Description

Oxidized hair dye composition

The present invention relates to an oxidative hair dye composition, and more particularly to a mixture of a higher aliphatic alcohol, a sorbitan surfactant, and a glucose surfactant as an active ingredient to significantly improve ammonia irritating taste and unpleasant odor. Oxidative hair dye composition.

In general, hair bleaching agents and hair dyes use an oxidizing agent such as a peroxide which acts to decolorize the hair, and the peroxide includes hydrogen peroxide, urea peroxide, hydrogen peroxide, melamine, and the like. Ammonia is an effective activator which accelerates the decolorization and dyeing of these peroxides, i.e., the oxidative destruction of melanin, and increases the oxidative coupling ratio of the dye. Further, in order to effectively function as a hair bleaching agent for hydrogen peroxide, it is necessary to adjust the pH to be alkaline. Although these pH adjustment effects can be achieved by other alkaline agents, ammonia can effectively have both an activator and a pH adjustment effect at the same time, and has the advantage of swelling hair, which is easy to remove excess after dyeing. For the best alkaline agent. Because of these effects, ammonia is most commonly used in hair bleaching agents or hair dyes.

As a highly volatile alkaline agent, ammonia, when mixing the first agent and the second agent, or applying hair, it will produce a pungent taste characteristic of ammonia, which not only irritates the eyes and skin, but also induces a very disgusting odor. People are very uncomfortable.

As a means of relieving ammonia stimulation, other organic/inorganic alkaline agents can be used, but the dyeing effect is less than that of ammonia, and it remains on the hair and scalp, which increases scalp irritation and hair damage. So far, ammonia is still the most widely used alkaline. Agent. Therefore, reducing ammonia irritating taste is the most important issue.

From the prior art related to the deodorization of ammonia, it is known that Epoleon N7C of Epoleon Co., Ltd. of Japan is commercially available, and the chemically neutralized method is used to mix appropriate acid-base components to chemically. Neutralizing ammonia to reduce the source of malodor, but when it is used in a hair dye, the content of ammonia itself is reduced, and there is a problem that the original purpose of using ammonia in the hair dye is hindered.

In addition, a sensory neutralization method in which an ordinary flavoring substance or a botanical composite extract (refer to Patent Document 1: Korean Laid-Open Patent Publication No. 2000-0025753) or a natural essential oil-menthol oil is attempted to be deodorized by adding an appropriate combination has been disclosed. Although the method maintains the ammonia content in the hair dye, the deodorizing effect is relatively weak and the alkalinity is extremely high, thereby seriously affecting the flavor component, the botanical extract component (plant composite extract), the natural essential oil component, etc. in the cosmetic. When the cosmetics are stored for a long period of time or when the cosmetics are used for a long period of time, the effect of suppressing and reducing the irritating smell of ammonia and the unpleasant odor (hereinafter referred to as "the taste-eliminating effect of the ammonia taste") is lowered, and there is a problem that the cosmetic is deteriorated.
