Description

Method of extracting a valuable component from the rooibos, methods of producing a skin lotion, a milk lotion and an emolint using extract of rooibos extract, lotion using rooibos extract, medicinal oil cream and emollient cream cream using the same}

The present invention relates to a method for producing various cosmetics that can cure skin diseases and prevent skin aging using useful components extracted from rooibos.

In general, trees grown under the strong sun make many free radicals to protect themselves from the sun's ultraviolet rays. The material that trees make to protect themselves is what they need to protect human health.

Active oxygen is a kind of oxygen that is more easily reacted with various substances than ordinary oxygen in the air. Free radicals attach easily to substances and oxidize them and change them into other forms.

In addition to free radicals necessary for humans, such as free radicals produced by white blood cells, there are also active oxygen that are harmful to humans. Humans can't live without oxygen, but too much oxygen can cause great harm to humans. The burning of materials or the melting of metals is due to the presence of oxygen, and humans breathe oxygen into the body and use that oxygen to create energy for the body or to create materials and destroy things that are not needed. This is called metabolism of living things.

Free radicals occur in this normal metabolism. In order to protect the body from free radicals, the human body converts free radicals into oxygen or water, which are not poisonous substances. Get rid of it.

Rooibos, on the other hand, was originally consumed by South Africans as a drink of fire. Rooibos uses dried leaves and twigs of conifers and contains minerals such as magnesium, calcium, sodium, potassium, and zinc, which are extremely important as trace nutrients for the human body.

In addition, rooibos tea contains a flavonoid containing sugar as a component that shows the action of removing active oxygen. The antioxidant activity of this substance is equal to or greater than that of vitamins, and free radicals are also very strong. Flavonoids are also used in chewing gum recently because of their excellent deodorizing action.

Hereinafter, a method for preparing a rooibos extract according to the present invention will be described.

The inventors of the present invention were studying acne, atopic dermatitis and various skin diseases, and found out that rooibos is very effective in human skin diseases and has an excellent effect on suppressing skin aging and applying it to cosmetics for sensitive cosmetics. And anti-aging cosmetics.

Two methods for extracting useful components of rooibos are presented.

In the first method, finely crush 10Kg of rooibos leaves, add 100 liters of purified water, and boil at 100 ° C for 20 minutes. After filtration, the residue was concentrated under reduced pressure to obtain 20 L of concentrate. About 5 liters of purified water and 25 liters of anhydrous ethanol are added thereto, and the mixture is left to stand for 7 to 10 days in a cold place. The sunken material is filtered off and the filtrate is added to 50v / v% ethanol to obtain 50 L of rooibos extract.
