Plant extract for external use with nourishing, repairing, supple and brightening effect, head care product and preparation method thereof

Abstract

The invention discloses external plant extract with a function of nourishing, repairing, smoothing and brightening hairs. The external plant extract is prepared from the following raw materials in parts by weight: (1) weighing and uniformly mixing the raw materials in parts by weight: 1-10 parts of fructus galangae, 1-10 parts of red ginger, and 1-10 parts of sesames; (2) primary extraction: selecting plant raw materials, mixing the raw materials and a solvent I in a slurry-liquid ratio of 1: (10-100) m / m and extracting the solution for 0.5-2 hours at 40-90 DEG C; (3) secondary extraction: adding a solvent II according to the slurry-liquid ratio of 1: (10-100) m / m and extracting the solution for 0.5-2 hours at 40-90 DEG C; (4) removing the solvent I; and (5) finely filtering the solution till the solution is clarified to obtain the extract, wherein the solvent I is one of a mixture of more of ethanol, chloroform and acetone and the solvent II is one of or a mixture of more of white oil, hydrogenated polyisobutene, hydrogenated polydecene, glyceryl tricaprylate / caprate, isostearyl isostearate and plant oil.

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 nourishing, repairing, smoothing and brightening hair and a head care product prepared from the plant extract. Background technique [0002] With the development of the economy and the continuous improvement of living standards, people's attention to their own health and their requirements for appearance are also increasing. Due to the influence of factors such as the pressure of life and work, environmental pollution, perm, and hair dyeing, people's hair has problems such as dryness, dullness, and roughness. There is an urgent need for natural hair care products that are safe, non-toxic and will not cause skin allergies. [0003] At present, plant extracts are often added to head care products to increase the care effect and product safety performance. Plant extracts have many advantages as cosmetic additives, such as natur...

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.
