Problems solved by technology

[0004] Cosmetic compositions using lotus seeds have been studied in the past, but cosmetic compositions using lotus seeds have not been studied
In addition, the common lotus extract does not separate the flowers, stems, roots and other parts, but extracts them as a whole, so the extraction effect is not good, and other substances other than lotus need to be added to supplement the effect, so the preparation process is complicated

preparation example Construction

[0019] The preparation method of the lotus seed extract used in the present invention is not particularly limited, and the extract includes: extracts extracted from lotus seeds, decocted, or concentrated solutions obtained by concentrating part or all of the extracts, or dried and prepared from the concentrated solutions The original solution, as well as the chemical substance itself that exerts the main effect contained in the extract.

[0020] Specifically, the lotus seed extract is preferably extracted using a subcritical water extraction method (Subcritical Water Extraction). In the supercritical extraction method used in the past, the density of the supercritical fluid is similar to that of a liquid, and its viscosity and diffusion coefficient are similar to those of a gas. Therefore, when the supercritical fluid is used as an extraction solvent, it can easily penetrate into the microscopic pores of the plant body, obtain an appropriate molecular density, surround the mol...

Embodiment 1

[0031] Embodiment 1 germinated lotus seed extract

[0032] The lotus seeds in the germinated state are put into a solvent of 70% by weight of purified water and 30% by weight of ethanol, and placed at 25° C. for 6 hours to extract active ingredients. After extraction, filter once in a filter with 3 μm pores and once in a filter with 1 μm pores to eliminate foreign matter, and finally use a sterilizing filter to eliminate microorganisms to obtain germinated lotus seed extract.

Embodiment 2

[0033] Embodiment 2 subcritical lotus seed extract

[0034] Use a subcritical extraction device to extract active ingredients from ungerminated lotus seeds at 40°C and 20MPa for 4 hours. After extraction, filter once in a filter with 1.2 μm pores, once in a filter with 0.45 μm pores, and once in a filter with 0.2 μm pores to eliminate foreign matter and microorganisms to obtain subcritical lotus seed extract .

Abstract

The invention relates to a skin external use composition using lotus seed extract as effective constituents and specifically relates to a skin external use composition which uses sprout lotus seed extract as effective constituents and which is capable of providing substantial skin moisture preservation improving effects.

Description

technical field [0001] The present invention relates to an external skin preparation composition containing lotus seed extract, and more particularly, to an external skin preparation composition containing lotus seed extract and capable of providing a remarkable skin moisturizing effect. Background technique [0002] Recently, in order to solve the side effects of various chemical substances on the skin and to exert the skin moisturizing effect, a large number of skin external preparation compositions such as cosmetics containing natural products have been developed. For this reason, the present inventors have studied various natural products unknown to the public as skin external preparations to study the possibility of their application. [0003] Lian received attention. Lotus root, stem, leaf, fruit and many other parts have been used as food or Chinese medicine for a long time, so it is a certified safe plant, and its price is very low, so it has advantages as cosmetics...
