Description

Hair dye containing snail mucus extract and preparation method thereof {HAIR DYE CONTAINING SNAIL MUCUS EXTRACT AND PREPARATION METHOD THEROF}

The present invention relates to a hair dye for oxidative dyeing of keratin fibers.

Hair dyes are classified into permanent hair dyes, semi-permanent hair dyes, temporary hair dyes and other hair dyes depending on how long the dyed color lasts.

Permanent hair dyes are generally referred to as oxidative hair dyes. Oxidative hair dye is a principle that shows the color by the oxidation reaction of the dye using an oxidative dye. Oxidized permanent hair dyes are composed of one type, but are generally composed of a first hair dye and a second oxidant. The first agent contains an oxidative dye precursor and a coupler as a dye for coloring, and an alkali agent such as ammonia and monoethanolamine which causes the oxidation reaction by swelling the hair and promoting decomposition of hydrogen peroxide. In addition, chelates are used for the purpose of controlling the oxidation reaction of the dye using a reducing agent or an antioxidant and for blocking the metal ions. In addition, hair-conditioning agents and fragrances such as patty alcohols, surfactants or cationic polymers are included. In addition, the hydrogen peroxide contained in the oxidant, the second agent, decomposes the melanin in the hair to brighten the color of the hair and promote the oxidation of the dye.

Semi-permanent hair dyes are a principle of dyeing hair using acid dyes or basic dyes which are non-oxidizing dyes. These dyes do not undergo an oxidative polymerization reaction and are colored in themselves and are attached to the hair by ionic bonds with amino acids of the hair to dye the hair. It is relatively large in size compared to oxidized dyes and does not enter the cortex layer of the hair.

Temporary hair dye is a pigment or pearl is attached to the surface of the hair using a film forming agent to temporarily impart a coloring effect to the hair.

Other hair dyes include hair dyes using plant natural dyes such as henna, indigo or chamomile, or metallic hair dyes which dye the hair by oxidation of silver nitrate and lead acetate.

Oxidative hair dyes are generally colored by the oxidation of the first agent and the second agent, causing an oxidation polymerization reaction between the dyes contained in the first agent, and the melanin pigment in the hair is decomposed by hydrogen peroxide in the second agent. By bleaching the hair, the background color of the hair is brightened to produce a more vivid color.

These oxidative hair dyes have the advantage of excellent color persistence because they penetrate to the cortex layer of the hair due to the small size of the dye and exhibit color by oxidative polymerization reaction, but the dyeing power is slowed down depending on the hair and gradually fades due to sunlight, shampoo or sweat. Or there is a problem that the discoloration worsens the persistence of color. In addition, since the dyeing is performed by oxidation polymerization inside the hair, not only does the hair lose gloss and luster, but the hair may be severely damaged. Dye or alkaline agents and hydrogen peroxide may cause irritation of the scalp or skin. There is a problem that occurs.

An object of the present invention is to provide a hair dye having excellent dyeability and color persistence, and a method of manufacturing the same.

An object of the present invention is to provide a hair dye which has little hair damage even after dyeing and has reduced scalp irritation and a method of manufacturing the same.

The present invention provides a hair dye comprising a snail mucus extract.

The present invention provides a method for preparing a hair dye comprising mixing a first agent and a snail mucus extract at 40 to 50 ° C. and then mixing a second agent.

The hair dye of the present invention assists in the regeneration of damaged hair and enables to maintain healthy hair even after staining.

The hair dye of the present invention may contribute to regeneration of the hair root tissue by reinforcing the dermal layer of the hair root and activating the scalp tissue.

The hair dye of the present invention contributes to the moisture retention of the hair tissue and is excellent in hair moisturizing effect.

Snail mucus extract of the present invention is a natural product harmless to the human body.

According to the present invention, it is possible to prepare a hair dye having excellent dyeability and excellent color persistence even after dyeing.

The present invention includes a snail mucus extract including chondroitin and the like to help regenerate damaged hair to maintain healthy hair after staining, reinforce the dermal layer of the hair root and activate the scalp tissue to contribute to the regeneration of the hair root tissue. Not only relates to a hair dye having excellent hair moisturizing effect by contributing to the moisture retention of the hair tissue, and a method for preparing the hair dye comprising mixing a first agent including a snail mucus extract and an oxidizing dye at 40 to 50 ° C.

Hereinafter, the present invention will be described in more detail.

Hair dyes of the present invention include snail mucus extract. Snail mucus is a cell secretion that mainly contains glycoproteins and mucopolysaccharides, and plays an important role as a means of protecting the mucosa, self-recognition of cells, and information communication between cells. The snail secretes more mucus when subjected to external stimuli such as acid, salt, light, heat, etc. In order to obtain a large amount of snail mucus extract in the present invention, it is preferable to allow the snail to receive external stimulation for a certain period of time before separating the snail mucus. .

Since mucin contains mucin and mucin contains chondroitin, it is possible to protect cells, form skin tissue, maintain moisture of tissue and maintain flexibility, so that hair dye that has less hair damage after dyeing and reduced scalp irritation can be manufactured. It is possible.

In addition, snail mucus contains allantoin, glycolic acid, collagen and elastin.

Allantoin is an oxidized product of uric acid that not only heals wounds, relieves skin irritation, but also promotes the growth of healthy tissues, and functions as a chemical remover of necrotic tissues to clean the applied area. Allantoin may contribute to the regeneration of the scalp and hair root tissue damaged by the chemical reaction of the hair dye.

Glycolic acid is a kind of α-hydroxy acid, which contributes to maintaining the flexibility of the hair by hydrogen bonding with the cortex in the hair. The water contained in the hair constantly reaches equilibrium with the external moisture, so the moisturizing effect decreases over time. However, glycolic acid is not in equilibrium with the outside and thus is not affected by the external environment. Therefore, when glycolic acid is contained in the hair, the moisturizing effect can be maintained for a long time.

Collagen is a type of fibrous protein that makes up the body. It has a spiral structure like 18 kinds of amino acids. It fills the cells and forms a bond between them, giving tension to the skin and making skin elasticity, balance and swelling. And play an important role in maintaining tension. The strong adhesion of collagen intervenes in the cell-to-cell connection, and the hydration of the hydrated membrane that protects the cell membrane is protected by the high water retention of collagen, thereby inhibiting aging of the skin.

Elastin is a collagen-like protein that is more elastic than collagen. Stomach collagen and elastin, which determine the water content of the epidermal layer, can contribute to maintaining the hair roots by strengthening the elasticity of the scalp.

Meanwhile, hair is divided into cuticles (cuticles) and cortex (cortex). Cortex, which occupies most of hair, has an absolute influence on hair characteristics. Cortex is a fibrous layer composed of fibrous keratin proteins, and the physicochemical properties are determined by the way in which keratin protein molecules are bound and the amount of sulfur (S) contained in them.

Cortex is divided into a crystalline region and an amorphous region, the hard keratin (fibrous tissue) is called a crystalline region, and between the fibrous tissue is called an amorphous region where the interlayer material (CMC, cell membrane complex) is located. The interlayer is composed of soft keratin and lipids, cholesterol and its derivatives, fatty alcohols, fatty acids, ceramides, phospholipids and polysaccharides. 10.3% of the hair, 8.9% in damaged hair, showing that the amorphous regions of the interlaminar material are more susceptible to various stimuli than other parts and are easily lost.

The soft protein constituting the interlayer can be replaced by collagen and elastin so that the hair dye of the present invention including chondroitin sulfate, a kind of collagen, elastin, and polysaccharide, can be directly used as a constituent of hair when recovering damaged hair tissue due to staining. Can work.
