Problems solved by technology

[0016] However, such a whitening agent and anti-aging agent have not been provided so far. It should be a natural product that is easy to obtain, cheap and safe, and will not affect the quality of the added object in terms of taste, smell, and sense of use. To avoid adverse effects, it can be widely used in skin cosmetics

manufacture example 1

[0092] - Manufacture of water extracts of each plant -

[0093] To the pulverized material of each plant shown in Table 1 below, 10 times the amount of water by weight was added, heated at 80° C. for 2 hours, and filtered. The same amount of water was added to the residue, heated at 80° C. for 2 hours, and filtered. The obtained filtrate was concentrated and freeze-dried to obtain a water extract (freeze-dried product) of each plant.

[0094] Table 1 shows the "extraction rate" of the obtained water extract of each plant.

[0098] - Manufacture of 50% by weight ethanol extract of each plant -

[0099] 50% by weight of ethanol was added in a 10-fold amount by weight to the ground material of each plant shown in Table 2 below, heated at 80° C. for 2 hours, and filtered. The same amount of 50% by weight ethanol was added to the residue, heated at 80° C. for 2 hours, and filtered. The obtained liquid was concentrated and freeze-dried to obtain a 50% by weight ethanol extract (freeze-dried product) of each plant.

[0105] - Manufacture of 80% by weight ethanol extract of each plant -

[0106] 80% by weight of ethanol was added in a 10-fold amount (weight ratio) to the ground material of each plant shown in Table 3 below, heated at 80° C. for 2 hours, and filtered. The same amount of 80% by weight ethanol was added to the residue, heated at 80° C. for 2 hours, and filtered. The obtained filtrate was concentrated and freeze-dried to obtain an 80% by weight ethanol extract (freeze-dried product) of each plant.

Abstract

A skin-whitening agent or an anti-aging agent comprising at least one member selected from an extract from Myrica cerifera, an extract from Iris vesicolor, an extract from Piper kadzura, an extract from Primula veris, an extract from Aloysia triphylla, an extract from Agrimonia pilosa, an extract from Vaccinium spp., an extract from Apium graveolens, an extract from Tamarix tenuissima and an extract from Passiflora edulis.

Description

technical field [0001] The present invention relates to a whitening agent and an antiaging agent, and to a skin cosmetic containing at least one of the whitening agent and the antiaging agent. Background technique [0002] The epidermis and dermis of the skin are composed of epidermal cells, skin fibroblasts, and extracellular matrices such as collagen and elastin that are distributed outside these cells and support the skin structure. In young skin, since the interaction of these skin tissues is maintained in balance, water retention, softness, elasticity, etc. can be ensured, and the skin will look firm, shiny, and maintain a supple state. [0003] However, if the skin is affected by external factors such as ultraviolet (UVA, UVB) radiation, extremely dry air, excessive skin cleansing, contact with hydrogen peroxide, or ages, the production of extracellular matrix such as collagen and elastin will be reduced, and at the same time cause a reduction in elasticity due to cro...
