Description

Oxidative hair dye composition

The present invention relates to an oxidative hair dye composition, and specifically relates to a composition containing a mixture of a higher aliphatic alcohol, a sorbitan series surfactant, and a glucose series surfactant as an active ingredient for remarkably improving ammonia pungent smell and unpleasant smell Oxidative hair dye composition.

In general, hair decolorizers and hair dyes use oxidizing agents such as peroxides that decolorize hair, and the peroxides include hydrogen peroxide, urea peroxide, melamine hydrogen peroxide, and the like. Ammonia is an effective activator that can accelerate the decolorization and dyeing of hair by these peroxides, that is, the oxidative destruction of melanin, and can increase the oxidative coupling ratio of dyes. In addition, in order for hydrogen peroxide to function effectively as a hair bleaching agent, 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 two effects of activator and pH adjustment at the same time, and has the advantages of swelling hair and easy removal of excess parts after dyeing. Therefore, ammonia For the best alkaline agent. Because of these effects, ammonia is most commonly used in hair bleaches or hair dyes.

As a highly volatile alkaline agent - ammonia, when the first and second doses are mixed, or when the hair is applied, it will produce a unique irritating smell of ammonia, which not only irritates the eyes and skin, but also induces a very disgusting smell. People are very uncomfortable.

As a means to relieve ammonia irritation, other organic/inorganic alkaline agents can be used, but their dyeing effect is not as good as ammonia, and it remains on the hair and scalp, increasing scalp irritation and hair damage. So far, ammonia is still the most widely used alkaline agent. Therefore, reducing the irritating smell of ammonia is the most important issue.

From the prior art related to ammonia deodorization (deodorizing), it is known that Epoleon N7C of Epoleon Co., Ltd. in Japan is commercially available. This Epoleon N7C uses a chemical neutralization method to mix appropriate acid-base components to chemically Ammonia is neutralized to reduce the source of malodor, but when it is used in hair dyes, the content of ammonia itself is reduced, which hinders the original purpose of using ammonia in hair dyes.

In addition, a sensory neutralization method for deodorization by adding an appropriate combination of general fragrance substances or plant-based complex extracts (refer to Patent Document 1: Korean Publication No. 2000-0025753) or natural essential oil-peppermint oil has been disclosed. Although this method maintains the content of ammonia in the hair dye, the deodorizing effect is relatively weak and the alkalinity is extremely high, which seriously affects the fragrance components, plant extract components (plant compound extracts), natural essential oil components, etc. in cosmetics. Stability, so when the cosmetics are stored or used for a long time, the effect of suppressing and reducing the pungent and unpleasant smell of ammonia (hereinafter referred to as "ammonia deodorizing effect") will be reduced, and there is a problem of deterioration of cosmetics.
