Description

Plant-based black hair dye and hair dyeing method

The present invention relates to a botanical hair dye, and particularly relates to a botanical black hair dye and a hair dyeing method using eucalyptus leaf extract or teak leaf extract as the main raw material.

The various hair dyes currently on the market mostly contain chemical substances harmful to the human body, such as p-phenylenediamine, hydrogen peroxide, ammonia, penetrants, preservatives, and harmful heavy metals, which can easily cause skin irritation, allergies, and severe cases. May induce cancer. Therefore, in recent years, more and more safe plant-based hair dyes have attracted more and more attention from consumers. For example, plants rich in polyphenols or tannic acids, such as catechins, hematoxylin, gallnut, persimmon peel, betel nut, etc., have all been studied for use in hair dyes.

For example, Chinese Patent No. 101164528A discloses a natural hair dye, which includes two agents A and B. Agent A contains catechins and organic solvents, and agent B contains ferrous salts, reduced iron powder, surfactants, and thickening agents. Agents, natural flavors, etc. Chinese Patent No. 106265333A discloses a traditional Chinese medicine hair dye, which uses persimmon skin as the main raw material, uses the phenols and tannic acid active substances rich in persimmon skin as the dye for hair dye, and contains gall, ginger, cysteine, and urea , Antioxidants, preservatives, etc. In addition, Chinese Patent No. 102397170A discloses a plant hair dye, which includes two agents A and B. Agent A contains water-soluble iron salts and excipients, and agent B contains tannic acid or hematoxylin, and contains cysteine, Alkanolamine, alkaline inorganic substance. Although the above-mentioned patent uses plant-based ingredients as raw materials, in order to improve the dyeing effect, organic solvents, ammonia, antioxidants and other chemical substances are still added. These substances are still harmful to the human body.

Therefore, there is a need to find a plant-based hair dye and a method for dyeing hair without adding any chemical substances, so as to have higher safety to the human body.

In view of this, the main purpose of the present invention is to provide a botanical black hair dye and a hair dyeing method, using plant extracts of eucalyptus leaves or teak leaves as the main raw material, which penetrates into the hair fibers in a warm environment, and then interacts with ferrous iron The ions form a complex bond to obtain the dyeing effect of natural black hair. Not only the formula is simple and safe, no chemical substances are added, and the dyeing has better durability.

Another object of the present invention is to provide a botanical black hair dye and a method for dyeing hair. Furthermore, plant extracts of eucalyptus leaves or teak leaves can be combined with Indian plants or tea plants, and the hair color can be dyed dark black. Meet the needs of hair dyeing with higher intensity colors.

In order to achieve the above objective, the present invention provides a botanical black hair dye. The botanical black hair dye is a combination of a first agent and a second agent, wherein the first agent contains a plant extract and a first thickener , The plant extract contains eucalyptus leaf extract or teak leaf extract, and the second agent contains ferrous salt and a second thickener.

In the aforementioned botanical black hair dye, the plant extract can be a liquid extracted from eucalyptus leaves or teak leaves or directly dried and ground powder from eucalyptus leaves or teak leaves; specifically, the weight percentage of the plant extracts in the first agent is 5-50%, preferably 15-50%.

In the aforementioned botanical black hair dye, the ferrous salt can be selected from ferrous sulfate, ferrous acetate, ferrous chloride or ferric oxide; specifically, the ferrous salt accounts for 0.1 to 6% by weight of the second agent.

In the aforementioned botanical black hair dye, the first thickener and the second thickener can be any thickener that increases the consistency, such as carboxymethyl cellulose, methyl cellulose, ethyl cellulose, gum arabic or Corn gum; specifically, the first thickener accounts for 1-30% by weight of the first agent, and the second thickener accounts for 1-30% by weight of the second agent.

In addition, the present invention also provides a hair dyeing method using the aforementioned botanical black hair dye. The method of dyeing hair is to first apply the first agent evenly on the hair, heat it at a temperature of 40-50°C for 30 minutes, and rinse with water. Then, apply the second agent evenly on the hair, leave it at room temperature for 20-40 minutes, rinse with water, and blow dry to obtain a hair color similar to natural black.

In the aforementioned hair dyeing method, after the step of applying the first agent to the hair and heating for 30 minutes, it further includes staying at room temperature for 2 to 3 hours, and then rinsing with water.

According to the botanical black hair dye and hair dyeing method disclosed in the present invention, the eucalyptus leaves or teak leaves and the extracts of Indysaceae or tea plants used in the first agent are all botanical ingredients, and no other solvents or chemical substances are added. It has higher safety to the human body, and the ferrous salt used in the second dose is also harmless to the human body, and it is an allowed ingredient in cosmetics and food. Furthermore, with the botanical black hair dye disclosed in the present invention, since the eucalyptus leaf or teak leaf extract can penetrate into the hair fiber and form complex bonds through ferrous ions, it is compared with the general plant hair dye that is only attached to the surface. It has better durability.
