant extracts in the field of cosmetics are (1) The extraction efficiency is too low. Due to the characteristics of plant raw materials, the extraction effect is too low and the extraction cost is increased. Therefore, many companies prefer low-cost synthetic chemical raw materials. Replace natural plant raw materials to increase economic benefits

(2) Poor stability of plant raw material extracts

However, complex equipment, high input costs, and high extraction costs limit industrial mass production

And the extract obtained by supercritical extraction generally has poor compatibility with oil, which affects its application in oil-based cosmetics

[0015] There are many defects in the above existing methods, limited by the extraction efficiency, the preparation cost is too high, and the problems of environmental pollution caused by the discharge of organic solvents are becoming more and more prominent.
