Description

  The present invention relates to a dye removing agent, and more particularly to the effect of removing dye stains adhering to the scalp, hands, skin, etc. when using a hair dye containing an oxidation dye or an acid dye. It relates to an excellent dye removing agent.

  Conventionally, permanent hair dyes containing an oxidation dye or semi-permanent hair dyes containing an acid dye are used to dye the hair, but when using these hair dyes, the scalp near the hairline of the hair In addition, hair dye may adhere to hands, skin, etc. Various removal agents have been proposed as removal agents for removing these staining stains attached to the skin.

  For example, a dyeing removal agent containing an amphoteric surfactant, a nonionic surfactant, an aromatic alcohol and / or a monovalent lower alcohol, an inorganic alkali agent and / or an organic alkali agent has been proposed (patent document 1).

  There has also been proposed a stain remover composition containing a cationic surfactant, a reducing substance, benzyl alcohol and / or N-methylpyrrolidone (Patent Document 2).

  Furthermore, a stain remover composition containing an anionic surfactant, a reducing substance, and arginine has been proposed (Patent Document 3).

  However, these dye removing agents can not be said to be sufficiently effective in removing the stain stains adhering to the skin, and are intended only for acid dyes which are semi-permanent hair dyes. is there. In the beauty salon, it is necessary to prepare a dye removing agent for two types of permanent hair dyes and semi-permanent hair dyes, so that dyeing stains capable of removing dyeing stains attached to the skin by oxidation dyes and acid dyes can be removed. Development of a remover has been desired.

  It is an object of the present invention to provide a dye removing agent for removing stains attached to the scalp, hands, skin, etc. when using a hair dye containing an oxidation dye or an acid dye. It is.

  In view of such circumstances, the inventors of the present application have intensively found that the content of (A) fatty acid soap is 3.0 to 20.0% by weight, and the content of (B) aromatic alcohol is 1.0 to 10%. 0 wt%, (C) sulfite content of 0.1 to 5.0 wt%, (D) propylene glycol content of 5.0 to 20.0 wt%, (E) chelating agent content We have found that a decoloring agent having a 0.01% to 0.5% by weight removes dyeable stains attached by an oxidation dye and an acid dye, and completed the present invention.

  The dye remover according to the present invention effectively removes stains attached to the scalp, hands, skin, etc. when using a hair dye containing an oxidation dye or an acid dye, and further, it is applied to the skin. There was little irritation and it was excellent.

  As a fatty acid used for component (A) fatty acid soap used for this invention, a C12 or more fatty acid is preferable. For example, lauric acid, myristic acid, oleic acid, palmitic acid, stearic acid and coconut oil fatty acid etc. may be mentioned. These fatty acids can be used alone or in combination of two or more. Examples of the counter ion of the fatty acid soap include alkali metals such as sodium and potassium, and organic amines such as triethanolamine and aminomethylpropanol.

  Component (A) refers to one obtained by neutralizing a part or all of a fatty acid with a base. In the present invention, there may be free fatty acids remaining unreacted without neutralization. In the present invention, the content of the fatty acid soap refers to the total amount of the fatty acid and the base that neutralizes part to all of the fatty acid.

  The content of component (A) is 3.0 to 20.0% by weight, preferably 5.0 to 20.0% by weight. When the amount is less than 3.0% by weight, the dye removal effect can not be sufficiently obtained, the stability over time is deteriorated, and when the amount is more than 20.0% by weight, no further effect can be expected.

  Examples of the component (B) aromatic alcohol used in the present invention include benzyl alcohol, phenylethyl alcohol, cinnamic alcohol, p-methylbenzyl alcohol and phenoxyethanol. Among these, benzyl alcohol is preferable in terms of the dye removal effect. These aromatic alcohols can be used alone or in combination of two or more.

  The content of component (B) is 1.0 to 10.0% by weight, preferably 3.0 to 10.0% by weight. When the amount is less than 1.0% by weight, the dye removal effect can not be sufficiently obtained, and when the amount is more than 10.0% by weight, an aromatic alcohol-specific odor is generated and it is difficult to use it.

  Examples of the component (C) sulfite used in the present invention include sodium sulfite, potassium sulfite, ammonium sulfite and magnesium sulfite. Among these, sodium sulfite is preferable in terms of the dye removing effect. These sulfites can be used 1 type or in combination of 2 or more types.

  The content of component (C) is 0.1 to 5.0% by weight, preferably 0.5 to 5.0% by weight. If it is less than 0.1% by weight, the dye removal effect can not be sufficiently obtained, and if it is more than 5.0% by weight, no further effect can be expected.

  The content of component (D) propylene glycol used in the present invention is 5.0 to 20.0% by weight, preferably 8.0 to 20.0% by weight. If the amount is less than 5.0% by weight, the dye removal effect can not be sufficiently obtained, the stability over time deteriorates, and if the amount is more than 20.0% by weight, no further effect can be expected.

  The component (E) chelating agent used in the present invention is not particularly limited as long as it is generally used in cosmetics. For example, edetic acid (ethylenediaminetetraacetic acid (EDTA)), ethylenediaminehydroxyethyltriacetic acid, dihydroxy Ethyl ethylenediaminediacetic acid, 1,3-propanediaminetetraacetic acid, diethylenetriaminepentaacetic acid (DTPA), hydroxyethane diphosphonic acid, their derivatives and their salts. Among these, edetic acid (ethylenediaminetetraacetic acid (EDTA)) and salts thereof are preferred. These chelating agents can be used alone or in combination of two or more.

  The content of component (E) is 0.01 to 0.5% by weight, preferably 0.05 to 0.5% by weight. If it is less than 0.01% by weight, the dye removal effect can not be sufficiently obtained, and if it is more than 0.5% by weight, no further effect can be expected.

  In the dye removing agent of the present invention, in addition to the above-described components, any component used in ordinary cosmetics can be blended as long as the target effect is not impaired. For example, solvents, oils, surfactants, moisturizers, preservatives, thickeners, coloring agents, flavoring agents, anti-inflammatory agents and the like can be mentioned. However, it is not limited to these examples.

  The dye removing agent of the present invention can be produced by mixing the above-mentioned components according to a conventional method, and the method of use may be to impregnate a proper amount with cotton wool etc., apply to skin and leave for a while, and then wash away.

  Next, the present invention will be described in more detail by way of examples. However, the present invention is not limited by these. In addition, content is weight%.
