Description

Composition for dyeing brown hair

The invention discloses a composition for dyeing hair, which comprises a haina, a hazelnut and a pomegranate peel, which can dye brown hair. Further, the present invention discloses a hair dye based on the composition, which belongs to the field of cosmetics.

Background technique

At present, hair dyes on the market, the mainstream products are oxidative hair dyes, which are dyed by oxidation of a certain concentration of hydrogen peroxide with p-phenylenediamine and benzenediol, but this oxidative hair dye has certain damage to the scalp. , toxic,

Say

It is easy to cause redness, tingling and other discomfort in the skin. The long-term use has the risk of carcinogenicity.

In order to avoid the side effects of chemical hair dyes, researchers have generally studied the types of plants that can be used for hair dyeing, Galla Chinensis,

Book

Shouwu, ginseng, etc. have been applied. However, these ingredients are usually also used to dye black hair, and other colors, such as brown hair, have not been studied in depth. Plants currently used for dyeing colored hair on the market are usually Henna, Galla, Clove, and the like.

Henna, also known as henna, Henna, H. chinensis Henna (or also known as Japanese genus), about 1 m high, flowers are very fragrant, white, pink or purple, etc., Henna is A natural dye, its leaves, flowers or whole plants can be used as raw materials for hair dyes due to its natural non-toxic properties.

Zhao Qian (natural ingredients for hair dyes, Journal of Daily Chemical Science, 2008, 31 (8 ): 45-48 ) discloses that Henna contains 2-hydroxy-1,4-naphthoquinone, which can dye hair into maroon or red. brown. However, the color of the dyed hair is only a single color, and the dyed color is reddish. Jia Lifeng (Henna and other Arab plant dye dyeing research, Woolen Textile Technology, 2008, 11 : 21 -24) studied the dyeing effect of Henna, and proved that after 3-10 hours, Henna can dye the wool into brown one. Brown. However, when dyeing, it takes a long time and needs to be heated to 100 degrees.

Chinese patent application 200510029176 discloses a plant hair dye comprising a dyeing agent (guar gum, polyquaternium, cellulose, etc.), a chelating agent (water-soluble iron salt), and a combination of three kinds of pomegranate peels. The dye is more complicated to use and takes a long time to dye. On the other hand, the dye dyes the color closer to dark brown and grayish black, which is significantly different from brown and cannot be used for dyeing brown.

Therefore, there is still a lack of a plant-type hair dye which can be used for dyeing brown hair in the prior art.

Summary of the invention

Through extensive experimental research and staining analysis, the applicant unexpectedly discovered that the hair dyed by the combination of Henna, scorpion and pomegranate skin as a hair dye component and the water-soluble salt of iron ions is pure brown. , not red, brown, brown, etc., and the fixing effect is good, the dyeing effect is stable, and it is not easy to discolor. Based on this finding, the applicant has completed the present invention.

The invention discloses a composition for hair dyeing, comprising a first agent and a second agent, wherein the first agent is a dye agent, including sea Na, hazelnut and pomegranate peel, the second dose contains a chelating agent, wherein the first dose of Henna is 1-20 parts by weight, the hazelnut parts by weight is 1-20, and the pomegranate peel is 1-20 parts by weight. The chelating agent is a water soluble salt of iron ions.
