Description

Henna hair dye

Technical field

The present invention discloses a hair dye comprising a composition comprising Henna, Galla Chinensis and Pomegranate Peel as a dyeing component, and belongs to the field of cosmetics.

Background technique

Most of the hair dye products currently on the market are oxidative dyes, which are blackened by oxidation of p-phenylenediamine or benzenediols by hydrogen peroxide. A number of studies have confirmed that this oxidative dyeing agent has certain damage to the scalp, is highly toxic, and easily causes discomfort such as redness, phlegm and pain in the skin, and may cause cancer even after long-term use.

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. Henna, Galla, Shouwu, Ginseng, etc. are all used. Currently, the plants used to dye colored hair are usually Henna. , Galla Chinensis, cloves, etc., but these commonly used plant hair dye ingredients usually have a dyed color that is not pure black, usually red brown, brown black, blue black, gray black and other mixed variegated problems.

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, only the use of Henna dyed hair is more uniform. Jia Lifeng (Henna and other Arab plant dye dyeing studies, Woolen Textile Technology, 2008, 11 : 21 -24) studied the dyeing effect of Henna, which proved that after 3-10 hours, Henna dyed the wool into brown-brown Brown, but can't dye a single black. Also, when dyeing, it takes a long time and needs to be heated to 100 degrees.

Chinese Patent No. 01127328 discloses a hair dye using a treating agent, a dyeing agent, and a chelating agent, wherein iron ions are chelated with gallic acid to be colored. However, the combination of ferric ion and gallic acid is brown to purple (blue-black), which is quite different from black. Moreover, the iron sulfate solution used in the chelating agent is prone to precipitation. In actual preparation, it is necessary to take the supernatant liquid and then add a thickener to prepare a solid powder package, which is temporarily formulated into a solution or a thick paste when used, and is not suitable for ordinary consumers. Used in the home.

Chinese Patent Application No. 200810037717. 8 discloses a hair dye comprising tannic acid (gallium citrate), ferrous sulfate heptahydrate, glacial acetic acid, diethanolamine, a surfactant, etc., and the technical solution is that the problem is separate. The product obtained by the reaction of tannic acid (capric acid) with ferrous iron has an unstable dyeing effect and is easily faded after a long time.

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 the dyeing time is very long. On the other hand, the color dyed by the hair dye is not black, but grayish black, which is quite different from black, and the dyeing effect is not satisfactory.

Therefore, there is still a need in the prior art for a safe, non-toxic, easy to operate, short coloring time, and capable of dyeing black dyeing. Hair spray.
