Abstract

PURPOSE:To obtain a hair dyeing agent composition having excellent finish, having extremely low damage of hair, by blending hair dyeing agent components with a specific photo element. CONSTITUTION:Ordinary hair dyeing agent components are blended with 0.00001-1wt.% at least one selected from photo elements 101, 201, 301 and 401 and prepared to give the objective substance. The substance can be processed into a form such as solution, cream, gel, paste, powder, solid, aerosol, aerosol foam, etc. Permanent hair dyeing agents such as oxidative hair dyeing agent and vegetable hair dyeing agent or semipermanent hair dyeing agents such as color lotion may be cited as the hair dyeing agent and a two-pack type oxidation hair dyeing agent comprising a first agent consisting essentially of oxidation dye intermediate and a second agent consisting essentially of an oxidizing agent is generally used. By adding a specific photo element, damage of hair can be prevented and the hair of natural color having moisture and mellowness can be obtained without damaging dyeing effects as a hair dyeing agent.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a hair dye composition, and more specifically, to a hair dye composition that has excellent color finish and causes extremely little damage to the hair. be.

(Prior Art and its Problems) Conventionally, two-part oxidative hair dyes have been widely used as hair dyes, consisting of a first part containing an oxidative dye intermediate and a second part containing an oxidizing agent. This hair dye permeates a colorless, low-molecular-weight oxidative dye intermediate into the hair and causes oxidative polymerization in the hair to produce a pigment and dye the hair.

However, although this hair dye is very convenient because it can dye hair in various tones according to the customer's wishes and has excellent hair dyeing power, it does not damage the hair during the hair dyeing process. However, as a result, the hair loses its moisture and mellowness, resulting in an unnatural color that gives third parties a sense of discomfort, and also has the disadvantage that it is difficult to comb and the hair loses its suppleness.

Therefore, in the past, various compounding agents have been researched to improve these drawbacks, but in the case of compounding agents that can sufficiently prevent hair damage, it is possible to use a compounding agent that exhibits robust hair dyeing power as a hair dye. There are many things that inhibit the effectiveness of the hair dye itself.
Further improvements are desired.

(Problems to be solved by the invention and means for solving the problem) In view of the above-mentioned circumstances, the inventor of the present invention has devised a method for dyeing hair that does not adversely affect the dyeing power of the hair, prevents damage to the hair, and provides moisture and mellowness to the hair after dyeing. As a result of intensive research aimed at obtaining a hair dye composition that gives a smooth and natural finish, we discovered that the object of the present invention could be achieved by incorporating a certain compound, and completed the present invention. I came to the conclusion.

That is, the gist of the present invention is that Photosensitive Element No. 101, Photosensitive Element No. 2
The present invention relates to a hair dye composition characterized in that it contains at least one compound selected from Photosensor No. 01, Photosensor No. 301, and Photosensor No. 401.

Hereinafter, the configuration of the present invention will be explained in detail.

Examples of hair dyes targeted by the present invention include permanent hair dyes such as oxidative hair dyes and vegetable hair dyes, and semi-permanent hair dyes such as color lotions. A two-part oxidative hair dye is generally used, which consists of a first part containing an intermediate as a main ingredient and a second part containing an oxidizing agent as a main ingredient. The hair dye may be in various forms, such as liquid, cream, gel, paste, powder, solid, aerosol, or aerosol foam.

The oxidation dye intermediate that is a component of the first agent in a two-component oxidative hair dye usually includes phenylenediamines, aminophenols, tolylenediamines, aminonitrophenols, diphenylamines, and diaminophenylamines. , N-phenylphenylenediamines, diaminopyridines, and salts thereof. The blending amount thereof is, for example, about 0.01 to 10% by weight based on the total weight of the first agent. Further, as a coupler, resorcinol, pyrogallol, catechol, meta-lactinophenol, meta-phenylenediamine, etc. can be blended. In addition, "Hair dye raw material standards"
(Revised Third Board, published in May 1985, published by Japan Hair Color Industry Association, Hair Dye Association) may also be used. Furthermore, surfactants such as polyoxyethylene alkyl ether and polyoxyethylene alkylamine fatty acid amide, humectants such as glycerin and propylene glycol, oily components such as lanolin, squalane, and liquid paraffin, and stabilizers such as sulfites and ascorbic acid. , a thickener such as carboxymethyl cellulose, an alkali agent such as aqueous ammonia or alkanolamine, a higher alcohol, a fragrance, etc., may be appropriately blended as required. On the other hand, the second agent usually contains oxidizing agents such as hydrogen peroxide and flavor peroxide, stabilizers such as zenacetin and EDTA, fats and oils such as paraffin, higher alcohols, surfactants, and acids. When using Uko's hair dye, which can contain a 0-day conditioner, fragrance, etc., as needed, mix the first and second parts and apply it to the hair just before the hair dyeing process. Apply.

In the case of semi-permanent hair dyes, they contain acid dyes or basic dyes, dyeing aids such as lower alkylene carbonate, N-alkylpyrrolidone, benzyl alcohol, levulinic acid, thickeners, lower alcohols, acids, etc. can be appropriately blended as needed.

In the present invention, it is an essential requirement that at least one compound selected from the above-mentioned hair dye be blended with the above-mentioned hair dye. be.

In short, in the present invention, by incorporating a specific photosensitizer, hair can be dyed while preventing damage to the hair, and moreover, it is possible to achieve a durable and excellent dyed finish.

All of the photosensitive elements specified in the present invention are known as additives for cosmetics (see "Cosmetic Raw Materials Standards 2nd Edition Commentary" published by Yakuji Nippo), and each has the following structural formula [A
] to [D]. Note that ordinary commercially available products can be used as these photosensitive elements.

It is 1 to 0.1% by weight. If this amount is too small, it is difficult to sufficiently prevent hair damage and obtain moist and smooth hair; on the other hand, if it is too large, there is no big difference in the effect and it is not economical. .
