Description

  The present invention relates to a hair dye composition containing dried henna leaf powder as a hair dye component.

  Even today, hair dyes that use synthetic dyes are still the mainstream, but there is little damage to hair and there are no side effects such as allergic reactions, and natural dyes that have been used since before the appearance of synthetic dyes. Hair dyes that contain plant tissue as a component are attracting attention again. Henna (Lawsonia inermis L) is a plant of the family Lamiaceae that grows naturally in North Africa, India, etc., and its leaves have long been used for hair dyeing in these regions. Today, dry leaf powder and its extract are available for hair dyeing. In general, the powder or extract is dissolved in water and brought into contact with hair, left for a while, washed, and dried. As a result, it is said that the active ingredient of henna (Lawson, that is, 2-hydroxy-1,4-naphthoquinone) penetrates into the hair and is immobilized by interaction with keratin.

  In this case, with henna leaf dry powder or its extract alone, the hair is not dyed in a darker color than reddish brown. However, when it is desired to dye the whole or part of the hair in a brown color close to black, it is necessary to use a synthetic hair dye such as paraphenylenediamine or other natural plant pigments in combination. Combined use with synthetic hair dye not only diminishes the advantages of henna, a natural product, but also has the inconvenience of requiring separate use because it is incompatible with the coloring mechanism of the combined synthetic hair dye. . Even when used in combination with natural pigments, it was difficult to obtain or to achieve the desired color.

  Liquid hair dyes containing dry powder of henna leaves, metal salts, water and optionally acids are known. This hair dye is described that an active ingredient for dyeing henna forms a complex with a metal inside the hair, and when it does not contain a metal salt, it is orange but dyes the hair brown.

JP 2003-26552 A

  Therefore, it is desired to provide a sanitary and safe hair dyeing composition capable of dyeing dark brown, which is closer to black than previously possible, using only henna powder as a pigment component. Such a hair dye composition could not be provided by the prior art.

In one aspect, the present invention comprises a first agent comprising dried henna leaf powder (hereinafter referred to as “henna powder”) and a second agent comprising a physiologically acceptable water-soluble iron (II) chelate compound. A hair dye composition is provided.
In another aspect, the present invention provides a hair dye composition comprising a first agent comprising henna powder and a second agent comprising a physiologically acceptable water-soluble iron (II) chelate compound and an extractor extract from Arcuta alba. Is provided.
When the second agent contains an extractor / aruba water extract in addition to the water-soluble iron (II) chelate compound, the second agent can be dyed more black than the additive-free one.

  Preferably, the water-soluble iron (II) chelate compound is an iron (II) salt of a hydroxycarboxylic acid, particularly iron (II) citrate or iron gluconate approved as a pharmaceutical for the treatment of anemia due to iron deficiency (II) is most preferred.

  The method of use is to apply a paste obtained by adding water to the first agent of henna powder on hair that has been washed and wiped off excess moisture with a towel, etc. Leave for ~ 60 minutes. Thereafter, the attached henna powder is washed off, excess water is wiped off with a towel or the like, the second agent is applied, and the mixture is left as it is or heated to around 40 ° C. and left for 10 to 60 minutes. Finally, rinse well with water and dry to finish. At the stage where the first agent is applied and washed away, the hair is reddish-orange, but the hair is dyed dark brown by the treatment with the second agent.

  In the present invention, a shampoo component and a conventional hair cosmetic additive can be included in the second agent used later. In a preferred embodiment, the second agent can take the form of a cream for ease of application, and this cream may be an iron (II) chelate compound and an extractor erecta alba water extract, shampoo ingredient and conventional hair. Cosmetic additives can be included.

  Cassia auriclata leaf or bark powder, which can be used in combination with henna powder to dye hair in dark red, can be included in one or both of the first agent or the second agent, preferably the second agent.

  The hair dye composition of the present invention comprises a dried henna leaf powder as a first agent, and a water-soluble iron (II) chelate compound or a water-soluble iron (II) chelate compound in a solution or cream as a second agent. Consists of erecta and alba water extract.

Ecritta alba is called Takasaburo, and is an annual compositae plant widely distributed in the tropics and subtropics. Extracted from the ground during the flowering season, the water extract of dried and dried products is used for hair care in Southeast Asia and India.
With respect to the second agent, the acid that produces a water-soluble iron (II) chelate that is not sanitary or physiologically harmless is a hydroxycarboxylic acid. Among them, gluconic acid and citric acid are substances involved in mammalian sugar metabolism pathways, and their iron (II) salts are therapeutic agents for anemia caused by iron deficiency. Therefore, iron (II) hydroxycarboxylate chelate compounds that are not concerned with safety are most preferred.

  The second agent can include conventional additives used in various hair cosmetics, shampoo ingredients, and can take the form of creams or solutions. The cream is based on cetanol and can contain nonionic surfactants. Other conventional additives can include humectants such as dipropylene glycol, thickeners and the like. A Cassia auriculata powder that is effective for dyeing into a dark red color in combination with this solution may be added and used as a paste.

  When the second agent is used as a shampoo, it is only necessary to add an iron chelate compound, or an iron chelate compound and an extractor / alba water extract to a conventional shampoo component.

  In the present invention, since the iron chelate compound is contained in the second agent to be applied later, by adjusting the usage amount of the second agent according to the usage amount of each henna powder, the dark brown color of the finished hair The degree of can be adjusted. However, even if the ratio of the iron chelate compound to the henna powder is increased beyond a certain level, the degree of blackish brown cannot be increased beyond a certain level. However, in a standard formulation, the weight ratio of henna powder: iron chelate will be in the range of 1: 0.1 to 1: 1.5. In order to increase the degree of blackish brown, an extractor / aruba extract may be used in combination.

  In all examples, the first agent is a dry henna leaf powder, so only the second agent formulation is shown.
